The 77317-104-68LF: All 68 positions are loaded, so the footprint is full — no breakaway gaps to manage.
Contact Interface and Current Rating
The post tails are tin-plated at 78.7 µinch (2.00 µm), which solders cleanly into standard through-hole pads. Rated 3 A per contact. In a 68-position header, the practical current per circuit is limited by the total bundle temperature rise, but at 3 A the individual contact stays within the housing material's thermal limit across the full -65°C to 130°C operating range.
