The 77311-822-17LF: The through-hole solder tails (0.120" post length) sit in a single row, so the board routing is straightforward: one row of plated through holes at 2.54 mm centers. A standard 0.100" pitch IDC socket or crimp housing with 17 cavities will mate directly — no keying or shroud to clear. The push-pull fastening means the pair stays together through the contact friction alone, so for vibration-prone environments, a locking latch on the receptacle side is worth planning.
The 15.0 µinch gold or GXT™ on the mating face delivers reliable contact through repeated mating — in a field-service application cycled quarterly, that plating thickness supports well over a decade of service at the contact interface.
