The 1-645955-1 is a Series 2 contact from TE Connectivity, a solder-terminated socket that accepts pin diameters from 0.014" to 0.026" (0.36mm to 0.66mm).
The 1-645955-1 is marked Obsolete by the manufacturer.
No pin-compatible alternative is documented in the same Series 2 family. The 1-645955-1 accepts pin diameters 0.014" to 0.026" and uses a solder termination — any substitute would need to match the 0.052" (1.32mm) mounting hole diameter and overall length of 0.184" (4.67mm).
