Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP7WAWUS0 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color: White, Warm (fixed requirement)
• CCT: 2700K (fixed requirement)
• CRI: 90 (fixed requirement)
• Package / Case: 4-SMD, Flat Leads (mechanical compatibility)
• Supplier Device Package: 5630 (form factor)
• Size / Dimension: 5.00mm x 3.00mm (PCB footprint compatibility)
• Height - Seated (Max): 0.80mm (clearance compatibility)
• Viewing Angle: 120° (optical performance)
• Mounting Type: Surface Mount (assembly process compatibility)

Electrical Compatibility Parameters:

• Voltage - Forward (Vf): 2.95V ± tolerance (circuit design parameter)
• Current - Test: 65mA (nominal operating point)
• Current - Maximum: 180mA (absolute maximum rating)

Compliance Parameters:

• RoHS Status: RoHS Compliant or ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 2A (4 Weeks) (handling and storage)

Substitute parts are grouped into two categories:

Category 1: Direct Series Equivalent SPMWHT541MP7WAWMS0 maintains identical electrical specifications and package configuration as the main part, with improved thermal resistance (15°C/W vs. 20°C/W) and active product status.

Category 2: Parametric Equivalent (LM281B+ Series) SPMWH1228FD7W2W0SJ, SPMWH1228FD7W2WKSJ, SPMWH1228FD7W2WMSJ, SPMWH1228FD7WAW0SJ, SPMWH1228FD7WAWKSJ, and SPMWH1228FD7WAWMSJ represent functional equivalents from the LM281B+ series. These parts maintain identical color temperature (2700K), CRI (90), package configuration (5630, 4-SMD), and mechanical dimensions. Electrical differences include higher test current (150mA vs. 65mA) and forward voltage variations (2.9V or 3V vs. 2.95V), with maximum current rated at 200mA. All LM281B+ variants feature improved thermal resistance (25°C/W) and active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Minimal Circuit Modification):

SPMWHT541MP7WAWMS0 is the primary substitute for SPMWHT541MP7WAWUS0. Both parts maintain identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current) and mechanical configuration (5630 package, 4-SMD flat leads, 5.00mm x 3.00mm footprint). The SPMWHT541MP7WAWMS0 offers improved thermal resistance (15°C/W vs. 20°C/W) and active product status with ROHS3 compliance, providing superior long-term availability and regulatory alignment. This part requires no circuit redesign and maintains identical performance characteristics.

For Circuit-Level Substitution (LM281B+ Series):

The LM281B+ series parts (SPMWH1228FD7W2W0SJ, SPMWH1228FD7W2WKSJ, SPMWH1228FD7W2WMSJ, SPMWH1228FD7WAW0SJ, SPMWH1228FD7WAWKSJ, SPMWH1228FD7WAWMSJ) provide functional equivalence with the following considerations:

All LM281B+ variants maintain identical color temperature (2700K), CRI (90), package configuration (5630, 4-SMD), and mechanical dimensions. These parts feature higher test current (150mA vs. 65mA) and forward voltage options (2.9V or 3V vs. 2.95V). The forward voltage difference of ±0.05V to ±0.05V requires circuit verification to confirm compatibility with existing current-limiting resistor networks or driver circuits. All LM281B+ parts carry active product status and ROHS3 compliance with improved thermal resistance (25°C/W).

Compliance Considerations:

All substitute parts maintain RoHS compliance (ROHS3 standard for active parts). The transition from RoHS Compliant to ROHS3 Compliant represents regulatory advancement with no functional impact on component performance. All parts are manufactured by Samsung Semiconductor, Inc., ensuring consistent quality and supply chain reliability.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP7WAWMS0 be used as a direct drop-in replacement for SPMWHT541MP7WAWUS0?

A: Yes. SPMWHT541MP7WAWMS0 is a direct equivalent with identical electrical specifications (2.95V forward voltage, 65mA test current) and mechanical configuration (5630 package, 4-SMD flat leads, 5.00mm x 3.00mm). No circuit modification is required. The improved thermal resistance (15°C/W vs. 20°C/W) provides enhanced thermal performance.

Q2: What are the key differences between LM561B Plus and LM281B+ series parts?

A: Both series maintain identical color temperature (2700K), CRI (90), package configuration (5630, 4-SMD), and mechanical dimensions (5.00mm x 3.00mm, 0.80mm height). The primary differences are: LM281B+ operates at higher test current (150mA vs. 65mA), offers forward voltage options of 2.9V or 3V (vs. 2.95V), and features improved thermal resistance (25°C/W vs. 20°C/W). Circuit verification is required when substituting LM281B+ parts due to current and voltage differences.

Q3: Are there forward voltage compatibility concerns when substituting LM281B+ parts?

A: Forward voltage differences exist between part variants. SPMWH1228FD7W2W0SJ, SPMWH1228FD7W2WKSJ, and SPMWH1228FD7W2WMSJ operate at 2.9V (−0.05V from original 2.95V). SPMWH1228FD7WAW0SJ, SPMWH1228FD7WAWKSJ, and SPMWH1228FD7WAWMSJ operate at 3V (+0.05V from original 2.95V). These variations require verification against circuit design parameters, particularly in current-limiting resistor calculations and driver circuit specifications.

Q4: Do all substitute parts maintain the same package footprint?

A: Yes. All substitute parts use the 5630 supplier device package with 4-SMD flat leads configuration, maintaining identical PCB footprint (5.00mm x 3.00mm) and maximum seated height (0.80mm). Direct PCB compatibility is confirmed for all listed substitutes.

Q5: What is the significance of the product status change from "Not For New Designs" to "Active"?

A: Product status "Not For New Designs" indicates end-of-life classification for the SPMWHT541MP7WAWUS0, with limited future availability and no manufacturer support for new applications. All substitute parts carry "Active" status, confirming ongoing production, long-term availability, and manufacturer support. This transition is essential for supply chain continuity and regulatory compliance in production environments.

Q6: Are there inventory considerations for substitute part selection?

A: Inventory levels vary across substitute parts. SPMWHT541MP7WAWMS0 maintains the highest inventory (19,423 pcs), providing supply security. LM281B+ variants range from 648 to 1,139 pcs. Inventory status should be verified at time of procurement to confirm availability for production requirements.

Q7: Do all substitute parts meet current RoHS regulations?

A: Yes. SPMWHT541MP7WAWMS0 carries ROHS3 Compliant status. All LM281B+ variants carry ROHS3 Compliant status with REACH Unaffected designation. These certifications confirm compliance with current European Union regulatory requirements for restricted substances.
