20-Pin Ribbon-Cable Header with Eject Hooks
The 5499922-4: This is a 20-position, 2-row, 2.54mm pitch shrouded header from the AMP-Latch series — the standard footprint for IDC ribbon cable interconnects. The vertical through-hole orientation keeps the header standing upright on the board, and the 0.549-inch (13.94mm) insulation height clears the ribbon cable strain relief.
Pitch, Pinout, and Board Fit
0.100-inch (2.54mm) pitch and 0.100-inch row spacing — this matches the standard AMP-Latch IDC receptacle footprint. The 0.240-inch (6.10mm) mating pin length engages the full contact beam of the receptacle; the 0.110-inch (2.79mm) solder tail length suits a standard 1.6mm PCB thickness. Through-hole solder termination — the 100 µinch tin post finish wets well in wave or hand solder.
