Is this Genuine Hitachi IGBT or generic part, any ideas welcome.

Hello,
Had a look at another thread regarding looking for older genuine Hitachi transistors.

I'm replacing two Mitsubishi IGBT on board and decided on ones for sale on ebay, but then got cold feet about how good they are or not.

I then reordered from a company which advertised these as Hitachi parts.

I am not convinced that they are genuine Hitachi, but there is much conjecture out there as to identifying the genuine semiconductors etc. I had expected it to have the Hitachi logo on it, although they have merged with Mitsubishi now too.

I don't want to go to all the bother of installing these only for them to subsequently fail.

Any thoughts or ideas would be appreciated.

They look like pulls with welded on new leads

Fakes are a minefield.
I only buy from reputable sources.
However, if they are obsolete then maybe a test jig to test SOA on them ?
A heatsink and a simple driver circuit would tell you if they are up to the job before yo urisk them in your kit.
