The Amphenol 87185-106HLF is a 6-position, single-row BergStik® II unshrouded header on the standard 0.100" (2.54mm) pitch.
The 0.100" (2.54mm) pitch is the classic breadboard-compatible spacing — it matches the vast majority of perfboard, prototyping grids, and standard 0.100" female socket strips. The 6-position count is a common size for a low-channel signal header or a small power tap; confirm your BOM circuit count matches exactly, as this is a single-row unshrouded header with no option to depopulate positions. The 30.0µin (0.76µm) gold plating on the mating surface is a mid-grade finish — it handles moderate mating cycles (typically 100-200 cycles) without fretting corrosion, making it suitable for field-serviceable connections where the header is mated and unmated occasionally. The through-hole solder termination gives a mechanically robust joint on the PCB — the 0.095" (2.41mm) post length is sized for standard 0.062" (1.6mm) boards. The overall contact length of 1.238" (31.45mm) with a 1.043" (26.49mm) mating length means the header stands tall above the board, which is typical for BergStik headers used in board-to-board stacking or wire-to-board applications with a receptacle.
