Board Layout Fit: Pitch, Orientation, and Footprint
The 77317-814-08LF: The dual-row arrangement with 0.100" row spacing gives an 8-position layout that fits a 2×4 pattern on the PCB. The 0.106" (2.69 mm) post length provides enough solder tail for a reliable through-hole joint on standard 1.6 mm boards, while the 0.394" (10.00 mm) mating pin length gives good wipe depth in the mating receptacle.
