Using Plain polyester or Metalized polyester Capacitor in place of polypropylene

[I_think]

I was trying to understand if I can use Plain polyester capacitors in fan regulator circuit instead of polypropylene.

Refrence : regulator type. https://www.indiamart.com/proddetail/fan-regulator-circuit-4705838233.html

If they are rated for 250VAC (or whatever the applied AC voltage is) ...

FVM thanks, when ever I put on thread you mostly answer all.

I am expecting that. Also wondering if it can handle surge. I remember a decade ago when these capacitor regulator swamped the indian market , there were heavy failures. mostly cap blew off. now all of them have stabilized their product with polypropylene. And I rarely see any failure.

Although I am planing to use triac as a switch with ZCD in place of mechanical switch .

Lets see if someone here has more information.
