Board-Stacking Fit: Pitch, Positions, and Plating
The 20021311-00030T4LF: The 1.27mm pitch and 30 positions set the board footprint — this receptacle mates with a matching Minitek127 pin header to create a board-to-board stack. The post finish is tin, which solders cleanly into the plated through-hole. The push-pull fastening means the connector pair stays engaged by friction and contact normal force — no locking latch. For a board-stacking application where the assembly is enclosed and static, this is adequate; for high-vibration environments, consider a locking header option in the same series.
