Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MD5WAVHSB is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Color and CCT: White, Warm 3000K
• Forward Voltage (Vf): 2.95V typical
• Test Current: 65mA
• Viewing Angle: 120°
• Package Type: 4-SMD, 5630 form factor
• Mounting Type: Surface Mount
• CRI: 80
• Thermal Resistance: 16°C/W
• MSL Rating: 2A (4 Weeks)

Allowable Variation Parameters:

• Flux output (lumens): Within acceptable tolerance range for warm white 3000K LEDs at 65mA test current
• Lumens/Watt efficiency: Performance improvement acceptable
• Current - Max: May increase with improved design
• Height - Seated: Minor dimensional variation acceptable within package constraints
• Product Status: Active status preferred for new applications
• RoHS Compliance: ROHS3 acceptable as enhancement to RoHS Compliant

The SPMWHT541MP5WAVMS4 qualifies as a direct substitute based on these parameters while offering enhanced performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs Using SPMWHT541MD5WAVHSB:

The SPMWHT541MP5WAVMS4 is a direct functional substitute. Both components share identical electrical operating parameters (2.95V forward voltage, 65mA test current, 120° viewing angle) and thermal characteristics (16°C/W). The substitute maintains 3000K warm white color temperature and 80 CRI specification, ensuring color consistency in lighting applications.

Product Status Consideration:

The main part carries "Not For New Designs" status, indicating limited future availability and support. The substitute part SPMWHT541MP5WAVMS4 holds "Active" product status with significantly higher inventory availability (50,200 pcs vs. 1,124 pcs), providing supply chain security and long-term design continuity.

Performance Enhancement:

The substitute delivers measurable performance improvements: +3 lumens output (32lm vs. 29lm) and +16 lm/W efficiency gain (167 lm/W vs. 151 lm/W) at identical test conditions. Maximum current rating increases from 150mA to 180mA, providing additional operational headroom. Height reduction of 0.10mm (0.80mm vs. 0.90mm) may benefit space-constrained PCB layouts.

Compliance and Reliability:

Both components meet RoHS requirements. The substitute achieves ROHS3 compliance, representing enhanced environmental and regulatory alignment. Identical MSL 2A rating (4 weeks) and thermal resistance ensure equivalent handling and thermal management requirements.

Package Consideration:

The main part features flat lead with exposed pad; the substitute uses flat leads without exposed pad. This represents a minor package variation within the 5630 form factor. PCB layout compatibility depends on specific pad design; verification of thermal pad requirements is necessary for applications requiring direct thermal coupling to the substrate.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 replace SPMWHT541MD5WAVHSB in existing production?

A: Yes. Both components operate at identical electrical specifications (2.95V, 65mA, 120° viewing angle) and deliver the same 3000K warm white color with 80 CRI. The substitute is electrically and optically interchangeable. PCB layout verification is required only if the design utilizes the exposed thermal pad of the main part for direct substrate heat transfer.

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

A: The main part includes an exposed thermal pad on the package bottom for enhanced heat dissipation to the PCB substrate. The substitute uses standard flat leads without this exposed pad. Both packages maintain identical 16°C/W thermal resistance rating. Applications requiring direct thermal coupling to substrate should verify that the substitute's thermal performance meets design requirements through alternative heat path management.

Q: Why does the substitute have higher lumen output at the same test current?

A: The SPMWHT541MP5WAVMS4 represents an enhanced variant within the LM561B Plus series, incorporating improved LED die and phosphor technology. This delivers +3 lumens (32lm vs. 29lm) and +16 lm/W efficiency improvement while maintaining identical forward voltage and test current specifications. This performance gain is a direct benefit of the newer design generation.

Q: Is the 0.10mm height difference significant?

A: The substitute is 0.10mm lower in profile (0.80mm vs. 0.90mm). This minor reduction may provide benefit in space-constrained applications but does not affect electrical or optical performance. Standard PCB assembly processes accommodate this variation without modification.

Q: What does "Active" product status mean compared to "Not For New Designs"?

A: "Active" status indicates the component is in full production with long-term manufacturer support and availability commitment. "Not For New Designs" indicates the component is in mature phase with limited future support and potential discontinuation. For new designs or long-term production, the Active status substitute ensures supply chain continuity and manufacturer support.

Q: Are the RoHS compliance levels interchangeable?

A: Yes. ROHS3 compliance represents an enhanced version of RoHS Compliant status, meeting additional environmental and regulatory requirements. Designs specifying RoHS Compliant components can use ROHS3 compliant substitutes without restriction.

Q: What is the inventory advantage of the substitute?

A: The substitute has 50,200 pcs in stock compared to 1,124 pcs for the main part. This 45x inventory advantage provides significant supply security for production scaling and long-term component availability.

Q: Can I use the substitute in designs requiring maximum current operation?

A: Yes. The substitute supports 180mA maximum current compared to 150mA for the main part. This provides additional operational headroom. However, designs must operate within the original 65mA test current specification to maintain color temperature and lumen output consistency.
