Rated 8 A per circuit at 600 V, the 430450415 carries power-level current — the tin-plated contacts (60.0 µin on the mating side) are sized for the DC rail or moderate-load circuits, not signal-level duty. This header mates with any Micro-Fit 3.0 receptacle housing that matches the 4-circuit, dual-row layout — the 43025 series housings are the standard mate. The receptacle accepts crimp terminals (20-24 AWG) or pre-terminated IDC wires. Don't order half a connection — pair this header with its receptacle and the correct crimp terminals for a complete harness. The 0.118 in (3.00 mm) row spacing matches the pitch, so the footprint is a simple 2x2 grid. No through-hole soldering or press-fit tooling needed. ## Comparison with the 6-circuit sibling The 4-position 430450415 sits alongside the 6-position 430450615 in the same Micro-Fit 3.0 SMT header family. Both share the 3.00 mm pitch, 8 A per circuit rating, 600 V rating, shrouded 4-wall design, board lock, and locking ramp. The difference is the circuit count — 4 positions vs 6 — which changes the board footprint length and the number of circuits available in the harness. Choose the 4-position when the BOM calls for a 4-circuit power or signal interface; step up to the 6-position when more I/O is needed without changing the connector family.","metaTitle":"Molex Micro-Fit 3.0 430450415, 4-Pos SMT Header, 3 mm Pitch","metaDescription":"Molex 430450415 Micro-Fit 3.0 SMT header, 4 circuits, 3.00 mm pitch, 8 A, 600 V, shrouded 4-wall, board lock, locking ramp, UL94 V-0.
