📌 Product Overview
The XINGLIGHT XL-DZT502UYD1 is a standard 5mm (T-1 3/4) radial leaded LED designed for general-purpose indication. It features a diffused, yellow epoxy lens with a yellow colloid, providing a peak wavelength of 588nm. 💡
This device is optimized for low-voltage DC drive systems (typical VF 2.2V @ 20mA) and is structured for high-volume assembly with Moisture Sensitivity Level (MSL) 2 compliance. It targets standard board-level indication where cost-effectiveness and reliable optical consistency are critical.
🔌 Typical Applications
Based on the device's 35-degree viewing angle and robust operating temperature range, key use cases include:
- Consumer Electronics: Status indicators (power, signal) for home appliances and digital devices.
- Automotive Sub-Assemblies: Non-critical interior dashboard lighting and control indicators.
- Industrial & Instruction: Electronic teaching equipment, clock displays, and traffic signal indicators.
- Instrumentation: Medical and beauty equipment panel indicators requiring ROHS compliance.

📦 Package, Dimensions & Assembly Notes
- Package Type: F5 (5mm Diameter) T-1 3/4 Radial Lead.
- Dimensions: 11.3mm (Total Length) x 15.0mm (Lead Spread) x 10.3mm (Height). Tolerances are ±0.25mm unless noted.
- Lens: Yellow diffused epoxy for wide light distribution.
- Packaging: EIA standard compliant, bulk supplied in moisture-proof and anti-electrostatic foil bags.
- Assembly: 🚨 Ensure solder points maintain a distance >2.0mm from the epoxy body to prevent thermal damage during reflow or wave soldering.
🚛 Sourcing & Supply Considerations
- Binning Management: Verify specific Bin codes (e.g., A7 for brightness) if visual uniformity is required across the PCB.
- Moisture Control: As an MSL 2 component, lead-free storage must be controlled. If the original moisture-proof bag is open (>3 months), baking or nitrogen dry storage is recommended before reflow.
- Compliance: 🌱 Confirm ROHS status is current for specific shipment batches to meet environmental directives.
❓ Frequently Asked Questions
Q: What is the forward voltage range for this yellow LED?
A: The forward voltage (VF) ranges from a minimum of 1.8V to a maximum of 2.4V at the rated current of 20mA. Typical operating voltage is 2.2V.
Q: How long can the XL-DZT502UYD1 be stored before use?
A: The datasheet recommends usage within 3 months if kept in the original packaging at <30°C and <70% RH. For longer storage, use a dry cabinet or nitrogen environment.
Q: What are the soldering temperature limits for automated assembly?
A: For wave soldering (reflow), the limit is 240°C for ≤6 seconds. For manual welding, the limit is 300°C for 3 seconds. Do not solder within 2mm of the plastic body.
Q: How is the brightness graded for this model?
A: Brightness is binned via codes A4 through A9. For example, A6 covers 500–700 mcd, while A9 covers 1200–1500 mcd. Selecting the correct bin ensures consistent panel illumination.
Q: Is this LED suitable for automotive exterior lighting?
A: No. While listed under "Automotive Electronics," this is a standard 5mm indicator best suited for interior panels or dashboard indicators. Exterior lighting typically requires higher power and stricter compliance.
