10 positions, 2.54mm pitch — the BOM-fit anchor
The 86479-3: The 3A per-contact rating is conservative for the contact cross-section; at 3A the temperature rise stays within the UL94 V-0 thermoplastic housing limit. Right-angle orientation means the pins exit perpendicular to the board edge, keeping the mated cable assembly parallel to the PCB.
30µin gold vs 15µin gold — a real delta in the Mod II line
That extra thickness buys roughly twice the mating cycle life before the gold wears through to the nickel underplate. In a field-service connector that sees quarterly unmate/mate cycles, 30µin gold supports over a century of service at the contact interface. Compared to the 8-position 1-86479-6 and 6-position 1-86479-5, the 86479-3 is the only 10-position variant in this right-angle, unshrouded, 30µin gold configuration.
