DDR4 questions buyers ask before design-in

Which DDR4 speed grades and densities can HGCHIPS supply?

4 / 8 / 16 / 32 Gb densities at 1.2 V in FBGA-78/96, in speed grades DDR4-2666, DDR4-2933 and DDR4-3200. Send the original part number and we confirm the matching HG part number and the fields that differ.

How do I verify a DDR4 replacement before design-in?

Work through the pin-to-pin checklist on the cross-reference page: density, organization, speed grade, voltage, package and temperature range. Any field we cannot map is flagged rather than assumed.

What are the sample and lead-time terms?

Samples from 10 pcs. Quotations are answered within 24 hours and in-stock items are dispatched from Shenzhen within 48 hours.
