The Molex 0430200810 is an 8-circuit plug housing from the Micro-Fit 3.0 43020 series, designed as the male half of a wire-to-board or wire-to-wire power interconnect. It carries a 0.118" (3.00mm) pitch in a 2-row arrangement, with a locking ramp that provides audible and tactile feedback during mating — a practical check against incomplete engagement in harness assembly. Glow wire compliance per IEC 60335-1 means this housing is accepted in appliance builds where a fault-current fire risk must be contained.
The most common mistake on this part is assuming the contacts ship with the housing. The Micro-Fit 3.0 system uses a separate crimp terminal (Molex 43030 series for the male pin) that is ordered by wire gauge. Without those terminals, the plug has no electrical path. The BOM line for 0430200810 should always be paired with a terminal line item.
This plug mates with the Micro-Fit 3.0 receptacle housing (Molex 43025 series) — the 8-circuit, 2-row version. For panel mounting, the snap-in feature secures the housing into a panel cutout without hardware.
