10-circuit breakaway at 2.54 mm pitch
The 0022289102 is the 10-circuit member of Molex's KK254 breakaway header line, single-row, unshrouded, with a 0.100" (2.54 mm) pitch that matches the standard grid for prototyping and production boards. Gold-on-mating contacts rated for repeated insertion cycles, tin-on-post tails for solderability; the PA66 glass-filled housing carries a UL94 V-0 flammability rating.
Right-angle through-hole termination
The kinked-pin solder tails hold the header in place during wave soldering — the 0.135" (3.43 mm) post length suits standard 1.6 mm PCBs. Right-angle orientation places the mating axis parallel to the board, useful for edge-card or mezzanine layouts where vertical clearance is tight.
