Executive summary
The April 2026 design lookup ranking on Supplyframe surfaces a broad cross-section of building block silicon. The top five parts by design lookups span temperature sensors, USB ESD protection, MOSFETs, LDO regulators, and serial EEPROM. Each part has a clear, actionable buyer story on Findchips today.
Three takeaways for buyers and design teams. First, the AD7314ARMZ and USBLC6-2SC6 both show very healthy authorized stock, so Findchips is an easy place to compare distributor pricing and lock in volume now while the curve is still flat.
Second, the AP2112K-3.3TRG1 is showing a 24 week lead time at one of the largest catalog distributors, so this is the part where buyers should take action on first.
Third, the AO3400A is up 275 percent year over year on design lookups with a 20 week DigiKey lead time, which means an early supply tightening warrants qualifying the UMW 8 week alternate as a second source in parallel.

Part 1: AD7314ARMZ. 10 bit digital temperature sensor
- Manufacturer: Analog Devices Inc.
- Product class: Sensors and Transducers.
- Package: 8 lead MSOP.
- April 2026 design rank: 1 (Activity Index 100, +11.43 percent month over month, +40.54 percent year over year).
- Sourcing rank: not in the top 30. The signal is design side only, which means engineers are evaluating this part for new designs but procurement has not yet caught up. Buyers who source ahead of that wave will lock pricing and stock before any squeeze.
Authorized stock is very healthy. Sponsored Analog Devices listings show 35,799 units at $4.56 (1), $2.95 (10), $2.06 (100). Newark and Avnet variants show stock in the 333 to 1,053 range with cut tape and tape and reel options.
The AD7314ARMZ-REEL7 reel variant has 1,053 units at $3.59 (1), $2.70 (10). Multiple authorized distributors carry the part.
Engineer Q&A
What is the typical application circuit for the ad7314armz?
Answer: Use the AD7314ARMZ as a single chip SPI temperature node. Tie VDD to 3.3 V, ground SCLK and DOUT to the host MCU SPI port, add a 100 nF decoupling capacitor between VDD and GND, and connect CS to a host GPIO.
The 10 bit output streams a signed 2 complement temperature word over SPI with no external calibration required. The MSOP 8 footprint drops onto sensor boards where space is tight. See and compare AD7314ARMZ datasheet and authorized sources on Findchips.
Is the ad7314armz pin compatible with the ad7414 or tmp75?
Answer: No. The AD7314ARMZ uses an SPI interface in an 8 lead MSOP. The AD7414 and TMP75 are I2C parts in SOT 23 6 and SO 8. If the design calls for I2C, the ADT7410 in 8 lead MSOP is the closest Analog Devices alternate.
For SPI continuity, stay with the AD7314ARMZ family. Compare AD7314ARMZ and ADT7410 availability on Findchips.
Should i design in the ad7314armz for a new product in 2026?
Answer: Yes for SPI based, low cost temperature monitoring with 10 bit resolution. Authorized stock is at multi tens of thousands across distributors with stable pricing under $3.00 at 100 piece quantities.
The design lookup ranking is up 40.54 percent year over year, which usually precedes a sourcing surge by one to two quarters. Lock in volume now if the design will go to production this year. Check live availability for AD7314ARMZ .

Buyer Q&A
Who has the ad7314armz in stock right now?
Answer: At least seven authorized distributors carry the AD7314ARMZ as of May 8, 2026. The largest visible quantity is the sponsored Analog Devices direct listing at 35,799 units.
Newark shows 333 units and Avnet shows the AD7314ARMZ-REEL7 reel with 1,053 units. Buy from authorized sources for full warranty and traceability. Compare AD7314ARMZ authorized distributor stock on Findchips.
What is the cheapest authorized distributor for the ad7314armz at 100 quantity?
Answer: The sponsored Analog Devices direct channel is currently lowest at $2.06 per unit at 100 quantity. Newark sits at $2.52 (25). For volumes above 1,000, the reel variant AD7314ARMZ-REEL7 will typically beat cut tape pricing.
Confirm currency and tariff treatment on the Findchips listing before placing the PO. Compare AD7314ARMZ pricing at 100 quantity on Findchips.
What is the lead time for the ad7314armz at 5,000 units in q3 2026?
Answer: Lead time is short today. With 35,000 plus units in the sponsored channel and another several thousand across Newark and Avnet, a 5,000 piece order should ship from existing stock for delivery within standard distributor SLAs.
The risk is that design lookup activity is up 40.54 percent year over year, so this stock cushion can compress quickly. Place the order this month to avoid that compression. Check AD7314ARMZ lead time and reel availability on Findchips.

