Board-to-wire receptacle for 1.50 mm pitch harnesses
The Molex 5031590900 is a 9-position single-row receptacle from the CLIK-Mate 503159 series, designed for board-to-wire applications at a 1.50 mm pitch. Its latch holder fastening keeps the mated pair locked under vibration, which is why it shows up in automotive, industrial, and lighting BOMs. The tin-plated forked contacts and kinked-pin through-hole termination suit moderate-cycle, cost-sensitive designs where gold flash isn't needed.
Pitch, position count, and temperature range
At 1.50 mm pitch and 9 positions, this single-row receptacle fits a compact board footprint — the 0.134 inch (3.40 mm) post length gives a solid solder joint for through-hole assembly. Insulation height of 0.313 inch (7.95 mm) and a board guide feature help align the mating header during assembly.
