Questions

Is there a KiCad symbol and footprint for the A5973D?

Yes. the footprint EasyEDA_Cloud:SO-8_L4.9-W3.9-P1.27-LS6.0-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the A5973D?

SO-8-EP, with 9 pins. Its footprint is drawn on this page.

Where is the A5973D datasheet?

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

Where can I order the A5973D?

JLCPCB lists it as part C1355697, with 0 in stock; the sellers' links on this page open their listings.

What can replace the A5973D?

Parts like it in the library: the AP64352SP by Diodes Incorporated, the LMR36520ADDAR by Texas Instruments, the LMR36520FADDA by Texas Instruments and the TPS54627DDAR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
