Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WAWUS4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Color and CCT: White, Warm 2700K
• Flux @ 25°C at 65mA test current: 31lm (30lm ~ 32lm range)
• Forward Voltage (Vf) Typical: 2.95V
• Test Current: 65mA
• Maximum Current: 180mA
• Lumens/Watt @ Test Current: 162 lm/W
• Color Rendering Index (CRI): 80
• Viewing Angle: 120°

Mechanical Equivalence Requirements:

• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Mounting Type: Surface Mount
• Height - Seated (Max): 0.031" (0.80mm)
• Thermal Resistance: 15°C/W (or lower)
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

Compliance Requirements:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• ECCN: EAR99
• HTSUS: 8541.41.0000

All substitute parts listed maintain these specifications. Dimensional variations in length (0.197" vs. 0.220") do not affect substitution eligibility when all other parameters remain equivalent, as the 5630 package classification accommodates this tolerance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Highest Availability): SPMWHT541MP5WAW0S4 is the recommended primary substitute. This part maintains complete electrical and mechanical equivalence to the main part number, carries Active product status, and demonstrates the highest inventory availability (45,709 units). It holds ROHS3 Compliant certification, which exceeds the RoHS Compliant requirement of the original part.

Secondary Substitutes (Active Status, Adequate Availability):

• SPMWHT541MP5WAWMS4: Active status with substantial inventory (25,996 units). Dimensional length variation (0.220" vs. 0.197") remains within 5630 package tolerance. Suitable for applications where component length does not impose PCB layout constraints.
• SPMWHT541MP5WAWKS4: Active status with 871 units available. Maintains identical dimensions and thermal characteristics to the main part.
• SPMWHT541MP5WAWNS4: Active status with 726 units available. Maintains identical dimensions and thermal characteristics to the main part.

Tertiary Substitutes (Active Status, Limited Availability):

• SPMWHT541MP5WAWSS4: Active status with 1,008 units available. Thermal resistance of 14°C/W provides improved thermal performance compared to the main part's 15°C/W. ROHS3 Compliant certification. Suitable for applications requiring enhanced thermal management.
• SPMWHT541MP5WAWGS4: Active status with 860 units available. Thermal resistance of 14°C/W provides improved thermal performance. RoHS compliance status not explicitly specified in provided data.

Selection Criteria by Application Context:

• For immediate high-volume requirements: SPMWHT541MP5WAW0S4
• For applications with PCB length constraints: SPMWHT541MP5WAWUS4 (if available), SPMWHT541MP5WAW0S4, SPMWHT541MP5WAWKS4, SPMWHT541MP5WAWNS4, or SPMWHT541MP5WAWSS4
• For applications requiring enhanced thermal performance: SPMWHT541MP5WAWSS4 or SPMWHT541MP5WAWGS4
• For long-term supply chain stability: SPMWHT541MP5WAWMS4 or SPMWHT541MP5WAW0S4

All listed substitutes are manufactured by Samsung Semiconductor, Inc., ensuring consistent quality and reliability standards.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP5WAWMS4 be used as a direct replacement for SPMWHT541MP5WAWUS4?

A: Yes. SPMWHT541MP5WAWMS4 is electrically and mechanically equivalent. The dimensional length difference (0.220" vs. 0.197") falls within the 5630 package specification tolerance. Verify that your PCB layout accommodates the slightly longer component length before implementation.

Q2: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents a more recent certification standard. Parts with ROHS3 Compliant status (such as SPMWHT541MP5WAW0S4 and SPMWHT541MP5WAWSS4) meet current regulatory requirements and are suitable for new applications.

Q3: Does the thermal resistance difference between 15°C/W and 14°C/W affect substitution eligibility?

A: No. A lower thermal resistance value (14°C/W) represents improved thermal performance and does not compromise compatibility. Parts with 14°C/W thermal resistance (SPMWHT541MP5WAWSS4 and SPMWHT541MP5WAWGS4) are fully substitutable and provide enhanced thermal management characteristics.

Q4: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel packaging, maintaining consistency with the original part's packaging format for automated assembly processes.

Q5: What does "Not For New Designs" status mean for the main part number?

A: This designation indicates that Samsung has discontinued the SPMWHT541MP5WAWUS4 for new product development. Existing designs using this part number should transition to one of the Active substitute parts listed. All substitute parts carry Active product status, ensuring long-term availability and support.

Q6: Can I mix different substitute part numbers in the same production batch?

A: Yes. All substitute parts maintain identical electrical specifications (color, CCT, flux, voltage, current, CRI, viewing angle) and mechanical compatibility (package, dimensions, height, mounting type). Mixing substitute parts within a single production batch does not affect functional performance or reliability.

Q7: What is the Moisture Sensitivity Level (MSL) 2A (4 Weeks) requirement?

A: MSL 2A indicates the component can be stored in dry conditions for up to 4 weeks after packaging before soldering. After this period, the component must be baked according to IPC standards before use. All listed parts with specified MSL carry the same 2A (4 Weeks) rating.

Q8: Which substitute part offers the best long-term supply availability?

A: SPMWHT541MP5WAW0S4 demonstrates the highest inventory level (45,709 units) and Active product status, making it the most suitable choice for applications requiring long-term supply chain stability and high-volume procurement.
