Against the 12-position 430451210 at the same 3.00 mm pitch and 8 A rating, the 430452419 doubles the circuit count for applications needing more I/O on the same footprint pitch. The choice between them comes down to the BOM position count — the board footprint, current per circuit, and mating receptacle family are identical, so the swap is a straight position-count decision.","metaTitle":"Molex Micro-Fit 3.0 430452419, 24 Pos Header, 3mm Pitch, SMT","metaDescription":"Molex 430452419 Micro-Fit 3.0 header, 24 circuits, 2 rows, 3.00mm pitch, SMT, gold mating finish, rated 8A, 600V.
