FAQ

K4B series — common questions

What replaces the K4B series?

HGCHIPS supplies 26 PIN2PIN compatible replacements covering the K4B series from Samsung. Each replacement is compared field by field against the original datasheet — density, organization, speed grade, voltage, package and temperature grade.

Do K4B replacements need a PCB change?

No. The replacements share the original footprint and ball map, so the intent is a drop-in swap without a PCB or firmware change. Always qualify on your own platform before volume use.

What is the minimum order quantity?

Samples start at 10 pcs, with sample cost credited against your first production order.
