Information gathering for cirsa slots

[Laynord]

Hello everyone

I work in a casino in france and we have some old machines ( by my standards )
we have 3 machines from cirsa that currently have coin comparator issues

They originall were using cc-62's 
We figured the mc-62's were a newer replacement for them struggled a bit making then work tho cause wire was too short so needed to rig a longer one.

My main question was
What is the difference between all the coin comparators and are they interchangeable as long as they have the same voltage
Like could we use the mc-40's we have buckets of to repair them ?

Is there a physical way to distinguish the 2 without the nameplate because they seem to share a PCB 257-000151 ver .1 or .0 or smth like that
Thanks for any info you could give me


PS : my mentor told me they are cirsa but i guess it's unidesa or did they get bought idk still a youngling in all this after 2 years here
