STM32G491KCU3/6 Differences

I found https://community.st.com/t5/stm32-mcus-products/stm32g491kxu6-don-t-have-exposed-die-pad/m-p/625099#M231656 on differences between STM32G491KCU3 and KCU6. Is junction temperature range the only difference between these parts?

Correct, the last digit, in this case 3 and 6, only indicates the temperature range within which the respective device is guaranteed to function without errors. Apart from the price, there are no other differences.

Hope that answers your question?
