Illy Resistance x3

Hello I am new, I would like to kindly ask the experts, that is, those who usually do their own repairs of their machine, if the resistance of Francis Francis Francis x3 is compatible with other machines.
I have repaired it many times, always for different problems but last time I made a mistake: after completely disassembling the boiler I noticed that one of the two gaskets on top, where the electrical wires fit was broken and I replaced it temporarily with "Teflon" plumber's tape well it ran like clockwork for 6 months so much so that I had forgotten to buy the gaskets then suddenly it had fireworks and only then opening it I saw that one of the two appendages had gone, charred! Yielding to the wear and tear of the Teflon the electrical parts were no longer insulated.
Now that I unfortunately have to buy myself the whole heating element, I am having trouble finding it and especially at a fair price and was wondering if the one from Pavoni, which is apparently the same, could fit inside my boiler.
Thanking you in advance for any advice I remain in anticipation.
