Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP7WAW0S0 are determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Color and correlated color temperature (CCT): White, Warm 2700K
• Luminous flux range @ 25°C, 65mA test current: 22lm to 28lm
• Forward voltage (Vf): 2.95V typical
• Test current: 65mA
• Maximum current rating: 180mA
• Lumens per watt efficiency: 130 lm/W
• Color Rendering Index (CRI): 90
• Viewing angle: 120°

Mechanical Equivalence Criteria:

• Package type: 4-SMD, Flat Leads
• Supplier device package: 5630
• Physical dimensions: 5.00mm L x 3.00mm W x 0.80mm H (Max)
• Mounting type: Surface Mount
• Thermal resistance: 15°C/W

Compliance Equivalence Criteria:

• RoHS compliance status
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)
• Base product number: SPMWHT541

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAWMS0 is a direct parametric equivalent to the SPMWHT541MP7WAW0S0. Both parts are manufactured by Samsung Semiconductor and share identical electrical, mechanical, and thermal specifications. The primary distinction is the RoHS compliance designation: the main part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status. Both designations confirm lead-free and hazardous substance compliance.

Selection between these two parts should be based on:

1. Supply Availability: The SPMWHT541MP7WAWMS0 has significantly higher inventory (19,423 units) compared to the main part (745 units), making it suitable for high-volume production requirements.

2. Compliance Requirements: If ROHS3 certification is explicitly required by your procurement or regulatory framework, the SPMWHT541MP7WAWMS0 is the appropriate choice. If RoHS Compliant status is sufficient, either part is acceptable.

3. Design Continuity: Both parts are active products from the same manufacturer and series, ensuring long-term availability and consistent performance in existing designs.

No electrical circuit modifications, thermal management adjustments, or PCB layout changes are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAWMS0 be used as a direct replacement for SPMWHT541MP7WAW0S0 in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics (2.95V forward voltage, 65mA test current, 25lm flux), mechanical dimensions (5630 package, 5.00mm x 3.00mm x 0.80mm), and thermal properties (15°C/W). No circuit redesign is required.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations confirm compliance with lead-free and hazardous substance restrictions. ROHS3 represents the current revision of the RoHS directive. Both are acceptable for most applications; verify your specific regulatory requirements.

Q: Are the 5630 package dimensions identical between both parts?

A: Yes. Both parts use the 4-SMD, Flat Leads 5630 package with dimensions of 5.00mm length, 3.00mm width, and 0.80mm maximum height. PCB footprints and reflow profiles are identical.

Q: What is the significance of the 120° viewing angle specification?

A: The 120° viewing angle indicates the half-angle at which luminous intensity drops to 50% of peak. This specification is identical for both parts and determines suitability for applications requiring wide-angle light distribution.

Q: Can these parts be operated at the 180mA maximum current rating?

A: Both parts are rated for maximum current of 180mA. However, operation at maximum current will increase junction temperature and reduce luminous efficiency. The 65mA test current represents the standard operating point where the 130 lm/W efficiency specification applies.

Q: What is the Moisture Sensitivity Level (MSL) 2A rating?

A: MSL 2A indicates the component can be stored in dry conditions for up to 4 weeks before soldering. Both parts carry this identical rating and require standard moisture control during assembly.

Q: Are there any thermal management differences between these parts?

A: No. Both parts have identical thermal resistance of 15°C/W. Thermal design calculations and heat dissipation strategies remain unchanged when substituting between these parts.
