    That's better. Next check that the turn on/turn off delay times in the datasheet are no greater than those of the original. Same for the total gate charge (Qg). This is for compatibility with the programmed dead time and gate drive. If those specifications are met you can be reasonably confident that it's suitable. You could go into more detail (e.g. compare the Vds vs Ids), but it's not really worth it for a cheap product and you would need to identify more components in the circuit to be sure.

    Edit: Also, in order of preference for brands I would go with for IGBTs are Infineon, IR, ST / ON Semi & others. But this is pretty subjective.

    [P.S. I'm trying to demonstrate how to choose - not just give you a link. For reference, I've found some in England for around 3 CHF.]
