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.
