Dredging thru the archives of my memory, I recall the 50 um of gold as a
minimum requirement for the RJ - Registered Jack spec from the old Bell labs
for reliability. It might now be enshined in an IPC spec, or still just a
telecom detail. And there might be some updated info, since those memory bits
are quite old. I'll guess your socket gets more use than the estimated use
for phone jacks.

We’re running into life issues on load boards where the Johnstech socket
wears through a layer of 50 um hard electroplated gold. Does anyone have
experience with Rhodium electroplating as a long life replacement for gold?
The gold is specified for a hardness of 160-200 Knoop and Rhodium is 900-1000
Knoop.
