The Molex 5046930604 is a 6-position receptacle housing from the CP-3.3 504693 series, built for in-line wire-to-wire or wire-to-board harnesses. The 3.30 mm pitch gives it a bit more room between contacts than the common 3.00 mm Micro-Fit spacing — useful when you're running 18-20 AWG and need the extra creepage.
The listing carries a clear note: Contacts Not Included. You'll need the matching CP-3.3 female crimp terminal (Molex 503149 series or equivalent) to populate the 6 cavities. Ordering just the housing and expecting a finished connector is the most common BOM mistake on this part.
The 5046930604 mates with the CP-3.3 series plug header (male pin housing). The single-row 6-position layout keeps the harness slim; the latch holder gives a tactile lock confirmation when mated.
