Can different Apple TV remotes be used interchangeably?

Yes, different Apple TV remotes can often be used interchangeably. The Siri Remote, also known as the Apple TV Remote in regions without Siri support, notably the second generation (with the touch surface) and first generation (with the clickpad), is compatible with the 4th generation Apple TV (HD) and later models, including the Apple TV 4K editions. Although their design and functionality may vary slightly between versions—such as the addition of a dedicated power button and a redesigned navigation interface in the newer iteration—the essential features remain consistent, allowing for straightforward user experience across different devices. It's important to note that these remotes might not be compatible with much older generations of Apple TV, such as the 2nd and 3rd generations, which relied on an earlier version of the Apple Remote, a simpler aluminum or white plastic infrared remote.
