Is there a KiCad symbol and footprint for the LM2903BIDDF?
Yes. The symbol is Comparator:LM2903 and the footprint Package_TO_SOT_SMD:TSOT-23-8, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM2903BIDDF?
TSOT-23-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM2903BIDDF datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM2903BIDDF?
JLCPCB lists it as part C2877599, with 370 in stock; the sellers' links on this page open their listings.
What can replace the LM2903BIDDF?
Parts like it in the library: the LM393BIDDFR by Texas Instruments, the TLV3502AIDCNR by Texas Instruments, the TLV7022DDF by Texas Instruments and the MAX9032AKA+T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
