Board Layout Fit: Pitch, Positions, and Footprint
The 10077239-116TLF: All positions are loaded, so the BOM count matches the pin count exactly. The through-hole press-fit termination means the pins are inserted into plated holes and mechanically retained without solder — a clean, rework-friendly assembly for backplanes or high-reliability stacks. The 0.190" (4.83mm) post length gives enough tail for a typical 1.6mm board thickness plus a wave-solder step if needed.
Contact Rating and Mating Cycle Life
That gold thickness is the standard for 500+ mating cycles — in a field-service board where the connector is swapped quarterly, you get well over a century of service at the contact interface before fretting becomes a concern. The tin-plated post is the solder-side finish; the gold-on-gold mating interface is what carries the signal. Temperature range is -65°C to 130°C, covering most industrial and telecom environments without derating.
