TLUG2401-AS12 Equivalent & Substitute Parts

Part Overview

The TLUG2401-AS12 is a green diffused LED with 1.8mm lens diameter, designed for through-hole mounting in indication applications. Manufactured by Vishay Semiconductor Opto Division, this component operates at 2.4V forward voltage with 12mcd brightness rating and 568nm dominant wavelength. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLUG2401-AS12 is determined by strict alignment of the following critical parameters:

• Color specification: Green
• Wavelength - Dominant: 568nm
• Millicandela Rating: 12mcd
• Lens Size: 1.80mm Dia
• Lens Transparency: Diffused
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole
• Package / Case: Radial

The WP4060GD from Kingbright meets all substitution criteria. While forward voltage differs slightly (2.2V vs 2.4V) and viewing angle is wider (70° vs 40°), these variations remain within acceptable tolerance for indication applications and do not prevent functional equivalence. The substitute maintains identical color, wavelength, brightness rating, lens geometry, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The WP4060GD is the qualified substitute for TLUG2401-AS12 applications. Selection is supported by:

• Identical color, wavelength, and brightness specifications ensure optical performance equivalence
• Matching lens geometry and diffused transparency maintain visual characteristics
• Through-hole radial package compatibility enables direct board-level substitution
• ROHS3 compliance on both components satisfies regulatory requirements
• Active product status of WP4060GD ensures long-term availability and supply chain continuity, addressing the obsolescence of the original TLUG2401-AS12

The 0.2V reduction in forward voltage (2.2V vs 2.4V) and increased viewing angle (70° vs 40°) represent minor parameter variations that do not compromise functional equivalence in indication applications. Maximum height difference of 0.5mm (4.10mm vs 3.60mm) requires verification against specific PCB clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can WP4060GD directly replace TLUG2401-AS12 without circuit modification?

A: Yes. Both components share identical color, wavelength, brightness rating, lens size, and mounting type. The 0.2V forward voltage difference is within typical circuit tolerance for LED indication circuits. Verify that your current-limiting resistor accommodates the lower forward voltage of the substitute.

Q: What is the impact of the 70° viewing angle on WP4060GD compared to the 40° angle of TLUG2401-AS12?

A: The wider viewing angle of WP4060GD provides greater visibility across a broader angular range. For applications requiring narrow-angle indication, this represents an improvement in visibility. No circuit modification is required.

Q: Are there any height clearance concerns with the WP4060GD?

A: WP4060GD has a maximum height of 4.10mm compared to 3.60mm for TLUG2401-AS12. Verify available PCB clearance above the component to ensure no interference with overlying components or enclosure geometry.

Q: Do both components meet the same compliance standards?

A: Yes. Both TLUG2401-AS12 and WP4060GD are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: Why is WP4060GD recommended over other green LEDs?

A: WP4060GD is the only substitute that maintains all critical parameters: identical 568nm wavelength, 12mcd brightness, 1.80mm lens diameter, diffused transparency, and round domed lens style. These specifications are essential for optical and mechanical equivalence.
