The Molex 5051510900 is a 9-circuit receptacle housing from the DuraClik 505151 series, designed for wire-to-board interconnect in applications that demand a positive lock and a wide operating temperature range. The 2.00 mm pitch keeps the board footprint compact while allowing enough creepage for the 125°C rated environment — typical for under-hood automotive modules, industrial sensors, and outdoor control units. The single-row layout with a latch holder provides an audible click on mate, resisting vibration-induced disconnect in engine compartments or machinery enclosures.
Mating Half and Locking
This receptacle mates with the corresponding DuraClik 505151 pin header (through-hole or SMT, depending on the header variant). The latch holder engages with the header's locking ramp — the housing slides on until the latch snaps, and the holder prevents accidental release from cable pull or vibration. The free-hanging (in-line) mounting means the receptacle sits on the wire harness, not on the board; the header is the board-mounted half.
