Product details

50-Pin Dual-Row Footprint at 1.27mm Pitch

The 20021111-00050T4LF: This is a 50-position, dual-row unshrouded pin header from the Minitek127® 1.27mm series by Amphenol ICC (FCI).

1A per Contact — Signal-Duty Current Ceiling

The square male pins are copper alloy with a tin-plated solder post (shows 50 µinch tin on the post). The through-hole termination gives a robust mechanical anchor to the PCB — no worry about SMT pad lift during cable strain.

Temperature Range and Material Choices

The thermoplastic insulation material holds its dimensional stability across that range. Overall contact length is 0.309" (7.86mm) with a mating pin length of 0.120" (3.05mm) and a solder tail of 0.091" (2.30mm).

Frequently asked questions
