Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT325AD5Y6T0SC is determined by alignment across the following critical parameters:

Color and Color Temperature: Both the main part and substitute must operate at white neutral 4000K to maintain consistent chromaticity in lighting applications.

Electrical Characteristics: Forward voltage, test current, and maximum current ratings must be compatible with existing circuit designs. Lumens per watt efficiency and flux output at 25°C establish performance equivalence.

Optical Properties: Color Rendering Index (CRI) and viewing angle define the quality and distribution of emitted light.

Mechanical and Thermal Properties: Package type, mounting configuration, size dimensions, and thermal resistance determine physical and thermal compatibility with PCB layouts and thermal management systems.

Compliance and Status: RoHS compliance and product status (active versus obsolete) ensure regulatory adherence and supply chain viability.

The substitute part L130-4090003000W21 (Lumileds LUXEON 3030 2D) shares the core functional parameters of neutral white 4000K operation while introducing variations in package footprint, electrical ratings, and thermal characteristics that require engineering evaluation for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPMWHT325AD5Y6T0SC is classified as obsolete, while the L130-4090003000W21 maintains active product status with established supply chain availability. Active status ensures continued manufacturing support and component availability for production requirements.

Compliance Alignment: Both parts satisfy RoHS requirements. The substitute part carries ROHS3 compliance, representing current regulatory standards. The main part meets RoHS Compliant specification.

Electrical Performance: The substitute part operates at 6.1V forward voltage compared to 5.8V for the main part, representing a 0.3V increase. Test current increases from 100mA to 120mA. Maximum current rating increases from 200mA to 240mA. These variations require circuit design verification to confirm compatibility with existing power supply and current-limiting configurations.

Optical Performance: The substitute part delivers 92 lumens at 25°C versus 85 lumens for the main part, representing approximately 8% higher flux output. The substitute achieves 126 lm/W efficiency compared to 147 lm/W for the main part. Color Rendering Index improves from 80 to 90 in the substitute part. Viewing angle decreases marginally from 120° to 116°.

Thermal Characteristics: The substitute part exhibits superior thermal performance with 12°C/W thermal resistance compared to 15°C/W for the main part, enabling more efficient heat dissipation.

Package Footprint: The main part uses a 3.60mm x 2.30mm 2-SMD package, while the substitute employs a 3.00mm x 3.00mm 1212 (3030 Metric) package. This dimensional difference requires PCB layout modification and revalidation of mechanical fit and thermal interface.

Moisture Sensitivity: The main part specifies MSL 2A (4 Weeks), while the substitute specifies MSL 3 (168 Hours). This difference affects storage, handling, and reflow process requirements.

Frequently Asked Questions (FAQ)

Q: Can the L130-4090003000W21 directly replace the SPMWHT325AD5Y6T0SC without circuit modification?

A: Direct replacement requires circuit design review. The substitute part operates at 6.1V forward voltage compared to 5.8V for the main part, and test current increases from 100mA to 120mA. Existing current-limiting resistors and power supply configurations must be verified for compatibility with these electrical parameter changes.

Q: What are the key differences in package footprint between these parts?

A: The SPMWHT325AD5Y6T0SC uses a 3.60mm x 2.30mm 2-SMD package (3623 supplier designation), while the L130-4090003000W21 uses a 3.00mm x 3.00mm 1212 (3030 Metric) package. PCB layout modifications are required to accommodate the different footprint dimensions and pad configurations.

Q: How do the optical characteristics compare?

A: Both parts operate at 4000K neutral white color temperature. The substitute part delivers 92 lumens compared to 85 lumens for the main part at their respective test currents. The substitute achieves a higher Color Rendering Index of 90 versus 80 for the main part. Viewing angle decreases slightly from 120° to 116° in the substitute.

Q: What is the significance of the thermal resistance difference?

A: The substitute part exhibits 12°C/W thermal resistance compared to 15°C/W for the main part. Lower thermal resistance indicates more efficient heat transfer from the LED junction to the PCB, enabling better thermal management in high-power or thermally constrained applications.

Q: Are there moisture sensitivity considerations for component handling?

A: The main part specifies MSL 2A (4 Weeks), while the substitute specifies MSL 3 (168 Hours). The substitute part requires more frequent reflow processing or desiccant storage to prevent moisture absorption. Handling procedures and reflow process parameters must align with the substitute part's moisture sensitivity classification.

Q: Why is the main part classified as obsolete?

A: The SPMWHT325AD5Y6T0SC is designated as obsolete by Samsung Semiconductor, indicating discontinued manufacturing and limited future availability. The L130-4090003000W21 maintains active product status, ensuring ongoing supply chain support and manufacturing continuity.

Q: What compliance certifications apply to both parts?

A: Both parts satisfy RoHS requirements. The main part carries RoHS Compliant certification, while the substitute part carries ROHS3 Compliant certification, representing current regulatory standards for hazardous substance restrictions in electrical and electronic equipment.
