Questions
Is there a KiCad symbol and footprint for the L4971D?
Yes. The symbol is EasyEDA_Cloud:L4971D and the footprint Package_SO:SOIC-16W_7.5x10.3mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L4971D?
SO-16-300mil, with 16 pins. Its footprint is drawn on this page.
Where is the L4971D datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L4971D?
JLCPCB lists it as part C1355738, with 2 in stock; the sellers' links on this page open their listings.
What can replace the L4971D?
Parts like it in the library: the UC3825ADWTR by Texas Instruments, the UC3825ADW by Texas Instruments, the UC3825DW by Texas Instruments and the UC2856QDW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
