Frequently asked questions
What is the 0423751247's listed series?
The part is listed under Series KK254, 42375 — a 0.100 inch (2.54 mm) pitch single-row header family used across automotive, general purpose, medical, and telecommunications applications.
What does the 0423751247's board-to-board style mean for my application?
The Board to Board or Cable style designation means this header mates with the matching KK254 IDC receptacle or ribbon-cable socket — it is not a wire-crimp housing but a pin header intended for through-hole board mounting or cable termination via a discrete mating half.
