Quick Reference: Key Optoelectronic Parameters (by Emission Color)
Optical test conditions: Ta=25℃, IF=5 mA, based on page 3 of this model's datasheet. See page 4 for operating temperature. The datasheet does not list per-color forward voltage VF or numerical viewing angles; page 7 provides a light distribution curve. Chip supply voltage VDD is listed below and differs from LED forward voltage VF.
| Emission Color | Part Number | Forward Voltage VF(V) | Wavelength / Color Temperature CCT | Luminous Intensity Iv (mcd) | Viewing Angle 2θ1/2 (°) | Test Current IF (mA) | Operating Temperature |
|---|---|---|---|---|---|---|---|
| Red | HC-IC4X15F-B2020RGB8CGH | 1.8~2.4 | 620～630 nm | 75～120 | — | 5 | -40 ~ +85℃ |
| Green | 2.5~3.2 | 515～530 nm | 170～300 | — | 5 | -40 ~ +85℃ | |
| Blue | 2.5~3.2 | 460～475 nm | 45～100 | — | 5 | -40 ~ +85℃ |

2020 4-Pin Addressable SMD LEDs A 5V addressable SMD LED with an integrated driver IC (compatible with WS2812/SK6812 single-wire serial protocols). Each LED supports individually programmable full-color addressing and cascade control, for light strips, ambient lights and pixel matrices. Supplied directly by Dongguan Hongcheng Optoelectronics Co., Ltd. (an international member of Guangyu Group, with over 20 years of LED packaging experience). Uses A-grade chips and 99.99% pure gold wire bonding, with RoHS certification. Free samples and custom IC protocols, pin configurations and refresh rates are available. Download the datasheet PDF on this page for complete electrical specifications and mounting dimensions.
Q: What are the chromaticity BIN ranges for addressable LEDs?
A: The full-color series is shipped with brightness and color binning based on CIE chromaticity coordinates. Color difference within the same batch is Δu'v'≤0.003. Custom BIN ranges are available to meet customer color-gamut requirements.
Q: What is the difference between four-pin and six-pin 2020 addressable LEDs?
A: The four-pin version uses standard single-wire data transmission. The six-pin version adds a backup data line (break-point data continuity), so failure of one LED does not affect subsequent LEDs. The six-pin version is recommended for long cascaded LED strip projects.
Q: What placement-machine accuracy does this LED require?
A: This product uses a 2020 package (2.0×2.0mm) with relatively large pads. Ordinary high-speed placement machines meet its needs, with no special equipment accuracy requirements. Its built-in IC and multiple-pad structure require each stencil aperture to align with its corresponding pad. Visual inspection or AOI is recommended after placement to confirm solder quality. Supports lead-free reflow soldering (peak ≤260℃/≤3s).