- The USBLC6-2SC6 protects USB 2.0 D+ and D− data lines against ESD events. The +93 percent YoY is large for a part this mature and reflects continued growth in USB type C and consumer hardware designs.
Stock is abundant. The sponsored ST direct entry shows 79,788 units at $0.371 (1), $0.28 (10), $0.26 (25). The tape and reel listing carries 144,000 units at $0.066 (24,000 reel). The USBLC6-2SC6Y variant (lead free) shows 264,839 units at $0.589 (1), $0.510 (25). Pricing is stable and supplier coverage is broad.
Engineer Q&A
Is the usblc6-2sc6 the right esd protection for usb 2.0 high speed data lines?
Answer: Yes. The USBLC6-2SC6 is purpose built for USB 2.0 D plus and D minus protection with 3.5 pF line capacitance, low enough to preserve high speed signal integrity at 480 Mbps. It provides IEC 61000-4-2 ESD protection with transient clamping behavior suitable for USB 2.0 interfaces.
For USB 3.x SuperSpeed pairs, switch to a lower capacitance part such as the ESDA6V1U2 (0.5 pF) instead. View USBLC6-2SC6 datasheet and stock on Findchips.
What is the difference between the usblc6-2sc6 and the usblc6-2p6?
Answer: Footprint and pin count, not protection. The USBLC6-2SC6 is a SOT 23 6 device. The USBLC6-2P6 is a smaller SOT 666 (DFN) for tighter board layouts. Electrical specs are equivalent.
Pick the SC6 when hand assembly or rework is needed, and the P6 when board area is the tighter constraint. Compare USBLC6-2SC6 and USBLC6-2P6 packaging options on Findchips.
Is there a drop in replacement for the usblc6-2sc6 if i need shorter lead time?
Answer: Yes. The Diodes Incorporated DT1240A 4U2 and the Onsemi ESD7104 are pin compatible with the SOT 23 6 footprint and offer comparable USB 2.0 performance.
The DT1240A 4U2 typically ships with a shorter standard distributor lead time than the ST part. Cross check the clamping curve before committing. View USBLC6-2SC6 alternates on Findchips.

What is the cheapest authorized source for the usblc6-2sc6 at 24,000 reel?
Answer: Avnet currently shows the USBLC6-2SC6 tape and reel at $0.0656 per unit on a 24,000 piece reel. Other authorized distributors land between $0.066 and $0.075 at the same volume tier. Negotiate based on the Findchips authorized listings rather than the sponsored panel. Compare USBLC6-2SC6 reel pricing on Findchips.
Is the usblc6-2sc6 active or eol?
Answer: Active. STMicroelectronics has not announced an EOL or NRND for the USBLC6-2SC6 family as of May 8, 2026. The part shows healthy production activity, with more than 144,000 units on tape and reel across authorized channels and broad distributor coverage.
Safe to design in for production through at least 2027. Check USBLC6-2SC6 lifecycle status on Findchips.
Lead time for the usblc6-2sc6 at production volume?
Answer: Short. Stock across authorized distributors exceeds 480,000 units when the SOT 23 6 and lead free Y variants are added together. A 50,000 piece production order should ship from existing inventory at the listed reel pricing. Confirm currency and tariff handling on the chosen Findchips listing before issuing the PO. Check real time USBLC6-2SC6 lead time on Findchips.
Next step: Lock in USBLC6-2SC6 reel pricing on Findchips.
USBLC6 family: When to Use
These are the most commonly sourced USBLC6 variants. Buyers should default to the USBLC6-2SC6 SOT 23 6 footprint where board area allows, and use the variants below when a specific constraint applies.
| Part | Manufacturer | Package | When to Use | Check Availability |
|---|---|---|---|---|
| USBLC6-2SC6 | STMicroelectronics | SOT 23 6 | Default. Best stock and broadest distributor coverage. | Check USBLC6-2SC6 |
| USBLC6-2SC6Y | STMicroelectronics | SOT 23 6 (Y, lead free) | Use when a lead free Pb mark is required. Even higher stock than base SC6. | Check USBLC6-2SC6Y |
| USBLC6-2P6 | STMicroelectronics | SOT 666 (DFN) | Use when board area is the binding constraint. Smaller footprint, slightly tighter supply. | Check USBLC6-2P6 |
Recommended Next Step: Confirm USBLC6 family availability.
Part 3: AO3400A. N channel logic level MOSFET
- Manufacturer: Alpha and Omega Semiconductor.
- Product class: Transistors.
- Package: SOT 23 3. April 2026 design rank: 5 (Activity Index 49, +63.83 percent month over month, +275.61 percent year over year).
- The AO3400A is a 30 V, 5.7 A logic level N channel MOSFET widely used as a low side switch in consumer electronics, motor drivers, and battery management. The +275.61 percent YoY signals a strong return to designs that switched away during the 2024 supply tightness.
