The 14-position 77311-101-14LF offers a wider circuit count for denser board-to-board connections, but the 3-position version is the compact choice for low-channel-count interfaces. The 77311-118-03LF is a 3-position sibling with a slightly longer overall contact length of 0.450\" (11.43 mm), which may affect the mated stack height in the same board-to-board application. ## Termination and Mating Details","metaTitle":"77311-101-03LF BERGSTIK® 3-Pin Header, 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) BERGSTIK® unshrouded header, 3 positions, 0.100\" pitch, 3 A per contact, gold mating finish.
