If the BOM calls for 44 positions, the 40-position part leaves four unused pads; the 50-position part adds six extra contacts that may need to be left unpopulated or tied off. Stick with the exact count to keep the board layout clean.","metaTitle":"20021311-00044T4LF Amphenol ICC Minitek127 1.27mm 44-Pin","metaDescription":"Amphenol ICC Minitek127 1.27mm pitch, 44-position dual-row through-hole receptacle.
