novis needs help please

So I have a question but bear with me as I wont know the lingo. So the other day my SR sun tour chain set shattered so I am looking to replace it and was thinking about can I replace a SR sun tour CW-XCC-T202-PB Chain set, 22 32 42T with a SR Sun tour CW-XCC-T208-PB Chain set. 28/38/48T x 170mm, or would that mean I would have to replace or parts? Sorry if it is a stupid question

The number of rings has a lot to do with the length of chain and type of derailleurs required. The width of the chain depends on the number cogs on the freewheel...

External width[edit]

The external width matters for derailleur-equipped bikes because rear cogs are spaced close enough together such that a chain that's too wide will rub on adjacent cogs.

So, the width of chain required basically depends on the number of cogs (speeds) in back, since clusters with more speeds have their cogs spaced closer together.

In general, drivetrains up to and including 8 speeds can use the same speed chain. The packaging/marketing chains often don't mention that they work with 5, 6, 7, or 8-speed bikes -- but if it mentions compatibility with any of these speeds, then it is compatible with all. The pin width of these chains is usually 7.1 or 7.2mm.

9-speed drivetrains use chains up to 6.8mm wide. These are typically explicitly marketed as 9-speed chains.

10-speed drivetrains use chains up to 6.2mm or so wide. Again, these are marketed as 10-speed chains.

It is usually possible to use a narrower chain on a fewer-speeds drivetrain, but beware of narrow 9-speed and above chains with old chainsets as the chain may drop between the rings when changing down to the inner ring. There's no significant benefit to doing so though since 9- and 10-speed chains are more expensive.
