Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD7WAWHS0 is determined by strict alignment across the following critical parameters:

Electrical Compatibility Requirements:

• Color and CCT must remain White, Warm 2700K
• Forward voltage must be 2.95V (typical)
• Test current must be 65mA
• CRI must be 90 or higher
• Viewing angle must be 120°

Mechanical Compatibility Requirements:

• Package type must be 4-SMD configuration
• Supplier package designation must be 5630
• Physical dimensions must be 5.00mm × 3.00mm
• Height must not exceed 0.90mm seated

Thermal & Environmental Requirements:

• Thermal resistance must be within acceptable range for the application
• MSL rating must be 2A or better
• RoHS compliance required

The SPMWHT541MP7WAWMS0 qualifies as a direct substitute based on these parameters. Both parts share the same base product number (SPMWHT541), identical color temperature, forward voltage, test current, CRI, viewing angle, and mechanical dimensions. The substitute part demonstrates improved performance characteristics while maintaining full compatibility with existing designs.

Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP7WAWMS0

The SPMWHT541MP7WAWMS0 is the qualified equivalent for the SPMWHT541MD7WAWHS0. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The main part carries "Not For New Designs" status, while the substitute maintains "Active" product status. This transition ensures continued availability and manufacturing support for ongoing production requirements.

Compliance Enhancement: The substitute part meets ROHS3 compliance, representing an upgrade from the main part's RoHS compliance. This provides enhanced environmental and regulatory alignment for current manufacturing standards.

Performance Characteristics: The substitute delivers measurable improvements across key performance metrics while maintaining identical electrical operating parameters. Luminous flux increases from 23lm to 25lm, efficiency improves from 120 lm/W to 130 lm/W, and maximum current rating increases from 150mA to 180mA. Thermal resistance improves from 16°C/W to 15°C/W, and seated height reduces from 0.90mm to 0.80mm.

Mechanical Compatibility: Both parts share identical base product number, color temperature, forward voltage, test current, CRI, viewing angle, and physical footprint dimensions. The 5630 package designation and 4-SMD configuration ensure direct compatibility with existing PCB layouts and assembly processes.

Thermal Management: The improved thermal resistance of the substitute part (15°C/W versus 16°C/W) provides enhanced heat dissipation characteristics, supporting more demanding thermal environments without design modification.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAWMS0 be used as a direct replacement for SPMWHT541MD7WAWHS0 in existing designs?

A: Yes. Both parts share identical forward voltage (2.95V), test current (65mA), color temperature (2700K), CRI (90), viewing angle (120°), and physical dimensions (5.00 × 3.00mm). The substitute part is mechanically and electrically compatible with existing PCB layouts and circuit designs without modification.

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

A: The substitute part (SPMWHT541MP7WAWMS0) offers enhanced performance: luminous flux increases from 23lm to 25lm, efficiency improves from 120 lm/W to 130 lm/W, maximum current rating increases from 150mA to 180mA, thermal resistance improves from 16°C/W to 15°C/W, and seated height reduces from 0.90mm to 0.80mm. The substitute also carries ROHS3 compliance versus RoHS compliance for the main part.

Q: Are there any package differences that affect assembly compatibility?

A: Both parts use the 5630 supplier package designation and 4-SMD configuration. The main part specifies "Flat Lead Exposed Pad" while the substitute specifies "Flat Leads." Both configurations are compatible with standard surface mount assembly processes. The substitute's reduced height (0.80mm versus 0.90mm) provides additional clearance margin in space-constrained applications.

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

A: This designation indicates the part is in mature or end-of-life phase. The SPMWHT541MP7WAWMS0 substitute maintains active product status, ensuring continued manufacturing support, availability, and compliance with current industry standards for new design implementations.

Q: Are the thermal characteristics suitable for high-current applications?

A: The substitute part supports higher maximum current (180mA versus 150mA) and provides improved thermal resistance (15°C/W versus 16°C/W). These characteristics make the substitute part suitable for applications requiring higher current operation or enhanced thermal performance.

Q: What is the significance of the ROHS3 compliance upgrade?

A: ROHS3 compliance represents alignment with current environmental and regulatory requirements. This upgrade ensures the substitute part meets the latest standards for hazardous substance restrictions, supporting compliance with current procurement and manufacturing regulations.

Q: Are inventory levels a consideration for part selection?

A: The substitute part (SPMWHT541MP7WAWMS0) maintains significantly higher inventory availability (19,423 pieces) compared to the main part (1,020 pieces). This availability advantage supports production continuity and reduces supply chain risk for ongoing manufacturing requirements.
