## HGD31L16C16 — common questions

### What does HGD31L16C16 stand for?

HGD31L16C16 is an HGCHIPS part number: HGD + generation (3) + density (1) + voltage position (L = low voltage) + organisation (64Mx16) + brand position (C = CXMT) + speed grade (DDR3-1600).

### Which original brand does the CXMT line serve?

HGCHIPS builds this line for CXMT part numbers: the brand position of the part number is C. Send us the original part number and we return the matching code together with the field-by-field comparison sheet.

### Is the CXMT line in stock?

Stock lines ship within 48 hours from Shenzhen; non-stock and long-lifecycle programmes are quoted with a confirmed lead time. Samples start at 10 pcs and sample cost is credited against your first production order.

### Do I need to change my PCB or firmware?

These parts are built to the same density, organisation and footprint intent as the original specification, so no PCB or firmware change is intended. Always qualify on your own platform before volume use — we provide samples from 10 pcs and lot-level test reports for that purpose.

### What documentation comes with the shipment?

Each lot ships with traceable inspection records, and the field-by-field comparison against the original datasheet is available on request.
