Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution:

The SPMWHT541MP5WAVMS4 is the qualified substitute for SPMWHT541MD5WAV0SC based on the following engineering factors:

1. Product Status Transition: The original part is classified as "Not For New Designs." The substitute SPMWHT541MP5WAVMS4 carries "Active" status, ensuring continued availability and manufacturing support.

2. Electrical Compatibility: Both parts operate at identical forward voltage (2.95V) and test current (65mA), with matching color temperature (3000K) and CRI (80). Luminous flux values fall within compatible ranges (31lm vs. 32lm at 25°C).

3. Mechanical Compatibility: Both components use identical 5630 package footprint (5.00mm × 3.00mm) and surface mount configuration. The substitute features a lower seated height (0.80mm vs. 0.90mm), which presents no clearance issues for standard PCB designs.

4. Compliance Enhancement: The substitute meets ROHS3 compliance, exceeding the RoHS Compliant status of the original part, supporting stricter regulatory requirements.

5. Performance Improvement: The substitute delivers higher luminous efficiency (167 lm/W vs. 162 lm/W) and higher maximum current rating (180mA vs. 150mA), providing design margin for thermal and electrical stress conditions.

Inventory Consideration: The substitute part maintains significantly higher stock availability (50,200 pcs vs. 750 pcs), supporting production continuity and reducing supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 be used as a direct replacement for SPMWHT541MD5WAV0SC in existing designs?

A: Yes. Both parts share identical electrical specifications (2.95V forward voltage, 65mA test current, 3000K color temperature, 80 CRI) and mechanical footprint (5630 package, 5.00mm × 3.00mm). The substitute is electrically and mechanically compatible without circuit modification.

Q: What is the difference between "Flat Lead Exposed Pad" and "Flat Leads" package configurations?

A: Both configurations are 4-SMD surface mount packages with identical footprints and electrical performance. The difference is in lead frame design. "Flat Lead Exposed Pad" includes an exposed thermal pad on the bottom surface, while "Flat Leads" uses standard lead configuration. Both are compatible with standard reflow soldering processes.

Q: Why does the substitute part have a lower seated height (0.80mm vs. 0.90mm)?

A: The reduced height represents a manufacturing improvement in the LM561B Plus series. This does not affect compatibility; components with lower profiles present no clearance conflicts in standard PCB designs and may provide benefits for space-constrained applications.

Q: Is the higher maximum current rating (180mA vs. 150mA) of the substitute part significant?

A: The higher maximum current rating provides additional design margin and thermal headroom. If the original design operates at or near 150mA, the substitute offers improved reliability and reduced thermal stress. Standard operation at 65mA test current remains identical between both parts.

Q: What does "Not For New Designs" status mean for the original part?

A: This designation indicates the SPMWHT541MD5WAV0SC has reached end-of-life and Samsung Semiconductor is not recommending it for new product development. Existing inventory may be available for legacy support, but the active substitute SPMWHT541MP5WAVMS4 is the recommended choice for all new designs and ongoing production.

Q: Are there any thermal performance differences between the two parts?

A: Both parts maintain identical thermal resistance (16°C/W). Thermal performance is equivalent under identical operating conditions and PCB thermal design.

Q: What is the significance of ROHS3 compliance versus RoHS Compliant status?

A: ROHS3 represents the current regulatory standard with stricter material restrictions. The substitute's ROHS3 compliance ensures compatibility with current and future regulatory requirements, while the original part's RoHS Compliant status meets earlier standards. Both are compliant; ROHS3 represents a higher standard.

Q: Can the substitute part be used in applications requiring the exact original part number?

A: Component selection should be based on electrical and mechanical specifications rather than part number alone. The substitute meets all functional requirements. However, design documentation and procurement specifications should be updated to reflect the new part number SPMWHT541MP5WAVMS4 to ensure proper inventory management and traceability.
