Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLUO2401 are qualified based on the following critical parameters:

• Color and Wavelength: Red spectrum LEDs with dominant wavelength in the 619-623nm range
• Lens Transparency: Diffused lens type for uniform light distribution
• Electrical Characteristics: Forward voltage of 2V and test current of 10mA
• Mounting Configuration: Through-hole radial package with 3.60mm maximum height
• Regulatory Compliance: ROHS3 compliance and active product status

The LTL-709E from Lite-On Inc. meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TLUO2401 and LTL-709E are active products with ROHS3 compliance, ensuring regulatory alignment for current manufacturing standards. The primary distinction between these parts is the millicandela rating: the LTL-709E provides 12.6mcd compared to the TLUO2401's 5mcd, resulting in higher luminous intensity. Both components share identical forward voltage (2V), test current (10mA), and physical dimensions (3.60mm height), confirming mechanical and electrical interchangeability in through-hole applications. The wavelength specifications remain within the red spectrum range, with the LTL-709E positioned at 623nm dominant wavelength versus the TLUO2401 at 619nm. Selection between these parts should be based on the required brightness level for the specific indication application.

Frequently Asked Questions (FAQ)

Q: Can the LTL-709E directly replace the TLUO2401 in existing PCB designs?

A: Yes. Both parts share identical forward voltage (2V), test current (10mA), radial through-hole package configuration, and maximum height (3.60mm). No circuit modifications are required for mechanical or electrical compatibility.

Q: What is the significance of the millicandela rating difference?

A: The LTL-709E operates at 12.6mcd while the TLUO2401 operates at 5mcd. This difference represents luminous intensity output. The LTL-709E will produce a brighter indication. Selection depends on the brightness requirement of the application.

Q: Are there viewing angle differences between these parts?

A: The TLUO2401 has a 40° viewing angle while the LTL-709E has a 38° viewing angle. This 2° difference is negligible for most indication applications and does not affect substitution suitability.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the TLUO2401 and LTL-709E are ROHS3 compliant and maintain active product status, confirming compliance with current environmental and manufacturing standards.

Q: What is the wavelength difference between these LEDs?

A: The TLUO2401 has a dominant wavelength of 619nm while the LTL-709E is 623nm. Both fall within the red spectrum range and are visually indistinguishable in typical indication applications.
