Hello athirahshahril018,

Welcome to the DigiKey TechForum.

The closest option I found to this part, is part number 495-4668-ND.

Has the same shape, and sparkover voltage (72-108V). The impulse sparkover voltage is a little lower (<500 vs. <560V).

Please check the datasheet to verify compatibility to your application.

However, the 495-4668-ND dimensions are too short compared to the CITEL BMS90 unit. This prevents it from being installed properly into the WAGO terminal block. Could you recommend an SPD same like BMS90 that is suitable for installation with the WAGO terminal block?
