A 2.0 x 2.0 x 0.9 mm four-pad chip LED, from a maker that is not in the usual WS2812 supply chain. Pin numbering runs clockwise from the marked corner and the pad order is 1 DOUT, 2 VDD, 3 DIN, 4 VSS: not the WS2812B-2020 order (1 DO, 2 GND, 3 DI, 4 VDD). The bit-code test in the sheet lights red with 0x00FF00, i.e. GRB order.

Numbers run clockwise from the marked corner, unlike the WS2812 family. Pad sizes read from the 0.55 mm callouts; positions approximate. What this means.

Compatibility

  • protocol compatible SK6812

    On paper only: nominal 300/900/900/300 ns against the SK6812 datasheet's 300/900/600/600 and FastLED's 300/900/900/300, same GRB order, reset 200 us against the SK6812's 80 us (the current OPSCO sheet also says 200 us). No Wurth part has been driven from a SK6812 driver by this catalogue. source ↗

  • protocol compatible of this WL-ICLED (PLCC4 5050 timing)

    Same 24-bit GRB frame and nominal bit times. The datasheet windows, PWM frequency (2.5 kHz against 4-6 kHz), supply minimum (3.5 V against 3.3 V) and propagation delay differ, so Wurth treats them as separate silicon behaviours.

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.
