The 77311-102-00LF: The 0.230" (5.84mm) mating pin length gives enough reach for a standard female socket housing, while the 0.135" (3.43mm) solder tail clears a 1.6mm PCB with room for a wave-solder fillet. The post finish is tin, which wets well in a wave or hand-solder process.
Cuttable Strip Sourcing Flexibility
The 36,000-position strip is cuttable — you order one reel and break off the exact pin count your BOM calls for. That means a single stock-keeping unit covers multiple line items on the same board, reducing inventory line count. The strip is loaded all positions, so no blank spaces to work around.
