TCWIN T63: a 2.0 x 1.7 x 0.85 mm built-in-IC LED (sheet: looks like a 2017 LED), 12 mA per channel (9.6-14.4), version A5 dated 2024-07-18. Pins 1 DO, 2 GND, 3 DIN, 4 VDD, numbered counter-clockwise from the bottom-right in the top view: the same order as TX1812IXA5 (tx1812-2017) and T65, but with a different timing window set (T0H 220/300/400 ns, T0L 550/600/950 ns). The sheet’s land pattern (0.77 x 0.80 mm pads, 0.20 mm gap) differs from TX1812IXA5’s.

Outline and pin positions checked against the manufacturer datasheet (C48982516 T63 rev A5 p4). Half-moon notched pads at the two 2.0 mm ends (drawn square). The sheet shows a green bar / triangle mark and does not say what it denotes; pins are numbered in the top view. Pad size 0.52 x 0.70 mm, 0.97 mm between inner edges, 0.20 mm gap. What this means.

Compatibility

  • protocol compatible TX1812

    The TX1812 sheets print T0H 245-345 and T0L 545-645 ns; the typical 295 / 595 ns pair lies inside the T63 windows (220-400 / 550-950 ns) and the T63 typicals (300 / 600 ns) lie inside the TX1812 windows, so one stream satisfies both printed sets. Supply, GRB framing and the other electrical tables are the same. Numbers only; no sheet relates the two, and nothing was measured. source ↗
