Hi,
Thank you for contacting Intel Community.
You can find the FIT rate for Altera devices in the Reliability Report. Kindly be noted that the FIT rate for devices within the same family with the same process technology will be very similar and can be used for devices not explicitly listed in the Reliability Report.

Hope this help! Let me know if you need more information.
Regards,
Aim
