The 9-1437514-0: This HOLTITE receptacle accepts round pins from 0.016" to 0.021" diameter and square pins up to 0.011" x 0.018". If your pin is 0.018" round, it falls right in the middle of the range — no fit issue. The beryllium copper contact body gives the socket spring memory over repeated pin insertions, so the retention force stays consistent across the full pin diameter range.
Press-fit termination — no solder, no reflow
The mounting hole diameter is 0.041" (1.04 mm), and the board thickness is 0.030" (0.76 mm). Because there is no tail, the overall length is just 0.094" (2.39 mm) — the socket sits flush with the board surface, saving z-height in tight enclosures.
Lifecycle and sourcing — active, no direct replacement
RoHS compliant.
