What it is
The Molex 430450815 is the 8-circuit member of the Micro-Fit 3.0 43045 series — a dual-row, shrouded header rated 8 A per circuit at 600 V with tin-plated contacts on both the mating face and the solder tail. Surface-mount termination with board lock, housed in glass-filled LCP to UL94 V-0.
What the ratings mean for your BOM
Mating half and termination
The header accepts the matching Micro-Fit 3.0 receptacle housing with the corresponding 8-circuit dual-row footprint; the square pin contact shape indexes within the housing cavity. Solder-side termination is SMT — confirm the board pad metallurgy is compatible with tin-solder assembly and that the 0.390 inch (9.91 mm) insulation height clears the component keep-out on your layout.
