Is there a KiCad symbol and footprint for the SR70.TCT?
Yes. The symbol is EasyEDA_Cloud:SR70.TCT 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.TCT?
SOT-143, with 4 pins. Its footprint is drawn on this page.
Where is the SR70.TCT datasheet?
SEMTECH publishes it: the Datasheet link on this page opens it.
Where can I order the SR70.TCT?
JLCPCB lists it as part C512378, with 32 in stock; the sellers' links on this page open their listings.
What can replace the SR70.TCT?
Parts like it in the library: the CD143A-SR70 by Bourns, the SESR70 by SEMIWARE, the SR70 by TECH PUBLIC and the BSR70 by BORN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
