It is a free-hanging (in-line) housing with a 4.20mm pitch and matching 4.20mm row spacing, designed to accept crimp female socket terminals. The latch lock provides a positive, audible click when mated with the corresponding header, giving the harness builder a tactile confirmation of full engagement. The housing is molded from black PA66 (Nylon 6/6) and is sold in bulk packaging. The most important thing to know before adding this to a BOM: contacts are not included. You need to order the matching crimp terminals separately — typically Molex 5556 series or equivalent — and the wire gauge selection will depend on the current draw per circuit. ## Mating and Termination Checklist This receptacle housing mates with any standard Mini-Fit Jr 5557 series header of the same 4.20mm pitch and 8-position count. The latch lock on the housing engages with the corresponding ramp on the header, holding the pair together under vibration without needing a secondary screw or clip. Termination is crimp-style: you insert the pre-crimped female socket terminal into the housing cavity until the terminal's retention lance locks into the housing. The PA66 housing provides the insulation and mechanical support; the crimp terminal carries the current. For a reliable harness, confirm the terminal part number and the recommended crimp tooling from the Mini-Fit Jr application tooling guide.","metaTitle":"Molex Mini-Fit Jr 5557 0039039082, 8-Pos Receptacle Housing","metaDescription":"Molex 0039039082 Mini-Fit Jr 5557 8-position receptacle housing, 4.20mm pitch, latch lock, black PA66.
