Difference between two types T-series Triacs

Posted on July 13, 2018 at 09:59

I ordered a Triac with type number T1635T-8T for temperature controlling on a hot glue application. 

This was not the same comparing to the fried one I already have on the application with type number T1635T-8I. The difference I found when comparing was: Rate of decrease of commutating on-state current. Can someone please tell me if I still can use the T1635T-8T?
