The 1761606-5: The through-hole termination with 0.102" (2.60 mm) post length suits wave-solder assembly; the tin-plated post finish provides a reliable solder joint.
Comparison with Peer 1318699-3
The 1318699-3 is a 12-position, 4-row header with 0.165" (4.20 mm) pitch and 5 A per contact rating — a higher-current, coarser-pitch alternative. The 1761606-5 offers 14 positions in a denser 2-row layout at 1 A, making it the better fit for signal-density applications where board space is constrained.
