4020 Addressable SMD LEDs , complete part number HC-S4020ISRGBAC-G3. Uses a 4020 package measuring 4.0×2.0×1.75mm, integrating RGB LEDs and a control IC, and supporting top and side mounting. Uses single-wire serial data and unipolar return-to-zero coding, with a typical data rate of 800kHz and typical IC supply voltage of 5V (not LED forward voltage). Pin 1 is DIN, 2 is VDD, 3 is DOUT and 4 is GND. Optical parameters for each channel are tested at 12mA. Download the original PDF on this page for complete parameters and pad 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 placement-machine accuracy does this LED require?
A: This 4020 package (4.0×2.0mm) has relatively large pads. A standard high-speed placement machine is sufficient, with no special accuracy requirements. It has an integrated IC and multiple pads. Stencil apertures must align individually with the pads; visual inspection or AOI after placement is recommended to verify solder-joint quality. Lead-free reflow soldering is supported (260℃ peak for no more than 10 seconds; see the datasheet for the full profile).

Ordering and Inquiry Information
SMD models use tape-and-reel packaging (2000pcs/reel, see PDF page 10), with a minimum order in full reels. Sample lead time is generally 3-4 working days; volume production lead time is generally 10-15 working days (subject to order confirmation). Confirm volume pricing through the inquiry option on this page or Tel/WeChat 139 2571 4318. Specify the exact model and quantity in your inquiry.
Selection Recommendations
This model uses a built-in control IC. Connect power and signals according to the VDD, DIN, DOUT and GND definitions in the current datasheet; do not treat the IC supply voltage as LED VF in a current-limiting formula. On PDF page 5, the 24bit diagram shows G-R-B while the adjacent text states RGB order, an inconsistency. Confirm communication byte order with the manufacturer or through sample communication testing. Set reflow soldering according to the profile in this file.
