Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the SSL-LX5093OT is based on the following allowed parameters that define functional and mechanical compatibility:

Mechanical Compatibility Parameters:

• Lens size: 5mm, T-1 3/4
• Lens style: Round with Domed Top
• Mounting type: Through Hole
• Package type: Radial
• Maximum height: 8.60mm

Electrical Compatibility Parameters:

• Forward voltage (Vf): 2V to 2.1V range
• Test current: 20mA
• Viewing angle: 30°

Regulatory & Environmental Parameters:

• RoHS3 Compliance
• MSL Level 1 (Unlimited)
• REACH Unaffected status

The SSL-LX5093YT qualifies as a substitute part because it maintains identical mechanical dimensions, mounting configuration, and regulatory compliance. The primary difference is color (yellow vs. orange) and associated wavelength shift (585nm vs. 630nm), with a minor forward voltage increase (2.1V vs. 2V) and reduced brightness (40mcd vs. 130mcd). These differences are acceptable in applications where color indication function takes precedence over brightness matching.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Function): The SSL-LX5093YT serves as a functional substitute for the SSL-LX5093OT in applications where orange indication can be replaced with yellow indication. Both components share identical mechanical form factors, mounting configurations, and regulatory compliance certifications (ROHS3, REACH Unaffected, MSL Level 1). The SSL-LX5093YT is currently in active production status, providing superior supply chain availability compared to the obsolete SSL-LX5093OT.

Electrical Considerations: The SSL-LX5093YT operates at 2.1V forward voltage versus 2V for the SSL-LX5093OT, representing a 0.1V increase. This difference is within typical LED circuit design tolerances and does not require circuit redesign in standard current-limiting applications. Both components operate at identical 20mA test current.

Brightness Consideration: The SSL-LX5093YT delivers 40mcd compared to 130mcd for the SSL-LX5093OT. Applications requiring the original brightness level should evaluate alternative orange LEDs within the Lumex SSL-LX5093 series or consider brightness compensation through circuit design adjustments.

Compliance & Regulatory: Both components maintain identical RoHS3 compliance, REACH unaffected status, and MSL Level 1 rating, ensuring no regulatory or environmental qualification barriers to substitution.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX5093YT directly replace the SSL-LX5093OT in existing PCB designs?

A: Yes, from a mechanical and electrical standpoint. Both components feature identical 5mm T-1 3/4 through-hole radial packages with 8.60mm maximum height. Pin spacing and mounting hole requirements are identical. The 0.1V forward voltage difference (2V vs. 2.1V) is accommodated by standard LED current-limiting circuits. The primary design consideration is color change from orange to yellow.

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

A: The SSL-LX5093OT delivers 130mcd at 20mA test current, while the SSL-LX5093YT delivers 40mcd at the same test current. This represents a 69% reduction in brightness. Applications with strict brightness requirements should evaluate this difference against system specifications.

Q: Are there any regulatory or compliance differences?

A: No. Both the SSL-LX5093OT and SSL-LX5093YT maintain identical ROHS3 compliance, REACH unaffected status, and MSL Level 1 (unlimited moisture sensitivity) ratings. No additional qualification or testing is required from a regulatory perspective.

Q: Why is the SSL-LX5093YT recommended despite being a different color?

A: The SSL-LX5093OT is classified as obsolete, creating supply chain risk. The SSL-LX5093YT is in active production with 12,279 pieces in stock versus 753 pieces for the obsolete SSL-LX5093OT. In applications where color indication function is flexible or where yellow can serve the same system role as orange, the SSL-LX5093YT provides superior availability and long-term supply security.

Q: What viewing angle do both components provide?

A: Both the SSL-LX5093OT and SSL-LX5093YT provide a 30° viewing angle, ensuring identical light distribution characteristics and visibility performance in the application.

Q: Are there any circuit modifications required to use the SSL-LX5093YT instead of the SSL-LX5093OT?

A: No circuit modifications are required. The 0.1V forward voltage difference is negligible in standard LED current-limiting designs. Existing resistor values and circuit topologies remain valid. If brightness compensation is desired due to the 40mcd vs. 130mcd difference, current-limiting resistor values can be adjusted, but this is optional based on application requirements.
