During this time period the Altima shared quite a few parts with the Pathys. For instance, I have a replacement light switch on my steering column that came out of an Altima. So if you take time to check, you may find they are the same part. Altima parts are cheaper in most cases.
Here is an Altima listing on Ebay:

So if the part is visually identical, it is likely the same part. The part number changes because the Altima has a different ID in the Nissan system than the Pathfinder.
It will probably also save money at the wrecking yard if you ask for an Altima part.
