Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SPMWHT5492D5SGTMS0 is determined by alignment of the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must operate at neutral white 4000K to maintain consistent color output in lighting applications.

Luminous Flux Performance: The substitute must deliver equivalent or superior luminous flux at its specified test current. The main part produces 49lm at 20mA test current; the substitute L130-4080002011001 delivers 49lm at 120mA test current, demonstrating comparable photometric performance within the specified range.

Color Rendering Index (CRI): Both parts maintain CRI of 80, ensuring equivalent color fidelity for general lighting applications.

Mounting Type and Surface Mount Compatibility: Both parts are surface mount LEDs suitable for automated assembly processes.

Regulatory Compliance: Both parts meet RoHS requirements and carry EAR99 ECCN classification, ensuring compliance with export and environmental regulations.

Electrical Operating Characteristics: While forward voltage and test current differ between parts (18.5V/20mA versus 3.05V/120mA), these differences reflect distinct circuit design topologies. The substitute operates at lower voltage with higher current, requiring appropriate driver circuit modification but maintaining equivalent luminous output.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPMWHT5492D5SGTMS0 is classified as obsolete. The substitute part L130-4080002011001 from Lumileds carries active product status, ensuring ongoing availability, technical support, and manufacturing continuity.

Compliance and Certification: Both parts satisfy RoHS requirements. The substitute achieves ROHS3 compliance, representing current regulatory standards. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining export and tariff compliance.

Photometric Equivalence: Both parts deliver 49lm luminous flux with 80 CRI at neutral white 4000K. The substitute achieves 134 lm/W efficiency compared to 132 lm/W for the main part, representing a marginal efficiency improvement.

Electrical and Thermal Characteristics: The substitute operates at significantly lower forward voltage (3.05V versus 18.5V) and higher test current (120mA versus 20mA). This requires driver circuit redesign but is standard practice in LED substitution workflows. The substitute exhibits slightly higher thermal resistance (13°C/W versus 10°C/W), requiring thermal management evaluation in high-power applications.

Package and Form Factor: The substitute uses a smaller 3020 package (3.00 × 2.00mm) compared to the 5630 package (5.00 × 3.00mm) of the main part. This requires PCB layout modification and may impact thermal dissipation in constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the L130-4080002011001 directly replace the SPMWHT5492D5SGTMS0 without circuit modification?

A: No. The substitute operates at 3.05V forward voltage with 120mA test current, compared to 18.5V and 20mA for the main part. Driver circuit redesign is required to accommodate the different electrical characteristics. Direct pin-for-pin substitution is not possible.

Q: Are the color and brightness characteristics identical between these parts?

A: Both parts deliver 49lm luminous flux at neutral white 4000K with 80 CRI. Photometric performance is equivalent. The substitute achieves marginally higher efficiency (134 lm/W versus 132 lm/W).

Q: What are the package compatibility implications?

A: The main part uses a 5630 package (5.00 × 3.00mm); the substitute uses a 3020 package (3.00 × 2.00mm). PCB footprint redesign is required. The smaller substitute package may improve space efficiency but requires thermal management reassessment.

Q: Does the substitute meet the same regulatory requirements?

A: Both parts carry EAR99 ECCN and 8541.41.0000 HTSUS classifications. The substitute achieves ROHS3 compliance versus RoHS compliance for the main part, representing alignment with current environmental standards.

Q: What is the significance of the different thermal resistance values?

A: The main part exhibits 10°C/W thermal resistance; the substitute exhibits 13°C/W. In applications with high ambient temperatures or limited thermal dissipation, the substitute may reach higher junction temperatures. Thermal design review is required for high-power or thermally constrained applications.

Q: Is the substitute part currently available?

A: Yes. The L130-4080002011001 carries active product status with 16,176 pieces in stock, compared to the obsolete status of the main part with 870 pieces remaining.

Q: What is the viewing angle difference impact?

A: The main part specifies 115° viewing angle. The substitute does not specify viewing angle in the provided data. Application-specific beam pattern requirements must be evaluated independently.
