Frequently asked questions
What series is the 20021121-00018D4LF from and what is its pitch?
The 20021121-00018D4LF is the 18-position member of the FCI Minitek127® 1.27mm board-to-board header series, with a 0.050-inch (1.27 mm) dual-row pitch.
What does the 20021121-00018D4LF mate with?
It mates with the matching Minitek127® 1.27mm dual-row female receptacle in the corresponding 18-circuit count — confirm the receptacle's mounting orientation (SMT or through-hole) and polarization features before specifying, as the header is unshrouded with no built-in keying chamfer.
