Board-to-Board Stacking Fit: Pitch, Positions, and Footprint
The 20021321-00016T4LF: This is a 16-position, dual-row receptacle on 1.27 mm pitch — the board footprint matches the Minitek127 header series. For a build-to-print cable assembly, the board-to-board gap is determined by the header's own height — confirm the header part number to verify the total stack. Surface-mount termination means the part is reflow-soldered. The tin-plated posts with 100 µinch thickness are the solder-tail finish — compatible with standard SAC305 or lead-free reflow profiles.
Contact Interface and Mating Cycle Expectation
The mating surface is gold over phosphor bronze, 10 µinch thick.
