3.2 x 2.7 x 0.8 mm. All three SKUs use the MX3 cell (0.295 / 0.595 us). Datasheets disagree: the CT-3227URGBC sheets say the data go out in RGB order while the 2026 UGRBC-MX3 sheet says GRB; the sheet’s text says an 80 us reset, matching the table. LCSC stock: C52191340 1,820, C52676102 2,980, C56145024 3,000.

Outline and pin positions checked against the manufacturer datasheet (C52191340 CT-3227URGBC/H-P8 A1 p1). Circled numbers: 1 top-left, 2 top-right, 3 bottom-right, 4 bottom-left (clockwise); pins 1 GND, 2 DOUT, 3 VDD, 4 DIN - GND is pin 1 here, unlike the 1615 and 2018 packages. Bottom-view pads 0.6 x 1.0 mm, 2.0 mm between columns and 0.6 mm between rows; the PCB land is 0.7 x 1.1 mm. A green bar at the left edge is the only mark. What this means.

Compatibility
-
protocol compatible
Yongyu 0.3 / 0.6 single-wire IC (BRG / RGB IC series)
The Yongyu YY-0807RGBJ26-07-FJ sheet prints the identical 0.295 / 0.595 / 0.595 / 0.295 us table with a reset >=80 us; tolerance differs (+/-0.15 us there). Same-number match only; neither maker names the other. source ↗

protocol compatible of this
Beking 12 mA single-wire IC (1615)
Same 295 / 595 / 595 / 295 ns timing with a +/-50 ns tolerance, an 80 us reset and 12 mA drive as the Chongtian MX3 sheets; GRB in both. Neither maker names the other.

protocol compatible of this
Yongyu 0.3 / 0.6 single-wire IC (BRG / RGB IC series)
The FJ table equals the Chongtian MX3 table (295 / 595 / 595 / 295 ns, reset 80 us) and both are GRB, 800 kHz; the FI table is 300 / 600 / 600 / 300 ns +/-50. Tolerances differ; neither maker names the other.
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.
Where to buy
Stub data — a few rows so purchase links can grow later. Prices are not tracked.
