HGD31G16S16 is offered by HGCHIPS as a second-source candidate for Samsung K4B1G1646I-BCNB (DDR3, 1 Gbit, 64Mx16). Density and organization are matched against our cross-reference data; the remaining parameters are checked field by field against the original manufacturer datasheet — the status of every field is shown below. Samples start at 10 pcs with lot-level test reports.
On K4B1G1646I-BCNB the comparison currently shows a difference on: Speed Grade: DDR3-2133 vs DDR3-1600. Until our FAE has confirmed the difference is acceptable for your platform, treat this part number as a sourcing candidate rather than a drop-in replacement.
We only mark a field as matched when it has been verified against the original manufacturer's public datasheet. Fields still under verification are shown as such rather than copied from a similar part number.

Density and organization are matched against our own cross-reference data. Speed grade, voltage, package and temperature grade are verified against the original manufacturer's public datasheet during FAE review; request the completed comparison sheet for this part number. 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.
100% inspection and burn-in at our own Shenzhen test center, with traceable lot-level reports.
Datasheet-level comparison and application support from our Taiwan and Shenzhen engineering team.
HGD31G16S16 is offered as a second-source candidate for Samsung K4B1G1646I-BCNB, not as a drop-in replacement: our field-by-field comparison currently shows a difference on Speed Grade: DDR3-2133 vs DDR3-1600. Density (1 Gbit) and organization (64Mx16) are matched against our own cross-reference data; the remaining parameters are confirmed field by field against the original manufacturer datasheet during FAE review. Ask us for the completed comparison sheet for this part number.
We publish only what we can verify. For K4B1G1646I-BCNB the density and organization are confirmed. Speed grade, voltage, package and temperature grade are either confirmed from the manufacturer datasheet or still in verification — the table above shows the status of each field.
The replacement is built to the same density, organization and footprint intent as the original, 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.
Samples start at 10 pcs, with sample cost 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.
Send your target quantity and platform — we confirm the field-by-field comparison against the original datasheet, share test reports and quote within 24 business hours.
