Is there a KiCad symbol and footprint for the GC1307?
Yes. The symbol is EasyEDA_Cloud:DS1338Z-18+ and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the GC1307?
SOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the GC1307 datasheet?
Gcore publishes it: the Datasheet link on this page opens it.
Where can I order the GC1307?
JLCPCB lists it as part C504378, with 2,975 in stock; the sellers' links on this page open their listings.
What can replace the GC1307?
Parts like it in the library: the RX8010SJ by Seiko Epson, the GC1302 by Gcore, the SD2058 by WAVE and the SD2068 by WAVE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
