Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541ML5XAVGS0 is determined by the following critical parameters:

• Color Temperature (CCT): 3000K warm white specification
• Package Format: 4-SMD, Flat Leads in 5630 footprint
• Viewing Angle: 120° beam angle
• Mounting Type: Surface Mount
• Physical Dimensions: 5.00mm × 3.00mm × 0.80mm maximum height
• Color Rendering Index (CRI): 80 minimum
• Electrical Compatibility: Forward voltage and current ratings within acceptable operating ranges for the same application class

The substitute part SPMWHT541MP5WAVMS4 shares identical package geometry, color temperature, viewing angle, and mounting characteristics. Both components are manufactured by Samsung Semiconductor and maintain the same 5630 footprint, enabling direct mechanical and thermal compatibility. The substitute part operates at Active product status, providing ongoing supply assurance.

Parameter Comparison

Engineering Selection Recommendations

For End-of-Life Replacement: The SPMWHT541MP5WAVMS4 is the designated substitute for SPMWHT541ML5XAVGS0 applications. The substitute part carries Active product status, ensuring continued availability and supply chain stability. Both components share identical mechanical footprints and thermal mounting characteristics, permitting direct board-level substitution without PCB redesign.

Compliance Considerations: The substitute part meets ROHS3 compliance, representing an advancement over the RoHS Compliant status of the main part. Both components carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining regulatory consistency for export and procurement purposes.

Electrical Parameter Differences: The substitute part operates at 2.95V forward voltage compared to 2.75V for the main part, representing a 0.20V increase. This difference requires circuit-level verification to confirm compatibility with existing current-limiting resistor networks and power supply designs. The substitute part exhibits lower luminous flux (32lm versus 35lm) and reduced efficiency (167 lm/W versus 196 lm/W) at the 65mA test current. Maximum current rating is 180mA for the substitute versus 200mA for the main part.

Thermal Management: The substitute part exhibits higher thermal resistance (16°C/W versus 12°C/W), requiring thermal design review in applications with constrained thermal budgets or high ambient temperature operation.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 be used as a direct replacement for SPMWHT541ML5XAVGS0 without circuit modification?

A: Mechanical and thermal compatibility is direct due to identical 5630 package geometry and mounting characteristics. Electrical compatibility requires circuit verification. The 0.20V forward voltage increase and reduced maximum current rating (180mA versus 200mA) must be evaluated against existing current-limiting designs and power supply specifications.

Q: What are the key differences between these two LED components?

A: The main differences are: (1) Product Status—the substitute is Active while the main part is Not For New Designs; (2) Forward Voltage—2.95V versus 2.75V; (3) Luminous Flux—32lm versus 35lm at 65mA test current; (4) Efficiency—167 lm/W versus 196 lm/W; (5) Thermal Resistance—16°C/W versus 12°C/W; (6) Maximum Current—180mA versus 200mA; (7) RoHS Status—ROHS3 Compliant versus RoHS Compliant. Color temperature, CRI, viewing angle, and package format remain identical.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components are 5.00mm length × 3.00mm width × 0.80mm maximum seated height in 4-SMD, Flat Leads configuration. PCB footprints are identical.

Q: What is the impact of the higher thermal resistance in the substitute part?

A: The substitute part exhibits 4°C/W higher thermal resistance (16°C/W versus 12°C/W). In applications with high ambient temperatures or limited thermal dissipation, this results in higher junction temperatures at equivalent power levels. Thermal design analysis is required for applications operating above 50°C ambient or with constrained thermal paths.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both components carry MSL 2A (4 Weeks) classification, requiring identical moisture control procedures during storage, handling, and reflow soldering operations.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The substitute part meets ROHS3 Compliant status versus RoHS Compliant for the main part, representing regulatory advancement. No export or procurement restrictions differ between the two components.

Q: What is the luminous flux difference at the test current?

A: At 65mA test current and 25°C, the main part produces 35lm while the substitute produces 32lm, representing a 3lm (8.6%) reduction. This difference must be evaluated against application brightness requirements and photometric specifications.
