Typical applications include automotive, industrial, medical, and telecommunications equipment where a reliable, field-serviceable power interconnect is required. The 0430451814 carries 18 circuits, against the 16 circuits of the 0430451610 at the same 3.00 mm pitch and same 8 A per circuit rating. The two-position difference is the only decision point — match the circuit count to your BOM line. If your harness needs 16 positions, the 0430451610 fits; if you need 18, this is the one. Pitch, current, voltage, and plating are identical.","metaTitle":"Molex Micro-Fit 3.0 0430451814 Header, 18 Circuits, 8A","metaDescription":"Molex Micro-Fit 3.0 header 0430451814, 18 circuits, 3.00mm pitch, 8A, 600V, gold-plated contacts, through-hole, UL94 V-0.
