Summary
CXMT CXD2A8G8MA — DDR3 8Gb domestic incumbent (knowledge-base §2.2). Map to Loongtion YZ38G16SDB for wide-temp CN BOM dual-sourcing. NOTE: production-list drafts that labelled this as DDR4→YZ48G08V were incorrect; this PN is DDR3. Confirm organization, package, and ball map before design-in.
Parameter alignment
Key handbook fields side by side — confirm package, grade, and firmware against the datasheet for your build.
| Parameter | Loongtion | ChangXin (CXMT) |
|---|---|---|
| Density | 8Gb (×16 FBGA96 path) | 8Gb (verify organization) |
| Interface | DDR3 (SSTL) | DDR3 (SSTL) |
| Voltage | 1.35V / 1.5V | 1.5V (typical) |
| Temperature | −40°C to +85°C (WT grades) | −40°C to +85°C |
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 ChangXin (CXMT), then use it for dual-sourcing, allocation relief, or future EOL coverage.
- Keep long-lifecycle boards alive When ChangXin (CXMT) CXD2A8G8MA is hard to source or marked EOL, a documented Loongtion path helps MRO and long-life OEM programs avoid a full redesign — after board qualification.
- 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 (WT grades) 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 “Cross-Reference” mean for CXD2A8G8MA?
It means Loongtion YZ38G16SDB-9INN-M(0) (8Gb ×16 FBGA96) is a documented functional or form-factor path for BOM exploration versus ChangXin (CXMT) CXD2A8G8MA — 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 ChangXin (CXMT)?
Yes — that is a common international OEM pattern. Qualify the Loongtion PN on your board, keep ChangXin (CXMT) 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 (WT grades) on the target platform.
Can I get a sample for evaluation?
Yes. Request a sample with incumbent PN, application, temperature grade, and qty. Engineering will confirm the closest Loongtion PN and shipping plan.
