Frequently asked questions
What does the 1054302403 mate with?
It mates with the matching Nano-Fit 105430 series receptacle housing and crimp terminals — the latch holder on this header locks into the primary housing latch, and the TPA (Terminal Position Assurance) feature on the housing confirms full terminal seating before the harness ships.
What is the pitch and position count of the 1054302403?
The pitch is 2.50 mm (0.098 inch) and the position count is 3, in a single-row configuration — all three positions are loaded.
What connector style is the 1054302403?
It is a board-to-cable/wire header with a right-angle SMT mounting type and solder termination — the male pin side mounts to the PCB and receives the matching wire-to-board receptacle housing on the mating face.
