📌 Product Overview
The XL-504RGBC is a discrete, 5mm radial LED component featuring a full-color Red, Green, and Blue (RGB) chip matrix encased in a transparent water-clear colloid. 💡 It is engineered to deliver high-brightness output suitable for illumination tasks requiring vivid color mixing and wide viewing angles. This component is specifically designed for through-hole PCB assembly where robust mechanical coupling and optical intensity are prioritized over miniature footprint size.
🎯 Typical Applications
Based on its optical characteristics and robust 5mm package, the XL-504RGBC is optimized for the following scenarios:
- Channel Lettering & Signage: Ideal for large-format illuminated signs where consistent color mixing is critical.
- Electronic Advertising: Used in lightboxes and information displays requiring long operational life.
- Status Indication: Suitable for industrial equipment panels needing clear, multi-colored status signals.
- Decorative Lighting: Implemented in arts, crafts, and ambient lighting fixtures.
- Specialty Wearables: Integrated into costumes or special clothing requiring flexible, low-voltage illumination.
⚡ Key Technical Specifications
The XL-504RGBC exhibits distinct electrical characteristics for each color die, requiring specific drive considerations for circuit design. 💡 The typical optical performance is measured at a forward current of 20mA.

📦 Package, Dimensions & Assembly Notes
The component utilizes a standard F5 radial leadform with an epoxy lens diameter of 5.0mm and a total length of 29mm. ⚙️ The exterior dimensions are approximately 5.9mm (W) x 29mm (L). For assembly and soldering, the following physical constraints must be observed to prevent mechanical stress on the die:
- Lead Forming: Leads must be clamped and bent at a point ≥ 2.0mm from the epoxy body to prevent cracking the colloid or damaging the internal bond wires.
- Welding/Soldering:
- Manual Soldering: Max 300°C for ≤ 3 seconds.
- Wave Soldering: Max 240°C for ≤ 6 seconds.
- Cleaning: Use ethanol only; avoid chemicals like Trichloroethylene or Acetone which may damage the transparent lens.
🚚 Sourcing & Supply Considerations
When integrating the XL-504RGOC into mass production, verify the following supply chain factors to prevent line stoppages:
- Packaging Standard: Components are shipped in moisture-proof and anti-electrostatic foil bags, compliant with EIA standards.
- Environmental Compliance: Verify current RoHS certificates; the datasheet indicates compliance, but batch-specific documentation may be required for export markets.
- Storage Management: As an MSL 2 component, it can be stored at <30°C / <70% RH for up to 3 months before baking is required.
❓ Frequently Asked Questions
Q: What is the forward voltage requirement for the Green and Blue chips?
A: While the datasheet lists a range of 2.0V - 5.0V, Red typically drops ~2.0V. 💡 Designers should anticipate a forward voltage of approximately 3.0V to 3.4V for the Green and Blue channels at 20mA to ensure sufficient headroom in the driver circuit.
Q: Can this LED be used in outdoor sign applications?
A: Yes, the epoxy colloid is designed for general lighting and signage. However, for outdoor environments, the LED must be protected from direct UV exposure and water ingress by the outer housing of the sign, as the standard epoxy may yellow over time under harsh UV.
Q: What precautions are necessary for wave soldering?
A: The soldering point must be > 2.0mm from the bottom of the colloid. 👇 Do not exceed 240°C or 6 seconds dwell time. Mechanical stress on the leads must be minimized immediately after soldering while the joint cools.
Q: How should I handle the component if it has been opened for more than 3 months?
A: According to the precautions, if the LED is removed from its moisture-proof bag for more than 3 months, or if the storage environment exceeds 30°C/70% RH, it should be baked in a dry box or with desiccant/nitrogen purge before mounting to prevent "popcorning" damage during reflow.
Q: Is the XL-504RGBC compatible with automatic insertion machines?
A: Yes, the "EIA standard packaging" and defined pitch suggest suitability for automatic lead forming and insertion equipment, provided the tooling accommodates the 5.9mm width and standard lead spacing.
