Can I buy a single replacement for my lost AirPod?

Hi Apple Community,

I recently lost my left AirPod (3rd Generation). The model number is A2565 (confirmed from the box). I tried using the “Find My” app, but I couldn’t locate it—possibly because it is out of range or out of battery.

I still have the right earbud and the charging case.

Can I buy a single replacement for the left earbud (A2565), and will it work if paired with my existing case and right AirPod (A2564)?

Serial Number (from box): LJ2*****R9

Thanks for your help!
