The tin plating (100.0 µ\" on the mating side) suits low-cycle, low-vibration environments. The 0.100\" pitch and 0.100\" row spacing place the 44 pins on a standard 0.100\" x 0.100\" grid — the same footprint used by DIP sockets, ribbon-cable headers, and prototyping boards. The overall contact length is 0.470\" (11.94 mm), with a mating pin length of 0.250\" (6.35 mm) and a solder tail of 0.120\" (3.05 mm).","metaTitle":"FCI 86503-444HLF BERGSTIK II Header, 44 Pos, 5A","metaDescription":"FCI BERGSTIK II 86503-444HLF unshrouded header, 44 positions, 0.100\" pitch, 5A, tin plating, UL94 V-0.
