Board-fit and position count
The 5-146762-2: The 2.54 mm grid matches a wide range of industry-square-pin headers, so the board layout engineer can route traces between pads without necking down. All 10 positions are loaded, so there is no placeholder pin — every circuit carries signal or power from the first mate.
Current and plating for signal duty
The tin-on-tin contact finish is cost-effective for low-cycle-count applications.
Mates with any 0.025" square pin header on 0.100" pitch, including TE's AMPMODU Mod IV and BergStik II series headers. The square contact shape ensures four-point wiping on each pin.
How it compares to nearby siblings
If your board requires surface-mount assembly or needs two extra circuits, that part is the swap — but the SMT footprint and forked contact geometry differ from this through-hole square-contact design. For a lower position count with gold-plated mating contacts, consider 1376775-2 (5-position) or 1376775-3 (3-position) — both rated 3 A with 8 µinch gold on the mating face, which buys more mating cycles at a higher per-contact cost.
