Board-to-Board Receptacle for 1.27mm Pitch Stacking
The 20021311-00026T4LF: This is a 26-position female socket header from the Minitek127® 1.27mm series, designed as a board-to-board receptacle.
The 26-position variant sits between the 24-position (20021311-00024T4LF) and 30-position (20021311-00030T4LF) siblings in the same Minitek127® family. The 24- or 30-position versions are not pin-compatible substitutes — the footprint length changes with position count.
It is RoHS compliant, meeting the material restriction directive for EU and global equipment.
The 0.050" pitch drives the board routing density — you'll need a PCB layout that accommodates the dual-row footprint with 0.050" row spacing. The through-hole solder tails (0.094" post length) are compatible with standard wave-solder processes.
