Board-to-Board Fit: 24 Positions at 1.27mm Pitch
The 20021321-00024T4LF: This is a 24-position, dual-row surface-mount receptacle on 0.050" (1.27mm) pitch — the board footprint matches the Minitek127 header family, and the 1.27mm row spacing aligns with standard mezzanine stack heights. The 24 circuits suit mid-density board-to-board interconnects in telecom, industrial control, and general-purpose equipment where routing density matters more than per-contact current.
Position Count Options Along the Same Footprint
The 20021321 base number covers a range of position counts on the same 1.27mm dual-row grid. The 24-position version here sits between the 22-position (20021321-00022T4LF) and the 26-position (20021321-00026T4LF), all sharing the same pitch, row spacing, contact material, and gold plating. If your BOM calls for 22 or 26 circuits, the board layout must adjust the length of the footprint; the contact and housing design is identical.
