TLUG2400-MS21Z Equivalent & Substitute Parts

Part Overview

The TLUG2400-MS21Z is a green diffused LED indicator manufactured by Vishay Semiconductor Opto Division, designed for through-hole mounting applications. This component features a 1.8mm lens diameter with a domed top configuration and operates at a forward voltage of 2.4V with a test current of 20mA. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLUG2400-MS21Z is determined by the following critical parameters:

• Color and Wavelength: Green emission at 568nm dominant wavelength (565nm peak)
• Lens Configuration: 1.8mm diameter diffused lens with round domed top
• Electrical Characteristics: Forward voltage of 2.4V and test current of 20mA
• Mounting Technology: Through-hole radial lead configuration
• Compliance: ROHS3 compliance requirement

The identified substitute WP4060GD from Kingbright meets these core substitution criteria while maintaining functional equivalence for green LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

The WP4060GD serves as the primary substitute for the obsolete TLUG2400-MS21Z. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute exhibits a lower forward voltage (2.2V versus 2.4V) and higher luminous intensity (12mcd versus 10mcd), with an expanded viewing angle of 70° compared to the original 40°. These characteristics position the WP4060GD as a functionally compatible replacement for green LED indication circuits requiring through-hole radial mounting with diffused lens optics.

Frequently Asked Questions (FAQ)

Q: Can the WP4060GD directly replace the TLUG2400-MS21Z in existing PCB designs?

A: Yes. Both components share identical lens diameter (1.8mm), lens style (round domed top), mounting type (through-hole radial), and wavelength characteristics (568nm dominant). The radial lead configuration and physical dimensions (3.30mm L x 2.40mm W) are compatible with existing through-hole footprints.

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

A: The WP4060GD operates at 2.2V versus the original 2.4V. This lower forward voltage reduces power dissipation in series resistor circuits and may require recalculation of current-limiting resistor values to maintain the 20mA test current specification.

Q: How does the increased viewing angle affect circuit performance?

A: The WP4060GD provides a 70° viewing angle compared to the original 40°. This wider angle increases light visibility across a broader spatial range, which is beneficial for indicator applications but does not compromise compatibility with designs requiring the narrower original specification.

Q: Are there compliance or certification differences between the two parts?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: What is the availability status of each part?

A: The TLUG2400-MS21Z is obsolete with limited inventory (1123 pcs). The WP4060GD is active production with significantly higher availability (36823 pcs), ensuring supply chain continuity.
