Three-Circuit Single-Row Receptacle for Wire-to-Board Power
The Molex 2159131003 is a 3-position, single-row receptacle from the Mini-Fit SR (Standard Rack) series, designed as the wire-side half of a wire-to-board power interconnect. It uses a 4.20mm pitch — the standard spacing across the Mini-Fit family — and terminates via crimp contacts that are ordered separately.
Crimp Termination and Mating Half
This receptacle accepts female socket crimp terminals (sold separately) for 18-24 AWG wire, terminated with a standard Mini-Fit crimp tool. The mating male half is a Mini-Fit header with 4.20mm pitch, same circuit count — the latch lock on the receptacle engages the header's ramp for a positive, audible click that confirms full seating. For harness builders, the single-row layout simplifies wire routing in tight spaces compared to dual-row alternatives.
