The 430450214: The 3.00 mm pitch gives enough creepage for the 600 V rating without forcing an oversized board footprint — the dual-row layout keeps the header compact. 8 A per circuit is the per-contact current limit at the rated temperature rise; the tin-plated solder tails (100 µin) handle the board-level termination without issue.
Position count in the series
At 2 positions, this is the smallest circuit count in the Micro-Fit 3.0 header family — a natural fit for a single power pair or a sense/signal loop where the BOM calls for exactly two circuits.
