The 0022284044: On the board, the 0.320" (8.13mm) mating pin length gives good wipe before the contact bottoms out.
Rated for board-to-board or cable-to-board duty, this header mates with KK254 crimp socket housings (series 6471, 2695) carrying 22–30 AWG wire. Applications span automotive, general-purpose, medical, and telecommunications — the gold plating and V-0 nylon suit environments where repeated mating and flame rating are both specified.
Within the Molex KK254 series, the closest alternative is the 0022284045 (5-position) or 0022284043 (3-position) — same pitch, plating, and unshrouded form factor, differing only in circuit count. No direct 4-position replacement from another manufacturer is listed.
