The closest sibling is 77311-101-02LF — same 2-position, same pitch, same gold plating and current rating, but with a shorter overall contact length (0.425" vs 0.525") and bulk packaging instead of bag. If your board stack-up needs the longer 0.525" pin for a deeper receptacle, the 77311-103-02LF is the one. The 1-position 77311-101-01LF is a single-pin variant for applications needing only one circuit.
Both are 2-position, single-row headers with the same pitch, plating, and current rating. The main difference is overall contact length: 0.525" on 77311-103-02LF versus 0.425" on 77311-101-02LF. Check your board stack-up and mating receptacle depth to see which pin length fits.
