The SPMWHT541MP5WAQ0S5, SPMWHT541MP5WAQKS5, SPMWHT541MP5WAQMS5, and SPMWHT541MP5WAQSS5 are direct functional equivalents to the SPMWHT541MP5WAQUS5. All maintain identical 5700K color temperature, 36 lm flux output, 120° viewing angle, and 4-SMD 5630 package configuration. These parts carry Active product status, making them suitable for new designs. All variants are RoHS Compliant with 2A MSL rating. The SPMWHT541MP5WAQSS5 offers improved thermal resistance at 14°C/W compared to the main part's 15°C/W, with ROHS3 Compliant certification.

For 5700K CCT with Enhanced Efficiency (LM561C Series):

The SPMWHT541ML5XAQ0S5, SPMWHT541ML5XAQKS5, and SPMWHT541ML5XAQMS5 provide 5700K color temperature with improved efficiency at 201 lm/W versus 188 lm/W. These LM561C series parts feature reduced forward voltage (2.75V vs. 2.95V), higher maximum current rating (200mA vs. 180mA), and superior thermal resistance (12°C/W vs. 15°C/W). All maintain identical flux output, CRI, viewing angle, and mechanical dimensions. All carry Active product status and RoHS Compliant certification.

For 5000K CCT Applications (Alternative Color Temperature):

The SPMWHT541ML5XAR0S5, SPMWHT541ML5XARKS5, and SPMWHT541ML5XARMS5 provide substitution for applications requiring 5000K color temperature instead of 5700K. These LM561C series parts maintain all other critical parameters: 36 lm flux, 65 mA test current, 120° viewing angle, 4-SMD 5630 package, and identical mechanical dimensions. Thermal resistance is 12°C/W. The SPMWHT541ML5XAR0S5 carries ROHS3 Compliant certification; others are RoHS Compliant. All have Active product status.

Compliance and Certification:

All substitute parts maintain RoHS compliance (either RoHS or ROHS3 variant), 2A MSL rating, EAR99 ECCN classification, and 8541.41.0000 HTSUS code. Substitution does not introduce compliance risk.

Frequently Asked Questions (FAQ)

Q: Can I substitute SPMWHT541MP5WAQUS5 with LM561C series parts?

A: Yes. LM561C series parts (SPMWHT541ML5XAQ0S5, SPMWHT541ML5XAQKS5, SPMWHT541ML5XAQMS5) are functionally equivalent for 5700K applications. They maintain identical flux output (36 lm), CRI (80), viewing angle (120°), and mechanical fit (5630 package, 5.00mm × 3.00mm, 0.80mm height). LM561C variants offer improved efficiency (201 lm/W vs. 188 lm/W) and thermal performance (12°C/W vs. 15°C/W). Forward voltage differs (2.75V vs. 2.95V) and maximum current is higher (200mA vs. 180mA), but both are within acceptable operating ranges for equivalent applications.

Q: What is the difference between SPMWHT541MP5WAQUS5 and SPMWHT541MP5WAQ0S5?

A: Both are LM561B Plus series parts with identical electrical and optical specifications: 5700K CCT, 36 lm flux, 2.95V Vf, 65 mA test current, 188 lm/W efficiency, 80 CRI, and 120° viewing angle. The primary difference is product status: SPMWHT541MP5WAQUS5 is "Not For New Designs," while SPMWHT541MP5WAQ0S5 is "Active." Mechanical and thermal characteristics are identical (15°C/W thermal resistance, 5630 package, 0.80mm height). Both are RoHS Compliant with 2A MSL.

Q: Can I use a 5000K part as a substitute for a 5700K requirement?

A: No. The SPMWHT541ML5XAR0S5, SPMWHT541ML5XARKS5, and SPMWHT541ML5XARMS5 are specified for 5000K applications and are not interchangeable with 5700K requirements. Color temperature is a primary substitution criterion and cannot be varied. Use only parts specified for 5700K CCT when 5700K is required.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the 4-SMD, Flat Leads package configuration with 5630 supplier device package designation. Mechanical dimensions are identical: 0.197" L × 0.118" W (5.00mm × 3.00mm) with 0.031" (0.80mm) maximum seated height. All are surface mount components with identical footprint compatibility.

Q: What is the thermal resistance difference between LM561B Plus and LM561C series?

A: LM561B Plus parts (SPMWHT541MP5WAQ0S5, SPMWHT541MP5WAQKS5, SPMWHT541MP5WAQMS5, SPMWHT541MP5WAQSS5) have thermal resistance of 15°C/W (14°C/W for SPMWHT541MP5WAQSS5). LM561C parts (SPMWHT541ML5XAQ0S5, SPMWHT541ML5XAQKS5, SPMWHT541ML5XAQMS5, SPMWHT541ML5XAR0S5, SPMWHT541ML5XARKS5, SPMWHT541ML5XARMS5) have thermal resistance of 12°C/W. The LM561C series provides superior thermal performance, reducing junction temperature rise by approximately 3°C/W under identical power dissipation conditions.

Q: Do all substitute parts have the same RoHS compliance status?

A: Most substitute parts are RoHS Compliant. However, SPMWHT541ML5XAR0S5 and SPMWHT541MP5WAQSS5 carry ROHS3 Compliant certification, which represents an updated compliance standard. All parts meet RoHS requirements; ROHS3 is a more recent certification variant. Both statuses are acceptable for component selection.

Q: What is the maximum current rating difference?

A: SPMWHT541MP5WAQUS5 and all LM561B Plus variants have a maximum current rating of 180 mA. LM561C series parts have a maximum current rating of 200 mA. This difference reflects improved current handling capability in the LM561C design. Both ratings are specified for the same 65 mA test current condition.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. All substitute parts carry MSL 2A (4 Weeks) rating, identical to SPMWHT541MP5WAQUS5. This indicates equivalent moisture sensitivity and identical storage and handling requirements.
