Hello,
Please see the qualification report for the part S29GL01GS for the FIT rate. It is available at: https://www.cypress.com/file/502411/download , refer page 6. Please give us some more time to provide you the thermal parameters to calculate junction temperature.
Thanks and Regards,
Sudheesh

Bushra-san,
Thank you for your support.
What is the confidence level?
Is it 99% (α = 0.01)?

Bushra-san,
For example, in the application note below, 95% CL is used to calculate SER.
(it is SER calculation, so it may not be a suitable example)

As an example of another company, TI has the following materials.
http://www.ti.com/lit/an/spraby3/spraby3.pdf?&ts=1589935859658
(this document states that CL = 60%.)
Did you use this factor to calculate the FIT for this device?
Thanks,
Tetsuo
