Is there a KiCad symbol and footprint for the APT2012EC?
Yes. The symbol is Device:LED and the footprint LED_SMD:LED_0805_2012Metric, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the APT2012EC?
0805, with 2 pins. Its footprint is drawn on this page.
Where is the APT2012EC datasheet?
Kingbright publishes it: the Datasheet link on this page opens it.
Where can I order the APT2012EC?
JLCPCB lists it as part C5879378, with 8,327 in stock; the sellers' links on this page open their listings.
What can replace the APT2012EC?
Parts like it in the library: the KT-0805G by Hubei KENTO Elec, the KT-0805W by Hubei KENTO Elec, the F.0805.00004/P2-0805G2TS2-08T-002 by TUOZHAN and the TZ-P2-0805BTCS2-0.8T by TUOZHAN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
