Product details

40 positions on 0.050" pitch — dual-row board-to-board header

The 20021221-00040T4LF is a 40-position, dual-row shrouded header from the Minitek127® 1.27mm series by Amphenol ICC (FCI).

Surface-mount termination and mating fit

No through-holes needed, which frees up routing space on inner layers. The push-pull fastening type and full 4-wall shroud mean the mating receptacle aligns and locks without extra hardware.

No immediate obsolescence risk.

Position count comparison: 30, 40, and 60 positions

The 20021221-00040T4LF sits between the 30-position (20021221-00030T4LF) and 60-position (20021221-00060T4LF) siblings in the same series. If the BOM calls for 30 or 60 circuits, the same header footprint and mating receptacle family apply. No need to re-layout the board for a different series.

Frequently asked questions

What is the recommended mating connector for 20021221-00040T4LF?
