I have checked the tool as per the details below, but I’m unable to find the model FSP065-P24-B12 B series. Could you please advise on this? We need to identify a compatible alternative for Fortigate 121G.
Hello nassma.ahmed and welcome to the DigiKey Techforum.
If you are looking for the FSP065-P24-B12, I do not see that we carry the B-Series, but I do see that we have FSP065-P24-A12 from the A-Series. This does appear to have the same dimensions and specifications. The only differences I saw was that the B series manufacturer page mentions "EMI Class B emission for both Class-I (with PE) & Class-II (without PE) application.
If you are looking for an alternative for the FortiGate 121G, I do not see that DigiKey carries firewalls.
I need Power Supply to be compatible with FortiGate 121G, so can you advise if the FSP065-P24-A12 A series is compatible with the FortiGate 121G?
Hello nassma.ahmed,
We do not carry the FortiGate 121G, so I do not know what would be compatible. What are your power requirements for the FortiGate 121G?
The FSP065-P24-A12 power supply is 4.00” X 2.00”, will accept an input voltage from 90~264VAC, and the output will be 12VDC @ 5.4A max.
Thank you @David_1768,
I did see the FSP065-P24-B12 B on the FSP pages. Unfortunately, it is not currently (12 Nov 2025) offered by DigiKey. Interestingly, I don’t see it listed with DK competitors.
Cordially,
Aaron
