The Molex 430450625 is a 6-position dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnects. It carries 8 A per circuit at a 3.00 mm pitch, with a 600 V voltage rating, making it suited for distributing power within automotive, industrial, and telecom harness assemblies. The shrouded 4-wall housing with a locking ramp provides vibration-resistant retention when mated with the matching Micro-Fit 3.0 receptacle.
The 3.00 mm pitch gives enough creepage for the 600 V rating without forcing an oversized board footprint. Gold plating on the mating side at 15.0 µin (0.38 µm) supports repeated mating cycles and resists corrosion in environments where the connector sees field service or operates in a non-sealed enclosure. The tin-plated solder posts (100.0 µin / 2.54 µm) are standard for through-hole wave soldering. Board guide and board lock features aid alignment during through-hole insertion and provide mechanical retention against shear forces from cable strain — a practical detail when the header sits near a harness exit point on the PCB.
This header is specified for board-to-wire power distribution in automotive, general-purpose industrial, medical, and telecom equipment. The locking ramp and shrouded housing make it a common choice for harness assemblies that must stay mated under vibration inside an enclosure.
