What this connector is
The Molex 430450828 is the 8-circuit dual-row member of the Micro-Fit 3.0 43045 family — a shrouded board-to-cable wire header with a through-hole solder tail, designed for power and signal distribution in harness assemblies across automotive, industrial, medical, and telecom applications. The connector pitches at 3.00 mm on two rows with 8 positions loaded all, and carries an 8 A per-circuit current rating at the full 600 V — a rating combination that puts this well above typical signal-only headers of the same pitch.
The plating split is the key spec
The mating interface carries gold at 15.0 µin (0.38 µm) thickness, while the solder-post side is tin at 100.0 µin (2.54 µm) — a grade choice that governs lifecycle, not just contact resistance. The gold mating finish delivers the durability needed for repeated matings in harness service; the thick tin on the post side ensures a reliable solder joint with good solder-wetting margins on a through-hole land. With both sides rated, the buyer can commit to this part on a mixed-signal or power harness without second-guessing the plating grade.
Mechanical retention and shrouding
The shroud extends on all four walls, and the fastening type is a locking ramp — meaning the housing latch clicks into a ramp feature on the header to resist vibration pull-out. A board guide feature helps locate the header in the footprint during assembly, reducing oblique seating before the solder reflow cycle. The insulation body is black liquid crystal polymer glass-filled, rated UL94 V-0, which sets the flammability class for in-cabinet or vehicle harness routing.
Sourcing posture
The 430450828 carries an Active lifecycle status and ROHS3 Compliant designation — cleared for automotive and industrial BOM entry without a substitute search. No official successor or cross-reference appears in the record for this MPN. The part is quoted to order against the BOM quantity; confirm pinout and mating half compatibility before committing a design position.
