Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WAPMS4 is determined by strict parametric matching across electrical, optical, and mechanical specifications. The following criteria establish valid substitute relationships:

Electrical Parameters: Forward voltage (2.95V typical), test current (65mA), and maximum current rating (180mA) must remain constant. Flux output at 25°C and 65mA test current must fall within the specified range of 32–34 lumens.

Optical Parameters: Color temperature (6500K cool white), Color Rendering Index (80), and viewing angle (120°) must be identical.

Mechanical Parameters: Package configuration (4-SMD, flat leads), supplier device package designation (5630), physical dimensions (5.00mm × 3.00mm), and seated height (0.80mm maximum) must match exactly.

Compliance & Environmental: RoHS compliance status, Moisture Sensitivity Level (2A, 4 Weeks), and product status (Active) must be maintained or improved.

Series Designation: All substitutes must belong to the LM561B Plus series.

The SPMWHT541MP5WAPKS4 qualifies as a parametric equivalent based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP5WAPKS4 is a direct parametric equivalent to the SPMWHT541MP5WAPMS4. Both components are manufactured by Samsung Semiconductor and maintain identical electrical, optical, and mechanical specifications across all critical parameters. The substitute part demonstrates improved RoHS3 compliance status compared to the main part's RoHS Compliant designation, representing an advancement in regulatory alignment.

Efficiency performance shows a minor variance in lumens per watt (167 lm/W versus 172 lm/W), which falls within normal manufacturing tolerance ranges for LED components and does not affect functional equivalence. Both parts operate at identical forward voltage, test current, and maximum current ratings, ensuring direct circuit compatibility without design modification.

Both components maintain Active product status and identical Moisture Sensitivity Level ratings (2A, 4 Weeks), confirming equivalent handling and storage requirements. The SPMWHT541MP5WAPKS4 demonstrates significantly higher inventory availability (48,482 pieces versus 919 pieces), making it suitable for high-volume production requirements and supply chain continuity planning.

Selection between these equivalent parts should be based on inventory availability, supply chain logistics, and compliance documentation requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAPKS4 be used as a direct replacement for SPMWHT541MP5WAPMS4 in existing designs?

A: Yes. Both components are parametric equivalents with identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), optical characteristics (6500K, 80 CRI, 120° viewing angle), and mechanical dimensions (5.00mm × 3.00mm, 0.80mm height). No circuit design modifications are required.

Q: What is the significance of the lumens per watt difference (172 lm/W vs. 167 lm/W)?

A: The 5 lm/W variance represents approximately 2.9% efficiency difference and falls within standard manufacturing tolerance ranges for LED components. Both parts deliver the specified 33 lumens at 25°C and 65mA test current, confirming functional equivalence for lighting applications.

Q: Are there any differences in handling or storage requirements between these parts?

A: No. Both components carry identical Moisture Sensitivity Level ratings (2A, 4 Weeks), requiring the same storage conditions, handling procedures, and desiccant packaging protocols.

Q: What does the RoHS3 compliance designation on SPMWHT541MP5WAPKS4 indicate?

A: RoHS3 Compliant represents an updated regulatory compliance standard compared to RoHS Compliant. This indicates the substitute part meets current European Union Restriction of Hazardous Substances directives and may be preferred for applications requiring the latest compliance documentation.

Q: Are both parts suitable for high-volume production?

A: Yes. However, SPMWHT541MP5WAPKS4 offers significantly higher inventory availability (48,482 pieces) compared to SPMWHT541MP5WAPMS4 (919 pieces), making it more suitable for large-scale manufacturing runs and reducing supply chain risk.

Q: Do these parts require different PCB footprints or reflow profiles?

A: No. Both components use identical 4-SMD flat lead packaging in the 5630 supplier device package format with matching physical dimensions. PCB footprints, reflow temperature profiles, and assembly processes remain unchanged.

Q: What is the thermal resistance specification, and how does it affect circuit design?

A: Both parts specify 15°C/W thermal resistance. This parameter determines heat dissipation characteristics and should be factored into thermal management calculations for high-current or high-ambient-temperature applications.

Q: Can these parts be mixed within the same production batch?

A: Yes. Since both components are parametric equivalents with identical specifications, they can be used interchangeably within the same design and production batch without affecting performance or reliability.
