Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP5WAVUS4 are determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Color temperature: 3000K (warm white)
• Forward voltage: 2.95V typical
• Test current: 65mA
• Maximum current: 180mA
• Luminous flux: 32lm at 25°C, 65mA (31lm ~ 33lm range)
• Lumens/Watt efficiency: 167 lm/W
• CRI: 80
• Viewing angle: 120°

Mechanical Equivalence Criteria:

• Package type: 4-SMD, Flat Leads
• Supplier device package: 5630
• Physical dimensions: 5.00mm L x 3.00mm W
• Maximum seated height: 0.80mm
• Mounting type: Surface Mount
• Packaging format: Tape & Reel (TR)

Compliance Equivalence Criteria:

• Moisture Sensitivity Level: 2A (4 Weeks)
• ECCN: EAR99
• HTSUS: 8541.41.0000

All five substitute parts (SPMWHT541MP5WAV0S4, SPMWHT541MP5WAVKS4, SPMWHT541MP5WAVMS4, SPMWHT541MP5WAVNS4, SPMWHT541MP5WAVSS4) maintain complete parametric equivalence across these criteria. Variations in thermal resistance (14°C/W to 16°C/W) and RoHS certification status (RoHS Compliant vs. ROHS3 Compliant) do not affect functional substitutability for the specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes for Active Production:

For new designs and ongoing production, SPMWHT541MP5WAVMS4 is the recommended primary substitute. This part maintains complete electrical and mechanical equivalence to SPMWHT541MP5WAVUS4 while offering the highest inventory availability (50,200 units) and active product status. SPMWHT541MP5WAVMS4 carries ROHS3 Compliant certification, providing enhanced regulatory compliance for applications requiring the latest RoHS standards.

Secondary Substitutes:

SPMWHT541MP5WAV0S4 serves as an alternative primary substitute with the largest available inventory (85,670 units) and active product status. This part is RoHS Compliant and maintains identical electrical specifications. The thermal resistance specification of 16°C/W is within acceptable variance for the LM561B Plus series.

SPMWHT541MP5WAVNS4 and SPMWHT541MP5WAVKS4 are suitable substitutes with active product status and RoHS Compliant certification. Both maintain the 15°C/W thermal resistance specification matching the original part.

Tertiary Substitute:

SPMWHT541MP5WAVSS4 is functionally equivalent with active product status and ROHS3 Compliant certification. This part offers the lowest thermal resistance (14°C/W) among all substitutes, which may provide thermal performance advantages in thermally constrained applications. Inventory availability is 877 units.

Compliance Considerations:

All substitute parts maintain identical MSL 2A (4 Weeks) moisture sensitivity specifications and ECCN/HTSUS classifications. Selection between RoHS Compliant and ROHS3 Compliant variants should be based on specific application regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 be used as a direct replacement for SPMWHT541MP5WAVUS4 in existing designs?

A: Yes. SPMWHT541MP5WAVMS4 is a parametric equivalent with identical electrical characteristics (2.95V forward voltage, 65mA test current, 32lm flux, 167 lm/W efficiency), mechanical specifications (5630 package, 5.00mm x 3.00mm dimensions, 0.80mm height), and compliance requirements (MSL 2A, RoHS status). Direct substitution is supported without circuit modification.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant variants?

A: ROHS3 Compliant parts (SPMWHT541MP5WAVMS4 and SPMWHT541MP5WAVSS4) meet the latest RoHS 3 directive requirements. RoHS Compliant parts meet the original RoHS directive. Both are functionally equivalent for the specified electrical and mechanical parameters. Selection depends on application regulatory requirements.

Q: Are there thermal resistance differences between substitute parts?

A: Thermal resistance varies between 14°C/W and 16°C/W across the substitute portfolio. SPMWHT541MP5WAVSS4 offers 14°C/W, SPMWHT541MP5WAVMS4 and SPMWHT541MP5WAV0S4 offer 16°C/W, while SPMWHT541MP5WAVKS4 and SPMWHT541MP5WAVNS4 offer 15°C/W. These variations do not affect functional substitutability for standard applications but may be relevant for thermally constrained designs.

Q: Which substitute part has the best inventory availability?

A: SPMWHT541MP5WAV0S4 has the highest inventory availability with 85,670 units in stock. SPMWHT541MP5WAVMS4 is the second option with 50,200 units available.

Q: Can I mix different substitute part numbers in the same production batch?

A: All substitute parts maintain identical electrical and mechanical specifications, allowing interchangeability within the same design. However, production traceability and quality documentation may require consistent part number usage within individual manufacturing lots.

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

A: All parts carry MSL 2A (4 Weeks) rating, indicating the component can be stored in a dry environment for up to 4 weeks before soldering. After this period, parts must be baked according to IPC-A-2.1 standards before assembly to prevent moisture-induced defects.

Q: Are the 5630 package dimensions identical across all substitute parts?

A: Yes. All substitute parts use the 5630 package format with identical dimensions: 5.00mm length x 3.00mm width x 0.80mm maximum seated height. PCB footprints and assembly processes are fully compatible.

Q: Why is the original SPMWHT541MP5WAVUS4 marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. Samsung recommends using active substitute parts for new designs and ongoing production to ensure long-term availability and manufacturer support.
