Sold as an APA102 equivalent and usually substituted for one without comment. It is close, but see the protocol page: global brightness works differently (a real current source, so no flicker when dimmed), PWM is 4.7 kHz rather than 20 kHz, and end-frame handling differs.

APA102
Widely sold as an APA102 equivalent and usually works, but it is not a drop-in. Global brightness is a controlled current source rather than superimposed PWM, so it does not flicker when dimmed. PWM is 4.7 kHz against 20 kHz. The update is non-staggered, and end-frame handling differs - a driver that relies on the APA102's end-frame behaviour can misbehave. source ↗

near clone of this
APA102
Frequently sold as interchangeable and usually works, but the SK9822 implements global brightness as a real current source rather than superimposed PWM, runs a lower PWM frequency, updates non-staggered, and differs in end-frame handling. Not reliably drop-in.

Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
