The post finish is tin (50.0 µinch) for good solder wetting to the board pad. ## Position Count vs the 6- and 8-Position Siblings The 4-position version (20021121-00004C4LF) is the smallest dual-row member in this Minitek127 SMT header family. If the BOM calls for 4 circuits, this is the part; if the layout has room for extra pins for mechanical stability or future expansion, the 6- or 8-position versions drop into the same footprint family.","metaTitle":"20021121-00004C4LF Amphenol ICC Minitek127 1.27mm 4-Pin SMT","metaDescription":"20021121-00004C4LF — Amphenol ICC Minitek127 1.27mm pitch, 4-position dual-row unshrouded SMT header.
