R-13, R-503 or R-508B

Add more static pressure estimated 20psi + to equal R-23 performance.

It is mostly one option to get and that is the 508B.
I have used that one on a couple of hundreds ultra low temperature units over some Years and it works very well. My experience is to charge to the same static pressure as the R23. To find R503 in Europe anyway was over for qiute some Years ago. This azeotrope mix og R23 and R13 was banned due to the ozone killing R13 part.
It is also a more seldom type than the Du Pont
R 503B It is the ICI type 508A which are commonly used in Japan under licence of ICI
They both have almost the same azeotrope mix of R23/116. It is named TP5R3. May be that one is better known in your area? :D
Good luck anyway
