Substitution Logic:

The substitute parts are grouped into two series categories:

LM561B Plus Series (Same Series): Parts SPMWHT541MP5WAVSS5, SPMWHT541MP5WAV0S5, SPMWHT541MP5WAVNS5, SPMWHT541MP5WAVKS5, and SPMWHT541MP5WAVMS5 maintain identical electrical performance (2.95V Vf, 177 lm/W, 180mA max current, 15°C/W thermal resistance) and are direct functional equivalents. These differ only in packaging tape configuration or RoHS certification status.
LM561C Series (Cross-Series Alternative): Parts SPMWHT541ML5XAV0S5, SPMWHT541ML5XAVKS5, and SPMWHT541ML5XAVMS5 represent an upgraded series with improved efficiency (190 lm/W vs. 177 lm/W), lower 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). These maintain identical flux output, color, CCT, viewing angle, and package specifications.

All substitute parts share the same base product number (SPMWHT541), confirming design family compatibility.

Engineering Selection Recommendations

For Direct Replacement (Same Series, Active Status):

Select from LM561B Plus active alternatives when maintaining identical electrical performance is required. SPMWHT541MP5WAVMS5 offers the highest inventory availability (26,898 pcs) with ROHS3 compliance and is suitable for new production orders. SPMWHT541MP5WAVSS5 provides ROHS3 certification with slightly improved thermal resistance (14°C/W vs. 15°C/W). SPMWHT541MP5WAV0S5, SPMWHT541MP5WAVNS5, and SPMWHT541MP5WAVKS5 maintain standard RoHS compliance with consistent 15°C/W thermal resistance and adequate inventory levels.

For Performance Enhancement (LM561C Series, Active Status):

The LM561C series substitutes deliver measurable improvements: 7.3% higher efficiency (190 lm/W vs. 177 lm/W), 20% lower forward voltage (2.75V vs. 2.95V), 11% higher maximum current rating (200mA vs. 180mA), and 20% superior thermal resistance (12°C/W vs. 15°C/W). These upgrades reduce power dissipation and thermal load while maintaining identical flux output and color specifications. SPMWHT541ML5XAVMS5 provides the highest inventory (10,671 pcs) with ROHS3 compliance. SPMWHT541ML5XAVKS5 and SPMWHT541ML5XAV0S5 offer RoHS compliance with lower inventory levels.

Compliance Considerations:

All substitute parts maintain RoHS compliance (either standard RoHS or ROHS3). ROHS3-certified variants (SPMWHT541MP5WAVSS5, SPMWHT541MP5WAVMS5, SPMWHT541ML5XAVMS5) are recommended for applications requiring enhanced regulatory documentation. All parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming trade compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVUS5 be directly replaced with LM561C series parts?

A: Yes. LM561C series substitutes (SPMWHT541ML5XAV0S5, SPMWHT541ML5XAVKS5, SPMWHT541ML5XAVMS5) are functionally compatible. They maintain identical flux output (34 lm), color (White, Warm 3000K), viewing angle (120°), and package specifications (5630, 4-SMD, Flat Leads). The lower forward voltage (2.75V vs. 2.95V) and higher efficiency (190 lm/W vs. 177 lm/W) represent performance improvements, not incompatibilities.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications confirm lead-free and hazardous substance restrictions. ROHS3 represents an updated compliance standard. Parts marked ROHS3 (SPMWHT541MP5WAVSS5, SPMWHT541MP5WAVMS5, SPMWHT541ML5XAVMS5) are suitable for applications requiring current regulatory alignment.

Q: Does the 0.20V forward voltage difference between LM561B Plus (2.95V) and LM561C (2.75V) affect circuit design?

A: The voltage difference must be evaluated within the context of the LED driver circuit. If the driver is current-regulated (constant current source), the voltage difference has minimal impact on LED performance. If the driver is voltage-regulated, circuit adjustment may be necessary. Consult the LED driver specifications for compatibility confirmation.

Q: Why do some part numbers have different thermal resistance values (14°C/W vs. 15°C/W)?

A: Thermal resistance variations reflect manufacturing process improvements or package material refinements within the same 5630 form factor. Lower thermal resistance (14°C/W in SPMWHT541MP5WAVSS5) indicates improved heat dissipation characteristics, beneficial for high-current or thermally constrained applications.

Q: Are all substitute parts available in the same tape and reel packaging?

A: Yes. All parts listed are supplied in Tape & Reel (TR) packaging with identical Moisture Sensitivity Level (MSL 2A, 4 Weeks). Packaging format is consistent across all substitutes, ensuring compatibility with automated assembly equipment.

Q: Which substitute part offers the best inventory availability?

A: SPMWHT541MP5WAVMS5 (LM561B Plus, Active) provides the highest inventory at 26,898 pcs. For LM561C series, SPMWHT541ML5XAVMS5 offers 10,671 pcs. Both are suitable for volume production requirements.

Q: Can SPMWHT541MP5WAVUS5 be used in new designs?

A: No. The part is marked "Not For New Designs," indicating end-of-life status. Select from active alternatives: LM561B Plus series (SPMWHT541MP5WAVSS5, SPMWHT541MP5WAV0S5, SPMWHT541MP5WAVNS5, SPMWHT541MP5WAVKS5, SPMWHT541MP5WAVMS5) or LM561C series (SPMWHT541ML5XAV0S5, SPMWHT541ML5XAVKS5, SPMWHT541ML5XAVMS5) for new product development.
