19-position unshrouded header, 2.54 mm pitch
The 0022288191 is the 19-circuit member of Molex's KK254 breakaway header line, unshrouded for board-to-board or cable duty. Tin-plated mating contacts, through-hole right-angle mounting, and a UL94 V-0 glass-filled nylon housing suit it for automotive, medical, and telecom applications.
Pitch, footprint, and routing
The 2.54 mm pitch and single-row layout keep the board footprint narrow — the 19 positions occupy 48.26 mm of board edge. The unshrouded design allows the mating half to approach from either side, simplifying wire routing in tight enclosures.
