The 5499922-1: This is a 10-position, 2-row, shrouded header from the AMP-Latch series, designed to mate with IDC ribbon-cable receptacles. The 0.100-inch (2.54 mm) pitch matches standard ribbon cable conductor spacing — pitch has to match the ribbon, or the IDC contacts bite between conductors instead of onto them. Post tails are tin-plated at 100.0 µinch (2.54 µm) for reliable solder wetting.
Board-fit and footprint details
Through-hole termination with a 0.110-inch (2.79 mm) post length. The 0.549-inch (13.94 mm) insulation height and 0.639-inch (16.23 mm) overall contact length set the z-height budget above the board. The latch lock/eject hooks, long, engage the mating IDC receptacle's locking ears. Watch pin-one every press — the keying slot is the orientation guide.
