Overview
The LR2003A is a darlington Transistor Array made by Leshan Radio (LRC) in a DIP-16 package with 16 pins. Seven channels DIP-16 Darlington Transistor Arrays ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:LR2003A, from EasyEDA) and its footprint (Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C79256).

Is there a KiCad symbol and footprint for the LR2003A?
Yes. The symbol is EasyEDA_Cloud:LR2003A and the footprint Package_DIP:DIP-16_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 LR2003A?
DIP-16, with 16 pins. Its footprint is drawn on this page.
Where is the LR2003A datasheet?
Leshan Radio (LRC) publishes it: the Datasheet link on this page opens it.
Where can I order the LR2003A?
JLCPCB lists it as part C79256, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LR2003A?
Parts like it in the library: the ULN2003AN225 by GREENMICRO, the ULN2003 by Silicore, the ULN2003AN by HGSEMI and the SN75468N-TUDI by Tudi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
