The Molex 430450215 is the 2-position, dual-row member of the Micro-Fit 3.0 43045 series — a surface-mount header designed for board-to-wire power interconnects. It carries 2 positions loaded across 2 rows at a 3.00 mm pitch, with a shrouded 4-wall housing that protects the male square pins during mating. The 8 A per-circuit current rating and 600 V voltage rating place it firmly in the power distribution class for this pitch, not signal-only duty.
The 3.00 mm pitch gives enough creepage for the 600 V rating without forcing an oversized board footprint — the row spacing of 3.00 mm matches the pitch, so the dual-row layout fits a standard 6.00 mm-wide pad pattern.
The 430450215 is the 2-position version against the 430450214, which is the 4-position member of the same Micro-Fit 3.0 dual-row SMT header family. Both share the 3.00 mm pitch, 8 A per circuit rating, 600 V rating, tin plating, board lock, and locking ramp. The only decision-relevant difference is the position count: 2 positions vs 4 positions. No other spec changes between them.
