Could I use these to substitute?

Arrow.com lists "byp101" as a 1000V 15A 40W 80ns part from Infineon Technologies AG, and 'obsolete', with no price or availability listed.
It would be worth checking around the circuit to confirm polarity before installing it, though -- if you can get one.

Something quirky about that file PRR !

You need to go to your device supplier website and do a parametric search for something similar as an alternative, and then inspect the two datasheets to see if the alternative is acceptable.

What specs have I to check:
Forward current?
Repetitive peak reverse voltage?
Reverse recovery time?
Power dissipation?
TIA
Why? The device has cathode and anode clearly marked, as does the datasheet.
Kay, yep, sorry -- didn't notice that!😱
Maybe my eyesight is worse than I thought!

The STPSC15H12 is a schottky diode - it has substantial junction capacitance (in lieu of a reverse recovery effect). Unless you know the application, then that may not be a good replacement.
Are you able to buy diodes from an on-line supplier? Is the STPSC15H12 the only part available?

On the chance that DigiKey isn't out of the question for you, try cut/pasting below into you favorite browser. They show 10 p/n's that are 1200V, 15A, TO-220, and In Stock, ranging from $1.33 to $13.99 USD, including some SiC Schottky's and even a 'FRED'. One of those ought to be a good fit.

Wow. Seeing it makes me wonder if it'll work, but it might save you a minute or two.
edit: Oh, good -- the website made a reasonable-looking thing out of it.

Several howlers already, and the thread is only up to post #18. Please proceed, it is most delightful.
