Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WAV0S3 is based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Color Temperature: 3000K warm white
• Forward Voltage: 2.95V (identical)
• Viewing Angle: 120°
• Package Type: 5630 (4-SMD)
• CRI: 80
• Mounting Type: Surface Mount
• Thermal Resistance: 16°C/W

Allowable Variation Parameters:

• Luminous Flux: Substitute may exceed baseline (30lm minimum acceptable)
• Maximum Current: Substitute may exceed baseline (150mA minimum acceptable)
• Lumens/Watt Efficiency: Substitute may exceed baseline
• Height: Substitute may be lower (0.90mm baseline; 0.80mm acceptable)
• Product Status: Active status preferred over obsolete

The SPMWHT541MP5WAV0S4 (LM561B Plus) qualifies as a direct substitute because it maintains all mandatory parameters while providing improved performance characteristics in allowable variation categories.

Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP5WAV0S4

The SPMWHT541MP5WAV0S4 is the qualified substitute for SPMWHT541MD5WAV0S3 based on the following engineering criteria:

1. Electrical Compatibility: Identical forward voltage (2.95V) and test current (65mA) ensure direct circuit compatibility without driver modification.

2. Optical Compatibility: Matching color temperature (3000K), CRI (80), and viewing angle (120°) maintain identical photometric performance in the application.

3. Mechanical Compatibility: Identical 5630 package footprint and dimensions (5.00mm × 3.00mm) enable direct PCB placement without layout changes. The reduced height (0.80mm vs. 0.90mm) presents no clearance issues.

4. Thermal Compatibility: Identical thermal resistance (16°C/W) maintains thermal design margins.

5. Regulatory Compliance: Both parts carry identical RoHS, REACH, ECCN, and HTSUS classifications, ensuring compliance continuity.

6. Product Status Advantage: The substitute is active production status, eliminating obsolescence risk and ensuring long-term availability.

7. Performance Enhancement: The substitute delivers improved luminous flux (32lm vs. 30lm) and efficiency (167 lm/W vs. 156 lm/W) within the same electrical operating point, providing design margin improvement.

8. Packaging Availability: The substitute is available in Tape & Reel packaging with 85,670 units in stock, supporting high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAV0S4 be used as a direct replacement in existing designs?

A: Yes. The substitute maintains identical forward voltage, test current, color temperature, CRI, viewing angle, and package footprint. No circuit modifications or PCB redesign are required.

Q: What is the difference between "Flat Lead Exposed Pad" and "Flat Leads"?

A: Both package variants use the same 5630 footprint and dimensions. The exposed pad variant provides enhanced thermal performance through direct substrate contact. The flat leads variant achieves identical thermal resistance (16°C/W) through alternative pad design. Both are electrically and mechanically compatible.

Q: Will the improved luminous flux (32lm vs. 30lm) affect circuit operation?

A: No. The substitute operates at identical forward voltage and test current. The improved flux is a performance enhancement that does not alter electrical characteristics or require circuit adjustment.

Q: Is the reduced height (0.80mm vs. 0.90mm) a concern for PCB assembly?

A: No. The lower profile is compatible with standard surface mount assembly processes and presents no clearance or soldering issues. This represents a design improvement.

Q: What is the availability status of the substitute part?

A: SPMWHT541MP5WAV0S4 is active production status with 85,670 units in stock, ensuring reliable long-term supply compared to the obsolete main part.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS Compliant, REACH Unaffected, ECCN (EAR99), and HTSUS (8541.41.0000) classifications.

Q: Can the substitute handle higher current applications?

A: The substitute has a maximum current rating of 180mA compared to 150mA for the main part. However, both parts are specified for 65mA test current operation. Higher current operation requires thermal analysis and is outside standard application scope.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts are MSL 2A (4 Weeks), indicating standard moisture sensitivity. Standard ESD and moisture control procedures apply during storage and assembly.
