Component compatibility for repair

Kikerumbo · Oct 17, 2023

Hi everyone.

I have a quick one (I hope). I have to swap two IGBTs with part number IRG4PC50U but the warehouse sent me IRG4PC50W.

Are these compatible? Or should I reorder the IRG4PC50U?

Thanks!

P.S: Here I leave the links for the data sheets:

Differences are noted in the datasheet. I cannot determine if the differences will impact your application.

They are compatible in function but both are obsolete, so the substitution (mainly) means the temperature rise may be up to 15% higher with Vce(sat) higher limits.

If you have thermal problems these will be better, rated at much higher currents.

Rated for much higher currents but, may heat up significantly vs the specified part because of the slow switching speed. It really depends on the operating frequency.
