The Molex 2035551116 is a 6-circuit, dual-row header from the CP-6.5 203555 series, designed for board-to-wire power applications. It carries 11.8 A per circuit at a 6.50 mm pitch, with a 600 VAC/DC rating — the wide pitch gives enough creepage for that voltage without forcing an oversized board footprint.
The 11.8 A per circuit is a power-level rating, not a signal-level one — each contact carries enough current for a motor feed or a DC rail. The 6.50 mm pitch is wide enough to route the board traces between the through-hole pads without necking down the copper.
