Overview
The CAT25040P is an EEPROM made by onsemi in a PDIP-8 package with 8 pins.
PCBKit's library has its KiCad symbol (Memory_EEPROM:CAT250xxx, from KiCad's library) and its footprint (Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C6479049).

Questions
Is there a KiCad symbol and footprint for the CAT25040P?
Yes. The symbol is Memory_EEPROM:CAT250xxx and the footprint Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CAT25040P?
PDIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the CAT25040P datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the CAT25040P?
JLCPCB lists it as part C6479049, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CAT25040P?
Parts like it in the library: the 25AA256-I/P by Microchip Technology, the 25AA320A-I/P by Microchip Technology, the 25AA640A-I/P by Microchip Technology and the 25LC256-I/P by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
