LTL-313SJ Equivalent & Substitute Parts

Part Overview

The LTL-313SJ is a dual-color LED indicator manufactured by Lite-On Inc., featuring integrated green and red light-emitting elements in a single 5mm diffused lens package. This component is designed for visual indication applications requiring both color states. The part is currently classified as obsolete, making identification of compatible substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTL-313SJ is determined by the following critical parameters that must remain consistent:

• Color Configuration: Both parts must provide green and red light emission
• Wavelength Specifications: Dominant wavelengths must match (569nm green, 638nm red) and peak wavelengths must match (565nm green, 660nm red)
• Electrical Characteristics: Forward voltage (2.1V green, 1.8V red) and test current (20mA) must be identical
• Optical Properties: Lens size (5mm, T-1 3/4), lens style (round with domed top), lens transparency (diffused), and viewing angle (60°) must be maintained
• Regulatory Compliance: ECCN and HTSUS classifications must align

The LTL-293SJW qualifies as a direct substitute based on these parameters. Both components share identical electrical specifications, wavelength characteristics, optical properties, and regulatory classifications. The primary difference is the mounting type (through-hole versus unspecified for the original) and higher luminous intensity ratings in the substitute part.

Engineering Selection Recommendations

The LTL-293SJW is the manufacturer-recommended substitute for the obsolete LTL-313SJ. Selection of this substitute is supported by the following factors:

• Electrical Compatibility: Identical forward voltage and test current specifications ensure direct circuit compatibility without modification to drive circuitry
• Optical Compatibility: Matching wavelength specifications (dominant and peak) and viewing angle maintain color consistency and visibility characteristics in the application
• Physical Compatibility: Identical lens size, style, and transparency preserve mechanical fit and optical performance in existing mechanical assemblies
• Regulatory Alignment: Both components share identical ECCN and HTSUS classifications, maintaining compliance status
• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity
• Compliance Status: The LTL-293SJW is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements

The increased millicandela ratings (40mcd green, 90mcd red versus 13mcd green, 38mcd red) represent an enhancement in luminous intensity, providing improved visibility without introducing compatibility issues.

Frequently Asked Questions (FAQ)

Q: Can the LTL-293SJW be used as a direct replacement for the LTL-313SJ in existing designs?

A: Yes. The LTL-293SJW meets all critical electrical and optical parameters required for substitution. Identical forward voltage, test current, wavelength specifications, and viewing angle ensure functional compatibility. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The LTL-313SJ is obsolete, while the LTL-293SJW is an active product in current production. The substitute features higher luminous intensity ratings and is specified for through-hole mounting. Both share identical electrical and optical characteristics.

Q: Are there any compliance or regulatory differences between the parts?

A: No. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The LTL-293SJW additionally carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Q: Does the higher millicandela rating of the LTL-293SJW affect circuit design?

A: No. The increased luminous intensity does not affect electrical circuit parameters. Forward voltage and test current remain identical, so existing drive circuitry requires no modification.

Q: What mounting considerations apply to the LTL-293SJW?

A: The LTL-293SJW is specified for through-hole mounting with radial configuration. Verify that the PCB design accommodates through-hole mounting before implementation. The 8.60mm maximum height should be confirmed against mechanical clearance requirements.

Q: Is the LTL-293SJW available in the same packaging as the LTL-313SJ?

A: The LTL-293SJW is supplied in bulk packaging, whereas the original part packaging is not specified. Confirm packaging requirements with your procurement process.
