DDR Memory Replacement Overview — 146 part numbers

HGCHIPS covers 146 DDR-family part numbers (DDR3 71 / DDR4 35 / LPDDR4·4X 39 / DDR2 1) as pin-to-pin replacements for Samsung, SK hynix, Micron, Nanya and Winbond memory. 137 are in volume production; 9 further parts are spec-matched (production status to be confirmed in writing by our FAE). Package and ball map are verified against the original datasheet, so no PCB change is required — suited to second-source qualification, EOL and allocation cases.

How to qualify a replacement

• Match density and organisation first (e.g. 4Gb x16, not 4Gb x8);
• Match the speed grade (a faster part can run slower, not the other way round);
• Check voltage (1.5V vs 1.35V for DDR3) and temperature grade (commercial / industrial / AEC-Q100);
• Verify package and ball map; ask for samples (from 10 pcs) and per-lot test reports;
• Any part number can be checked in the model finder.
