📌 Product Overview
The XINGLIGHT XL-502UYD is a standard 5mm (F5) radial leaded LED featuring a yellow colloid and a dominant wavelength of 590nm. Designed as a reliable light source for through-hole PCB assembly (THT), it offers a balance of luminous intensity and power efficiency. With a viewing angle of 30 degrees, this component is engineered for applications requiring focused indication rather than diffuse illumination. 💡 The device is constructed with a yellow epoxy lens and utilizes standard EIA packaging, making it suitable for high-volume automated insertion processes.
🔧 Typical Applications
- Industrial Indication & Control: 🏭 Utilized in control panels, relay status indicators, and industrial automation equipment for clear signal transmission.
- Consumer Electronics & Appliances: 📺 Integrated into home appliances (washing machines, microwaves) and digital devices for power status or operation mode display.
- Automotive & Transportation: 🚗 Applied to dashboard indicators and interior lighting systems, leveraging the 585-595nm wavelength for high visibility.
- Educational & Development Boards: 🛠️ Frequently used in electronic training kits and prototype boards due to robust handling and standard 2V forward voltage characteristics.
- Urban Lighting & Decoration: ✨ Implemented in decorative light strings and city beautification projects requiring warm yellow light points.

📦 Package, Dimensions & Assembly Notes
- Package Type: F5 Round (Standard 5mm Diffused).
- Dimensions: The total length is approximately 18mm with a bulb diameter of 5.5mm. The lead spacing is designed for standard 2.54mm pitched perfboards or PCBs.
- Moisture Sensitivity: 🌧️ MSL Level 2. Components should be used within 3 months of opening the moisture-proof anti-static foil bag to prevent performance degradation.
- Assembly Guidelines: Ensure the soldering point is > 2.0mm from the base of the epoxy body to prevent thermal damage to the internal die bond. Manual welding should be limited to 3 seconds at 300°C.
🚚 Sourcing & Supply Considerations
- Consistency & Binning: 🔍 When sourcing for mass production, verify the binning codes (Voltage N12-7 to N12-9 and Brightness A5-A7) to match your BOM's circuit driver design.
- Supply Chain Risk: The XL-502UYD utilizes a standard footprint, but optical color consistency varies by bin batch. Procurement managers should lock down the wavelength bin (HY03-HY06) early to avoid visual color shifts in the final product.
- Verification: Confirm packaging is EIA standard with anti-static protection to prevent ESD damage during logistics.
❓ Frequently Asked Questions
Q: What is the forward voltage requirement for the XL-502UYD?
A: The typical forward voltage is 2.0V at a standard test current of 20mA. The minimum is 1.8V, and the maximum is 2.4V. Designers should ensure their current limiting resistors can handle the variation up to 2.4V to prevent current spikes.
Q: Can this LED be used in outdoor environments?
A: While the operating temperature range (-20°C to +85°C) allows for use in varying climates, the yellow epoxy resin is generally rated for indoor use or enclosed outdoor fixtures. Prolonged exposure to UV sunlight may degrade the epoxy colloid over time.
Q: What does "MSL Level 2" mean for handling?
A: Moisture Sensitivity Level 2 means the components must be soldered within 1 year of factory sealing. Once the moisture-proof bag is opened, they should be assembled within 168 hours (1 week) if the ambient humidity is < 60% RH (30°C), or baked before use if stored longer.
Q: How is the brightness sorted for this model?
A: XINGLIGHT sorts brightness into three codes: A5 (400-500 mcd), A6 (500-700 mcd), and A7 (700-900 mcd). For critical applications requiring uniform panel brightness, specifying a single brightness bin (e.g., only A6) is recommended.
Q: Is the XL-502UYD RoHS compliant?
A: Yes, the datasheet explicitly states that this is an environmental protection product meeting ROHS requirements, ensuring it is free from hazardous substances like lead, mercury, and cadmium.
