Questions

Is there a KiCad symbol and footprint for the ERTJ0ER104F?

Yes. The symbol is Device:Thermistor_NTC and the footprint Resistor_SMD:R_0402_1005Metric, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ERTJ0ER104F?

0402, with 2 pins. Its footprint is drawn on this page.

Where is the ERTJ0ER104F datasheet?

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

Where can I order the ERTJ0ER104F?

JLCPCB lists it as part C236279, with 3,500 in stock; the sellers' links on this page open their listings.

What can replace the ERTJ0ER104F?

Parts like it in the library: the NCP15WF104F03RC by Murata, the CMFX 104F3950 by Nanjing Shiheng Elec, the SDNT1005X104F4250FTF by Sunlord and the NTCG104EF104FTDSX by TDK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
