The 8 A per circuit rating at 600 V places this firmly in the power distribution class, not signal-only duty. The locking ramp fastening provides positive retention against vibration-induced disconnection — relevant for automotive, industrial, and telecommunications environments where the harness sees movement. ## Position Count and Pitch — Fit Check At 14 positions across two rows spaced 3.00 mm apart, this header occupies a board footprint that matches the 14-circuit Micro-Fit 3.0 receptacle housing.","metaTitle":"Molex 430451419 Micro-Fit 3.0 Header, 14-Circuit SMT, 3mm Pitch","metaDescription":"Molex 430451419 Micro-Fit 3.0 SMT header, 14 positions, dual-row, 3.00mm pitch, 8A, 600V, gold plating.
