Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WAWHSC is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Series family: LM561B or LM561B Plus
• Color specification: White, Warm
• Correlated color temperature: 2700K
• Forward voltage: 2.95V (nominal)
• Test current: 65mA
• Viewing angle: 120°
• Mounting type: Surface Mount
• Package family: 5630 (4-SMD configuration)
• Compliance: RoHS Compliant

Secondary Compatibility Parameters:

• CRI (Color Rendering Index): 80 or higher
• Thermal resistance: Within acceptable range for thermal management design
• MSL rating: 2A or better
• Supplier device package designation: 5630

The SPMWHT541MP5WAWMS4 qualifies as a direct substitute based on matching all primary criteria. This part belongs to the LM561B Plus product line, representing an enhanced variant within the same base product family (SPMWHT541). Both components share identical electrical operating parameters at the specified test conditions and are compatible with existing PCB layouts designed for 5630 package footprints.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPMWHT541MD5WAWHSC is designated "Not For New Designs," indicating Samsung has transitioned this component to mature production status with no planned enhancements or extended support. The SPMWHT541MP5WAWMS4 carries "Active" product status, confirming ongoing manufacturing support and availability for new design implementations.

Performance Characteristics: Both parts operate at identical nominal electrical parameters (2.95V, 65mA test current). The SPMWHT541MP5WAWMS4 demonstrates improved luminous efficiency at 162 lm/W compared to 156 lm/W for the original part, while maintaining the same 30–31 lumen output range at test conditions. This efficiency improvement reflects Samsung's LM561B Plus product line enhancement.

Mechanical and Thermal Compatibility: The SPMWHT541MP5WAWMS4 exhibits a 0.1mm length increase (5.60mm vs. 5.00mm) and 0.1mm height reduction (0.80mm vs. 0.90mm). These dimensional variations remain within typical PCB layout tolerances for 5630 package footprints. The substitute part provides superior thermal performance at 15°C/W versus 16°C/W, enabling more efficient heat dissipation in thermal-constrained applications.

Compliance and Supply Chain: Both components maintain RoHS compliance and identical MSL ratings (2A, 4 weeks). The SPMWHT541MP5WAWMS4 offers significantly higher inventory availability (25,996 pcs vs. 1,125 pcs), supporting production continuity and reducing supply chain risk.

Maximum Current Rating: The SPMWHT541MP5WAWMS4 supports a higher maximum current rating of 180mA compared to 150mA for the original part, providing additional operational headroom for applications requiring current flexibility within the same thermal envelope.

Frequently Asked Questions (FAQ)

Q: Can the SPMWHT541MP5WAWMS4 be used as a direct replacement for SPMWHT541MD5WAWHSC in existing designs?

A: Yes. Both parts share identical electrical operating parameters at the specified test current (65mA, 2.95V), color specification (2700K warm white), viewing angle (120°), and package family (5630 4-SMD). The dimensional differences (0.1mm length and height variations) fall within standard PCB layout tolerances for this package class. Existing footprints and circuit designs require no modification.

Q: What are the key differences between these two parts?

A: The SPMWHT541MP5WAWMS4 represents the LM561B Plus product line variant with three primary distinctions: (1) Active product status versus "Not For New Designs" status; (2) improved luminous efficiency of 162 lm/W versus 156 lm/W; (3) higher maximum current rating of 180mA versus 150mA; (4) superior thermal resistance of 15°C/W versus 16°C/W; (5) slightly larger length dimension (5.60mm vs. 5.00mm) and lower height (0.80mm vs. 0.90mm).

Q: Are there any package or lead configuration differences?

A: Both parts use the 5630 supplier device package with 4-SMD surface mount configuration. The SPMWHT541MD5WAWHSC features flat lead with exposed pad construction, while the SPMWHT541MP5WAWMS4 uses flat leads. This distinction does not affect PCB compatibility for standard 5630 footprints, as both configurations are mechanically and electrically compatible with the same land pattern design.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates Samsung has completed the active development phase for the SPMWHT541MD5WAWHSC and is transitioning the component to end-of-life management. While the part remains available in current inventory, Samsung provides no commitment for future production, design support, or performance improvements. New designs should incorporate the SPMWHT541MP5WAWMS4 to ensure long-term supply chain stability and access to active product support.

Q: Are the luminous flux specifications compatible?

A: Yes. The SPMWHT541MD5WAWHSC delivers 30 lumens (28–32 lm range) at test conditions, while the SPMWHT541MP5WAWMS4 delivers 31 lumens (30–32 lm range). Both specifications overlap within the 30–32 lumen band, ensuring equivalent light output performance for applications designed around this flux range.

Q: How do the thermal characteristics compare?

A: The SPMWHT541MP5WAWMS4 provides superior thermal performance with a thermal resistance of 15°C/W compared to 16°C/W for the original part. This 1°C/W improvement, combined with the lower seated height (0.80mm vs. 0.90mm), enables more efficient heat transfer to the PCB substrate. For thermally constrained applications, the substitute part offers measurable thermal management advantages.

Q: Is inventory availability a consideration for component selection?

A: Current inventory levels show 1,125 pcs for SPMWHT541MD5WAWHSC versus 25,996 pcs for SPMWHT541MP5WAWMS4. The substitute part provides substantially higher stock availability, reducing procurement lead times and supply chain risk for production volumes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SPMWHT541MD5WAWHSC and SPMWHT541MP5WAWMS4 are RoHS Compliant with identical MSL ratings (2A, 4 weeks storage at controlled humidity). ECCN and HTSUS classifications are identical, ensuring equivalent regulatory and export compliance status.
