Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility):

SPMWHT541MP5WAVMS5 is the primary direct substitute for SPMWHT541MP5WAVKS0. Both components belong to the LM561B Plus series and share identical electrical and mechanical specifications. The primary distinction is product status: SPMWHT541MP5WAVMS5 is classified as Active, ensuring continued availability and manufacturing support. This part exhibits marginally improved efficiency (177 lm/W versus 172 lm/W) while maintaining all other parameters within specification. RoHS3 compliance of SPMWHT541MP5WAVMS5 exceeds the RoHS Compliant status of the main part, providing enhanced regulatory alignment for new production runs.

Parametric Equivalents (Series Upgrade):

SPMWHT541ML5XAVMS0, SPMWHT541ML5XAVKS0, and SPMWHT541ML5XAV0S0 represent parametric equivalents from the LM561C series. These components maintain identical flux output (33lm), CRI (80), viewing angle (120°), and all mechanical dimensions. The LM561C series demonstrates improved thermal performance (12°C/W versus 15°C/W) and superior luminous efficiency (181–185 lm/W versus 172 lm/W). Forward voltage variation (2.75–2.8V versus 2.95V) falls within acceptable operating tolerance for most circuit designs. All three LM561C variants carry Active product status, ensuring long-term supply availability.

Inventory Availability Consideration:

SPMWHT541ML5XAVMS0 offers the highest inventory availability (73,676 pcs), followed by SPMWHT541MP5WAVMS5 (26,898 pcs). For applications requiring immediate large-volume procurement, SPMWHT541ML5XAVMS0 provides optimal supply chain security while maintaining full parametric compatibility.

Compliance and Certification:

All substitute parts maintain MSL 2A (4 Weeks) moisture sensitivity classification and RoHS compliance status. SPMWHT541MP5WAVMS5 carries ROHS3 certification, representing the most current regulatory standard. Selection between RoHS Compliant and ROHS3 Compliant variants depends on end-product regulatory requirements and manufacturing timeline.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS5 be used as a direct replacement for SPMWHT541MP5WAVKS0 without PCB modification?

A: Yes. SPMWHT541MP5WAVMS5 is a direct substitute with identical package dimensions (5.00mm × 3.00mm), height (0.80mm), lead configuration (4-SMD, Flat Leads), and electrical specifications. No PCB layout changes are required. Both components are rated for 65mA test current and 180mA maximum current with matching forward voltage (2.95V) and flux output (33–34lm range).

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

A: The LM561C series offers improved thermal performance (12°C/W versus 15°C/W thermal resistance) and higher luminous efficiency (181–185 lm/W versus 172 lm/W). Forward voltage is lower in LM561C variants (2.75–2.8V versus 2.95V). All other parameters—flux output, CRI, viewing angle, package, and dimensions—remain identical. LM561C components are suitable for applications where thermal management or efficiency optimization is beneficial.

Q: Are there any forward voltage compatibility concerns when substituting LM561C parts?

A: Forward voltage variation between SPMWHT541MP5WAVKS0 (2.95V) and LM561C substitutes (2.75–2.8V) represents a 0.15–0.20V reduction. This difference is within typical LED circuit design tolerance and does not require circuit modification for constant-current driver applications. For constant-voltage designs, verify that the reduced forward voltage does not cause excessive current through current-limiting resistors. Thermal performance improvement in LM561C variants (12°C/W) may reduce junction temperature by approximately 3–5°C under identical operating conditions.

Q: Which substitute part offers the best long-term supply availability?

A: SPMWHT541ML5XAVMS0 provides the highest inventory level (73,676 pcs) and Active product status, ensuring sustained manufacturing support. SPMWHT541MP5WAVMS5 (26,898 pcs) offers the second-highest availability while maintaining LM561B Plus series continuity. Both parts are suitable for production designs requiring multi-year supply commitments.

Q: What is the significance of "Not For New Designs" status on the main part?

A: "Not For New Designs" indicates that SPMWHT541MP5WAVKS0 has reached end-of-life and Samsung Semiconductor is not recommending this part for new product development. Existing inventory may be available for legacy product support, but new designs should transition to Active-status alternatives such as SPMWHT541MP5WAVMS5 or LM561C series components to ensure long-term supply chain reliability and manufacturing support.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts meet RoHS compliance requirements. SPMWHT541MP5WAVMS5 carries ROHS3 certification (current standard), while SPMWHT541ML5XAV0S0, SPMWHT541ML5XAVKS0, and SPMWHT541ML5XAVMS0 carry RoHS Compliant status. Both certifications satisfy regulatory requirements for consumer and industrial applications in regulated markets.

Q: Can these LED components be used interchangeably in existing production equipment?

A: Yes. All substitute parts share identical 5630 package dimensions, 4-SMD flat lead configuration, and surface mount mounting type. Tape & Reel (TR) packaging is consistent across all parts. Existing pick-and-place equipment, reflow profiles, and PCB assembly processes require no modification. Component orientation and placement coordinates remain unchanged.

Q: What is the thermal resistance difference impact on circuit design?

A: LM561C variants (12°C/W) provide 3°C/W improvement over SPMWHT541MP5WAVKS0 (15°C/W). At 65mA test current, this represents approximately 0.195W power dissipation with 3–5°C lower junction temperature rise. For applications operating near thermal limits, LM561C substitutes reduce thermal stress and extend component lifespan. For standard applications, this difference is not critical to circuit performance.
