The 20021321-00040T4LF: It won't fret like tin in a corrosive environment, but for high-cycle duty (500+ mates) you'd want 30µin or thicker.
The sibling 20021321-00040D4LF is electrically and dimensionally identical — same 40 positions, same pitch, same gold plating — but adds a pick-and-place feature on the housing top. If your line uses vacuum pick for SMT placement, the D4LF variant saves a manual handling step. Without that need, the T4LF is the simpler part.
This receptacle mates with a 40-position, 2-row, 1.27mm pitch pin header from the Minitek127 series.
