Product details

40 pins, 0.100" pitch – the BERGSTIK® footprint

The 861400402YO2LF: The 40 positions are fully loaded, so every pin is present – no breakaway gaps to manage in the BOM. For repeated field-service disconnect or corrosive atmospheres, a thicker gold option in the same series would extend contact life.

3 A per contact, 1000 V – the power path

The 1000 V rating is the dielectric withstand between adjacent circuits – useful in industrial panels where the bus voltage is 480 VAC or lower. The copper alloy pins with gold/GXT™ mating surface keep contact resistance stable across this thermal swing.

The base product number 861400402 covers the unplated variant; the YO2LF suffix designates the gold/GXT™ plating and bulk packaging.

Frequently asked questions

What is the closest pin-compatible alternative in the BERGSTIK® series?

Any 40-position, dual-row, 0.100" pitch unshrouded header with the same tail length (0.118" post) and overall contact length (0.496") from the BERGSTIK® series is a form-fit-function cross. The base product number 861400402 identifies the unplated version; the YO2LF suffix specifies gold/GXT™ plating. Verify the plating thickness and tail length against your application before substituting.
