Typical applications include automotive, general purpose, industrial, medical, and telecommunications equipment. The 12 circuits in a dual-row layout at 3.00 mm pitch define the board footprint — two rows of six pins each, with 0.118 in (3.00 mm) row spacing. ## Construction and Environmental Fit That covers underhood automotive and sealed industrial cabinet environments. ## How It Compares Within the Series Within the Micro-Fit 3.0 43045 family, the 430451214 (12 positions) sits alongside the 16-position 430451610 at the same 3.00 mm pitch and 8 A per circuit rating. The decision between them is driven purely by the circuit count on your BOM — the footprint, current capacity, and mating half are otherwise identical. Both use the same gold-plated contacts and locking ramp retention.","metaTitle":"Molex Micro-Fit 3.0 430451214, 12-Pos Header, 3 mm Pitch","metaDescription":"Molex 430451214 Micro-Fit 3.0 header, 12 circuits, 3.00 mm pitch, 8 A per circuit at 600 V.
