Is there a KiCad symbol and footprint for the LM2903BYST?
Yes. The symbol is Comparator:LM2903 and the footprint EasyEDA_Cloud:MSOP-8_L3.0-W3.0-P0.65-LS4.9-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM2903BYST?
MiNiSO-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM2903BYST datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LM2903BYST?
JLCPCB lists it as part C5751810, with 10 in stock; the sellers' links on this page open their listings.
What can replace the LM2903BYST?
Parts like it in the library: the NJM12903RB1-TE1 by Nisshinbo Micro Devices Inc.. Check their datasheets: a part that fits the footprint may still differ in its ratings.
