Board-to-Wire Power Header for Dense Harness Assemblies
The Molex 0430452007 is a 20-circuit, dual-row, surface-mount right-angle header from the Micro-Fit 3.0 43045 series. The 3.00 mm pitch and 8 A per circuit rating make it a fit for power distribution in automotive, industrial, medical, and telecom equipment where the board space is tight but the current demand is real.
The 8 A per circuit rating is the headline current at the contact level — the 3.00 mm pitch gives enough creepage for the 600 V rating without forcing an oversized board footprint. The gold mating contacts (15.0 µin) handle repeated mating cycles in corrosive environments better than tin, while the tin post finish (100.0 µin) is standard for solder joint reliability.
Mounting and Termination for SMT Assembly
This is a surface-mount, right-angle header with solder termination.
No official cross-reference or direct substitute is listed — the 20-position count and 3.00 mm pitch define the footprint, so confirm the BOM position count and the mating half before committing.
