The unshrouded design and push-pull fastening let you break the header to a shorter length if needed — it's a breakaway style. The insulation height is 0.098" (2.50mm), which leaves clearance under the mated receptacle for adjacent components.
The black insulator and square 0.324" (8.23mm) mating pin length are standard for KK254 receptacles. The 15µinch gold mating finish and V-0 housing support the medical and telecom reliability requirements.
The part is active and available to quote. No stock-holding claim is made — each order is sourced through our independent distribution network.
The pitch is 0.100" (2.54mm), the standard spacing for KK254 series headers and matching receptacles.
This header mates with KK254 series crimp receptacles (e.g., 002228 series housings with 002228 terminals) and IDC sockets that accept 0.100" pitch ribbon cable. The unshrouded design allows any compatible KK254 receptacle to mate.
