What it is and where it sits
The Molex 430450802 is the 8-circuit member of the Micro-Fit 3.0 43045 series — a dual-row, right-angle board-mount header with a full four-wall shroud and locking ramp. Pitch is 3.00 mm, row spacing matches at 3.00 mm, and all 8 positions are fully loaded. The insulation is glass-filled LCP rated UL94 V-0, and the board-lock feature anchors the header during wave or hand-solder assembly — the solder-side paste-out condition the unshrouded alternative always fails.
What the ratings mean for the fit
Current rating is 8 A per contact — that is a per-contact ceiling, not a derated total bus — and the 30.0 µin gold on the mating side is what buys the cycle life here, not the 100.0 µin tin on the solder tail. Voltage rating is 600 V. Contact material is brass alloy.
