📌 Product Overview
The XL-A524SURUGC is a discrete 5mm (F5) bi-color LED component from XINGLIGHT, integrating high-brightness Red and Green emitters into a common cathode package. 💡 Designed with a transparent water-clear colloid, this device provides high luminous intensity (up to 14,000 mcd for Green) suitable for status indication and aesthetic lighting. It serves as a versatile solution for electronic designs requiring multi-state visual feedback in a compact radial leaded form factor.
Target applications range from industrial backlights to household consumer goods. The component is engineered to support low-voltage DC drive circuits, offering fast response times and reduced power consumption compared to traditional filament indicators. 👇 Design focus should be placed on the differing forward voltages between the Red (1.8V-2.4V) and Green (2.8V-3.4V) chips to ensure proper current limiting in shared circuitry.
🔍 Typical Applications
Based on the optical characteristics and F5 dimensions, the XL-A524SURUGC is optimized for the following use cases:
- 📊 Backlight Modules: Ideal for LCD or switch indicator backlights where color variation is used to signal distinct modes (e.g., Standby vs. Active).
- 🚗 Automotive Interior: Suitable for dashboard illumination and cabin control buttons, provided the operating temperature range (-20°C to +85°C) is respected.
- 🚦 Signal Indication: Effective for industrial equipment status lights, power supply LEDs, and fault indicators requiring clear visibility.
- 🏠 Smart Home Devices: Used in appliance panels and IoT hubs for network pairing status or operational feedback.
- 💡 General Lighting: applicable to decorative light strings or small-area accent lighting.
⚡ Key Technical Specifications
💡 The following table outlines the electro-optical performance under standard test conditions (Ta=25°C).
| Parameter | Symbol | Red (Min / Typ / Max) | Green (Min / Typ / Max) | Unit | Conditions |

| Dominant Wavelength | λd | 630 / - / 640 | 515 / - / 530 | nm | IF = 20mA |
| Peak Wavelength | λp | - / 640 / - | - / 525 / - | nm | IF = 20mA |
| Forward Voltage | VF | 1.8 / - / 2.4 | 2.8 / - / 3.4 | V | IF = 20mA |

🔒 The MSL (Moisture Sensitivity Level) is rated at Level 2. Floor life is limited; ensure proper baking if components have been exposed to ambient humidity for extended periods prior to reflow to prevent "popcorning" or package delamination.
📦 Package, Dimensions & Assembly Notes
The XL-A524SURUGC utilizes a standard F5 radial package with a rectangular base design, distinct from standard round 3mm or 5mm LEDs.
- Dimensions: The datasheet specifies appearance dimensions of 5.8mm (W) x 5.0mm (L) x 8.7mm (H). 👇 Verify the PCB footprint hole spacing to match the 2.54mm (100mil) standard pitch if applicable, though this specific model suggests a wider base potentially for snap-in mounting.
- Colloid: The water-clear transparent epoxy allows for maximum light transmission but is susceptible to UV yellowing over long periods in high-UV environments.
- Assembly: Standard wave soldering profiles apply, but the lead length must maintain a minimum distance of 2.0mm from the colloid bottom to the solder joint to prevent thermal damage to the epoxy dome.
🚢 Sourcing & Supply Considerations
When integrating the XL-A524SURUGC into BOMs, consider the following supply chain factors:
- Binning Codes: The datasheet details specific binning codes (e.g., A5/A6 for Red intensity, C1/C2/C3 for Green intensity, and N12/N13 for voltage). ✨ Request specific bins if color uniformity or forward voltage matching is critical for your power budget.
- Packaging: The device adheres to EIA standard packaging standards, facilitating compatibility with most auto-insertion equipment.
- Reliability Validation: The device has undergone testing for 1000hrs operating life and humidity resistance (85°C/85% RH), making it suitable for standard consumer electronics but requiring validation for harsh industrial environments.
- Compliance: The product is RoHS compliant, meeting standard environmental safety requirements.
❓ FAQ
Q: What is the forward voltage difference between the Red and Green chips?
A: The Red chip has a forward voltage range of 1.8V to 2.4V, while the Green chip requires 2.8V to 3.4V. If driving them in parallel with a single resistor, the lower voltage Red chip will hog the current; separate current-limiting resistors are strongly recommended for each color.
Q: Can this LED be used in outdoor environments?
A: While the operating temperature range is -20°C to +85°C, the water-clear epoxy colloid is not inherently UV-resistant. Prolonged exposure to direct sunlight may cause the epoxy to yellow or become brittle over time, reducing light output.
Q: What does "Common Cathode" mean for this model?
A: "Common Cathode" indicates that the negative cathode terminals of both the Red and Green diodes are internally connected to a single lead. The other two leads act as independent Anodes (one for Red, one for Green).
Q: What are the soldering limits to prevent damage?
A: The absolute maximum soldering temperature is 300°C for manual soldering (max 3s) or 240°C for wave soldering (max 6s). Crucially, the solder point must be at least 2.0mm away from the bottom of the LED body to avoid thermal shock to the epoxy.
Q: How is brightness categorized for this component?
A: Brightness is sorted by Binning Codes. For the Green component, codes C1 through C3 indicate intensities ranging from 8,000 mcd to 14,000 mcd. For Red, codes A5 and A6 cover 400 to 700 mcd. Verify your required bin code when placing orders to ensure consistency.
