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.","metaTitle":"20021121-00050D1LF Amphenol ICC Minitek127 1.27mm 50-Pin","metaDescription":"20021121-00050D1LF Amphenol ICC Minitek127 1.27mm pitch, 50-position, unshrouded SMT header.
