TPS23841: TPS23841 PoE management

Part Number: TPS23841

Hi all,


I have an obsolescence problem with the optocouplers suggested for the I2C communication of TPS23841.
Texas Instrument indicates the PS8821-2 in this AN:

Now these optocouplers are in EOL..
Whitch optocouplers can I use as replacement?

Thanks in advance,
Diego.
