It carries a 0.100" (2.54 mm) pitch and a matching 0.100" row spacing, so the footprint is a standard 0.100" grid — no surprises for the board layout engineer.
At 0.100" pitch with tin plating, 5 A is the practical ceiling for a single contact — above that, the temperature rise in a 68-position body would push past the housing limit. The 110 V rating is conservative for the pitch and creepage distance; this header can handle typical logic-level and low-power bus voltages without issue. The 0.125" (3.18 mm) solder post length is a standard through-hole dimension for a 0.062" board — the post protrudes enough for a reliable fillet without bottoming out in the plated hole.
