Key Parameters

Substitute Part Grouping Explanation

The WP4060GD from Kingbright qualifies as a direct substitute based on the following critical parameters:

• Color Match: Both components emit green light at 568nm dominant wavelength and 565nm peak wavelength
• Lens Configuration: Identical 1.8mm diameter diffused lens with round domed top styling
• Brightness Rating: Both rated at 12mcd millicandela output
• Mounting Type: Both utilize through-hole radial lead configuration
• Electrical Compatibility: Forward voltage differential of 0.2V (2.4V vs 2.2V) and identical 20mA test current remain within acceptable LED indicator tolerances
• Viewing Angle: WP4060GD provides 70° viewing angle compared to 40° on original part, offering improved visibility
• Compliance: Both components maintain ROHS3 compliance and REACH unaffected status

Parameter Comparison

Engineering Selection Recommendations

The WP4060GD represents the appropriate substitute for TLUG2401-AS12Z applications. The original component's obsolete status combined with active availability of the Kingbright equivalent ensures supply chain continuity. Both components maintain identical ROHS3 and REACH compliance certifications, satisfying regulatory requirements for new designs and legacy system replacements.

The 0.2V forward voltage reduction in the WP4060GD (2.2V vs 2.4V) requires circuit verification to confirm compatibility with existing current-limiting resistor values. The increased viewing angle (70° vs 40°) and maximum height differential (4.10mm vs 3.60mm) must be evaluated against specific PCB layout and mechanical enclosure constraints.

Frequently Asked Questions (FAQ)

Q: Can WP4060GD directly replace TLUG2401-AS12Z without circuit modifications?

A: Direct mechanical and optical substitution is possible. However, the 0.2V forward voltage difference requires circuit analysis to confirm the existing current-limiting resistor maintains appropriate LED current at the lower voltage. Verify that the increased maximum height (4.10mm vs 3.60mm) does not conflict with mechanical clearances.

Q: What is the significance of the viewing angle difference between these components?

A: The TLUG2401-AS12Z provides 40° viewing angle while WP4060GD offers 70°. This difference affects the angular range over which the LED maintains specified brightness. The wider viewing angle of the substitute may improve visibility in applications requiring observation from multiple angles.

Q: Are there any compliance or certification concerns with this substitution?

A: Both components maintain ROHS3 compliance and REACH unaffected status. No additional compliance barriers exist for this substitution in regulated applications.

Q: How do the physical dimensions compare?

A: Lateral dimensions are identical (3.30mm L x 2.40mm W). The maximum height increases from 3.60mm to 4.10mm on the substitute. Verify clearance in confined spaces or applications with tight vertical constraints.

Q: Is the 12mcd brightness rating identical between both components?

A: Yes, both components are rated at 12mcd millicandela output, ensuring equivalent optical performance in indicator applications.
