Product details

Board-to-Board Fit: Pitch, Positions, and Stack Height

The 20021221-00020T1LF: Push-pull fastening means no tool is needed to engage or separate the pair.

Ratings and Operating Range

The 1 A ceiling is typical for a 1.27 mm pitch signal connector — the narrow contact beam and small solder tail limit continuous current before temperature rise becomes a concern. The tin-plated solder tails are standard for SMT assembly and wet well with lead-free solder paste.

The insulation color is black, which is the standard for the Minitek127 series.

Frequently asked questions

What is the closest pin-compatible alternative to 20021221-00020T1LF?

No official pin-compatible alternative is listed by the manufacturer. The 20021221 base number covers the Minitek127 SMT header family; other position counts in the same series share the same pitch and contact layout but differ in circuit count.

What is the pitch and mounting type of 20021221-00020T1LF?

The pitch is 1.27 mm (0.050") on both the mating interface and the row spacing. The mounting type is Surface Mount (SMT).
