TONYU’s WS2812B-shaped 5050 pixel (same 5.4 x 5.0 outline, pads and pin order as the WorldSemi WS2812B-5050) with its own “6812F” IC; “NL” and “1T” are the maker’s suffixes and the sheet does not explain them. Pin names: the sheet’s table lists DOUT, GND, VDD, DIN without numbers; the numbers come from the package profile (1 VDD, 2 DOUT, 3 VSS, 4 DIN).

The feature list says “30 frames per second: 512 pixels in low-speed mode and 1024 in high-speed mode” and, twice, that the circuit is in a 5050 package. LCSC stock 450.

Compatibility

  • electrically similar SK6812

    Inferred from the printed numbers and the part code only; the TONYU sheet never names SK6812 or any other vendor. Its windows (T0H 200-400, T0L at least 800, T1H 580-1000, T1L at least 200 ns, 24 bits GRB, 1.2 us symbol) overlap OPSCO's current SK6812 sheet (T0H 250-400, T0L at least 800, T1H 650-1000, T1L at least 200 ns). Differences: reset above 80 us against above 200 us in OPSCO's 2025 sheet, and a 1.2 kHz PWM. source ↗

  • electrically similar of this TONYU 6805

    Identical timing and IC tables in the two TONYU sheets; the 6805 part is the 5 mA (photometric table at IF = 5 mA, 1.5 x 1.5 mm) one and the 6812F the 12 mA (IF = 12 mA, 5050) one. The sheets do not say whether the current is set by the die or by the LED chips used.

  • electrically similar of this TONYU 6812 (TR2)

    The 2024 TR2 sheet is a newer, different table from the 2019-era 6812F sheet: reset above 200 us (6812F: above 80 us), T1H 600/670/1000 ns (580/640/1000), PWM 1.0 kHz (1.2), quiescent 0.6 mA (1 mA), and logic thresholds of 2.8 / 1.8 V absolute rather than 0.7 / 0.3 x VDD.

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.
