Product details

0.100" Pitch, 3-Position Unshrouded Header

The 0022122031: The single-row, 3-position layout mates with a matching KK254 receptacle housing, making it a straightforward BOM line for low-circuit-count wire-to-board or board-to-board interconnects.

Gold-Plated Mating Interface for Repeated Cycling

The posts are tin-plated (100.0µin) for reliable solder wetting.

Active lifecycle status — no end-of-life watch for ongoing builds. ROHS3 compliant.

The bulk package feeds hand-assembly or low-volume lines — no reel for automated placement.
