20-Position Mini-Fit Jr 5559 Plug Housing — 4.20mm Pitch, Panel Mount
It carries a 0.165" (4.20mm) pitch in a dual-row layout with the same 0.165" (4.20mm) row spacing, giving the 20 positions a compact but serviceable footprint for medium-current power distribution in harness assemblies. Mounting is panel-mount snap-in, so the housing clips into a cutout without hardware, and the crimp termination means the user selects and installs the terminals separately.
Contacts Not Included — What Fits
This housing accepts the standard Mini-Fit Jr male crimp terminals, which are ordered separately as Molex 5556 series pins. The 20-position count means a full harness requires 20 individual pin terminals plus the mating receptacle housing and its female terminals. The crimp termination suits automated or bench-top harness tooling — the terminal is inserted from the rear and retained by the housing's internal lance, with the locking ramp securing the mated pair.
