The Molex 430450628 is a 6-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire interconnects in automotive, general-purpose, industrial, medical, and telecom equipment. It carries 8 A per circuit at a 3.00 mm pitch, with a 600 V voltage rating — the pitch and shrouding provide enough creepage for that voltage without forcing an oversized board footprint. The mating contacts are gold-plated at 15.0 µin (0.38 µm), which supports repeated mating cycles in field-service applications, while the solder posts receive a 100.0 µin (2.54 µm) tin finish for reliable soldering. The through-hole mounting and 0.125" (3.18 mm) post length suit standard PCB thicknesses.
Mating half and sourcing
This header mates with the corresponding Micro-Fit 3.0 receptacle housing (e.g., the 43025 series) using crimp terminals — stock both halves or neither, because an orphan header on the shelf is dead stock.
