In addition to the adapters, it's possible to replace the entire cable assembly with one with a J1772 plug. This might be preferable to using an adapter if you replace a Tesla with a non-Tesla EV; however, it would be more hassle to install and it would probably be more expensive. Also, if you replace the car far enough into the future, it's conceivable that the Tesla Wall Connector would be on its last legs, or there might be features in newer J1772 EVSEs that you'd want. Thus, replacing the EVSE might make sense in this scenario, although that would likely be even more expensive. You could probably re-use the wiring from the breaker box to the EVSE, though, so installation costs would be low.
Currently, Tesla's J1772 adapter is $95, and one comes with every new Tesla sold, whereas third-party adapters to let non-Teslas charge on a Tesla EVSE cost in the $200-$250 range. Of course, that might change in the future.
Also, be aware that Tesla has recently discontinued its Gen2 Wall Connector in favor of a Gen3 model. There are various discussions on this forum about this shift. In brief, the Gen3 unit has an ~18-foot cable, vs. a choice between ~8-foot (IIRC) and ~24-foot cables for the Gen2; the Gen3 maxes out at 48A, whereas the Gen2 can provide up to 80A (but both can be dialed down below these limits, and often are, to match what's reasonable given your car's and house wiring's capabilities, and all current-production Teslas max out at 48A or lower); and the Gen3 adds new WiFi features. If you prefer the Gen2 features, you may need to scramble to find one; I don't know how much Gen2 stock is left. Given the wide variety of third-party J1772 EVSEs, you can probably find almost any mix of features you want in them, except of course for the Tesla plug and interoperability with Tesla EVSEs (for load sharing, etc).
