Product details

Board Footprint and Pin Count

The 77313-118-50LF: This is the standard 0.025" square pin pattern that mates with IDC sockets, crimp receptacles, and BergStik-compatible female headers. That gold thickness supports repeated mating — in a test-lab or field-service board where the connector sees quarterly disconnect, the contact interface stays below the fretting threshold for decades.

Through-Hole Solder Termination Details

The post length is 0.120" (3.05mm) — enough to clear a 0.062" board and leave a visible solder fillet on the bottom side. Unshrouded push-pull fastening — no latch, no keying.

Frequently asked questions

What is the difference between 77313-118-50LF and 77313-118-26LF?

The only difference is the number of positions: 50 vs 26. Both are active, 2-row, 2.54mm pitch, unshrouded headers with gold mating finish and tin post finish. The 50-position variant uses the same 0.450" overall contact length and 0.120" post length.
