What this header is
The Molex 430450628 is the 6-circuit, dual-row member of the Micro-Fit 3.0 43045 family — a shrouded board-to-cable header rated 8 A per circuit at 600 V, terminated via through-hole solder. Pitch is 0.118 inch (3.00 mm) with the standard dual-row row spacing matching the mating pitch, giving a 2-row × 3-position grid. The housing is black glass-filled LCP, UL94 V-0 rated, with an insulation height of 0.390 inch (9.91 mm) above the board surface and a post tail length of 0.125 inch (3.18 mm). Fastening is a locking ramp — the ramp draws the receptacle housing in and holds it against vibration before the primary latch snaps. Four-wall shrouding plus integral board guides prevent the mating housing from rotating or seating off-axis, which matters in any harness or panel where the connector sees cable pull or service access.
Contact plating and what it means for duty
Where it sits in the Micro-Fit 3.0 family
Micro-Fit 3.0 is a mid-range wire-to-board power connector series — the 430450628 is the header half that solders to the PCB and mates with the matching Micro-Fit 3.0 plug housing and crimp terminal on the wire side. Applications span automotive, industrial automation, medical equipment, and telecom infrastructure where the 600 V rating and the dual-row footprint give a compact power-distribution node at the board edge. The 6-position count positions this header between the lower-circuit-count variants in the same series and the larger multi-row variants — check that your BOM calls for exactly 6 circuits before committing; position count is the primary BOM-matching parameter in this family.
