TONYU · LED Indication - Discrete · LED_D3.0mm
DY-204SUBC-H44-SN-A9 from TONYU, in a LED_D3.0mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Cathode | passive | LED cathode; lead spacing 2.54 mm, solder at least 3 mm from the epoxy body at max 260 °C for 3 s or less (wave soldering). |
| 2 | Anode | passive | LED anode; forward current IF max 25 mA (VF 2.8-3.4 V at IF=20 mA), reverse voltage VR max 5 V, so a series protection resistor is needed. |

Materials and finish
As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).
| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
| contacts | tin | The kinked tooling scrape easily the pin of LED, where the LED bracket is rusting easily, especial expose it in moist air. To decrease the LED bracket rust, advise using plated tin LED bracket. | 8 |
