A ferrite ring with maybe ten loops (both send and return) will be a pretty good common mode choke i.e. any higher frequency AC noise that occurs on both wires will not easily pass through: -
As you can see in the above attenuation graph, common-mode signals will get much more heavily attenuated than differential noise.
That's the back story to what I believe you have previously used.
The device you propose is a different kettle of fish - it is a single coil and realistically it falls into the category of a ferrite bead. It does nothing to change the common mode signals associated with your power feed because it is a single series device that acts to block HF stuff on one wire only. It's probably not going to be a great deal of use either because it's attenuation impedance at (say) 1 MHz is a few ohms, maybe 10 ohms maximum.
It isn't a common mode choke and it isn't really useful for "blocking" until maybe 10 MHz - see the graphs in the data sheet.
So basically there's no comparison and no great advice to be given - the two devices do different things BUT if the combination of common-mode and differential noise with no protection causes problems then adding this ferrite bead may be enough but it's difficult to tell.
Of course you can buy PCB fittable CM chokes so maybe I'd consider that as the best option.
