Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LX15IGC-TR is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Dual-color LED configuration (Green and Red)
• Forward voltage specifications: 2.1V Green, 2V Red
• Test current rating: 20mA for both colors
• Millicandela output: 10mcd Green, 10mcd Red
• Peak wavelengths: 565nm Green, 635nm Red
• Viewing angle: 140°
• Surface mount technology
• SOT-23-3 package family compatibility
• RoHS3 and REACH compliance status

The substitute part SML-LX15IGC-TR meets all critical electrical parameters and maintains package compatibility within the SOT-23-3 family. Both parts are manufactured by Lumex Opto/Components Inc., ensuring consistent design and performance characteristics.

Engineering Selection Recommendations

The SML-LX15IGC-TR is the direct substitute for the obsolete SSL-LX15IGC-TR based on the following engineering criteria:

Product Status Alignment: The SML-LX15IGC-TR maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete SSL-LX15IGC-TR.

Electrical Compatibility: Both parts share identical forward voltage specifications (2.1V Green, 2V Red), test current ratings (20mA), millicandela outputs (10mcd), and peak wavelengths (565nm Green, 635nm Red). These parameters ensure direct functional equivalence in circuit applications.

Package Compatibility: Both components utilize SOT-23-3 package technology with surface mount configuration. The SML-LX15IGC-TR offers a marginal height reduction (1.00mm vs. 1.05mm maximum), which presents no compatibility issues for standard PCB layouts.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for industrial and commercial applications.

Moisture Handling: The SML-LX15IGC-TR provides improved moisture sensitivity characteristics (MSL 3 vs. MSL 4), offering enhanced reliability during storage and handling operations.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX15IGC-TR directly replace the SSL-LX15IGC-TR in existing designs?

A: Yes. The SML-LX15IGC-TR provides direct electrical and mechanical substitution. Identical forward voltage, test current, brightness, wavelength, and viewing angle specifications ensure functional equivalence. Both components use SOT-23-3 surface mount packaging with compatible PCB footprints.

Q: What are the key differences between these two parts?

A: The primary differences are product status (SSL-LX15IGC-TR is obsolete; SML-LX15IGC-TR is active), packaging format (SSL-LX15IGC-TR uses standard packaging; SML-LX15IGC-TR uses Tape & Reel), maximum height (1.05mm vs. 1.00mm), and moisture sensitivity level (MSL 4 vs. MSL 3). These differences do not affect electrical performance or circuit compatibility.

Q: Are there any circuit design modifications required when switching from SSL-LX15IGC-TR to SML-LX15IGC-TR?

A: No circuit modifications are required. Both parts operate at identical forward voltages and test currents. PCB layout remains compatible due to matching SOT-23-3 package specifications and nearly identical physical dimensions.

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

A: The SML-LX15IGC-TR has MSL 3 (168 hours) compared to MSL 4 (72 hours) for the SSL-LX15IGC-TR. This indicates the SML-LX15IGC-TR can tolerate longer exposure to moisture before soldering without performance degradation, providing improved handling flexibility in manufacturing environments.

Q: Is the SML-LX15IGC-TR available in higher volume quantities?

A: Yes. The SML-LX15IGC-TR is supplied in Tape & Reel packaging format with significantly higher inventory availability (64,095 pcs), compared to the SSL-LX15IGC-TR (935 pcs). This format supports automated assembly processes and provides better supply chain continuity.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the SSL-LX15IGC-TR and SML-LX15IGC-TR are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory requirements for industrial applications.
