The 2178710-6: The fork-style tin-plated contacts mate with matching pin headers in the same series, and the push-pull fastening keeps the pair engaged without a secondary latch. Rated 100 VDC and operating from -30°C to 85°C, this receptacle suits general-purpose and telecom signal interconnects where the board environment stays dry and the mating cycle count is moderate — tin-on-tin contacts are cost-effective but wear faster than gold under repeated disconnect.
Sourcing an Obsolete Part

The kinked-pin solder tails (0.122" / 3.10mm post length) fit standard 1.6mm-thick PCBs and provide mechanical retention during wave soldering. The black PBT housing carries a 0.157" (4.00mm) insulation height, which sets the mated stack height when paired with a matching header.
