Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WATMS2 is determined by strict alignment of the following critical parameters:

Electrical Compatibility:

• Color and CCT: White, Neutral 4000K (fixed requirement)
• Forward Voltage: 2.95V typical (allows operation in existing circuits)
• Test Current: 65mA nominal operation point
• CRI: 80 (color rendering specification)
• Viewing Angle: 120° (optical performance)

Mechanical Compatibility:

• Package Type: 4-SMD, 5630 form factor
• Mounting: Surface Mount
• Footprint Dimensions: 5.00mm × 3.00mm
• Height: Compatible with 0.90mm maximum seated height

Regulatory & Environmental:

• RoHS Compliance status
• MSL Rating: 2A (4 Weeks)
• ECCN and HTSUS classifications

The substitute part SPMWHT541MP5WATMS4 maintains electrical equivalence through identical color temperature, forward voltage, test current, CRI, and viewing angle. Mechanical compatibility is confirmed through identical footprint dimensions and 5630 package designation. The substitute operates within the same thermal and environmental parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement:

The SPMWHT541MP5WATMS4 serves as the direct substitute for the obsolete SPMWHT541MD5WATMS2. Both components share identical electrical characteristics at the 65mA test current: 2.95V forward voltage, 4000K color temperature, 80 CRI, and 120° viewing angle. Footprint dimensions and 5630 package format are identical, enabling drop-in replacement on existing PCB layouts.

Compliance Advantage:

The substitute part carries Active product status with ROHS3 compliance, compared to the Obsolete status of the main part. This transition ensures continued regulatory alignment and supply chain sustainability for new production runs and design revisions.

Performance Enhancement:

The SPMWHT541MP5WATMS4 delivers enhanced luminous flux (33 lm versus 29 lm at 65mA) and improved efficiency (172 lm/W versus 151 lm/W). Maximum current rating increases from 150mA to 180mA, providing additional operational headroom. These improvements occur within identical electrical operating parameters, requiring no circuit modifications.

Mechanical Consideration:

The substitute part height reduces from 0.90mm to 0.80mm maximum seated height. This dimensional improvement enhances clearance margins in space-constrained applications and maintains full compatibility with existing assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WATMS4 replace SPMWHT541MD5WATMS2 without circuit modification?

A: Yes. Both parts operate at identical forward voltage (2.95V) and test current (65mA). No changes to current-limiting resistors, power supply specifications, or control circuitry are required. The substitute is electrically interchangeable at the 65mA operating point.

Q: Are the optical characteristics identical between the two parts?

A: Yes. Both parts deliver 4000K neutral white light with 80 CRI and 120° viewing angle. Color temperature, color rendering index, and beam pattern are identical. The substitute provides higher luminous flux (33 lm versus 29 lm) at the same test current, resulting in brighter output from the same circuit.

Q: What is the significance of the package lead configuration difference?

A: The main part features "Flat Lead Exposed Pad" while the substitute features "Flat Leads." Both configurations are 4-SMD, 5630 format with identical 5.00mm × 3.00mm footprints. The lead configuration difference does not affect PCB layout compatibility or soldering process parameters.

Q: Does the reduced height of the substitute part affect assembly compatibility?

A: No. The substitute height of 0.80mm maximum is lower than the main part's 0.90mm maximum. This reduction improves clearance margins and is fully compatible with existing pick-and-place equipment, reflow profiles, and assembly fixtures designed for the original part.

Q: What is the inventory and supply status difference?

A: The main part (SPMWHT541MD5WATMS2) is Obsolete with 7,100 pieces in stock. The substitute (SPMWHT541MP5WATMS4) is Active with 600,200 pieces in stock. The Active status and significantly higher inventory ensure long-term supply availability for ongoing production requirements.

Q: Are there thermal management differences between the parts?

A: No. Both parts maintain identical thermal resistance of 16°C/W. Thermal design calculations, heat sink requirements, and thermal management strategies remain unchanged when substituting the parts.

Q: What packaging format is available for the substitute part?

A: The SPMWHT541MP5WATMS4 is supplied in Tape & Reel (TR) format, the standard packaging for high-volume surface mount production. This format is compatible with automated assembly equipment and provides efficient component handling and storage.
