The Molex 0436400200 is a 2-circuit plug housing from the Micro-Fit 3.0 43640 series, built for wire-to-board or wire-to-wire power interconnects where a positive-lock mate is required. The 0.118" (3.00mm) pitch matches the full Micro-Fit 3.0 family, so the board footprint and receptacle spacing are consistent across the series.
The male crimp terminals are ordered separately — the common fit is the Molex 43030 series pin terminal for 20-24 AWG wire. A buyer adding this to a BOM must include the terminal line item; the housing alone cannot complete a circuit. The crimp termination means the wire is attached to the terminal before insertion, then the terminal locks into the housing cavity. Panel-mount snap-in features let the housing clip into a cutout without hardware, which speeds harness assembly when the connector needs to be fixed to a chassis or bulkhead.
