Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Series):

SPMWHT541MP5WAVMS5 is the primary substitute for SPMWHT541MP5WAVMS0. Both parts belong to the LM561B Plus series and share identical electrical and mechanical specifications. The key advantage of SPMWHT541MP5WAVMS5 is its Active product status and significantly higher inventory availability (26,898 units versus 782 units). This part carries ROHS3 compliance, which exceeds the RoHS compliance of the original part. Forward voltage, test current, maximum current, viewing angle, package configuration, and thermal characteristics are identical. Flux output is marginally higher at 34lm (33-35lm range) compared to 33lm (31-35lm range), representing improved luminous efficiency at 177 lm/W versus 172 lm/W. This part is suitable for direct substitution in existing designs without circuit modification.

Parametric Equivalents (LM561C Series):

SPMWHT541ML5XAVMS0, SPMWHT541ML5XAV0S0, and SPMWHT541ML5XAVKS0 are parametric equivalents from the LM561C series. All three parts maintain the same color temperature (3000K), CRI (80), viewing angle (120°), package type (4-SMD, Flat Leads 5630), physical dimensions (5.00mm x 3.00mm x 0.80mm), test current (65mA), and maximum current (180mA). All carry RoHS compliance and 2A MSL rating.

The primary electrical difference is forward voltage: LM561C variants operate at 2.75V to 2.8V compared to 2.95V for the LM561B Plus. This 0.15V to 0.20V reduction in forward voltage results in improved luminous efficiency (181-185 lm/W versus 172 lm/W). Thermal resistance is improved to 12°C/W compared to 15°C/W. All LM561C variants carry Active product status, ensuring long-term availability.

SPMWHT541ML5XAVMS0 offers the highest inventory availability (73,676 units) among all substitutes and represents the optimal choice for new procurement when forward voltage tolerance permits. SPMWHT541ML5XAV0S0 and SPMWHT541ML5XAVKS0 provide equivalent performance with lower inventory levels (969 and 881 units respectively).

Selection Criteria:

• For existing designs with strict forward voltage specification: Select SPMWHT541MP5WAVMS5 (LM561B Plus, 2.95V)
• For new designs or designs with forward voltage tolerance: Select SPMWHT541ML5XAVMS0 (LM561C, 2.8V, highest availability)
• For applications requiring maximum thermal performance: Any LM561C variant (12°C/W thermal resistance)
• For applications requiring maximum luminous efficiency: Any LM561C variant (181-185 lm/W)

All substitute parts are electrically and mechanically compatible with the original SPMWHT541MP5WAVMS0 within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS5 be used as a direct replacement for SPMWHT541MP5WAVMS0?

A: Yes. SPMWHT541MP5WAVMS5 is a direct replacement. Both parts are LM561B Plus series with identical forward voltage (2.95V), test current (65mA), maximum current (180mA), package configuration (4-SMD, Flat Leads 5630), viewing angle (120°), and thermal resistance (15°C/W). The only differences are improved product status (Active versus Not For New Designs), higher inventory availability, and ROHS3 compliance. No circuit modification is required.

Q: What is the difference between LM561B Plus and LM561C series?

A: The primary difference is forward voltage. LM561B Plus operates at 2.95V typical, while LM561C operates at 2.75V to 2.8V typical. This voltage reduction in LM561C results in improved luminous efficiency (181-185 lm/W versus 172 lm/W) and better thermal performance (12°C/W versus 15°C/W). All other parameters—color temperature (3000K), CRI (80), viewing angle (120°), package type (5630), and electrical ratings (65mA test, 180mA max)—are identical. LM561C variants carry Active product status, ensuring continued availability.

Q: Can LM561C parts substitute for LM561B Plus in existing designs?

A: LM561C parts are parametric equivalents suitable for substitution if the design tolerates the lower forward voltage (2.75V to 2.8V versus 2.95V). The reduced voltage results in lower power consumption and improved efficiency. If the circuit design includes current-limiting resistors or constant-current drivers, the voltage difference is typically accommodated without modification. If the design uses a fixed voltage supply with tight tolerance requirements, forward voltage compatibility must be verified before substitution.

Q: Why do the LM561C variants have different forward voltages (2.75V, 2.8V)?

A: The three LM561C variants (SPMWHT541ML5XAV0S0 at 2.75V, SPMWHT541ML5XAVMS0 at 2.8V, and SPMWHT541ML5XAVKS0 at 2.75V) represent different manufacturing lots or binning categories within the LM561C series. All three maintain the same flux output (33lm at 65mA), CRI (80), and package specifications. The forward voltage variation (2.75V to 2.8V) falls within acceptable operating range and does not affect functional compatibility. Selection among these three variants can be based on inventory availability and forward voltage preference.

Q: What is the significance of the product status "Not For New Designs"?

A: "Not For New Designs" indicates that SPMWHT541MP5WAVMS0 has reached end-of-life status and Samsung Semiconductor is no longer actively manufacturing this part. Existing inventory (782 units) is available for current applications, but long-term supply is not guaranteed. For new designs or applications requiring extended component availability, substitution to an Active status part (SPMWHT541MP5WAVMS5 or any LM561C variant) is recommended.

Q: Are all substitute parts RoHS compliant?

A: Yes. SPMWHT541MP5WAVMS0 carries RoHS compliance. SPMWHT541MP5WAVMS5 carries ROHS3 compliance (enhanced standard). All LM561C variants (SPMWHT541ML5XAVMS0, SPMWHT541ML5XAV0S0, SPMWHT541ML5XAVKS0) carry RoHS compliance. All parts meet environmental and regulatory requirements for electronic component use.

Q: What is the MSL rating and why is it important?

A: MSL (Moisture Sensitivity Level) 2A (4 Weeks) indicates that these components can be exposed to ambient conditions (30°C, 60% relative humidity) for up to 4 weeks before soldering without requiring baking. All substitute parts carry the same 2A (4 Weeks) rating as the original part. This specification is critical for supply chain management and assembly planning. Components must be stored in dry conditions and baked according to IPC standards if the 4-week exposure limit is exceeded.

Q: Can these LED parts be used interchangeably in the same PCB assembly?

A: Yes, all substitute parts share identical package configuration (4-SMD, Flat Leads 5630), physical dimensions (5.00mm x 3.00mm x 0.80mm), and mounting type (Surface Mount). PCB footprints and assembly processes require no modification. However, if the circuit design includes forward voltage-dependent components (such as precision current sources or voltage dividers), the forward voltage difference between LM561B Plus (2.95V) and LM561C (2.75V-2.8V) must be evaluated for circuit compatibility.

Q: Which substitute part offers the best thermal performance?

A: All LM561C variants (SPMWHT541ML5XAVMS0, SPMWHT541ML5XAV0S0, SPMWHT541ML5XAVKS0) offer superior thermal performance with 12°C/W thermal resistance compared to 15°C/W for both LM561B Plus variants. The 3°C/W improvement in thermal resistance results in lower junction temperature under identical operating conditions, extending component lifespan and improving reliability in thermally constrained applications.

Q: Which substitute part has the highest inventory availability?

A: SPMWHT541ML5XAVMS0 (LM561C series) has the highest inventory availability with 73,676 units in stock. This part also offers improved thermal performance (12°C/W), higher luminous efficiency (181 lm/W), and Active product status. It represents the optimal choice for procurement when forward voltage tolerance (2.8V typical) is acceptable in the application.
