The Molex 5046930203 is a 2-circuit receptacle housing from the CP-3.3 504693 series, built for free-hanging (in-line) wire-to-wire or wire-to-board connections where the terminals are crimped onto leads and then inserted into the housing. The housing alone ships — you source the matching female socket terminals separately, crimped onto your wire. The 3.30 mm pitch (0.130") is wider than the common 2.54 mm header pitch, so verify your board footprint or mating connector matches this spacing before committing the BOM line.
Fit and Retention — the Latch Holder Matters
That makes this housing suited for applications where the connection sees movement or mechanical shock: inside an automotive junction box, on an industrial sensor harness, or in a portable equipment cable assembly.
Termination and Mating Half
The housing accepts the matching CP-3.3 crimp terminals (order separately). The mating half is the corresponding CP-3.3 header, also in a 2-circuit, 3.30 mm pitch configuration. No soldering, no special tooling beyond a hand crimper and an insertion tool.
