The WS2812E in the 1313 package - the part the old catalogue entry “WS2812E (3535)” was really pointing at: its recorded LCSC SKU C5446700 is this 1.3 mm part, not a 3535.

Compatibility

  • protocol compatible WS2812B-V5

    Identical datasheet timing windows, pin count (4) and supply range. Independent measurement has not been done; E and B differ in IC drive current (12-12.5 mA) and packages (the E exists in 1313, 2020, 2427, 3535-class MINI and 4020). source ↗
