Questions

Is there a KiCad symbol and footprint for the WR0205?

Yes. The symbol is EasyEDA_Cloud:WR0205 and the footprint EasyEDA_Cloud:SOT-223-3_L6.5-W3.4-P2.30-LS7.0-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the WR0205?

SOT-223-3L, with 4 pins. Its footprint is drawn on this page.

Where is the WR0205 datasheet?

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

Where can I order the WR0205?

JLCPCB lists it as part C2901042, with 151 in stock; the sellers' links on this page open their listings.

What can replace the WR0205?

Parts like it in the library: the BT131-600D by WEIDA, the S602TSRP by Littelfuse, the DT1T5G-B by Doeshare and the L0103MTRP by Littelfuse. Check their datasheets: a part that fits the footprint may still differ in its ratings.
