Replacement part for an RS-485 isolated transceiver

[Freshman]

Currently I am using this (IL4822
) RS-485 isolated transceiver (https://www.nve.com/Downloads/il4685.pdf) for my application and it is out of stock.
This is the closest alternative (ISO1452BDWR) that I could find (https://www.ti.com/lit/ds/symlink/iso1452.pdf?ts=1727783052393&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FISO1452%252Fpart-details%252FISO1452BDWR%253Futm_source%253Dgoogle%2526utm_medium%253Dcpc%2526utm_campaign%253Docb-tistore-promo-asc_opn_en-cpc-storeic-google-in%2526utm_content%253DDevice%2526ds_k%253DISO1452BDWR%2526DCM%253Dyes%2526gad_source%253D1%2526gclid%253DCj0KCQjwu-63BhC9ARIsAMMTLXR1xWzN_o18AoKFSpmAKJmsUYui8G7QEL30W4kPgP3XPj7EYOik59saAjHCEALw_wcB%2526gclsrc%253Daw.ds)

Can someone tell  me whether my selected alternative is fine? Or is it wrong? Any suggestions on the other possible available alternates for IL4822 are welcome.

Your original IC have integrated isolated DCDC converter while your alternative IC don't have it.

Thank you. So, just a clarification.

Could you please suggest an alternate part that would be a good replacement for the Original part? I tried in Digikey and mouser but couldn't find one correctly

If I knew the replacement part I would write, but to search it I have no time.
When 20 years ago I was using isolated RS485 I made it with 3 elements:
- signal isolator (one from ADuM serie),
- DCDC isolated converter,
- standard RS485 transceiver.

Never used part like you have.
