Questions

Is there a KiCad symbol and footprint for the CH451S?

Yes. The symbol is EasyEDA_Cloud:CH451S and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH451S?

SOP-28-300mil, with 28 pins. Its footprint is drawn on this page.

Where is the CH451S datasheet?

WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.

Where can I order the CH451S?

JLCPCB lists it as part C46001, with 12 in stock; the sellers' links on this page open their listings.

What can replace the CH451S?

Parts like it in the library: the CH452A by WCH (Nanjing Qinheng Microelectronics), the MAX7219EWG+T by Maxim Integrated (Analog Devices), the HX7219CDWRG by HANSCHIP semiconductor and the MAX7219M/TR by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
