Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLUG2400-MS12Z is determined by the following critical parameters:

• Color specification: Green (568nm dominant wavelength)
• Lens configuration: 1.8mm diffused lens with round domed top
• Mounting technology: Through-hole radial lead package
• Electrical characteristics: Forward voltage range and test current compatibility
• Mechanical fit: Physical dimensions and height constraints
• Compliance requirements: RoHS3 certification

The WP4060GD from Kingbright qualifies as a substitute based on matching these core parameters. Both components share identical lens size, color specification, dominant wavelength, mounting type, and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The WP4060GD is qualified as a direct substitute for the TLUG2400-MS12Z based on the following engineering criteria:

Both components maintain ROHS3 compliance and share identical optical and mechanical specifications for lens size, color, wavelength, and through-hole radial mounting configuration. The WP4060GD is currently in active production status, ensuring supply chain continuity for applications previously designed around the obsolete TLUG2400-MS12Z.

The forward voltage difference of 0.2V (2.4V vs 2.2V) falls within standard LED tolerance ranges and does not preclude substitution in typical indicator circuit applications. The maximum height difference of 0.5mm (3.60mm vs 4.10mm) must be verified against specific PCB layout and enclosure clearance constraints.

The WP4060GD provides enhanced performance characteristics with 12mcd brightness and 70° viewing angle compared to the original 10mcd and 40° specifications, representing functional improvements for indicator visibility without introducing compatibility issues.

Frequently Asked Questions (FAQ)

Q: Can the WP4060GD be used as a direct replacement for the TLUG2400-MS12Z in existing PCB designs?

A: Yes, the WP4060GD is mechanically and electrically compatible for through-hole mounting in existing TLUG2400-MS12Z footprints. The identical lens size (1.8mm), radial lead configuration, and physical dimensions (3.30mm L x 2.40mm W) ensure direct substitution. Verify that the 0.5mm maximum height difference (4.10mm vs 3.60mm) does not conflict with enclosure or component clearance requirements.

Q: What is the impact of the 0.2V forward voltage difference between these components?

A: The forward voltage difference of 0.2V (TLUG2400-MS12Z at 2.4V vs WP4060GD at 2.2V) is within standard LED manufacturing tolerances. In typical indicator applications with current-limiting resistors, this difference does not require circuit redesign. Verify compatibility with your specific power supply and current-limiting circuit design.

Q: Does the higher brightness rating of the WP4060GD (12mcd vs 10mcd) affect compatibility?

A: The increased brightness is a performance enhancement that does not compromise compatibility. The WP4060GD will provide improved indicator visibility. If your application requires specific brightness levels, verify that the 12mcd rating meets or exceeds your design requirements.

Q: Are there any compliance or certification differences between these components?

A: Both components are ROHS3 compliant. The WP4060GD carries REACH Unaffected status and EAR99 ECCN classification. The TLUG2400-MS12Z is classified as obsolete. For applications requiring specific regulatory documentation, verify that the WP4060GD certifications meet your compliance requirements.

Q: What is the significance of the wider viewing angle in the WP4060GD (70° vs 40°)?

A: The WP4060GD provides a 70° viewing angle compared to the original 40° specification. This wider angle improves indicator visibility from off-axis positions, representing a functional enhancement for most indicator applications without introducing compatibility concerns.
