Is there a KiCad symbol and footprint for the SIT490EEPA?
Yes. The symbol is EasyEDA_Cloud:ADM3077EARZ-REEL-TUDI and the footprint Package_DIP:DIP-8_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SIT490EEPA?
DIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the SIT490EEPA datasheet?
SIT publishes it: the Datasheet link on this page opens it.
Where can I order the SIT490EEPA?
JLCPCB lists it as part C2838012, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SIT490EEPA?
Parts like it in the library: the MAX485EN by HTC, the HGX3485ECN by HGSEMI, the HGX3485EIN by HGSEMI and the HGX485EIN by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
