It uses a single row of square pins on a 0.100" (2.54 mm) pitch — the classic footprint for a standard.100" grid PCB layout.
The right-angle solder tails are 0.220" (5.58 mm) long, and the mating pin length is 0.230" (5.84 mm), which gives a standard engagement depth for a shrouded receptacle.
The black insulation color is standard for this series.
The 68498-122HLF carries the same 0.100" pitch, single-row layout, and 30.0 µin gold plating as the 3-position 68016-103HLF, but with 22 positions instead of 3 — so the footprint is just longer along the board edge. The current rating on this 22-position variant is 5 A per pin, matching the 5 A rating on the 3-position 68705-103HLF and 68024-103HLF. The position count is the only real selection variable here: pick the number that matches your circuit count.
