MP28164 vs MPQ28164

Hello,

is there any difference between these types DCDC?

I received an answer from distro that the operating temperature is the difference, but I see in the datasheets that it is the same.

Hello,
Welcome to the forum.
Both the parts are same in terms of characteristics. The only difference is that the MPxxxx family is consumer grade while the MPQxxxx is the industrial grade.
Let me know if you have any further questions.
