Summary
Transcend MTS420/MTS400 — verified M.2 2242 SATA III compact SSDs (public product sheets). Note: research “MTS420P” was not confirmed as an official Transcend PN; use MTS420/MTS400. Loongtion 2242 SATA is a functional form-factor path — many Transcend SKUs are 0~70°C; confirm wide-temp need vs Loongtion industrial grades.
Parameter alignment
Key handbook fields side by side — confirm package, grade, and firmware against the datasheet for your build.
| Parameter | Loongtion | Transcend |
|---|---|---|
| Form factor | M.2 2242 | M.2 2242 |
| Interface | SATA III 6 Gb/s | SATA III 6 Gb/s |
| Temperature | Wide-temp industrial grades | Often 0~70°C (verify industrial SKU) |
| Capacity | See product page | Series-dependent |
Why evaluate Loongtion for this PN
Cross-reference is not only for discontinued parts — many OEMs qualify a Loongtion path as a second source next to Transcend, then use it for dual-sourcing, allocation relief, or future EOL coverage.
- Second source — not only an EOL story Use this mapping to dual-source alongside Transcend. Qualify Loongtion once so allocation, long lead times, or a future EOL on TS240GMTS420S does not stop your line.
- Functional Alternative path for BOM review This page documents the Loongtion PN, key parameter alignment, and compatibility type. Treat it as engineering guidance — confirm package, speed/firmware, and temperature on your host before production.
- Industrial temperature grades where listed Loongtion lists Wide-temp industrial grades for this line. Match the ordering PN to your environmental requirement (commercial, wide-temp, or Extreme-temp / GJB where offered).
- Endurance / grade options for write-heavy duty Where the product line offers pSLC or higher-endurance grades, evaluate them for logging, boot, and always-on industrial workloads — not every incumbent SKU ships the same endurance class.
- Direct engineering and small-batch pilots Request the datasheet with your incumbent PN, board, and temperature grade. Typical engineering reply is within one business day on China business days — useful for pilots before you lock an AVL dual-source.
Typical applications
Common equipment contexts where engineers search for this part family or a compatible alternative.
- Industrial PCs and edge servers
- Wide-temp NVMe storage upgrades
- Automation and vision systems
FAQs for this cross-reference
What does “Functional Alternative” mean for TS240GMTS420S?
It means Loongtion Industrial M.2 2242 SATA DRAM-less line is a documented functional or form-factor path for BOM exploration versus Transcend TS240GMTS420S — not a blanket semiconductor interchangeability warranty. Confirm interface, package, capacity/density, firmware, and temperature on your host.
Can I use Loongtion as a second source while still buying Transcend?
Yes — that is a common international OEM pattern. Qualify the Loongtion PN on your board, keep Transcend as primary if required, and use Loongtion for allocation relief, cost/lead-time balance, or future EOL coverage.
What must I verify before substituting?
Match the critical interface and mechanical constraints (package / form factor, protocol, capacity, voltage, speed, endurance class). Then validate firmware behavior, power, and Wide-temp industrial grades on the target platform.
Can I evaluate the part before ordering?
Send the incumbent PN, application, temperature grade, and quantity. Engineering will confirm the closest Loongtion PN, evaluation terms, and lead time.
