Is there a KiCad symbol and footprint for the REF7040QFKHT?
Yes. the footprint EasyEDA_Cloud:CRYSTAL-SMD_8P-L5.0-W5.0-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the REF7040QFKHT?
LCCC-8(4.5x5), with 8 pins. Its footprint is drawn on this page.
Where is the REF7040QFKHT datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the REF7040QFKHT?
JLCPCB lists it as part C17702280, with 22 in stock; the sellers' links on this page open their listings.
What can replace the REF7040QFKHT?
Parts like it in the library: the ADR4540BRZ-R7 by Analog Devices, the ADR4540ARZ by Analog Devices, the ADR4540BRZ by Analog Devices and the MAX6126AASA41+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
