I can give you AESA details but true knowledge is scarce and confidential about new features of Block III. AESA will be able to track 15 targets and engage 4 and might even get PL-15 the Chinese equivalent of Meteor and be able to take down any Indian aircraft very easily. It isn't confirmed if India is even getting Meteor yet.
range detection of 170km for a 3 m2 target and 200km for 5 m2. Su-30MKIs RCS is probably 5m2 or higher so detection will be no challenge not factoring in ECCM of Su-30MKI.

Also, as I said before J-10 is in a different weight class than JF-17 completely and is roughly 1/3 heavier. J-10 is light-medium fighter and JF-17 is very light weight fighter.
