Engineering Selection Recommendations

SPMWHT541MP5WAVMS5 (Recommended Primary Substitute)

This part is the direct equivalent within the LM561B Plus series and maintains identical electrical specifications to the main part. It is classified as Active product status, ensuring long-term availability and supply chain continuity. The forward voltage remains at 2.95V, eliminating circuit redesign requirements. Thermal resistance improves to 15°C/W, providing enhanced thermal performance. RoHS3 compliance represents an upgrade from RoHS Compliant status. This part is suitable for direct replacement in existing designs without modification.

SPMWHT541ML5XAVMS0 (Recommended Secondary Substitute)

This LM561C series part offers the best balance of performance and availability. Forward voltage is 2.8V, representing a 0.15V reduction from the main part—within acceptable design margin for most applications. Thermal resistance improves significantly to 12°C/W. Lumens/Watt efficiency increases to 181 lm/W. Active product status ensures supply continuity. RoHS compliance is maintained. This part is suitable for new designs and redesigns where forward voltage tolerance permits.

SPMWHT541ML5XAV0S0 and SPMWHT541ML5XAVKS0 (Alternative Substitutes)

Both parts are LM561C series equivalents with identical specifications. Forward voltage is 2.75V, representing a 0.20V reduction from the main part. Thermal resistance is 12°C/W. Lumens/Watt efficiency is 185 lm/W. Both are Active product status. These parts are suitable for applications where forward voltage tolerance permits the 0.20V reduction. Inventory availability differs: SPMWHT541ML5XAV0S0 has 969 pcs in stock; SPMWHT541ML5XAVKS0 has 881 pcs in stock.

Substitution Constraints:

Forward voltage variation must be evaluated against circuit design margins. The main part operates at 2.95V; LM561C variants operate at 2.75V or 2.8V. Designs with tight voltage regulation or current-limiting resistor calculations must account for this 0.15V to 0.20V reduction. Thermal resistance improvements in LM561C variants reduce junction temperature rise, which may require thermal design review in high-power applications.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP5WAVMS5 be used as a direct drop-in replacement for SPMWHT541MP5WAVHSD?

A: Yes. SPMWHT541MP5WAVMS5 is a direct equivalent within the LM561B Plus series. All electrical parameters, forward voltage (2.95V), test current (65mA), flux output (34 lm), and mechanical dimensions are identical or compatible. The primary difference is product status (Active vs. Not For New Designs) and improved thermal resistance (15°C/W vs. 16°C/W). No circuit modification is required.

Q2: What is the difference between LM561B Plus and LM561C series substitutes?

A: LM561B Plus and LM561C are different LED series within Samsung's portfolio. The main part uses LM561B Plus; substitute parts SPMWHT541ML5XAV0S0, SPMWHT541ML5XAVKS0, and SPMWHT541ML5XAVMS0 use LM561C. Both series share identical package (5630), color (3000K warm white), CRI (80), and viewing angle (120°). The primary difference is forward voltage: LM561B Plus operates at 2.95V; LM561C operates at 2.75V or 2.8V. LM561C variants offer improved thermal resistance (12°C/W vs. 16°C/W) and higher lumens/watt efficiency (181–185 lm/W vs. 172 lm/W).

Q3: Is the 0.20V forward voltage difference between SPMWHT541MP5WAVHSD (2.95V) and SPMWHT541ML5XAV0S0 (2.75V) acceptable?

A: Forward voltage difference of 0.20V is within typical design tolerance for LED applications. However, acceptance depends on circuit design specifics. If the design uses a current-limiting resistor, the lower forward voltage will result in slightly higher LED current (approximately 3% increase at 65mA nominal). If the design uses a constant-current driver, forward voltage variation is compensated automatically. Circuit designers must evaluate voltage headroom and current regulation capability before substitution.

Q4: Why do LM561C variants show higher lumens/watt efficiency than the main part?

A: LM561C variants (181–185 lm/W) demonstrate higher efficiency than LM561B Plus (172 lm/W) due to improved LED die technology and manufacturing process. This is a generational improvement within Samsung's LED product line. Higher efficiency results in lower power dissipation and reduced thermal load, which is reflected in the improved thermal resistance (12°C/W vs. 16°C/W).

Q5: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts use identical packaging: 4-SMD, Flat Leads, 5630 supplier device package, with dimensions 5.00mm × 3.00mm and maximum seated height 0.80mm. All parts are supplied in Tape & Reel (TR) format. No PCB layout or assembly process modification is required.

Q6: What is the inventory status of substitute parts?

A: SPMWHT541MP5WAVMS5 has the highest inventory (26,898 pcs), ensuring immediate availability. SPMWHT541ML5XAVMS0 has 73,676 pcs in stock. SPMWHT541ML5XAV0S0 has 969 pcs, and SPMWHT541ML5XAVKS0 has 881 pcs. The main part SPMWHT541MP5WAVHSD has 1,034 pcs remaining inventory. For long-term supply continuity, SPMWHT541MP5WAVMS5 or SPMWHT541ML5XAVMS0 are recommended.

Q7: Do all parts meet RoHS compliance requirements?

A: Yes. The main part is RoHS Compliant. SPMWHT541MP5WAVMS5 is ROHS3 Compliant (upgraded standard). All LM561C variants (SPMWHT541ML5XAV0S0, SPMWHT541ML5XAVKS0, SPMWHT541ML5XAVMS0) are RoHS Compliant. All parts meet environmental and regulatory requirements for EU and global markets.

Q8: What is the Moisture Sensitivity Level (MSL) for all parts?

A: All parts are rated MSL 2A (4 Weeks). This indicates the component can be exposed to ambient conditions (23°C ± 2°C, 45% ± 5% RH) for up to 4 weeks before requiring baking. After 4 weeks of exposure, components must be baked at 125°C for 24 hours before reflow soldering. This specification is identical across all parts.

Q9: Can SPMWHT541ML5XAVMS0 be used in new designs?

A: Yes. SPMWHT541ML5XAVMS0 is classified as Active product status, making it suitable for new designs. It offers improved thermal performance (12°C/W), higher efficiency (181 lm/W), and forward voltage of 2.8V. Circuit designers must account for the 0.15V forward voltage reduction compared to the main part. This part is recommended for new designs requiring warm white 3000K LEDs in 5630 package format.

Q10: What thermal considerations apply when substituting LM561C variants?

A: LM561C variants have thermal resistance of 12°C/W compared to 16°C/W for the main part. This 4°C/W improvement reduces junction temperature rise by approximately 0.26°C at 65mA operation. In high-power applications or thermally constrained designs, this improvement is beneficial. However, if the original design includes thermal management features (heat sinks, thermal vias) sized for 16°C/W, these features remain effective with LM561C variants and provide additional thermal margin.
