Product details

19-Position Single-Row Header for Board-to-Board Stacking

The 77311-122-19LF is a 19-position, single-row, unshrouded male header from the Amphenol ICC (FCI) BERGSTIK series.

Pitch and Footprint Fit for Legacy Designs

Compared to a 20-position sibling in the same BERGSTIK family, the 19-position variant saves one board trace and one solder joint, which can matter in dense routing or when a specific I/O count is needed without extra unused pins.

It is available for order through independent distribution channels; quantities are sourced per RFQ, and current pricing is confirmed at quote time. No official replacement or cross-reference has been issued by the manufacturer.

Compliance and Material Notes

The contact material is phosphor bronze, a standard spring alloy that resists stress relaxation under repeated deflection. Operating temperature range spans -65°C to 125°C, covering automotive underhood and industrial cabinet environments.
