40 positions at 1.27 mm pitch
The 20021121-10040C1LF is the 40-position member of Amphenol ICC (FCI)'s Minitek127® 1.27mm board-to-board header line. Rated 1 A per contact at 125 VAC, with gold-plated mating contacts and tin-plated solder tails. The 0.050" (1.27 mm) pitch and dual-row layout suit dense board-to-board stacking where the current per circuit stays under 1 A.
Minitek127 series footprint
The 1.27 mm pitch and 0.050" (1.27 mm) row spacing are shared across the Minitek127® series — the 40-position 20021121-10040C1LF uses the same board footprint as other position counts in the family, so the layout scales with circuit count without a pitch change.
