Substitute Part Grouping Explanation

Substitution of SPMWHT541MP5WARHS4 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for direct substitution:

Fixed Equivalence Parameters:

• Series: LM561B Plus
• Color: White, Cool
• CCT: 5000K
• Flux @ 25°C, 65mA: 34 lm (33–35 lm range)
• Forward Voltage (Vf): 2.95V
• Test Current: 65mA
• Maximum Current: 180mA
• Lumens/Watt: 177 lm/W
• CRI: 80
• Viewing Angle: 120°
• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Physical Dimensions: 5.00mm × 3.00mm
• Height - Seated (Max): 0.80mm
• Mounting Type: Surface Mount
• MSL: 2A (4 Weeks)

Variable Parameters Allowing Substitution:

• Packaging format (Tape & Reel, Cut Tape, Digi-Reel®)
• Thermal Resistance of Package (14–16°C/W range)
• Product Status (Not For New Designs vs. Active)
• RoHS certification level (RoHS Compliant vs. ROHS3 Compliant)

All five substitute part numbers maintain identical electrical performance and physical form factor while differing only in packaging configuration and thermal characteristics within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs:

All five substitute part numbers (SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, SPMWHT541MP5WARMS4, SPMWHT541MP5WARNS4, SPMWHT541MP5WARSS4) are classified as Active product status and are suitable for new design implementations. The original part SPMWHT541MP5WARHS4 is designated "Not For New Designs" and should be replaced in all new applications.

Compliance Considerations:

Four of the five substitute parts (SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, SPMWHT541MP5WARMS4, SPMWHT541MP5WARSS4) carry ROHS3 Compliant certification, representing the most current regulatory compliance standard. SPMWHT541MP5WARNS4 maintains RoHS Compliant status. All parts meet REACH requirements or are REACH Unaffected.

Thermal Performance:

Substitute parts demonstrate improved thermal characteristics compared to the main part. Thermal resistance ranges from 14°C/W (SPMWHT541MP5WARSS4) to 15°C/W (SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, SPMWHT541MP5WARMS4), compared to 16°C/W for SPMWHT541MP5WARHS4. Lower thermal resistance indicates superior heat dissipation capability.

Packaging Selection:

• SPMWHT541MP5WAR0S4: Cut Tape with Digi-Reel® packaging; highest inventory availability (500,300 pcs); suitable for high-volume automated assembly
• SPMWHT541MP5WARKS4: Cut Tape packaging; 73,313 pcs available; standard for component-level procurement
• SPMWHT541MP5WARMS4: Tape & Reel packaging; 19,382 pcs available; standard for reel-based pick-and-place systems
• SPMWHT541MP5WARNS4: Tape & Reel packaging; limited inventory (793 pcs); suitable for lower-volume applications
• SPMWHT541MP5WARSS4: Tape & Reel packaging; 1,150 pcs available; optimal thermal performance with ROHS3 compliance

Direct Substitution Compatibility:

All substitute parts maintain identical electrical performance (2.95V forward voltage, 65mA test current, 34 lm flux, 177 lm/W efficiency) and physical form factor (5630 package, 5.00mm × 3.00mm, 0.80mm height). Substitution requires only packaging format adjustment in procurement and assembly processes; no circuit design modifications are necessary.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WARHS4 be directly replaced with any of the five substitute parts in existing designs?

A: Yes. All five substitute parts are parametrically equivalent to SPMWHT541MP5WARHS4 across all critical electrical and mechanical specifications. Direct substitution is possible without circuit modifications. Only the packaging format and thermal characteristics differ, which do not affect electrical performance in the application circuit.

Q: What is the difference between Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® packaging?

A: Tape & Reel (TR) is standard reel-based packaging for automated pick-and-place assembly systems. Cut Tape (CT) provides individual component strips for manual or semi-automated handling. Digi-Reel® is a specialized reel format optimized for high-speed automated assembly. All three formats contain identical components; packaging selection depends on assembly equipment and production volume requirements.

Q: Why does SPMWHT541MP5WARHS4 have "Not For New Designs" status?

A: This designation indicates the part has reached end-of-life status and Samsung Semiconductor recommends transitioning to active alternatives for new product development. All five substitute parts carry Active status and are supported for ongoing production and new designs.

Q: Are there thermal performance differences between the substitute parts?

A: Yes. Thermal resistance varies from 14°C/W (SPMWHT541MP5WARSS4) to 15°C/W (SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, SPMWHT541MP5WARMS4) compared to 16°C/W for the main part. Lower thermal resistance provides superior heat dissipation. For applications with thermal constraints, SPMWHT541MP5WARSS4 offers the best thermal performance.

Q: Which substitute part has the best inventory availability?

A: SPMWHT541MP5WAR0S4 has the highest inventory level at 500,300 pieces. This part is available in Cut Tape with Digi-Reel® packaging and carries ROHS3 Compliant certification, making it suitable for high-volume production requirements.

Q: Do all substitute parts meet current RoHS compliance standards?

A: Four of the five substitute parts (SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, SPMWHT541MP5WARMS4, SPMWHT541MP5WARSS4) carry ROHS3 Compliant certification. SPMWHT541MP5WARNS4 maintains RoHS Compliant status. Both certifications are valid; ROHS3 represents the most current regulatory standard.

Q: Can substitute parts be mixed within a single production batch?

A: Yes. All substitute parts are parametrically identical in electrical and optical performance. Mixing different packaging formats or thermal variants within a batch does not affect circuit functionality. However, assembly process parameters may require adjustment based on packaging format.

Q: What is the MSL (Moisture Sensitivity Level) for these parts?

A: All parts, including the main part and all substitutes, carry MSL 2A (4 Weeks) rating. This indicates the components must be stored in controlled humidity conditions and used within four weeks of package opening. Standard moisture-barrier packaging and desiccant storage are required.
