What this is
The Molex 430450228 is the 2-circuit member of the Micro-Fit 3.0 43045 series — a dual-row, vertical-mount, through-hole header with a board guide and a locking ramp on the mating face. Gold plating on the mating interface (15.0 µin (0.38 µm) thick) grades down to a 100.0 µin (2.54 µm) tin deposit on the solder post side. The housing is black glass-filled liquid crystal polymer rated UL94 V-0.
What drives the selection
Where this class is used
Board-to-cable power distribution in automotive control modules, industrial automation equipment, medical instruments, and telecom infrastructure — anywhere a compact 3 mm pitch header carries meaningful current between a PCB and a wire harness. The UL94 V-0 rating and LCP material support designs that need flame-retardant housing in enclosed equipment.
Lifecycle and sourcing posture
The 430450228 carries an Active product status and ROHS3 Compliant designation — no end-of-life notice or last-time-buy date is on record. No official successor order code appears in the available data. Sourcing is quoted to order against the BOM quantity; confirm position count and mating half before committing a BOM line.
