Questions

Is there a KiCad symbol and footprint for the SC187ULTRT?

Yes. The symbol is EasyEDA_Cloud:SC187ULTRT and the footprint EasyEDA_Cloud:MLPQ-16-UT_L3.0-W3.0-P0.50-BL-EP1.7, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SC187ULTRT?

MLPQ-16(3x3), with 17 pins. Its footprint is drawn on this page.

Where is the SC187ULTRT datasheet?

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

Where can I order the SC187ULTRT?

JLCPCB lists it as part C2073294, with 255 in stock; the sellers' links on this page open their listings.

What can replace the SC187ULTRT?

Parts like it in the library: the SC185HULTRT by SEMTECH, the SC185JULTRT by SEMTECH and the SC185LULTRT by SEMTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
