Questions

Is there a KiCad symbol and footprint for the REF3033AIDBZR?

Yes. The symbol is Reference_Voltage:REF3033 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the REF3033AIDBZR?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the REF3033AIDBZR datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the REF3033AIDBZR?

JLCPCB lists it as part C36658, with 26,373 in stock; the sellers' links on this page open their listings.

What can replace the REF3033AIDBZR?

Parts like it in the library: the LT1460HCS3-3.3#TRPBF by Analog Devices, the LT1460JCS3-3.3#TRPBF by Analog Devices, the LT1460KCS3-3.3#TRPBF by Analog Devices and the REF3033AIDBZT by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
