Is there a KiCad symbol and footprint for the VIPER25LN?
Yes. The symbol is Regulator_Switching:VIPer25LN 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 VIPER25LN?
DIP-7, with 7 pins. Its footprint is drawn on this page.
Where can I order the VIPER25LN?
JLCPCB lists it as part C17550737, with 0 in stock; the sellers' links on this page open their listings.
What can replace the VIPER25LN?
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.
