-10 family will not transition to this production-certified variant because of its higher bypass ratio compared to the AL-31 family which entails its having less consistent power output during flight at high altitudes or during vigorous manoeuvres. The J-10 series is increasing the electronics content of every successive iteration from the J-10 to 10A to 10B to 10C, so it's imperative that the engine does suffer unpredictable drops in power output as the electronics cannot function without a consistent power supply. The WS-10B, on the other hand, does have decent prospects of future wide-scale adoption on the J-10 series. The Sino-Flanker series can mount the production-certified WS-10 just fine because of their twin-engine design which means both engines supply power to the electronics basically guaranteeing that, even if the WS-10s suffer power output drops during high-G manoeuvres, there would still be enough power from the two engines for the electronics.
