[ARC5] Best Option for Digital Crystal Replacements?

[MICHAEL ST ANGELO]

I was thinking of getting some of the Epson chips but Digikey shows them out of stock:

Hopefully this is a temporary supply chain issue.

I bought a 1 MHZ oscillator module and used it to replace the calibration oscillator in an SG-297, and that worked just great, but I need some specific frequencies for sets like the R-361, SCR-522 and ARC-3.