Mixed stock with a clean alternate path, DigiKey carries 208,486 units of the authorized AO3400A at $0.0865 (30,000 reel) with a 20 week stated lead time. UMW (an alternate equivalent supplier) shows 5,795 units at $0.0647 with an 8 week lead time, which is meaningfully shorter. Smaller authorized listings show 348 units at $0.073 to $0.099. The 20 week DigiKey lead time is the buyer signal to act on.
Engineer Q&A
Is the AO3400A a true logic-level MOSFET for 3.3 V gate drive?
Answer: Yes. The AO3400A is rated VGS(th) max 1.4 V and turns on hard at 2.5 V, so a 3.3 V GPIO is a clean drive level. RDS(on) is 35 mOhm at VGS 10 V and approximately 50 mOhm at VGS 4.5 V.
Use it for 3.3 V or 5 V MCU controlled low side switching up to roughly 5 A continuous in a SOT 23 footprint with proper thermal copper. View AO3400A datasheet and stock on Findchips.
What is the best drop in replacement for the ao3400a right now?
Answer: The Onsemi NTR4003N and the Diodes Incorporated DMN3404L are the cleanest pin compatible drop ins. Both share the SOT 23 3 footprint and the same 30 V, logic level VGS(th) profile.
For shorter lead time at low cost, the UMW AO3400A equivalent is a same part, alternate supplier path that ships in 8 weeks against the DigiKey authorized 20 week lead time. Compare AO3400A and pin compatible alternates on Findchips.
Should i redesign around the ao3400a or stick with it for the next product cycle?
Answer: Stick with it for now. The 275 percent YoY design lookup growth shows it is firmly the default low side N channel MOSFET in SOT 23 for new designs. As long as the design accepts the 20 week authorized lead time or the 8 week UMW alternate path, no redesign is justified.
Keep the NTR4003N footprint compatible on the PCB as a contingency. View AO3400A and NTR4003N pin compatible alternates on Findchips.
Next Step: AO3400A alternates and delivery times on Findchips.
Buyer Q&A
Alternate source for the ao3400a with shorter lead time than digikey?
Answer: Yes. UMW carries the AO3400A equivalent at 5,795 units in stock with an 8 week lead time at $0.0647 (30,000 reel). DigiKey authorized stock is much deeper (208,486 units) but quotes a 20 week lead time on new orders.
If the build window is shorter than 20 weeks, source the UMW listing first. Compare AO3400A authorized and alternate supplier lead times on Findchips.
What is the cheapest authorized distributor for the ao3400a at 30,000 piece reel?
Answer: DigiKey is currently the lowest authorized at $0.0865 per unit on a 30,000 piece reel of AO3400A. Smaller cut tape orders run $0.073 to $0.099 across mid tier distributors.
For volume buys, the reel pricing is the right benchmark. Compare AO3400A reel pricing on Findchips.
Is there a shortage of the ao3400a in 2026?
Answer: Not yet, but the 20 week authorized lead time at the largest catalog distributor is a leading signal. Combined with the 275 percent YoY design lookup increase, this is the early shape of a supply tightening.
Buyers with Q3 or Q4 2026 builds should place orders now and qualify the UMW 8 week alternate as a second source. Check AO3400A lead times and alternate suppliers on Findchips.
Do This Next: Lock in AO3400A reel pricing and qualify the alternate supplier on Findchips.
Part 4: AP2112K-3.3TRG1. 3.3 V, 600 mA LDO regulator

- Product class: Power Circuits (LDO). Package: SOT 25 5.
- April 2026 design rank: 9 (Activity Index 41, +10.34 percent month over month, +146.15 percent year over year).
- The AP2112K-3.3TRG1 is a fixed 3.3 V, 600 mA LDO that has become a default low quiescent regulator for IoT and battery powered designs. The 146 percent YoY ranking growth puts it well into the early shortage warning band.
The current snapshot of this part on Findchips is tightening. The Diodes Incorporated direct listing shows 9,000 units at $0.073 (48,000 reel). DigiKey reports the AP2112K-3.3TRG1 as Temporarily out of stock with a 24-week lead time on new orders, priced at $0.093 (30,000) reel).
Engineer Q&A
What is the typical application circuit for the ap2112k-3.3trg1?
Answer: Use the AP2112K-3.3TRG1 as a fixed 3.3 V LDO between a 4.2 V to 6 V input and a 3.3 V load up to 600 mA. Place a 1 microfarad ceramic capacitor on VIN, a 1 microfarad ceramic on VOUT (X5R or X7R, low ESR), and tie the EN pin high or to a host GPIO for shutdown control.
