| Soldering (Wave) | Tsol | 240 | °C | ≤ 6 seconds |
| Soldering (Manual) | Tsol | 300 | °C | ≤ 3 seconds |
🔒 Process Constraint: Soldering points must be kept > 2.0mm from the colloid base to prevent thermal damage to the epoxy.
📦 Package, Dimensions & Assembly Notes
The XL-502SURC utilizes the standard F5 cylindrical package.
- Dimensions: 5.5mm (Diameter) x 8.7mm (Length) x 18mm (Total Lead Length).
- Tolerance: ±0.50mm unless otherwise specified.
- Packaging: EIA standard compliance, typically shipped in bulk bags with anti-static protection.
- Assembly: The "Short Leg" design aids in compact PCB layouts but requires careful attention to lead forming to avoid mechanical stress on the epoxy body.
🛒 Sourcing & Supply Considerations
- Binning Consistency: Luminous intensity is binned (Codes B3-B6). Ensure consistent bin codes for uniformity in visible arrays.
- Supply Chain: Verify moisture sensitivity level (MSL 2) handling upon receipt to prevent performance drift.
- Cross-Reference: Useful as a drop-in replacement for standard F5 5mm red indicators in legacy BOMs.
❓ FAQ
Q: What is the typical forward voltage drop for this LED?
A: The typical forward voltage (VF) is 2.2V at a forward current of 20mA, with a maximum of 2.4V. Design drivers to accommodate up to 2.4V to ensure consistent brightness across batches.
Q: Can this component withstand lead-free soldering processes?
A: Yes. The datasheet specifies a maximum wave soldering temperature of 240°C for ≤6 seconds, which is compatible with standard lead-free profiles, provided the time limit is strictly observed.
Q: What does "MSL 2" mean for storage and handling?
A: MSL 2 (Moisture Sensitivity Level) indicates the component can be exposed to ambient air for up to one year (floor life) before baking is required. For storage >3 months beyond the seal date, use a dry cabinet or desiccant.
Q: How is the brightness sorted for this model?
A: Brightness is categorized into specific codes: B3 (2100-2500 mcd), B4 (2500-3000 mcd), B5 (3000-3500 mcd), and B6 (3500-4000 mcd). Procurement should specify the required bin code if visual uniformity is critical.
Q: What is the viewing angle?
A: The typical viewing angle (2Ø1/2) is 30 degrees. This makes it suitable for focused indicator lights rather than wide-area illumination.
Q: Is this LED RoHS compliant?
A: Yes, the XL-502SURC is explicitly listed as an environmentally friendly product meeting ROHS requirements.
