Product details

Board Layout Fit for the 0.100" Pitch Header

The 77311-122-18LF: Through-hole solder termination (contact length - post 0.120") anchors each pin into the plated through-hole, providing stronger mechanical retention than an SMT header would against cable pull or vibration.

Active lifecycle status — no end-of-life pressure on this BERGSTIK header.

Part of the BERGSTIK series from Amphenol ICC (FCI), a broad family of square-pin headers. The base product number 77311 identifies the unshrouded, single-row, through-hole variant with 0.100" pitch and 0.120" post length.

Frequently asked questions

What is the exact pitch of 77311-122-18LF?

The mating pitch is 0.100" (2.54 mm). This is the standard DIP-compatible spacing, so the header fits into a 0.100" pitch female socket or a PCB with matching through-hole pattern.

Is 77311-122-18LF through-hole or SMD?

Through-hole solder termination. The solder post is 0.120" (3.05 mm) long, designed to insert into a plated through-hole and be wave-soldered or hand-soldered.
