TX1813 in a five-pad 3.2 x 1.0 x 1.4 mm package (the sheet calls it a 3010 LED), 5 mA per channel, sheet version A2 dated 2023-03-27 (PDF signature 2023-04-10). Pins (p4-5): 1 DIN, 2 VDD, 3 FDIN (backup data input), 4 DO, 5 GND. The sheet draws the part twice, with a recommended side-mount pad row and a recommended face-mount land pattern; the drawing here follows the labelled top view (1 DIN top-left, 2 VDD bottom-left, 3 FDIN top-middle, 4 DO bottom-right, 5 GND top-right). The sheet does not say whether it emits from the face or the long edge. Exact pad sizes are approximate.

TX1813YWA5 has no datasheet on LCSC; listed by the shared IC code 1813 and package letter Y (inference).

No datasheet is listed on LCSC for this SKU. Package, pin order and drawing are taken from the sibling sheet TX1813Y5 because both share IC code 1813 and package letter Y; that is an inference from the part number, not something any sheet states. Drive current, timing window and the meaning of the remaining letters are not confirmed for this SKU. LCSC stock 3,890 on 2026-10-15.

Outline and pin positions checked against the manufacturer datasheet (C3975084 TX1813Y5 rev A2 p4). Five pads in the sheet top view (1 DIN top-left, 2 VDD bottom-left, 3 FDIN top-middle, 4 DO bottom-right, 5 GND top-right). The sheet also shows a side-mount pad row and a face-mount land pattern; pad sizes here are approximate. What this means.

Compatibility

  • protocol compatible TX1812

    Identical printed windows, supply range, drive-current options and 24-bit GRB framing; TX1813 adds the FDIN backup data input. Numbers only; the sheets never relate the two ICs. What FDIN does is not explained in any TX1813 sheet. source ↗

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.
