The closest functional peer is 20021321-00040T4LF, which is identical in every spec except the packaging suffix — the T4LF variant ships in a different tube format. For a BOM line, either works as a drop-in replacement if the packaging is compatible with your pick-and-place feeder. ## Production Status and Compliance","metaTitle":"20021321-00040D4LF Amphenol ICC (FCI) Minitek127 40-Pin SMT","metaDescription":"20021321-00040D4LF: 1.27 mm pitch, 40-position, dual-row SMT receptacle.
