Product details

Board Fit and Position Loading

The 20021221-00108D4LF: This is an 8-position header from the Minitek127® 1.27mm series, but only 7 positions are loaded with male pins — position 8 is vacant. That vacant position acts as a built-in keying feature, preventing mis-mating with a receptacle that expects a full 8-way pin field. The 1.27mm pitch and 0.050" row spacing set a compact board footprint — roughly half the density of a standard 0.100" header.

Current and Environmental Ratings

The gold mating finish (10µinch) on a copper alloy contact gives good corrosion resistance and stable contact resistance over repeated mating cycles, suitable for board-to-board applications where the connector stays mated for the product life.

Comparing to the Full-Loaded Sibling

The closest functional alternative is 20021221-00008T4LF — identical in pitch, plating, current rating, and SMT footprint, but with all 8 positions loaded. If your mating receptacle has a full 8-way pin field and you do not need the keying from the vacant position, the 00008T4LF is a drop-in replacement. The 6-position variant (20021221-00006T4LF) shares the same specs for lower circuit-count designs.

Frequently asked questions

What is the mating connector for 20021221-00108D4LF?

This is a male pin header from the Minitek127® 1.27mm series. It mates with a Minitek127 receptacle (female socket) of matching pitch, row count, and position count — typically 8 positions, though the vacant position 7 on this header means the mating receptacle should have a corresponding blank or keying feature.

What is the difference between 20021221-00108D4LF and 20021221-00008T4LF?

Both are 8-position, 1.27mm pitch SMT headers from the same series. The -00108D4LF has only 7 positions loaded (position 8 vacant), while the -00008T4LF has all 8 positions loaded. All other specs — pitch, plating, current rating, insulation material — are identical.
