Thank you very much for all your responses and suggestions regarding the OCXO replacement.
To summarize our findings: unfortunately, we have not been able to identify
a suitable replacement for the original OCXO. We contacted Microchip/Vectron,
and it appears that the original part is supplied exclusively to an undisclosed
end customer.
In addition, we were unable to source an OCXO with the required 15 V input
voltage for the REF1200 board. As a result, we have decided to purchase a
new REF1200 board from Bruker (approx. EUR 8.5k) and will attempt to repair
the defective board in the longer term.
Thank you again for your support.
Best regards,
Christoph

The OX-205 is in their catalogue, I would contact them for distributors
Mouser also seem to have them listed but you need to contact them
