Within the same 77311-101-xxLF family, the 2-position variant (77311-101-02LF) shares identical pitch, plating, current rating, and overall length. The 14-position sibling (77311-101-14LF) also matches all other specs but adds 10 more circuits on the same single-row 2.54mm pitch. No functional substitution needed – just a BOM position count decision.
The 77311-101-02LF is the same BERGSTIK® header with identical pitch, plating, and current rating, but only 2 positions. If your BOM requires 4 positions, the 77311-101-04LF is the correct part – no direct second-source exists.
