Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP5WARUS4 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• 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°

Mechanical Parameters (Must Match):

• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Size / Dimension: 5.00 × 3.00 mm
• Height - Seated (Max): 0.80 mm
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• MSL: 2A (4 Weeks)
• ECCN: EAR99
• HTSUS: 8541.41.0000

Variable Parameters (Allowed to Differ):

• Packaging format: Tape & Reel (TR), Cut Tape (CT), or Cut Tape & Digi-Reel®
• Product Status: Not For New Designs or Active
• Thermal Resistance: 14–15°C/W
• Inventory availability

All five substitute parts meet these equivalence criteria and are direct functional replacements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes for Active Designs:

For new designs or ongoing production requiring active product status, SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, SPMWHT541MP5WARMS4, SPMWHT541MP5WARNS4, and SPMWHT541MP5WARSS4 are all qualified equivalents. All substitute parts maintain identical electrical performance, mechanical compatibility, and compliance certifications.

Packaging Considerations:

• SPMWHT541MP5WAR0S4: Cut Tape (CT) & Digi-Reel® format provides flexibility for both manual and automated assembly processes with high inventory availability (500,300 pcs).
• SPMWHT541MP5WARKS4: Cut Tape (CT) format suitable for lower-volume or manual pick-and-place operations (73,313 pcs available).
• SPMWHT541MP5WARMS4, SPMWHT541MP5WARNS4, SPMWHT541MP5WARSS4: Tape & Reel (TR) format optimized for high-speed automated assembly lines.

Compliance Status:

Five of six substitute parts carry ROHS3 Compliant certification, representing the latest regulatory standard. SPMWHT541MP5WARNS4 maintains RoHS Compliant status. All parts meet REACH, ECCN EAR99, and HTSUS 8541.41.0000 requirements.

Thermal Performance:

SPMWHT541MP5WARSS4 offers marginally improved thermal resistance at 14°C/W compared to 15°C/W in other variants, providing enhanced heat dissipation capability in thermally constrained applications.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WARUS4 be directly replaced with any of the substitute parts?

A: Yes. All five substitute parts are parametric equivalents with identical electrical specifications (2.95V forward voltage, 65mA test current, 34 lm flux, 5000K CCT, 80 CRI), mechanical dimensions (5630 package, 5.00 × 3.00 mm, 0.80 mm height), and compliance certifications. Substitution is valid at the component level.

Q: What is the difference between the packaging formats?

A: Packaging format affects supply chain and assembly logistics only. Tape & Reel (TR) is standard for high-volume automated assembly. Cut Tape (CT) suits lower volumes and manual assembly. Cut Tape & Digi-Reel® combines both capabilities. All formats contain electrically and mechanically identical components.

Q: Why is SPMWHT541MP5WARUS4 marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. Substitute parts with "Active" status are recommended for new designs to ensure long-term supply availability and continued manufacturer support.

Q: Are there any thermal differences between substitutes?

A: SPMWHT541MP5WARSS4 has thermal resistance of 14°C/W versus 15°C/W for other variants. This 1°C/W difference is negligible in most applications but may provide marginal benefit in high-power or thermally constrained designs.

Q: Do all substitutes meet the same compliance standards?

A: Five substitutes carry ROHS3 Compliant certification. SPMWHT541MP5WARNS4 carries RoHS Compliant status. Both certifications are valid. All parts meet REACH, ECCN EAR99, and HTSUS requirements identically.

Q: Which substitute offers the best inventory availability?

A: SPMWHT541MP5WAR0S4 has the highest inventory (500,300 pcs), followed by SPMWHT541MP5WARKS4 (73,313 pcs). For immediate availability in Tape & Reel format, SPMWHT541MP5WARMS4 (19,382 pcs) and SPMWHT541MP5WARSS4 (1,150 pcs) are options.

Q: Can substitutes be mixed in the same production batch?

A: Yes. All substitutes are electrically and mechanically identical. Mixing is permissible from a functional standpoint, though single-part-number procurement is recommended for traceability and supply chain management.
