Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WAV0SD is determined by strict alignment across the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must be White, Warm 3000K to maintain identical color output in end-use applications.

Series Compatibility: The LM561B series designation ensures consistent electrical and photometric characteristics across the product family.

Electrical Parameters: Forward voltage (2.95V typical), test current (65mA), and maximum current ratings must remain within the specified ranges to ensure safe operation in existing circuit designs.

Photometric Output: Flux output at 25°C and 65mA test current must fall within the acceptable range (31–35lm) to maintain luminous intensity consistency.

Package and Mounting: The 5630 package format with 4-SMD flat lead configuration and surface mount mounting type must be preserved for PCB compatibility and assembly process alignment.

Thermal and Mechanical Specifications: Viewing angle (120°), thermal resistance, and physical dimensions must support equivalent thermal management and optical performance.

Compliance: RoHS and MSL ratings ensure environmental and handling compatibility with existing supply chain and manufacturing processes.

The SPMWHT541MP5WAVMS5 substitute part meets all these criteria while offering enhanced product status and improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPMWHT541MD5WAV0SD is designated "Not For New Designs," indicating Samsung has concluded active development and support for this specific model. The SPMWHT541MP5WAVMS5 carries "Active" product status, ensuring ongoing manufacturing support, supply chain availability, and compliance with current regulatory standards.

Compliance and Certification: Both parts maintain RoHS compliance. The substitute part achieves ROHS3 certification, representing alignment with the most current environmental compliance requirements. Both parts carry identical MSL ratings (2A, 4 Weeks), ensuring equivalent moisture handling and storage protocols.

Performance Characteristics: The substitute part delivers measurably improved efficiency (177 lm/W versus 172 lm/W) and higher maximum current rating (180mA versus 150mA), providing enhanced operational headroom. Thermal resistance is reduced (15°C/W versus 16°C/W), supporting improved heat dissipation. Physical height is reduced (0.80mm versus 0.90mm), offering minor PCB assembly advantages.

Electrical and Optical Equivalence: Forward voltage, test current, color temperature, CRI, and viewing angle remain identical. Flux output at test conditions (34lm) remains within the specified tolerance band (31–35lm), ensuring luminous intensity compatibility.

Package and Mechanical Compatibility: Both parts utilize the 5630 package format with identical footprint dimensions (5.00mm × 3.00mm). The substitute employs flat leads versus exposed pad configuration; both are compatible with standard 5630 PCB landing patterns and reflow assembly processes.

The SPMWHT541MP5WAVMS5 is a direct functional and electrical substitute suitable for production applications requiring the SPMWHT541MD5WAV0SD specification.

Frequently Asked Questions (FAQ)

Q: Can the SPMWHT541MP5WAVMS5 be used as a direct replacement for the SPMWHT541MD5WAV0SD in existing designs?

A: Yes. Both parts share identical color temperature (3000K), forward voltage (2.95V), test current (65mA), CRI (80), viewing angle (120°), and package footprint (5630, 5.00mm × 3.00mm). Flux output at test conditions (34lm for substitute versus 33lm for main part) remains within the specified tolerance band (31–35lm). The substitute is electrically and optically compatible with existing circuit designs.

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

A: The substitute part (SPMWHT541MP5WAVMS5) offers three measurable improvements: (1) higher efficiency (177 lm/W versus 172 lm/W), (2) higher maximum current rating (180mA versus 150mA), and (3) lower thermal resistance (15°C/W versus 16°C/W). The substitute also carries "Active" product status versus "Not For New Designs" for the main part. Physical height is reduced by 0.10mm (0.80mm versus 0.90mm). These differences represent performance enhancements without electrical or optical incompatibility.

Q: Are there any package or mounting differences that affect PCB assembly?

A: Both parts use the 5630 package format with identical footprint dimensions (5.00mm × 3.00mm) and surface mount mounting type. The main part features a flat lead exposed pad configuration, while the substitute uses flat leads. Both configurations are compatible with standard 5630 PCB landing patterns and reflow assembly processes. No PCB redesign is required.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The main part is RoHS Compliant. The substitute part is ROHS3 Compliant, representing alignment with the most current environmental compliance framework. Both parts carry identical MSL ratings (2A, 4 Weeks), ensuring equivalent moisture sensitivity handling and storage requirements.

Q: What is the significance of the "Not For New Designs" status on the main part?

A: This designation indicates Samsung has concluded active development and support for the SPMWHT541MD5WAV0SD. For ongoing production, maintenance, or new applications, the SPMWHT541MP5WAVMS5 (Active status) is the recommended source, ensuring continued supply chain availability, manufacturing support, and compliance with evolving regulatory standards.

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

A: Yes. Both parts deliver White, Warm 3000K color temperature with 80 CRI. Flux output at 25°C and 65mA test current is 33lm for the main part (31–35lm range) and 34lm for the substitute (33–35lm range). Both values fall within the acceptable tolerance band, ensuring equivalent luminous intensity and color rendering in end-use applications.

Q: Can the substitute part handle higher current levels than the main part?

A: Yes. The substitute part has a maximum current rating of 180mA compared to 150mA for the main part. This provides 30mA additional operational headroom. However, at the standard test current of 65mA, both parts operate identically. The higher maximum rating on the substitute offers design flexibility for applications requiring increased current capacity.
