BERGSTIK breakaway header, 54 positions, unshrouded
The 77313-122-54LF is the 54-position member of Amphenol ICC (FCI)'s BERGSTIK breakaway header line, designed for board-to-board or cable applications. It carries two rows of square male pins on a 0.100" (2.54mm) pitch with a 0.100" row spacing, rated 3A per contact, and uses a gold or GXT mating finish with 30.0µin (0.76µm) thickness.
Position count and footprint across the series
The 54-position 77313-122-54LF sits at the high end of the BERGSTIK dual-row breakaway range — the 0.100" pitch and 0.100" row spacing are shared across the series, so the board footprint is identical regardless of position count.
