The Molex 430450202 is a 2-position, dual-row header from the Micro-Fit 3.0 43045 series, configured as a board-to-cable/wire interconnect. The 3.00 mm pitch and dual-row layout match the standard Micro-Fit 3.0 footprint, and the 8 A per circuit rating at 600 V positions it as a power interconnect for harness assemblies in automotive, industrial, medical, and telecom equipment.
The 8 A per circuit rating at 600 V means each contact carries enough current for a DC power rail or moderate-load circuit — this is not a signal-only header.
Compared to the 430450201, which is the single-row 2-position variant at the same 3.00 mm pitch, the 430450202 uses a dual-row layout. This means the 430450202 occupies a wider footprint on the board but keeps the same 2-circuit count — the choice between them comes down to whether the mating receptacle is a single-row or dual-row housing.
