All APs can be used for any regulatory domain; assuming they were purchaesd as an "AP" model and not "IAP". IAP models have the country designation; so if you have an IAP-105-US, then correct, it will not work on a non-US controller. However, if you have an AP-105 (non IAP model), it will work fine on any controller as campus AP models do not have a country designation.
The 105s are end of sale, so you'll need to buy one second hand if you really need a 105 vs newer models.
