Key Parameters

Substitute Part Grouping Explanation

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

• Color and Wavelength: Green 568nm dominant wavelength ensures consistent optical appearance and system compatibility
• Lens Configuration: 1.8mm diffused round domed lens maintains mechanical fit and optical characteristics
• Mounting Type: Through-hole radial lead configuration ensures PCB compatibility
• Electrical Characteristics: Forward voltage and test current parameters define circuit compatibility
• Physical Dimensions: 3.30mm L x 2.40mm W footprint ensures mechanical interchangeability
• Compliance: ROHS3 compliance required for regulatory alignment

The WP4060GD from Kingbright meets these substitution criteria while offering improved availability as an active product.

Parameter Comparison

Engineering Selection Recommendations

The WP4060GD is a direct functional substitute for the TLUG2400-ASZ based on the following engineering criteria:

Mechanical Compatibility: Identical lens size (1.8mm), lens style (round domed), and package dimensions (3.30mm L x 2.40mm W) ensure direct PCB mounting compatibility without layout modifications.

Optical Compatibility: Matching dominant wavelength (568nm) and diffused lens transparency guarantee consistent visual appearance and system performance in indication applications.

Electrical Compatibility: Forward voltage of 2.2V versus 2.4V represents a 0.2V variance within acceptable circuit design tolerances for LED indication circuits. Both components operate at 20mA test current.

Regulatory Compliance: Both components maintain ROHS3 compliance, ensuring alignment with current environmental and regulatory requirements.

Product Availability: The WP4060GD is an active product with substantial inventory availability (36,823 pcs), providing supply chain continuity compared to the obsolete TLUG2400-ASZ.

Frequently Asked Questions (FAQ)

Q: Can the WP4060GD directly replace the TLUG2400-ASZ without circuit modifications?

A: Yes. The WP4060GD is mechanically and optically compatible with identical lens dimensions, wavelength, and mounting configuration. The 0.2V forward voltage difference (2.2V vs 2.4V) is within standard LED circuit design tolerances and does not require circuit redesign for typical indication applications.

Q: What are the key differences between these two parts?

A: The WP4060GD offers higher brightness (12mcd vs 10mcd) and a wider viewing angle (70° vs 40°). Forward voltage is slightly lower (2.2V vs 2.4V). These differences represent improvements in optical performance while maintaining full mechanical and electrical compatibility.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the TLUG2400-ASZ and WP4060GD are ROHS3 compliant, meeting current environmental and regulatory standards.

Q: Why is the TLUG2400-ASZ obsolete?

A: The TLUG2400-ASZ has been discontinued by Vishay Semiconductor Opto Division. The WP4060GD from Kingbright provides equivalent functionality with active product status and reliable supply chain availability.

Q: What is the significance of the 1.8mm lens size?

A: The 1.8mm lens size is a critical mechanical parameter that determines PCB mounting compatibility and visual appearance in system designs. The WP4060GD maintains this specification, ensuring direct interchangeability.

Q: Does the higher brightness of the WP4060GD affect circuit design?

A: No. Both components operate at the same 20mA test current. The higher brightness (12mcd vs 10mcd) of the WP4060GD is an inherent characteristic of the LED die and does not require circuit modifications. This represents an improvement in optical performance.
