Placeholder for three LCSC SKUs whose listing says SMD3535-4P and for which no datasheet exists on LCSC: TX1812HWBA-F01, TX1812HWCA-F02 and TX1812EWCA-F10-E. The only 3535 TX1812 sheet held (HLA-F01) is a six-pin part, so its pinout is deliberately not copied here, and no sheet explains the letter E. Pin count 4 and the 3.5 x 3.5 mm size are LCSC’s package field, not a datasheet reading. Pinout, drawing, drive current and thickness are unknown.

Protocol — TX1812
Timings shown from datasheet.
Compatibility
-
protocol compatible of this
TCWIN T62
The T62 electrical and timing tables are word for word the TX1812 5 mA tables (windows, 3.5-5.5 V, 4 kV ESD, 5 mA, GRB). The T62 sheet never mentions TX1812; this edge is based on the identical numbers only.

protocol compatible of this
TCWIN T63 group
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.

protocol compatible of this
TCWIN T80
T80 is the same 6028 footprint as TX1812DQ-F01 and its T0H / T1L windows equal the TX1812 ones; its T0L / T1H windows (545-1200 ns) contain the TX1812 typical 595 ns. Numbers only; nothing measured and no sheet relates the two.
-
protocol compatible of this
TX1812CXA5
Same pin order, supply, 24-bit GRB framing and electrical table; only the printed timing windows differ (T0L/T1H 550-1200 ns here against 545-645 ns). The nominal values of the other TX1812 sheets (295 / 595 ns) lie inside these windows on T0H, T0L, T1H and T1L, so a stream built for those sheets is inside both sets of printed windows; the reverse is not true (900 ns is outside 545-645). Numbers only, never measured.
-
protocol compatible of this
TX1813
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.
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
