Board-to-Board Fit: 0.100" Pitch and 4 Circuits
The 75915-304LF: The through-hole solder tails — 0.114" (2.90mm) post length — anchor into the PCB and carry the mechanical load from the mating cycle. For a test fixture or a board that gets swapped quarterly, that gold layer buys you decades of reliable contact.
Mating Half and Housing Details
RoHS compliant.
Where This Connector Fits
The 4-circuit single-row layout is a natural fit for low-pin-count signal interconnects — sensor boards, control I/O, or programming headers where you need a reliable separable interface.
