The 0.050\" row spacing mirrors the pitch, keeping the routing lanes symmetrical on both axes. The tin-plated posts (50 µinch) are solder-compatible with standard reflow profiles. ## Position Count vs. Sibling Options The 4-position variant is the smallest in the dual-row SMT family. The 8-position (20021121-00008T1LF) and 10-position (20021121-00010T1LF) siblings use the same 1.27 mm pitch, gold flash mating finish, and 1 A rating — the only difference is the number of circuits. For a one-time board-to-board link, the flash version is cost-optimized.","metaTitle":"20021121-00004T1LF — Amphenol ICC Minitek127 1.27mm 4-Pin","metaDescription":"Amphenol ICC (FCI) Minitek127 4-position unshrouded SMT header, 1.27mm pitch, gold flash contacts, UL94 V-0.
