Board-to-Wire Power Header for Tight Enclosures
The Molex 430451022 is a 10-position, dual-row right-angle header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnect applications. Its 3.00 mm pitch and 4-wall shrouding provide a robust, polarized mating interface for the matching Micro-Fit 3.0 receptacle housings. This connector is qualified for use in automotive, general purpose, industrial, medical, and telecommunications equipment, as listed in the official application scope.
Right-Angle vs. Vertical: The 430451022 and 430450022
The primary decision between the 430451022 and its sibling 430450022 comes down to board orientation. Both are 10-position, dual-row headers at 3.00 mm pitch with the same 8 A per circuit rating, gold-plated contacts, and board locks. The 430451022 is a right-angle header, meaning the mating axis is parallel to the PCB, ideal for board-edge cable exits in low-profile enclosures. The 430450022 is a vertical header, where the mating axis is perpendicular to the board, better suited for top-down cable routing in taller enclosures. Choose the one that matches your mechanical layout — the electrical specs are identical.