The SOT 25 footprint suits compact battery powered boards. View AP2112K-3.3TRG1 datasheet and authorized sources on Findchips.
What is the best drop in replacement for the ap2112k-3.3trg1 right now?
Answer: The Microchip MCP1700 3.3 (250 mA) covers low current loads, and the Torex XC6206P332MR provides a comparable SOT 23 5 footprint at 200 mA. For full 600 mA pin compatible coverage in SOT 25, the Diodes AP2210N 3.3TRG1 is the closest authorized alternate.
Given the 24 week DigiKey lead time on the AP2112K-3.3TRG1, qualifying one of these alternates this week is the right move. See AP2112K-3.3TRG1 and AP2210N alternates on Findchips.
Is the ap2112k-3.3trg1 still safe to design into new products in 2026?
Answer: Yes for designs that can absorb a 24 week supply window or qualify a second source. The part is in active production and Diodes Incorporated direct stock holds 9,000 units. The risk is concentration on one authorized channel.
New designs should specify the AP2112K-3.3TRG1 as the primary and the AP2210N 3.3TRG1 (same SOT 25 footprint) as the formally qualified alternate. Check AP2112K-3.3TRG1 stock on Findchips.

Part 5: M24C02-WBN6P. 2 Kbit serial I2C EEPROM
- Manufacturer: STMicroelectronics.
- Product class: Memory.
- Package: 8 lead PDIP. April 2026 design rank: 11 (Activity Index 38, +90.48 percent month over month, +53.85 percent year over year).
- The M24C02-WBN6P is a 2 Kbit (256 by 8) serial I2C EEPROM in a through-hole PDIP package. The continued design ranking growth is unusual for a through-hole part in 2026 and likely reflects industrial maintenance, legacy retrofit, and educational kit demand.
Stock is visible across multiple distributors but pricing visibility is uneven. Listings show 22 units, 271 units (DE stock), 7,263 units, 12,000 units, and 25,755 units at five different sources. Several listings carry stock numbers but no published pricing on the Findchips card, which is a content gap to flag.
Engineer Q&A
Is the m24c02-wbn6p the right choice for a new 2026 industrial design?
Answer: Only when through hole assembly is mandated. The M24C02-WBN6P is a PDIP 8 part. For any new SMT design, the M24C02-RMN6TP (SO 8 surface mount) is the same silicon in a modern footprint with deeper authorized stock.
Use the WBN6P only for legacy refresh, repair, or kit assembly contexts. M24C02-WBN6P and M24C02-RMN6TP packaging.
What is the difference between the m24c02-wbn6p and the m24c02-rmn6tp?
Answer: Package only. Both are 2 Kbit (256 by 8) serial I2C EEPROMs from STMicroelectronics on the same silicon and instruction set. The WBN6P is PDIP 8 through hole. The RMN6TP is SO 8 surface mount.
Electrical specs, pinout numbering, and I2C protocol are identical. Pick by assembly process. View M24C02 family options on Findchips.
Should i use the m24c02-wbn6p for a hobbyist or educational kit?
Answer: Yes. The PDIP form factor is ideal for breadboard prototyping, educational kits, and through hole production. With more than 25,000 units listed across authorized and broad line distributors on Findchips, a kit run of a few thousand pieces ships from existing stock.
Confirm the chosen distributor publishes pricing before issuing a PO. Check M24C02-WBN6P kit quantity stock on Findchips.
Next step: View M24C02-WBN6P stock for kit quantities on Findchips.
Buyer Q&A
Who has the m24c02-wbn6p in stock right now?
Answer: At least five distributors. Visible Findchips inventory (May 8, 2026) shows 22 units (one tube), 271 units in DE stock, 7,263 units, 12,000 units, and 25,755 units across separate listings.
Confirm price and currency before issuing the PO: Check M24C02-WBN6P distributor stock on Findchips.
What is the lead time for the m24c02-wbn6p at 5,000 units?
Answer: Short. Current visible inventory suggests many 5,000 piece orders could ship from existing stock depending on allocation and reel configuration. PDIP packaging tends to ship faster than SO 8 in 2026 because demand is structurally lower and inventory turnover is slower.
Confirm packaging (tube versus tray) at the chosen distributor before confirming the PO. See the part on Findchips.
What are alternate sources for the m24c02-wbn6p in surface mount?
Answer: The M24C02-RMN6TP is the same silicon in SO 8 surface mount and is the recommended SMT path. The Microchip 24LC02B P is a pin compatible PDIP 8 alternate from a different manufacturer.
Both can be cross referenced from the M24C02-WBN6P Findchips listing. Compare M24C02-WBN6P and 24LC02B P alternates on Findchips.
