Product details

The 77311-129-16LF: The 0.136" (3.46 mm) post length provides adequate through-hole fill for standard 1.6 mm PCBs.

Board-to-Board Fit and Orientation

With an overall contact length of 0.925" (23.50 mm) and a mating pin length of 0.689" (17.50 mm), this header is designed for vertical board-to-board stacking where the mating receptacle sits above the base board.

Within the same 77311 base number and identical plating, the 16-position 77311-129-16LF sits between the 10-position 77311-124-10LF and the 36-position 77311-122-36LF. The 16-position variant is the most common density for control and signal I/O on a single row; the 10-position is a compact option for smaller harnesses, while the 36-position fills a dense signal bus.

Frequently asked questions

What is the closest functional alternative to 77311-129-16LF?

The 77311-124-10LF is a 10-position sibling with the same pitch, plating, and current rating. For a 16-position match, the 77311-118-16LF shares the same circuit count and plating but has a shorter overall contact length (0.450" vs 0.925").

What is the pinout diagram for 77311-129-16LF?

The pinout is a single row of 16 male square pins on 0.100" centers. All positions are loaded. The mating side is gold-plated; the solder tails exit vertically through the PCB.
