Connector overview
The Molex 0430450625 is the 6-circuit member of the Micro-Fit 3.0 43045 series — a dual-row board-to-cable header rated 8 A per circuit at up to 600 V, housed in black glass-filled LCP with UL94 V-0 flammability classification. The contact design splits plating by zone: gold 15.0 µin (0.38 µm) on the mating interface where cycle life matters, and 100.0 µin (2.54 µm) tin on the solder post side where solderability and joint robustness are the constraint. The four-wall shroud and locking ramp prevent cable-side extraction under vibration — a meaningful constraint in automotive and industrial harness assemblies where intermittent mate-back is a known failure mode. Board guides and kinked pins position the header during solder paste reflow and hold it in plane while the joint solidifies — without them the housing drifts out of coplanarity and the outer rows lift.
Mating and termination
This is a male pin header — the mate is the matching Micro-Fit 3.0 female receptacle housing accepting discrete crimp terminals; the 0.118" (3.00mm) row spacing and dual-beam female contact geometry make it specific to the 43045 family. Termination is through-hole kinked pin with solder; the 0.125" (3.18mm) post length suits standard PCB thickness and the kinked tip holds position in the plated through-hole during paste settlement. Rated for General Purpose, Industrial, Medical, Automotive and Telecommunications applications — the 600 V rating covers these market segments, but confirm the system operating voltage against this ceiling before committing.
Sourcing
Supplied in tray packaging — specify the correct packaging quantity and confirm the through-hole footprint against the board stack-up before releasing to manufacturing.
