Pitch and Position Count — First Board-Fit Check
The 57102-S06-04LF: The 2.00mm pitch is tighter than the common 2.54mm (0.100") standard, so the board routing density is higher — verify the trace escape between pads before committing the layout.
Rated 2A AC/DC per contact at 200V AC/DC — the per-contact current is conservative for a 2.00mm pitch header, keeping the temperature rise within the UL94 V-0 thermoplastic housing limit. The 200V rating covers most low-voltage signal and power distribution inside equipment; for higher voltage or mains isolation, a connector with a higher creepage distance is needed.
