The 77311-101-03LF: Compared to the 2-position 77311-101-02LF, this 3-position variant adds one circuit for applications needing a third signal or power line while sharing the same pitch, plating, and overall contact length of 0.425" (10.80 mm). 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.
Amphenol ICC (FCI) BERGSTIK® series, 77311-101-03LF, unshrouded male pin header, 3 positions, single row, 0.100" (2.54 mm) pitch, through hole solder termination, gold or GXT™ mating finish, 3 A per contact, UL94 V-0.

Frequently asked questions
What is the closest functional second-source for 77311-101-03LF?
The 77311-101-02LF is the closest functional sibling — same series, pitch, plating, and overall contact length, but with 2 positions instead of 3. For a 3-position alternative with a slightly longer contact length, consider the 77311-118-03LF.
