Questions

Is there a KiCad symbol and footprint for the DS1302?

Yes. The symbol is adafruit:DS1302 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 DS1302?

SOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the DS1302 datasheet?

TDD publishes it: the Datasheet link on this page opens it.

Where can I order the DS1302?

JLCPCB lists it as part C55488570, with 1,936 in stock; the sellers' links on this page open their listings.

What can replace the DS1302?

Parts like it in the library: the DS1302Z by JSMSEMI, the BM8563ESA by GATEMODE, the DS1307ZM/TR by HGSEMI and the PCF8563 by IDCHIP. Check their datasheets: a part that fits the footprint may still differ in its ratings.
