If your salt cell needs to be replaced, you probably have a problem with low chlorine, but if your chlorine level is a problem then the cell is only one of several possible issues, notably including excessive chlorine demand. Essentially, you have either a system problem or a water problem.
System problems will generally reveal themselves with error messages or warning lights on the control module. The typical indications of the cell needing replacement will be one or both of the following: Low Salt warnings that are present with correct salinity and Check/Clean Cell warnings that display when the cell is verifiably clean.
If you are referring to buying the same brand, there’s no question that the original OEM salt cell is exactly what your system was designed to use. However, commonly there are aftermarket replacement cells available which fit into place and operate quite satisfactorily. It is your prerogative to employ one of these aftermarket replacements if you are satisfied with the specifications, price warranty, and reported compatibility.
If you were asking about buying the same capacity cell, then OEM or aftermarket alike, you need to first determine whether your control or power module can accommodate a different size. Assuming you can change sizes, a larger cell is virtually always a good choice. However, in downsizing, make sure the smaller cell is still sufficiently large to maintain 1.5-2 times sizing of the cell relative to the pool’s volume.
