What characteristics should I look to know if a diode is equivalent?

Good morning YoReparo¡¡ family My query today is as follows: What characteristics or data should I look / compare to know if one diode is equivalent to another? that is, when I have in my hands the specification sheet of a given diode, what should I look for to find another equivalent (assuming, as in many cases, that a list of equivalences does not appear on the sheet). Thank you and good start to the week!

Follow the link below, there you will not only find equivalences but also the values to consider

Hello, Tension (direct and Reverse), Intention, Power, Switching speed. They are the main data. Unless we do not talk about common diodes, for example Varicap, there things change. Regards

Great, thank you very much! And what margin is there in any of those values?
I explain myself, a few days ago I was told that Diode SB3100 is comatible to SR2A0 but the intensity for example is not the same. I was trying to attach a screenshot of the sheets comparing but not let me, I write:
For the SB3100
Direct Voltage: 850mV
Reverse Voltage: 100V
Intensity: 3A
Power: 3.6W
Switching speed: 8.3ms
I'm not even sure to extract the information from the data sheet well, in case anyone can check it. Then I put the SR2A0

For SR2A0
Direct Voltage: 850mV
Reverse Voltage: 100V
Intensity: 2A
Power:
Switching speed: 8.3ms
The parameters that I most doubt extract are the power and switching speed. But the intensity is not the same, how do I know if they are really compatible?

hello, in this case the SR2A0 can be replaced by the SB3100 but on the contrary it CANNOT. Since the intention is less, I don't know if I explain myself if the voltage intention intensity parameters are equal or greater and the switching speed is the same or "lower" serves as a replacement.
