JF17 is supposed to be a plug and play fighter jet, so no reason why an export model could not be the same as Pakistani version or even better. It all depends on the buyer country's negotiating position for sub-components. No reason why a Saudi version of JF17 could not have French AESA radar, avionics and missiles.
I am not aware of any sub-component developed by Pakistan itself, exporting which could compromise the Pakistani version of JF17. Almost every component is being imported and another country could get clearance for the same equipment.
In aircraft design terms, there is no such thing as plug and play. Every component that you choose has to be integrated at some level. Main components like radar, ECM etc. require major work while some require only minor changes. Much of the JF-17 avionics are now being produced at Kamra, and this includes Weapons Mission Management Computer (WMMC), EMMC, ISR & Light Warning System (LWS), INS, SHUD, SMS & ILS with complete transfer of technology from CATIC. CATIC transferred this tech at high cost as they were not ready to part with it. Some of sub-systems are of western origin and are also co-produced at Kamra and this includes radio, RWR, radar altimeter etc. There are also some other Chinese (non-CATIC systems) that are being produced locally such as radar, IFF transponder, IFF interrogator etc. Some systems were designed and developed locally, such as complete production of Smart Heading & Reference System (SHARS) with the help of Navtech of Singapore. Avionics Activation Panel (AAP), Up Front Control Panel (UFCP), Audio Control Box (ACB), Backup Acquisition Computer (BAC) and Smart Multi-Functional Coloured Display (SMFCD) are also indigenously designed, developed and qualified. ´The Digital Video Recorder was designed locally as well by Strategic Task Group (STS) & there are also other locally developed sub-systems such as ACMI & Chaff and Flare Dispenser and R&S Radio from AWC on board.
