Side-emitting package: light leaves the long edge rather than the top. Used for edge-lighting acrylic and for lighting along a surface rather than away from it.

Compatibility
-
drop in
WS2812B
Timings overlap enough that WS2812B code drives it without changes, and the 5050 footprint and pinout match. The differences that matter are better PWM frequency and a shorter required reset. source ↗
-
protocol compatible of this
SK6812 RGBW
Identical timing, but four channels rather than three. Driving it with an RGB library shifts colours down the strip, because every pixel consumes one extra byte.
-
electrically similar of this
SK6822
Same family and single-wire scheme, but a 1750 ns bit period against the SK6812's 1200 ns. Not interchangeable at the same timings.
Dating evidence
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.
