What this header is
What it mates with — and what is not included
The 430451024 is the board-mount half only. A full assembly BOM requires the matching Micro-Fit 3.0 plug housing and the individual crimp terminals that accept the wire gauge. The header does not bundle contacts or a backshell — if you are quoting a build-to-print harness, confirm the receptacle housing P/N and terminal P/N are on the same purchase order as the header. The square pin contact shape and the kinked solder pin are specific to this series — cross-series headers may share the 3.00 mm pitch but the keying geometry and pin shape are Molex Micro-Fit 3.0 proprietary, so verify the matching half is from the same series before substituting. All 10 positions are loaded — there is no partial-load or odd-gauge position configuration on this part number; confirm your circuit count matches exactly.
