AP2012EC is a mechanically similar red 0805 LED, not a color-equivalent substitute.
APT2012CGCK is a green 0805 Kingbright indicator LED. Listed alternates need review because none match the green optical output.
Vf and If must be checked.
0805 size alone does not prove pad fit.
Discrete LED has no firmware.
Lifecycle is not fully stated.
No direct pin-compatible replacement is proven from this set.
Search for a green 2012/0805 LED with 2-pin polarity, 570 nm class output, 20 mA drive, and similar intensity.
Optical mismatch is the main risk.
