Summary
SK hynix H5CGD8AG8DX018 — 16Gb DDR5 industrial-class Functional Alternative to Loongtion YZ5GG16W. Both sides list −40~+85°C class coverage; confirm package/ball map and speed bin on the host.
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) | 16Gb (×8) |
| Package | WBGA-82 | FBGA / WBGA ×8 (verify) |
| Voltage | 1.1 V | 1.1 V |
| Temperature | −40°C to +85°C | −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 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 H5CGD8AG8DX018 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 −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, 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.
- Next-gen industrial controllers
- Edge gateways and IPC platforms
- High-bandwidth embedded compute
FAQs for this cross-reference
What does “Functional Alternative” mean for H5CGD8AG8DX018?
It means Loongtion YZ5GG16W-9CXDQ-M(O) is a documented functional or form-factor path for BOM exploration versus SK hynix H5CGD8AG8DX018 — 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 SK hynix?
Yes — that is a common international OEM pattern. Qualify the Loongtion PN on your board, keep SK hynix 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 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.
