The Molex 0430451625 is a 16-circuit, dual-row header from the Micro-Fit 3.0 43045 series. It's a board-to-cable/wire interconnect — a shrouded male pin header that mates with the matching Micro-Fit 3.0 receptacle housing to deliver power and signal in a locked connection. Typical applications span automotive, industrial, medical, and telecom harness assemblies where the locking ramp and 4-wall shrouding protect the contacts from vibration and misalignment.
The 3.00 mm pitch and matching 3.00 mm row spacing define the board footprint — the same as every Micro-Fit 3.0 dual-row header, so the pattern stays consistent across 8, 10, 12, 14, and 16-circuit variants. The 16 positions are all loaded, no optional empties. Rated 8 A per circuit at the stated voltage of 600 V. That's the standard Micro-Fit 3.0 power rating — each contact carries enough for a small motor or a branch supply line, not just signal duty. Through-hole termination with kinked pins — the kink locks the pin in the plated hole during wave solder.
The 4-wall shrouding means the male pins are recessed — no bent pins from a dropped harness.
