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.","metaTitle":"Molex Mini-Fit 2159131003 Receptacle, 3-Circuit, 4.20mm","metaDescription":"Molex 2159131003 Mini-Fit SR receptacle, 3 circuits, single row, 4.20mm pitch, latch lock, -40°C to 105°C.
