Questions

Is there a KiCad symbol and footprint for the SDB21G?

Yes. The symbol is EasyEDA_Cloud:TPS61040DBVRG 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 SDB21G?

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

Where is the SDB21G datasheet?

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

Where can I order the SDB21G?

JLCPCB lists it as part C521419, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SDB21G?

Parts like it in the library: the MT3540-F23 by XI'AN Aerosemi Tech, the TLV62569DBV by Texas Instruments, the SY8089AAAC by 矽力杰silergy and the SY8089A1AAC by 矽力杰silergy. Check their datasheets: a part that fits the footprint may still differ in its ratings.
