The 77311-124-02LF: The 0.266" (6.75mm) mating pin length gives enough reach for standard receptacles without bottoming out.
If your board stack-up has a tight z-height budget, the 127 variant saves 0.015" of through-hole protrusion. For a 10-position version, 77311-124-10LF keeps the same pitch and plating but adds eight more circuits in the same single row.
Both are 2-position, single-row, gold-plated BERGSTIK® headers with the same pitch and current rating. The difference is overall contact length: 77311-124-02LF measures 0.480" (12.19mm), while 77311-127-02LF is 0.465" (11.81mm). Choose based on your board thickness and receptacle depth.
