It uses a 0.165\" (4.20mm) pitch with an identical 0.165\" (4.20mm) row spacing across two rows, giving the harness builder a standard grid for crimp-and-poke terminal insertion. The housing is moulded in natural polyamide (PA66) and carries a locking ramp on the mating face — the ramp engages with the matching receptacle housing to hold the pair together under vibration without a secondary latch. Contacts are not included with this housing; you order the male pin terminals separately (Molex 5556 series) and crimp them onto the wire before inserting into the cavity. ## What It Mates With and What Terminals to Order This plug housing accepts the Mini-Fit Jr male crimp terminals (Molex 5556 series, 20–24 AWG) and mates with the Mini-Fit Jr 5557 receptacle housing. The locking ramp on the plug snaps into the matching window on the receptacle — you'll hear the click when fully seated. Because the housing ships without contacts, the BOM line for this order code covers only the plastic body; the terminal part number and the wire gauge must be specified separately for the full crimp assembly.","metaTitle":"Molex Mini-Fit Jr 5559 0039013183 Plug Housing, 18 Pos","metaDescription":"Molex 0039013183 Mini-Fit Jr 5559 plug housing, 18 circuits, 4.20mm pitch, locking ramp, natural PA66.
