XINGLIGHT XL-1608SURC-06

Product FAQ

• 1. To ensure longevity and optimal brightness for this 0603 Red LED, you must limit the current. With a Forward Voltage (V_f) of 2.3V and a typical Forward Current (I_f) of 20mA:
  ●For a 3.3V Rail: Use a 50Ω to 100Ω resistor (R = (3.3V - 2.3V) / 0.02A = 50Ω). ●For a 5V Rail: Use a 135Ω to 150Ω resistor (R = (5V - 2.3V) / 0.02A = 135Ω). ●Pro-tip: For status indicators where maximum brightness isn't required, increasing the resistance to 330Ω or 470Ω will significantly reduce power consumption and extend the component's lifespan.
• 2. Can the XINGLIGHT XL-1608SURC-06 Be Used as a Drop-in Replacement for Standard 0603 Red LEDs From Kingbright or Lite-On?
  Yes. The XL-1608SURC-06 features a standard 0603 (1608 Metric) footprint and a water-clear lens, making it a highly compatible alternative to premium brands. Key specs like its 625nm dominant wavelength and 225mcd luminous intensity match or exceed many industry-standard indicators. However, always verify the V_f (2.3V) in your specific circuit, as some low-power red LEDs may have a slightly lower forward voltage (around 1.8V-2.0V).
• 3. Is the 225mcd Brightness of the XL-1608SURC-06 Sufficient for Daylight-visible Status Indicators?
  With a luminous intensity of 225mcd and a wide 120-degree viewing angle, this LED is excellent for indoor panels and well-lit office environments. While it provides sharp contrast behind most plastic overlays, it may not be "sunlight readable" for direct outdoor use. For optimal visibility, the 625nm Red wavelength is chosen specifically to provide a pure red hue that is easily distinguishable from orange-red or amber signals.
• 4. What Is the Recommended Reflow Soldering Profile for the XL-1608SURC-06 SMD LED?
  This SMD component is designed for automated SMT assembly. The recommended Pb-Free reflow soldering peak temperature is 260°C for a maximum of 10 seconds. It is crucial to manage moisture sensitivity; once the vacuum seal is broken, the components should be mounted within 168 hours (MSL 3). For manual soldering, ensure the iron temperature does not exceed 300°C for more than 3 seconds to avoid damaging the internal die or the 0603 epoxy casing.
• 5. Why Choose the XL-1608SURC-06 (LCSC Part C965799) for High-volume Consumer Electronics?
  The XL-1608SURC-06 offers a superior price-to-performance ratio for mass production. By sourcing XINGLIGHT through LCSC, engineers get a AEC-Q style consistency in a standard industrial grade part. With massive stock availability (millions of units) and a significantly lower unit cost compared to Western brands, it is the ideal choice for BOM cost reduction (Value Engineering) in IoT devices, consumer wearables, and household appliances without sacrificing optical clarity.
