Questions

Is there a KiCad symbol and footprint for the SDB628?

Yes. The symbol is EasyEDA_Cloud:CJ9340T6 and the footprint Package_TO_SOT_SMD:SOT-23-6, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SDB628?

SOT-23-6, with 6 pins. Its footprint is drawn on this page.

Where is the SDB628 datasheet?

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

Where can I order the SDB628?

JLCPCB lists it as part C77805, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SDB628?

Parts like it in the library: the SX1308 by SX, the SB6286 by SHOUDING and the MAX629ESA+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SDB628?

6 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
