Questions

Is there a KiCad symbol and footprint for the SC189LSKTRT?

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 SC189LSKTRT?

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

Where is the SC189LSKTRT datasheet?

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

Where can I order the SC189LSKTRT?

JLCPCB lists it as part C842844, with 7 in stock; the sellers' links on this page open their listings.

What can replace the SC189LSKTRT?

Parts like it in the library: the JW5223 by JoulWatt Tech, the S-8353J18MC-IYDT2U by ABLIC, the HT7718B by Holtek Semicon and the R1223N182H-TR-FE by Nisshinbo Micro Devices Inc.. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SC189LSKTRT?

3 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
