Questions

Is there a KiCad symbol and footprint for the SR70?

Yes. The symbol is EasyEDA_Cloud:SR70 and the footprint Package_TO_SOT_SMD:SOT-143, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SR70?

SOT-143-4, with 4 pins. Its footprint is drawn on this page.

Where is the SR70 datasheet?

TECH PUBLIC publishes it: the Datasheet link on this page opens it.

Where can I order the SR70?

JLCPCB lists it as part C907841, with 21,108 in stock; the sellers' links on this page open their listings.

What can replace the SR70?

Parts like it in the library: the CD143A-SR70 by Bourns, the SESR70 by SEMIWARE, the BSR70 by BORN and the SR70.TCT by SEMTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
