Board-to-Board Receptacle for 1.27 mm Pitch Stacking
The 20021311-00016T4LF: This is a 16-position, dual-row female socket receptacle from the Minitek127® 1.27mm series by Amphenol ICC (FCI). It mates with a matching 1.27 mm pitch pin header to create a board-to-board connection, with a push-pull fastening style that keeps the pair engaged without a locking latch. The 1.27 mm pitch and 0.050" row spacing set a tight board footprint — the dual-row layout packs 16 circuits into a narrow body, suitable for dense PCB layouts in telecom line cards or industrial control modules.
Mating contacts are gold-plated at 10.0 µinch (0.25 µm) over phosphor bronze — this is a moderate-duty finish for applications with a few hundred mating cycles, typical for factory-floor sensor interfaces or telecom backplane cards that are swapped during maintenance.
