Questions

Is there a KiCad symbol and footprint for the SC189CSKTRT?

Yes. The symbol is EasyEDA_Cloud:SC189YSKTRT and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SC189CSKTRT?

SOT-23-5, with 5 pins. Its footprint is drawn on this page.

Where is the SC189CSKTRT datasheet?

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

Where can I order the SC189CSKTRT?

JLCPCB lists it as part C783594, with 216 in stock; the sellers' links on this page open their listings.

What can replace the SC189CSKTRT?

Parts like it in the library: the XC9235B12CMR-G by Torex Semiconductor, the XC9236B12DMR-G by Torex Semiconductor, the XC9237C12CMR-G by Torex Semiconductor and the XC9237C12DMR-G by Torex Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SC189CSKTRT?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
