What it is
The Molex 430450213 is a 2-circuit, dual-row board-to-wire header in the Micro-Fit 3.0 43045 series. 3.00 mm row spacing (0.118 in), through-hole kinked-pin solder termination, 4-wall shroud with a locking ramp and board guide feature. All two positions are loaded — every circuit slot carries a square male pin. Rated 8 A per circuit at up to 600 V.
Plating split and what it means
Mating-side contacts carry 15.0 µin (0.38 µm) gold over nickel; the solder-post side is 100.0 µin (2.54 µm) tin. The gold on the mating interface delivers the low contact resistance and repeatable matings the harness side needs; the thick tin on the post ensures a reliable solder joint without under-plating concerns. This dual-finish split is standard across the 43045 series and means the connector is suited for signal or moderate-power board-to-wire runs where the wire-side is mated and un-mated in service.
Mating half
The 430450213 is the board-mount half of a Micro-Fit 3.0 pair. The matching component is the corresponding 2-circuit Micro-Fit 3.0 plug housing with crimp terminals — confirm the housing order code matches the circuit count and keying option before committing. The 4-wall shroud and locking ramp provide polarisation and retention; the board guide feature aids alignment during wave or manual soldering assembly.
