Questions

Is there a KiCad symbol and footprint for the VIPER25HN?

Yes. The symbol is Regulator_Switching:VIPer25HN and the footprint Package_DIP:PowerIntegrations_PDIP-8B, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the VIPER25HN?

DIP-7, with 7 pins. Its footprint is drawn on this page.

Where is the VIPER25HN datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the VIPER25HN?

JLCPCB lists it as part C3094727, with 0 in stock; the sellers' links on this page open their listings.

What can replace the VIPER25HN?

Parts like it in the library: the LNK306PN by POWER INTEGRATIONS, the LNK364PN by POWER INTEGRATIONS, the TNY266PN by POWER INTEGRATIONS and the LNK304PN by POWER INTEGRATIONS. Check their datasheets: a part that fits the footprint may still differ in its ratings.
