The Molex 5016463800 is a 38-circuit receptacle housing from the iGrid 501646 series, built for wire-to-board applications where a positive latch lock keeps the pair mated under vibration. The 2.00 mm pitch and dual-row layout give it a compact footprint for a 38-position interconnect, but the first thing to know is that contacts are not included — this is the empty shell, and you order the crimp terminals separately. The latch lock on the sides clicks into the mating header's ramp, so you get an audible confirmation of full engagement on the harness line.
Contacts not included. This housing accepts a female socket crimp terminal — source the correct Molex iGrid terminal for your wire gauge and crimp it before inserting into the housing.
Mating Half and Fit Check
This receptacle housing mates with the iGrid 501646 series male header — a through-hole or surface-mount pin header with the same 2.00 mm pitch and dual-row layout. The 38-position count is the one to match against your BOM circuit count; the 2.00 mm pitch determines the board footprint for the header side. There is no current rating on the housing itself — the current capability comes from the crimp terminal you install and the wire gauge you use.
