Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LX15IC-TR is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Forward voltage (Vf): 2V nominal
• Test current: 20mA
• Peak wavelength: 635nm (red spectrum)
• Luminous intensity: 10mcd

Mechanical Compatibility Parameters:

• Mounting type: Surface Mount
• Package family: SOT-23-3 variant
• Lens color: Colorless
• Lens transparency: Clear
• Viewing angle: 140°

Regulatory & Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99
• HTSUS: 8541.41.0000

The substitute part SML-LX15IC-TR meets all critical electrical and mechanical parameters while maintaining full regulatory compliance. Packaging configuration differences (Tape & Reel vs. standard packaging) do not affect functional substitution.

Engineering Selection Recommendations

Primary Recommendation: SML-LX15IC-TR

The SML-LX15IC-TR is the direct functional equivalent for SSL-LX15IC-TR applications. Selection rationale:

1. Product Status Alignment: SML-LX15IC-TR maintains active product status, ensuring long-term availability and supply chain continuity. SSL-LX15IC-TR obsolete status creates procurement risk for new designs and ongoing production.

2. Electrical Parameter Equivalence: All critical electrical specifications are identical—2V forward voltage, 20mA test current, 10mcd luminous intensity, and 635nm peak wavelength. Circuit-level performance is functionally equivalent.

3. Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status. No additional compliance burden or design modification required.

4. Mechanical Compatibility: SOT-23-3 package family compatibility ensures PCB footprint and reflow process compatibility. Dimensional variations (lens size and height) fall within acceptable mechanical tolerances for standard surface mount assembly.

5. Moisture Sensitivity: SML-LX15IC-TR MSL rating of 3 (168 hours) provides superior moisture protection compared to SSL-LX15IC-TR MSL rating of 4 (72 hours), reducing handling and storage risk.

6. Supply Availability: SML-LX15IC-TR inventory of 30,216 pieces ensures immediate procurement availability versus SSL-LX15IC-TR limited stock of 3,540 pieces.

Frequently Asked Questions (FAQ)

Q: Can SML-LX15IC-TR be used as a direct replacement for SSL-LX15IC-TR in existing designs?

A: Yes. SML-LX15IC-TR is functionally equivalent across all critical electrical parameters (voltage, current, wavelength, luminous intensity) and maintains identical package family classification (SOT-23-3). PCB footprint compatibility is confirmed. No circuit redesign is required.

Q: What are the physical dimension differences between these parts?

A: SSL-LX15IC-TR lens dimensions are 3.00mm L x 1.50mm W with 1.05mm maximum height. SML-LX15IC-TR lens dimensions are 3.00mm L x 3.00mm W with 1.00mm maximum height. Both dimensions are within standard surface mount assembly tolerances and do not affect electrical performance or circuit functionality.

Q: Are there any compliance or regulatory differences?

A: No. Both parts maintain identical ROHS3 compliance and REACH unaffected status. ECCN and HTSUS classifications are identical. No additional compliance documentation or design modification is required for substitution.

Q: What is the significance of the different Moisture Sensitivity Level (MSL) ratings?

A: SML-LX15IC-TR MSL 3 (168 hours) provides extended moisture protection compared to SSL-LX15IC-TR MSL 4 (72 hours). This represents improved handling and storage characteristics. Standard surface mount assembly processes accommodate both MSL ratings without additional process modification.

Q: Why is SSL-LX15IC-TR classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. SML-LX15IC-TR active status ensures ongoing availability, technical support, and supply chain reliability for current and future applications.

Q: Are the electrical specifications identical between these parts?

A: Yes. Forward voltage (2V), test current (20mA), peak wavelength (635nm), luminous intensity (10mcd), and viewing angle (140°) are identical. Electrical circuit behavior is functionally equivalent.

Q: What packaging format is SML-LX15IC-TR supplied in?

A: SML-LX15IC-TR is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly operations. SSL-LX15IC-TR standard packaging is compatible with equivalent reel-based handling systems.
