It uses the standard 0.100" (2.54 mm) pitch on both rows and between rows, matching the footprint of legacy through-hole boards and ribbon-cable IDC receptacles. All 46 positions are loaded — no skipped pins to track.
The 0.100" pitch is the same as legacy 0.1" grid prototyping boards and BergStik-compatible receptacles. The 46 positions in two rows means the board footprint is 23 holes per row at 2.54 mm spacing — confirm your PCB layout matches that column count. The 5 A per contact rating is derated by the UL94 V-0 housing; at elevated ambient temperatures the current should be reduced per the manufacturer's derating curve.
This unshrouded header mates with any standard 0.100" pitch dual-row receptacle that accepts 0.025" square pins — common choices include BergStik II socket strips or IDC ribbon connectors. Termination is through-hole solder; the 0.120" (3.05 mm) post length suits standard PCB thicknesses from 0.062" to 0.093". The overall contact length of 1.040" (26.42 mm) gives enough standoff for the mating receptacle to clear components on the board.
