Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WAVNS0 is determined by the following critical parameters:

Primary Substitution Criteria:

• Color and CCT: White, Warm 3000K (exact match required)
• CRI: 80 (exact match required)
• Viewing Angle: 120° (exact match required)
• Test Current: 65mA (exact match required)
• Package / Case: 4-SMD, Flat Leads 5630 (exact match required)
• Physical Dimensions: 5.00mm × 3.00mm × 0.80mm max (exact match required)
• Maximum Current Rating: 180mA (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters (Allowable Variation):

• Forward Voltage (Vf): 2.75V to 2.95V (within typical LED forward voltage tolerance)
• Flux Output: 31–35 lm range at 65mA (within specified tolerance band)
• Lumens/Watt: 172–185 lm/W (efficiency variation acceptable within series)
• Thermal Resistance: 12–15°C/W (package thermal performance variation)

Series Compatibility: The LM561B Plus series (main part) is substitutable with the LM561C series (substitute parts) based on identical electrical performance at rated test conditions, matching package geometry, and equivalent optical characteristics. Both series maintain the same 3000K color temperature, 80 CRI, and 120° viewing angle specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: SPMWHT541MP5WAVMS5

The SPMWHT541MP5WAVMS5 is the direct equivalent within the LM561B Plus series. This part maintains identical electrical specifications (2.95V forward voltage, 172–177 lm/W efficiency range) and is currently in Active product status. It carries ROHS3 compliance certification, representing the latest regulatory standard. This part is the preferred choice for direct replacement in existing designs without circuit modification.

Secondary Recommendations: SPMWHT541ML5XAV0S0, SPMWHT541ML5XAVKS0, SPMWHT541ML5XAVMS0

These three parts represent the LM561C series equivalent. All three maintain Active product status and RoHS compliance. The LM561C series offers improved thermal performance (12°C/W versus 15°C/W) and higher luminous efficiency (181–185 lm/W versus 172–177 lm/W). Forward voltage varies within the 2.75V to 2.8V range, which is acceptable for most constant-current LED driver applications. These parts are suitable for new designs and provide superior thermal characteristics for high-density applications.

Substitution Feasibility:

All listed substitute parts are electrically and mechanically compatible with the SPMWHT541MP5WAVNS0. The primary differentiator is forward voltage tolerance and thermal resistance. Applications using constant-current drivers (typical for LED lighting) will experience no functional difference. Applications using constant-voltage supplies may require circuit verification due to forward voltage variation.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS5 be used as a direct replacement for SPMWHT541MP5WAVNS0?

A: Yes. Both parts are LM561B Plus series components with identical forward voltage (2.95V), test current (65mA), flux output (33 lm nominal), and package geometry (5630, 4-SMD). The primary difference is product status: SPMWHT541MP5WAVMS5 is Active while SPMWHT541MP5WAVNS0 is Not For New Designs. No circuit modification is required.

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

A: Both series deliver identical optical performance at rated test conditions (33 lm at 65mA, 3000K, 80 CRI, 120° viewing angle). The LM561C series offers improved thermal resistance (12°C/W versus 15°C/W) and higher luminous efficiency (181–185 lm/W versus 172–177 lm/W). Forward voltage in the LM561C series ranges from 2.75V to 2.8V, compared to 2.95V in the LM561B Plus series.

Q: Are the LM561C substitutes suitable for constant-voltage applications?

A: LM561C parts (SPMWHT541ML5XAV0S0, SPMWHT541ML5XAVKS0, SPMWHT541ML5XAVMS0) operate at 2.75V to 2.8V forward voltage, which is 0.15V to 0.20V lower than the LM561B Plus 2.95V specification. In constant-voltage applications, this voltage difference will result in slightly higher current draw through the current-limiting resistor. Circuit verification is required to confirm the design remains within acceptable operating parameters.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. All substitute parts share identical package geometry (5630, 4-SMD, Flat Leads), physical dimensions (5.00mm × 3.00mm × 0.80mm max height), and mounting type (Surface Mount). No PCB layout modification is necessary. Parts are mechanically and electrically interchangeable at the board level.

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

A: The LM561C series exhibits lower thermal resistance (12°C/W) compared to LM561B Plus (15°C/W). This means the LM561C junction temperature will be approximately 3°C lower at identical ambient conditions and power dissipation. For high-density LED arrays or applications with elevated ambient temperatures, the LM561C series provides improved thermal performance and extended operational margin.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed carry RoHS compliance certification. SPMWHT541MP5WAVMS5 carries ROHS3 certification (latest standard), while SPMWHT541ML5XAV0S0, SPMWHT541ML5XAVKS0, and SPMWHT541ML5XAVMS0 carry RoHS certification. Both certifications meet current regulatory requirements for electronic component manufacturing.

Q: What is the MSL rating and why is it important?

A: All parts carry MSL 2A (4 Weeks) rating. This indicates the component can be exposed to ambient conditions of 30°C / 85% relative humidity for up to 4 weeks before soldering without requiring baking. After 4 weeks of exposure, the component must be baked at 125°C for 24 hours before assembly. Proper moisture handling is critical to prevent solder joint defects and component reliability issues.

Q: Which substitute part offers the best efficiency?

A: The LM561C series parts (SPMWHT541ML5XAV0S0 and SPMWHT541ML5XAVKS0) deliver the highest luminous efficiency at 185 lm/W, compared to 172 lm/W for the original SPMWHT541MP5WAVNS0 and 177 lm/W for SPMWHT541MP5WAVMS5. This represents a 7.6% efficiency improvement over the original part.
