Molex 1053112107 is a 7-position, single-row header from the Nano-Fit 105311 series, pitched at 2.50 mm — the same footprint as many automotive and industrial wire-to-board connectors. The 250 V rating and tin-on-tin contact interface suit it for power distribution and signal circuits in equipment that stays mated for long periods, where the tin surface doesn't see frequent fretting.
Mating and Stack Height — What It Connects To
This header mates with Nano-Fit 105311 receptacle housings and crimp terminals (sold separately). The shrouded 4-wall housing and latch holder provide polarization and a positive lock — the latch clicks audibly when seated, and the shroud prevents misalignment during blind mating in tight panels.
Peer Cross-Reference — 105311-2107
The only difference between 1053112107 and 105311-2107 is the dash in the part number — all key specs match: 7 positions, 2.50 mm pitch, tin plating, through-hole, latch holder, natural color, 21.30 mm stack height. Either MPN can fill the same BOM line.
