Summary
512 GB NAND Flash domestic incumbent — handbook lists alongside Micron MT29F4T08EULGEM4-ITF:G for YRK8J152NY.
Parameter alignment
Key handbook fields side by side — confirm package, grade, and firmware against the datasheet for your build.
| Parameter | Loongtion | SM Micro (Guowei) |
|---|---|---|
| Capacity | 512 GB | 512 GB (verify) |
| Package | BGA152 | BGA152 (verify) |
| Temperature | −40°C to +85°C | Industrial (verify) |
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 SM Micro (Guowei), 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 SM Micro (Guowei). Qualify Loongtion once so allocation, long lead times, or a future EOL on SM29F512G08SJM does not stop your line.
- Cross-Reference 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 −40°C to +85°C for this line. Match the ordering PN to your environmental requirement (commercial, wide-temp, or Extreme-temp / GJB where offered).
- 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.
- Solder-down raw NAND designs
- Industrial storage controllers
- Long-lifecycle embedded systems
FAQs for this cross-reference
What does “Cross-Reference” mean for SM29F512G08SJM?
It means Loongtion YRK8J152NY is a documented functional or form-factor path for BOM exploration versus SM Micro (Guowei) SM29F512G08SJM — 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 SM Micro (Guowei)?
Yes — that is a common international OEM pattern. Qualify the Loongtion PN on your board, keep SM Micro (Guowei) 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 −40°C to +85°C 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.
