The Molex 0874390500 is a 5-circuit receptacle housing from the Pico-SPOX 87439 series, a compact wire-to-board interconnect family built for dense, low-power harnesses. The 1.50 mm pitch keeps the board footprint small, and the single-row layout with a locking ramp gives positive retention in applications where vibration or accidental snagging is a concern — think consumer appliance control boards, LED lighting modules, or automotive interior sub-assemblies.
Wiring and Termination
The housing accepts female socket contacts that are crimped onto the wire and then inserted into the cavity. Contacts are not included with the housing — they must be ordered separately as a distinct line item. The crimp termination is field-serviceable: the locking ramp releases the terminal with a small tool, so a mis-crimped wire can be replaced without scrapping the whole housing.
Mating Half and Keying
This receptacle mates with the matching Pico-SPOX 87439 series pin header, which is a through-hole or surface-mount right-angle board-mount header. The locking ramp on the receptacle engages a corresponding latch on the header for audible, vibration-resistant retention. No keying or polarization feature beyond the single-row geometry — the 1.50 mm pitch and 5-circuit count must match the header layout exactly.
