Three-Circuit Squba 1.8 Receptacle for Wire Harness Assembly
The Molex 2042204004 is a 3-position receptacle from the Squba 1.8 204220 series, designed for free-hanging (in-line) wire-to-wire or wire-to-board harness applications. The 1.80mm pitch keeps the assembly compact while leaving room for the locking mechanism.
Pitch, Positions, and Locking — What Drives the Fit
The 1.80mm pitch is tighter than the common 2.54mm or 3.00mm spacing, so the mating header and the wire crimp terminals need to match that centerline exactly — no fudging with a 2.00mm part. Three positions in a single row: that's one circuit per position, no shared pins. The latch lock is a molded ramp on the housing that snaps over a ramp on the header; you'll hear it click when it seats. It's not a screw lock or a friction-only fit — it's designed to stay mated in a moving assembly.
No end-of-life notice or last-time-buy on record. The base product number is 204220; the -4004 suffix identifies the 3-position, black, tray-pack variant.
No soldering, no PCB footprint: this is a field-terminatable, in-line connector.
