What This Housing Needs Before It Works
The Molex 5046930401 is a 4-circuit, single-row receptacle housing from the CP-3.3 504693 series. The critical note on this listing: contacts are not included. You order the housing and the crimp terminals separately — the Molex CP-3.3 female socket terminal (order code 5031490400 or equivalent) is the recommended mate.
Mating Half and Wire Prep
This receptacle mates with the CP-3.3 single-row header (male pin) of the same 4-circuit count and 3.30 mm pitch. The header is a through-hole PCB-mount part — the housing slides on and the latch holder engages. For the wire side, you need the female crimp terminals (sold separately), a hand crimp tool, and wire in the 20-24 AWG range. The crimp termination means you can replace individual contacts in the field without desoldering — useful when a wire gets pulled or chafed in a harness.
