The Molex 5023510701 is a 7-circuit receptacle housing from the DuraClik 502351 series, built for wire-to-board interconnects where a positive lock and a compact 2.00 mm pitch are required. The housing accepts female socket crimp terminals — contacts are ordered separately — and mates with the corresponding DuraClik header to complete the harness. The latch holder on the housing locks audibly when mated, giving vibration-resistant retention for automotive interior, industrial control, and appliance wiring where the connector sees movement or shock.
Key Specs That Drive the Fit
The 2.00 mm pitch keeps the board footprint tight — useful when routing several signal or low-power circuits through a single connector without eating up PCB real estate. The single-row, 7-position layout matches a 7-circuit BOM line exactly; one housing per harness leg. Free-hanging (in-line) mounting means this receptacle sits on the wire bundle, not soldered to the board, so the harness builder crimps terminals into the housing and snaps it onto the header. The PBT insulation handles -40°C to 105°C, which covers under-hood automotive compartments, industrial cabinets near motors, and outdoor telecom enclosures that see seasonal temperature swings. The black colour is standard for the series — no colour-coding for keying on this variant.
Mating and Termination — What You Need to Order Separately
This housing does not include contacts. The harness builder must source the matching DuraClik female crimp terminals — typically Molex 56134 series or equivalent — and crimp them onto the wire before inserting into the housing cavities. The latch holder on the housing engages with the header's locking ramp; a tactile click confirms full mate. No secondary lock or TPA is listed for this housing, so terminal retention relies on the crimp terminal's own lance engaging the housing cavity.
How 5023510701 Compares to 5023510802
The 5023510802 is the 8-position sibling in the same DuraClik 502351 series, same 2.00 mm pitch, same latch holder and free-hanging form. If the BOM calls for 7 circuits, the 0701 is the correct fit; the 0802 adds one unused cavity if pressed into service, which is wasteful but mechanically compatible with the same header family.
