Summary
Winbond W957A6MB LPDDR4X (0.6V) — Possible Alternative to Loongtion YZDB*. Package may be FBGA178 or FBGA200 depending on SKU — ball maps differ; do NOT claim Pin-to-Pin until the exact package on the customer BOM is confirmed.
Parameter alignment
Key handbook fields side by side — confirm package, grade, and firmware against the datasheet for your build.
| Parameter | Loongtion | Winbond |
|---|---|---|
| Density | 2 / 4 / 8 GB | 2–8 GB (verify SKU) |
| Package | FBGA178 / FBGA200 (match host) | FBGA178 or FBGA200 — confirm on BOM |
| Voltage (core) | 0.6V LPDDR4X | 0.6V LPDDR4X |
| Temperature | −40~+85°C | −40~+85°C (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 Winbond, 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 Winbond. Qualify Loongtion once so allocation, long lead times, or a future EOL on W957A6MB does not stop your line.
- Possible Alternative — Verify 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~+85°C for this line. Match the ordering PN to your environmental requirement (commercial, wide-temp, or Extreme-temp / GJB where offered).
- Direct engineering, samples, and small-batch pilots Request datasheet and samples 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 PLC / DCS controllers
- CNC and motion controllers
- Industrial PCs and HMIs
- Long-lifecycle embedded boards
- Medical and test equipment (where grade allows)
FAQs for this cross-reference
What does “Possible Alternative — Verify” mean for W957A6MB?
We do not publish a single verified ordering PN for every incumbent SKU in this family. Loongtion YZDB5CCBM-EA-A / YZDB6CCBM-EA-A / YZDB7CCDM-EA-A is a possible alternative by protocol / form factor / density class — host verification is required before production. Send your exact BOM PN and we will shortlist the closest Loongtion part.
Is this a guaranteed drop-in?
No. Treat this page as a starting point for dual-sourcing or EOL exploration. Confirm package/ball map, firmware, capacity, temperature, and endurance on your board. Engineering can help once you share the exact incumbent ordering code.
What should I send so you can verify a match?
Incumbent full ordering PN (not only the family name), capacity, temperature grade, form factor or package, interface, and the target host / application. Photos of the part marking or a datasheet excerpt help.
Can I request a sample after verification?
Yes. After we confirm the closest Loongtion PN against your BOM line, use Request sample with board name, temperature grade, and quantity.
