Frequently asked questions

HGD34G16S21 — can it drop in without board changes?

No board changes. HGD34G16S21 is designed as a pin-to-pin drop-in: package and pin-out are checked field by field against the original datasheet, so it fits the existing PCB and firmware. Typical use is second-sourcing, EOL cover and allocation shortages.

Which parameters should I verify before a replacement?

Verify the spec fields listed above — density, organization, speed grade, voltage, package and temperature range — against the original part number, then run a small pilot batch before volume. Any field we cannot match is stated rather than assumed.

HGD34G16S21 — samples and lead time?

Samples from 10 pcs, credited against the first order. In-stock items ship from Shenzhen within 48 hours; long-lead projects can be price-locked. Parts are 100% inspected before shipment and batch test data is available for IQC.
