Tin Contacts at 80µin — Moderate Duty Cycle
The 647676-3: For applications requiring repeated field-service disconnect, consider a gold-plated sibling — but for fixed harness assemblies or infrequent maintenance, the tin interface delivers reliable contact resistance at a lower cost.
Peer Comparison — 4-1775099-7 vs 647676-3
Key differences: 647676-3 is a 3-position single-row at 3.96mm pitch with 7.5A, while 4-1775099-7 offers 20 positions in dual-row at 4.20mm pitch with 9A and a full 4-wall shroud. The 647676-3 suits low-position-count, space-constrained board-edge connections; the ATX peer fits higher-density power distribution requiring more circuits and a fully shrouded interface.
