KK 254 Top-Entry Socket Header — What It Is
The 22-02-2255 is a Molex KK 254 PC Board Connector, a top-entry female socket header. It sits in the KK 254 family, which uses a 2.54 mm pitch — the same 0.100-inch spacing that matches standard perfboard and IDC ribbon cable. The top-entry orientation means the mating plug inserts perpendicular to the PCB, keeping the z-height low for tight enclosures.
ROHS3 compliant, so it passes the materials compliance gate for EU and most global markets.
