Possible Alternative — Verify · Verify on Host

Summary

SK hynix DDR5 embedded family for functional cross-reference. Prefer H5CGD8AG8DX018 single-PN page when that exact part is on the BOM. Ball map and training must be validated on the target SoC.

Parameter alignment

Key handbook fields side by side — confirm package, grade, and firmware against the datasheet for your build.

Parameter Loongtion SK hynix
Density 16Gb (×8) Family-dependent
Package WBGA-82 Verify package
Data rate 4800 / 5600 / 6400 MT/s Speed-bin dependent
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 SK hynix, 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 SK hynix. Qualify Loongtion once so allocation, long lead times, or a future EOL on HMCG94MEB* / H5CGD8AG8* (DDR5 embedded family) 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°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.

  • Next-gen industrial controllers
  • Edge gateways and IPC platforms
  • High-bandwidth embedded compute

FAQs for this cross-reference

What does “Possible Alternative — Verify” mean for HMCG94MEB* / H5CGD8AG8* (DDR5 embedded family)?

We do not publish a single verified ordering PN for every incumbent SKU in this family. Loongtion YZ5GG16W-9CXDQ-M(O) 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 quote after verification?

Yes. After we confirm the closest Loongtion PN against your BOM line, send the board name, temperature grade, and quantity for a quote.
