HGD4M32S21 is a pin-to-pin compatible replacement for Micron MT53E512M64D2HJ-046. It matches the original on density (32 Gbit), organization (x64), speed grade (LPDDR4-2133), voltage (1.8/1.1/1.1 V) and package (VFBGA-200), so no PCB or firmware change is required. Samples start at 10 pcs with lot-level test reports.
Every field below is compared line by line against the original manufacturer's public datasheet before a part is offered as a replacement.

| Temperature Grade | Commercial (0~+95C) | Commercial (0~+95C) | ✔ Same |
Compatibility is based on electrical and mechanical comparison against the original manufacturer's public datasheet. Always qualify on your platform before volume use; test reports and application support are provided.
When the original is on allocation or past end-of-life, HG parts ship from physical stock — stock lines in 48 hours from Shenzhen.
Every lot ships with traceable validation records for your incoming QA.
Datasheet-level comparison and application support from our Taiwan and Shenzhen engineering team.
Yes. HGD4M32S21 is engineered as a pin-to-pin compatible replacement for Micron MT53E512M64D2HJ-046: LPDDR4/X 32 Gbit x64 in a VFBGA-200 package. Ball map, electrical specification and timing are compared against the original manufacturer's public datasheet, and the part is functionally validated before shipment.
No PCB or firmware change is intended. The part is designed for the same footprint and ball map as Micron MT53E512M64D2HJ-046. Always qualify the replacement on your own board before volume use — we provide samples from 10 pcs and lot-level test reports for that purpose.
Samples start at 10 pcs. Sample cost is credited against your first production order.
Stock lines ship within 48 hours from Shenzhen. Non-stock and long-lifecycle programs are quoted with a confirmed lead time — send your target quantity and we reply within 24 business hours.
Our Taiwan engineering team compares density, organization, speed grade, voltage, package and temperature grade against the original datasheet, then the part is functionally validated on mainstream platforms, with traceable per-lot records.
