Can I replace a Citel BMS90 GDT with a Littelfuse SL1021B090X?

Hi everyone,
I’m working on a circuit that originally uses a Citel BMS90 gas discharge tube as part of the surge protection stage. I’m considering replacing it with a Littelfuse SL1021B090X, but I like to ask if the substitution is acceptable?

Thanks in advance for your help!

Hello @aimanjahari3,

Thank you for your post.

Other than the SL1021B090X having a higher current surge capability they appear to be similar enough to be considered good alternates.
