Is there a KiCad symbol and footprint for the SF2190B?

Yes. The symbol is EasyEDA_Cloud:SF2190B and the footprint EasyEDA_Cloud:FILTER-SMD_10P-L7.0-W5.0-P1.27-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SF2190B?

SMD7050-10P, with 10 pins. Its footprint is drawn on this page.

Where is the SF2190B datasheet?

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

Where can I order the SF2190B?

JLCPCB lists it as part C3283612, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SF2190B?

Parts like it in the library: the SF1146B by Murata, the SF2026B by Murata, the SF2145B by Murata and the SF2242B by Murata. Check their datasheets: a part that fits the footprint may still differ in its ratings.
