Parameter Comparison

Engineering Selection Recommendations

For Existing Designs Using SPMWHT541MD5WATMS1:

The SPMWHT541MP5WATMS4 substitute part is electrically and mechanically compatible for direct replacement. Both components share identical base product number (SPMWHT541), matching 5630 package footprint, identical thermal resistance rating, and equivalent MSL classification. Forward voltage differential (2.9V to 2.95V) falls within acceptable tolerance for LED circuit design.

For New Design Implementation:

The SPMWHT541MP5WATMS4 is the recommended selection due to Active product status, ensuring long-term availability and manufacturing support. The substitute part provides enhanced specifications including higher maximum current rating (180mA vs 150mA), improved height profile (0.80mm vs 0.90mm), and documented performance metrics (172 lm/W, CRI 80, 120° viewing angle). ROHS3 compliance exceeds the RoHS Compliant status of the original part.

Compliance Considerations:

Both parts maintain identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring equivalent regulatory treatment. MSL rating of 2A (4 Weeks) is identical, requiring identical moisture control procedures during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WATMS4 be used as a direct drop-in replacement for SPMWHT541MD5WATMS1?

A: Yes. Both parts share identical 5630 package footprint (5.00mm x 3.00mm), surface mount configuration, thermal resistance (16°C/W), and forward voltage within acceptable tolerance (2.9V vs 2.95V). The substitute part has lower seated height (0.80mm vs 0.90mm), which is compatible with existing PCB layouts.

Q: What is the significance of the product status change from "Not For New Designs" to "Active"?

A: Active status indicates the SPMWHT541MP5WATMS4 is in current production with guaranteed long-term availability. The original part's "Not For New Designs" status signals end-of-life trajectory. For new product development, the substitute part ensures supply chain continuity and manufacturing support.

Q: Are there electrical parameter differences that affect circuit design?

A: Forward voltage increases from 2.9V to 2.95V (0.05V difference). Maximum current rating increases from 150mA to 180mA. Test current remains 65mA for both parts. These differences are within standard LED circuit design tolerances and do not require circuit modification.

Q: Do both parts require identical moisture handling procedures?

A: Yes. Both parts carry MSL rating of 2A (4 Weeks), requiring identical moisture sensitivity precautions during storage, handling, and assembly processes.

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

A: Both descriptions refer to 4-SMD surface mount configurations with identical footprint and thermal characteristics. The terminology variation reflects different documentation conventions from Samsung Semiconductor for the same physical package format.

Q: Is the substitute part compatible with existing pick-and-place equipment settings?

A: Yes. Identical 5.00mm x 3.00mm footprint and surface mount configuration ensure compatibility with existing assembly equipment. The lower seated height (0.80mm vs 0.90mm) of the substitute part is within standard PCB assembly tolerances.

Q: What compliance certifications apply to both parts?

A: Both parts carry RoHS compliance (substitute upgraded to ROHS3), identical ECCN classification (EAR99), and identical HTSUS code (8541.41.0000). Regulatory treatment is equivalent for export and domestic applications.
