Questions

Is there a KiCad symbol and footprint for the CAT523L?

Yes. The symbol is EasyEDA_Cloud:CAT523L and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CAT523L?

SOIC-14, with 14 pins. Its footprint is drawn on this page.

Where is the CAT523L datasheet?

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

Where can I order the CAT523L?

JLCPCB lists it as part C7100351, with 0 in stock; the sellers' links on this page open their listings.

What can replace the CAT523L?

Parts like it in the library: the AD8402ARZ10-REEL by Analog Devices, the MCP4251-503E/SL by Microchip Technology, the MCP4251-103E/SL by Microchip Technology and the MCP4231-502E/SL by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
