50-Position SMT Header in the Minitek127 Series
The 20021121-00050D1LF: It's a surface-mount board-to-board interconnect — the 1.27mm pitch and 0.050" row spacing give you a dense footprint for parallel PCB stacking. Mating contacts are gold flash over copper alloy — suitable for low-cycle mating where corrosion resistance matters more than wear life. The solder posts are tin-plated at 50 µinch for reliable solder joint formation.
Board Fit and SMT Assembly Notes
Unshrouded header with push-pull fastening — mates with a matching Minitek127 receptacle or socket strip. Packaged in tube with pick-and-place features for automated SMT assembly. All 50 positions are loaded. The 1.27mm pitch and 50 positions set the board footprint density — trace routing between pads is tight.
No official pin-compatible replacement or successor listed. The base product number is 20021121.
