Questions

Is there a KiCad symbol and footprint for the L6983C50Q?

Yes. the footprint EasyEDA_Cloud:TQFN-16_L3.0-W3.0-P0.50-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L6983C50Q?

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

Where is the L6983C50Q datasheet?

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

Where can I order the L6983C50Q?

JLCPCB lists it as part C509129, with 0 in stock; the sellers' links on this page open their listings.

What can replace the L6983C50Q?

Parts like it in the library: the L6983N50Q by STMicroelectronics, the LT8640EUDC#TRPBF by Analog Devices, the D2576HV-5.0(F) by Silicore and the HYM2596S-5.0 by Haoyu Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
