📌 Product Overview
The XINGLIGHT XL-B524SURUBW is a dual-color, 5mm through-hole LED designed for applications requiring combined red and blue signaling in a single component. Utilizing a diffused ("Aerosol") colloid, this device provides a wide viewing angle of 30 degrees, making it suitable for status indicators and dashboard lighting where uniform light diffusion is preferred over focused intensity.
🔑 The component supports a common anode configuration, simplifying PCB layout designs by sharing a positive voltage rail. It is engineered for long operational life and high energy efficiency, capable of fast switching speeds while maintaining low power consumption via DC drive.
🎯 Typical Applications
Based on its F5 package size and dual-color luminous characteristics, this model fits into the following design scenarios:
- Automotive Interior Lighting: Dashboard indicators and cabin status lights.
- Industrial Backlight Modules: Providing uniform illumination for switch panels or LCD edges.
- Signal Indication: Equipment status lights requiring Red (Stop/Error) and Blue (Info/Active) states.
- Smart Home Devices: Feedback LEDs for IoT hubs or appliances.
- General Illumination: Auxiliary lighting in confined spaces.

⚠️ Critical Warning: The soldering point must be at least 2.0mm away from the bottom of the colloid body to prevent thermal damage to the epoxy package and internal bond wires.
📦 Package, Dimensions & Assembly Notes
🔩 The XL-B524SURUBW utilizes an F5 radial leaded package with the following physical dimensions: L/W/H of 5.8mm x 5.0mm x 8.7mm. The overall length (including leads) is specified at 28mm.
- Visual Appearance: The lens features a diffused finish to scatter light effectively.
- Moisture Sensitivity: The component is classified at MSL Level 2, allowing for a floor life of up to 1 year at <30°C/60% RH before baking is required.
- Lead Integrity: Leads can withstand bending from 0° to 90° with a load of 2.5N, ensuring robustness during automated insertion processes.
- Packaging: Supplied in EIA standard compliant packaging for compatibility with standard radial leaders and taping equipment.
🏭 Sourcing & Supply Considerations
For procurement teams and supply chain managers, evaluating the XL-B524SURUBW should focus on the following:
- Binning & Consistency: Verify if the supplier can provide tight grouping for Wavelength (HB04-06/HR04-05) and Voltage (N12/N13 series) to ensure color consistency in end-products.
- Compliance: The product is fully ROHS compliant, meeting current environmental protection standards for electronic waste.
- Availability: Check for lead times on specific brightness grades (e.g., E1 High Brightness) which may differ from standard bins.
❓ Frequently Asked Questions
Q: What is the difference between the Red and Blue Forward Voltage?
A: The Blue chip requires a higher forward voltage (2.8V - 3.4V) compared to the Red chip (1.8V - 2.4V). If driving them in parallel, separate current limiting resistors are mandatory to prevent the Red LED from consuming excessive current or the Blue LED being too dim.
Q: Can this LED be used in outdoor environments?
A: The operating temperature range is -20°C to +85°C. While suitable for internal automotive modules, outdoor use requires an enclosure that protects the epoxy resin from prolonged UV exposure and moisture ingress, as the device is not rated as waterproof or IP67.
Q: What does "Diffused Colloid" mean for lighting design?
A: The diffused lens scatters the light, resulting in a softer, more wide-angle glow (30 degrees) rather than a focused spot. This is ideal for indicator panels where the viewer needs to see the light from various angles without glare.
Q: How do I handle the component for SMT assembly?
A: This is a Through-Hole Technology (THT) component. It is not suitable for standard SMT reflow ovens. It must be assembled using wave soldering (max 240°C) or manual hand soldering (max 300°C).
Q: What is the Moisture Sensitivity Level (MSL)?
A: The MSL is Level 2. This means the components can be exposed to ambient air (≤30°C/60% RH) for up to one year before they must be baked prior to soldering to prevent "popcorning" or internal cracking.
Q: Are there specific bin codes for sorting?
A: Yes. Brightness is sorted into codes A5-E1, Voltage into N12/N13, and Wavelength into HB/HR codes. Specifying these bin codes in your purchase order is critical for visual consistency in mass production.
