Current and Temperature Ceiling Check
The 77313-127-70LF: The 3 A ceiling is per-contact at 25°C ambient; the actual current you can carry in a harness depends on the derating curve in the product drawing and the number of adjacent circuits carrying full load. The UL94 V-0 thermoplastic housing keeps the connector compliant inside equipment requiring a flame-rated enclosure.
Through-hole solder termination — the 0.105" (2.67 mm) post length fits standard PCBs with enough tail for a reliable solder fillet.
