Product details

Dual-Row SMT Header for Tight Board Stack-Ups

The 20021121-00004T1LF: This is a 4-position, dual-row unshrouded header from the Minitek127 series, on a 1.27 mm pitch — the board footprint is compact enough for dense parallel-board stacking where z-height is tight. 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.

Frequently asked questions

What is the mating connector for 20021121-00004T1LF?

This is an unshrouded male pin header. It mates with a Minitek127 1.27 mm pitch female socket (not listed here). The 4-position dual-row receptacle with the same 1.27 mm pitch and row spacing is the matching half.

What is the closest functional second-source — 20021121-00004T4LF?

The 20021121-00004T4LF is the same 4-position, dual-row SMT header with identical pitch, current, and voltage ratings. The difference is the mating contact finish: 10 µinch gold on the T4LF versus flash gold on the T1LF. If your application needs more mating cycles, the T4LF is the upgrade path.
