Cartouche de blocage SR Suntour SF14-XCR-32 RL 27,5 FUN015-50

I have a fork with a Suntour FUN 043-21 cartridge which is not working anymore.
Unfortunately, it is impossible to find the same reference of cartridge anywhere.
The size of the wheel is 26'' and it is a remote lock. The bike is a TREK 4900 and the fork SR Suntour XCR-RL
Which model of cartridge do you advise me to buy to replace it ?
