Replacement Triton cartridge - unknown part number

I have a Triton Aquasensation Mixer Shower from 1996. The cartridge unit has broken. The cartridge assembly is listed in the User Guide as part no. 83303820 but I cannot find this anywhere. The 83304950 looks very similar. Do you know if it is compatible? Thanks.

If your shower looks like this and has the same dial etc then this is correct.
