Substitute Part Grouping Explanation

Substitution logic for SPMWHT541ML5XAQGS0 is based on the following criteria:

Parametric Equivalents maintain identical electrical performance and mechanical compatibility:

• Same series (LM561C) or functionally equivalent series
• Identical CCT (5700K)
• Identical color (White, Cool)
• Identical flux output (37 lm at 65mA test current)
• Identical forward voltage (2.75V typical)
• Identical package format (5630, 4-SMD, Flat Leads)
• Identical mechanical dimensions (5.00mm × 3.00mm, 0.80mm height)
• Identical thermal resistance (12°C/W)
• Identical viewing angle (120°)
• RoHS compliance maintained

Functional Substitutes provide equivalent lighting performance with acceptable parameter variations:

• Same CCT (5700K) and color (White, Cool)
• Same package format (5630, 4-SMD, Flat Leads)
• Same mechanical dimensions and mounting type
• Flux output within acceptable range for the application category
• Forward voltage within typical operating range
• CRI maintained at 80 or higher
• Viewing angle maintained at 120°

All substitute relationships are restricted to parts manufactured by Samsung Semiconductor, Inc., with identical packaging (Tape & Reel) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

SPMWHT541ML5XAQKS6, SPMWHT541ML5XAQ0S6, and SPMWHT541ML5XAQMS6 are parametric equivalents of SPMWHT541ML5XAQGS0. All three parts are classified as Active products, ensuring ongoing availability and manufacturing support. These parts maintain identical electrical specifications (2.75V forward voltage, 37 lm flux output, 207 lm/W efficiency), mechanical dimensions (5630 package, 5.00mm × 3.00mm), and thermal characteristics (12°C/W). All equivalents are RoHS Compliant with identical MSL ratings (2A, 4 Weeks). Selection among these three equivalents may be based on inventory availability or supply chain considerations, as they are functionally interchangeable.

For Functional Substitution:

SPMWHT541MP5WAQKS4 (LM561B Plus series) is a functional substitute suitable for applications where minor performance variations are acceptable. This part maintains the same 5700K CCT, 120° viewing angle, and identical package format. Key differences include: forward voltage of 2.95V (versus 2.75V), flux output of 34 lm (versus 37 lm), maximum current of 180mA (versus 200mA), and thermal resistance of 15°C/W (versus 12°C/W). The substitute delivers 177 lm/W efficiency compared to 207 lm/W. This part is Active and ROHS3 Compliant. Substitution is appropriate for applications where the 8% reduction in flux output and 3% increase in forward voltage do not impact system performance requirements.

Compliance Considerations:

All recommended parts maintain RoHS compliance. The main part and parametric equivalents are RoHS Compliant; the functional substitute is ROHS3 Compliant. Both compliance levels are acceptable for equivalent component selection. MSL rating (2A, 4 Weeks) is identical across all parts, requiring identical moisture control and storage protocols.

Frequently Asked Questions (FAQ)

Q: What is the difference between parametric equivalents and functional substitutes?

A: Parametric equivalents (SPMWHT541ML5XAQKS6, SPMWHT541ML5XAQ0S6, SPMWHT541ML5XAQMS6) maintain identical electrical and mechanical specifications to the main part SPMWHT541ML5XAQGS0. They are direct replacements with no performance variation. Functional substitutes (SPMWHT541MP5WAQKS4) provide equivalent lighting functionality with acceptable parameter variations, such as slightly lower flux output or higher forward voltage, and are suitable when minor performance differences do not affect system requirements.

Q: Can SPMWHT541MP5WAQKS4 be used as a direct replacement for SPMWHT541ML5XAQGS0?

A: SPMWHT541MP5WAQKS4 is a functional substitute, not a parametric equivalent. It differs in forward voltage (2.95V vs. 2.75V), flux output (34 lm vs. 37 lm), maximum current (180mA vs. 200mA), and thermal resistance (15°C/W vs. 12°C/W). Direct replacement is possible only if the application tolerates these variations. For applications requiring identical performance, use parametric equivalents SPMWHT541ML5XAQKS6, SPMWHT541ML5XAQ0S6, or SPMWHT541ML5XAQMS6.

Q: Why is the main part SPMWHT541ML5XAQGS0 marked "Not For New Designs"?

A: Parts marked "Not For New Designs" are typically being phased out or have been superseded. All recommended parametric equivalents are classified as Active, ensuring continued manufacturing support and availability. For new designs, select from the Active parametric equivalents: SPMWHT541ML5XAQKS6, SPMWHT541ML5XAQ0S6, or SPMWHT541ML5XAQMS6.

Q: Are all substitute parts in the same 5630 package?

A: Yes. All parts listed—the main part and all equivalents and substitutes—use the 5630 package format with 4-SMD, Flat Leads configuration. Mechanical dimensions are identical (5.00mm × 3.00mm, 0.80mm seated height), ensuring compatibility with existing PCB layouts and assembly processes.

Q: What is the impact of the 0.20V forward voltage difference between the main part and SPMWHT541MP5WAQKS4?

A: The forward voltage difference (2.75V vs. 2.95V) affects circuit design and power consumption. At 65mA test current, the substitute requires approximately 7.2% more voltage. This difference must be evaluated against the power supply design and current-limiting circuit specifications. For applications with tight voltage margins or fixed current sources, parametric equivalents with identical 2.75V forward voltage are recommended.

Q: Do all parts have the same moisture sensitivity requirements?

A: Yes. All parts—main, equivalents, and substitutes—carry MSL rating 2A (4 Weeks), requiring identical moisture control protocols. Parts must be stored in dry conditions and used within 4 weeks of opening the moisture barrier bag. Reflow soldering must follow IPC standards for MSL 2A components.

Q: Can inventory availability influence the selection between parametric equivalents?

A: Yes. SPMWHT541ML5XAQKS6 (1117 Pcs), SPMWHT541ML5XAQ0S6 (766 Pcs), and SPMWHT541ML5XAQMS6 (838 Pcs) are all parametric equivalents with identical performance. Selection may be based on inventory levels, lead times, or supply chain logistics, as they are functionally interchangeable. The functional substitute SPMWHT541MP5WAQKS4 has higher inventory (16110 Pcs) but should only be selected if performance variations are acceptable.
