Board-to-Board Stacking with a 27-Position Single Row
The 77311-802-27LF: This BERGSTIK® header is a board-to-board interconnect, meaning it mates with a receptacle on a second PCB to create a parallel stack. The 27 positions in a single row are unusual — most single-row headers stop at 20 or 25 positions, so this count targets a specific BOM position that needs an odd pin count without a second row.
Sizing the Footprint and Mating Height
All 27 positions are loaded — no optional or skipped pins.
Thermal and Environmental Range
The UL94 V-0 thermoplastic housing limits flame spread in equipment that must pass a flammability test.
