26-Pin Shrouded Header for Board-to-Board Stacking
The 90309-126LF: This is a 26-position, dual-row board-to-board header from the Minitek® series, built for parallel PCB stacking. The 0.079" (2.00 mm) row spacing matches the pitch, keeping the routing density uniform across both axes.
The mating surface is finished with 30.0 µinch (0.76 µm) of GXT™ gold over nickel — a hard gold alloy rated for repeated mating cycles. The solder tails are tin-plated (78.7 µinch / 2.00 µm), which wets reliably in wave-solder or hand-solder processes.
