You can buy it from here : https://www.digikey.com/en/products/detail/njr-corporation-njrc/NJM4580D/673772

 

and from other stores, findchips.com search : NJM4580D Stock and Price by Distributor

 

These would probably be compatible (not sure, not thoroughly reviewed specs), but they need higher minimum voltages (4580 seems to work from +/- 2v , 2068 needs at least +/- 3v and 5532 at least +/- 4v - your 4580 may run at 5v (+/- 2.5v) in which case the ones below may not work :

NJM2068D NJR Corporation/NJRC | Integrated Circuits (ICs) | DigiKey

NJM5532D NJR Corporation/NJRC | Integrated Circuits (ICs) | DigiKey

The 4580 is a very common op-amp with average performance at best. I see these and the NJM2068 in tons of mixing consoles from the 90s. You can still buy them from Mouser / DigiKey. JRC means Japan Radio Corp in this case. What's it being used in?
