Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WAUHSD is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color and CCT: White, Warm 3500K (exact match required)
• Forward Voltage (Vf): 2.95V nominal (maintains circuit compatibility)
• Test Current: 65mA (baseline operating point)
• Maximum Current Rating: Must equal or exceed 150mA
• Viewing Angle: 120° (optical performance requirement)
• Package Type: 4-SMD surface mount configuration
• Supplier Device Package: 5630 form factor
• Physical Dimensions: 5.00mm × 3.00mm footprint
• CRI: 80 (color rendering specification)

Secondary Compatibility Factors:

• Thermal Resistance: 16°C/W or lower (thermal management)
• Moisture Sensitivity Level: 2A classification
• RoHS Compliance: Required for regulatory alignment

The SPMWHT541MP5WAU0S5 qualifies as a direct substitute based on matching all primary criteria while offering improved performance characteristics in the LM561B Plus variant.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The SPMWHT541MP5WAU0S5 is the qualified substitute for SPMWHT541MD5WAUHSD. Both components share identical electrical operating parameters (2.95V forward voltage, 65mA test current, 3500K color temperature, 80 CRI, 120° viewing angle) and mechanical footprint (5630 package, 5.00mm × 3.00mm dimensions). The substitute operates within the same circuit design without modification.

Compliance and Product Status Considerations:

The main part carries "Not For New Designs" status, indicating Samsung has transitioned this component to end-of-life. The SPMWHT541MP5WAU0S5 holds "Active" product status with ROHS3 compliance, representing the current production equivalent. Organizations planning new designs or long-term deployments should adopt the substitute component.

Performance Advantages of the Substitute:

The SPMWHT541MP5WAU0S5 delivers measurable improvements: 34 lumens versus 33 lumens at 25°C (3% increase), 177 lm/W versus 172 lm/W efficiency (2.9% improvement), maximum current rating of 180mA versus 150mA (20% higher headroom), and thermal resistance of 15°C/W versus 16°C/W (6.3% better heat dissipation). These enhancements occur within identical electrical operating points, ensuring drop-in compatibility.

Packaging and Handling:

Both components use 4-SMD surface mount configuration with 5630 supplier device package designation. The substitute exhibits a lower seated height (0.80mm versus 0.90mm), which may provide clearance advantages in space-constrained applications. Moisture sensitivity classification remains identical at 2A (4 Weeks), requiring equivalent storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAU0S5 replace SPMWHT541MD5WAUHSD in existing circuit designs?

A: Yes. Both components operate at identical forward voltage (2.95V), test current (65mA), color temperature (3500K), and viewing angle (120°). The substitute integrates into existing designs without circuit modification or recalibration.

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

A: Both designations refer to 4-SMD surface mount configurations with flat lead geometry suitable for reflow soldering. The substitute's flat lead design is mechanically and electrically compatible with the main part's exposed pad configuration within the 5630 package footprint.

Q: Does the higher maximum current rating (180mA vs. 150mA) affect circuit operation?

A: No. The substitute's higher maximum current rating provides additional design margin and thermal headroom. At the specified test current of 65mA, both components operate identically. The higher rating does not alter operating voltage, light output, or color characteristics at standard operating points.

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

A: This designation indicates Samsung has transitioned the SPMWHT541MD5WAUHSD to end-of-life status. The SPMWHT541MP5WAU0S5 represents the active production equivalent with enhanced specifications and extended availability. New designs should specify the substitute component.

Q: Are there thermal management differences between the two parts?

A: The substitute exhibits superior thermal performance with 15°C/W thermal resistance versus 16°C/W in the main part. This 6.3% improvement, combined with the lower seated height (0.80mm vs. 0.90mm), enhances heat dissipation in thermally constrained applications. Both components maintain identical operating temperature ranges.

Q: What is the significance of ROHS3 compliance on the substitute?

A: ROHS3 compliance represents an enhanced regulatory standard compared to standard RoHS certification on the main part. This indicates the substitute meets current environmental and hazardous substance restrictions, supporting compliance with evolving regulatory requirements in target markets.

Q: Can these components be used interchangeably in high-volume production?

A: Yes. Identical electrical parameters, mechanical footprint, and surface mount configuration enable direct substitution in production environments. The substitute's active product status and higher availability (3192 pcs in stock versus 736 pcs) support sustained production requirements.

Q: What storage conditions apply to both components?

A: Both components carry MSL 2A (4 Weeks) classification, requiring storage at controlled temperature and humidity. Moisture sensitivity protocols are identical, and both components must be handled according to standard ESD precautions for semiconductor devices.
