50-Position Dual-Row at 1.27mm Pitch
The 20021311-00050T4LF: This is a 50-position, dual-row female socket receptacle from the Minitek127® 1.27mm series by Amphenol ICC (FCI).
Through-Hole Solder with Gold Contact Interface
Termination is through-hole solder, with the contact post length at 0.094" (2.40mm) — enough for standard PCB thickness without protruding past the solder fillet. This dual-plating strategy gives a corrosion-resistant mating interface and a solderable tail.
The part is RoHS compliant.
