Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSL-LX100133XRC/3 is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Lens size: 10.00mm diameter
• Lens style: Round with domed top
• Mounting type: Through hole radial configuration
• Supplier device package: T-10mm

Optical Characteristics:

• Color: Red
• Lens transparency: Clear (colorless)
• Peak wavelength range: 636nm to 660nm (red spectrum)

Electrical Parameters:

• Forward voltage (Vf): 1.7V to 2V range
• Test current: 20mA
• Brightness rating: Comparable millicandela output

Regulatory & Environmental:

• RoHS3 compliance
• REACH unaffected status
• MSL rating: 1 (Unlimited)

The SSL-LX100133SIC meets all substitution criteria as an active product from the same manufacturer within the same base product family (SSL-LX100133), maintaining mechanical and optical compatibility while offering improved availability.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX100133SIC is the direct substitute for the obsolete SSL-LX100133XRC/3. Both components are manufactured by Lumex Opto/Components Inc. and share identical mechanical form factors, mounting configurations, and regulatory compliance certifications.

The substitute part maintains ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements. The MSL rating of 1 (Unlimited) is consistent across both parts, indicating no moisture sensitivity constraints during storage or handling.

The primary electrical difference is the forward voltage specification: the substitute operates at 2V compared to the original 1.7V. This 0.3V increase falls within typical design tolerances for LED indication circuits and does not preclude direct substitution in standard applications. The peak wavelength shift from 660nm to 636nm represents a minor variation within the red spectrum and maintains visual compatibility for indication purposes.

The substitute part is currently in active production with substantial inventory availability (18,938 pieces), ensuring reliable long-term sourcing compared to the obsolete status of the original component.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX100133SIC be used as a direct replacement for SSL-LX100133XRC/3?

A: Yes. Both components share identical mechanical dimensions (10mm T-10mm through-hole radial package), lens configuration (round domed clear), color (red), and test current (20mA). The substitute is manufactured by the same supplier and maintains all required regulatory certifications.

Q: What is the impact of the 0.3V forward voltage difference?

A: The SSL-LX100133SIC operates at 2V compared to the original 1.7V. This difference is accommodated by standard LED circuit designs that typically include current-limiting resistors. The voltage increase does not affect mechanical compatibility or optical performance.

Q: Does the wavelength change from 660nm to 636nm affect visual appearance?

A: Both wavelengths fall within the red spectrum. The 24nm shift represents a minor variation that maintains visual compatibility for indication applications. Both components produce red light suitable for standard LED indication purposes.

Q: Are there any packaging differences between these parts?

A: The main part was supplied in tape and reel packaging (indicated by the -3 suffix). The substitute is supplied in bulk packaging. Both use identical T-10mm through-hole radial form factors and are compatible with standard PCB assembly processes.

Q: What is the availability status of each part?

A: The SSL-LX100133XRC/3 is obsolete with 658 pieces in current stock. The SSL-LX100133SIC is active in production with 18,938 pieces available, providing superior long-term sourcing reliability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SSL-LX100133XRC/3 and SSL-LX100133SIC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the MSL rating for these components?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard storage and handling procedures are sufficient without special environmental controls.
