The Molex 2159131006 is a 6-circuit, single-row receptacle from the Mini-Fit series, built for wire-to-board power interconnects. It uses a 0.165" (4.20mm) pitch — wide enough to carry moderate current per circuit without crowding the board layout. The housing is black polyamide (nylon) with a latch lock fastening system that holds the mated pair together under vibration, a step up from a friction-only housing. It terminates via crimp contacts (sold separately), and the free-hanging (in-line) mounting means it lands on a wire harness, not a PCB.
Mating Half and Termination
This receptacle mates with the corresponding Mini-Fit header (male pin) at the same 4.20mm pitch. The latch lock on the receptacle engages with the header's locking ramp — you'll hear it click when fully seated. The crimp termination requires the matching Mini-Fit female socket terminal, which is ordered separately and crimped onto 18-24 AWG wire before insertion into the housing. No soldering, no PCB footprint — this is a field-serviceable harness connection.
