Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WAW0SD is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color and correlated color temperature (CCT): White, Warm 2700K
• Forward voltage: 2.95V (typical)
• Test current: 65mA
• Color Rendering Index (CRI): 80
• Viewing angle: 120°
• Package type: 4-SMD configuration
• Supplier package designation: 5630
• Physical dimensions: 5.00mm × 3.00mm footprint

Secondary Compatibility Parameters:

• Surface mount mounting type
• RoHS compliance status
• Moisture sensitivity level (MSL 2A)

The substitute part SPMWHT541MP5WAWMS5 maintains all primary substitution criteria while operating within the same electrical envelope. Both parts share the LM561B base product number and are manufactured by Samsung Semiconductor, Inc.

Engineering Selection Recommendations

For Existing Designs (Maintenance & Repair): The SPMWHT541MD5WAW0SD remains suitable for replacement applications where existing inventory is depleted. The part maintains active RoHS compliance and meets all specified electrical and thermal parameters.

For Ongoing Production: The SPMWHT541MP5WAWMS5 is the recommended substitute for new production runs and long-term sourcing. This part carries "Active" product status, ensuring continued availability and supply chain stability. The substitute delivers improved efficiency (172 lm/W versus 167 lm/W) and enhanced thermal performance (15°C/W versus 16°C/W) while maintaining electrical compatibility at the 65mA test current.

Compliance Considerations: Both parts satisfy RoHS requirements. The substitute achieves ROHS3 compliance, representing the current regulatory standard. Both components maintain identical MSL ratings and are suitable for standard surface mount assembly processes.

Thermal and Mechanical Compatibility: The substitute part exhibits a 0.10mm reduction in seated height (0.80mm versus 0.90mm), which is within typical PCB assembly tolerances for 5630 package footprints. The improved thermal resistance of the substitute part provides enhanced heat dissipation characteristics.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAWMS5 be used as a direct replacement for SPMWHT541MD5WAW0SD?

A: Yes. Both parts operate at identical forward voltage (2.95V), test current (65mA), color temperature (2700K), and CRI (80). The 5630 package footprint and 4-SMD configuration are mechanically compatible. The substitute part is electrically and mechanically interchangeable in existing circuit designs.

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

A: Both designations refer to 4-SMD surface mount configurations with 5.00mm × 3.00mm footprints. The primary difference is the exposed pad thermal interface on the main part versus standard flat leads on the substitute. Both configurations are compatible with standard reflow soldering processes and PCB layouts designed for the 5630 package.

Q: Why is the main part marked "Not For New Designs"?

A: This designation indicates that Samsung Semiconductor has transitioned this product to end-of-life status. The SPMWHT541MP5WAWMS5 (LM561B Plus variant) represents the active product line continuation. For new product development, the substitute part is the appropriate selection.

Q: Are there any performance differences between these parts at the 65mA test current?

A: At 65mA test current, both parts deliver equivalent forward voltage (2.95V) and viewing angle (120°). The substitute part produces slightly higher luminous flux (33lm versus 32lm) and improved efficiency (172 lm/W versus 167 lm/W). These differences fall within normal manufacturing tolerances and do not affect circuit operation.

Q: What is the maximum current rating for each part?

A: The main part (SPMWHT541MD5WAW0SD) is rated for maximum 150mA. The substitute part (SPMWHT541MP5WAWMS5) is rated for maximum 180mA. Both parts operate safely at the standard 65mA test current. The higher maximum rating on the substitute provides additional design margin for applications requiring increased current headroom.

Q: Are both parts RoHS compliant?

A: Yes. The main part carries RoHS Compliant status. The substitute part carries ROHS3 Compliant status, which represents the current regulatory standard. Both parts meet environmental compliance requirements for electronic component manufacturing and use.

Q: What is the moisture sensitivity level, and how does it affect handling?

A: Both parts carry MSL 2A rating with a 4-week floor life. This indicates the component can be exposed to ambient conditions (23°C ± 2°C, 45% ± 5% RH) for up to 4 weeks before requiring bake-out prior to reflow soldering. Standard moisture control procedures for surface mount assembly apply to both parts.
