The Amphenol BERGSTIK® II 86837-142HLF is a 42-position dual-row unshrouded male header on a standard 0.100" (2.54 mm) pitch, designed for board-to-board interconnect applications where a low-profile, through-hole solder connection is required. This is a full-populated header — all 42 positions are loaded with square male pins made from phosphor bronze, with the mating surface finished in 30.0 µin (0.76 µm) gold or Gold, GXT™ for reliable repeated mating. The 0.100" pitch and 0.100" row spacing give a familiar footprint that matches legacy 2.54 mm grid layouts, and the 0.120" (3.05 mm) solder post length suits standard 0.062" PCBs.
Fit and footprint notes
The unshrouded header has no keying or polarization ramp. The insulation height is 0.100" (2.54 mm) and overall contact length is 0.600" (15.24 mm). The 42 positions at 0.100" pitch fit a standard 2.54 mm grid; the dual-row arrangement means 21 pins per row. The through-hole termination requires plated holes on 0.100" centers. The black insulation color is a visual check during board assembly, but carries no electrical function.
