Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541ML5XAVNS0 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color and CCT: White, Warm 3000K (exact match required)
• Package Type: 4-SMD, Flat Leads 5630 form factor (mechanical compatibility)
• Viewing Angle: 120° (optical performance)
• Mounting Type: Surface Mount (assembly compatibility)
• Dimensions: 5.00mm × 3.00mm footprint (PCB layout compatibility)

Acceptable Variation Parameters:

• Forward Voltage (Vf): Tolerance within typical circuit design margins
• Flux Output: Functional equivalence within application brightness requirements
• Maximum Current Rating: Equal or higher rating acceptable
• Thermal Resistance: Acceptable within thermal management design
• CRI: Maintained at 80 or higher for color quality consistency

The SPMWHT541MP5WAVMS4 qualifies as a substitute based on matching all primary criteria while operating within acceptable variation ranges for secondary parameters.

Engineering Selection Recommendations

Primary Recommendation: SPMWHT541MP5WAVMS4

The SPMWHT541MP5WAVMS4 is the qualified substitute for SPMWHT541ML5XAVNS0 based on the following engineering factors:

1. Product Status Alignment: The substitute part carries Active product status, ensuring long-term availability and supply chain stability. The main part is designated "Not For New Designs," making substitution necessary for ongoing production support.

2. Regulatory Compliance: Both parts maintain RoHS compliance. The substitute achieves ROHS3 certification, meeting current regulatory requirements for new component procurement.

3. Mechanical Compatibility: Identical 5630 package footprint (5.00mm × 3.00mm) and 4-SMD flat lead configuration ensure direct PCB layout compatibility without redesign.

4. Optical Performance: Both parts maintain 120° viewing angle and 80 CRI, preserving optical characteristics for lighting applications.

5. Electrical Compatibility: Forward voltage difference of 0.20V (2.75V vs. 2.95V) falls within acceptable circuit design tolerance for typical LED driver circuits. Flux output difference of 3 lumens (35 lm vs. 32 lm) represents 8.6% variance, acceptable for most general illumination applications.

6. Thermal Characteristics: Thermal resistance increase from 12°C/W to 16°C/W requires verification within specific thermal management designs but remains within acceptable parameters for standard surface mount applications.

7. Moisture Sensitivity: Identical MSL 2A rating (4 Weeks) maintains equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 be used as a direct replacement for SPMWHT541ML5XAVNS0 without circuit modification?

A: The substitute part is mechanically and optically compatible for direct PCB placement. However, the 0.20V forward voltage increase requires circuit verification. LED driver circuits with fixed current regulation will operate correctly. Circuits with series resistors may require recalculation to maintain target brightness levels.

Q: What is the brightness difference between these two parts?

A: At 65mA test current, the main part produces 35 lumens while the substitute produces 32 lumens. This 3-lumen difference (8.6% reduction) is typical for LED technology variations and acceptable for most general illumination applications. Applications requiring specific brightness levels should conduct photometric testing.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 5630 package with identical dimensions: 5.00mm length × 3.00mm width × 0.80mm maximum height. PCB footprints are directly compatible.

Q: What is the significance of the product status change from "Not For New Designs" to "Active"?

A: The main part has reached end-of-life and is no longer recommended for new product development. The substitute part is in active production with guaranteed long-term availability, making it suitable for both new designs and replacement applications.

Q: Do both parts have the same color rendering index?

A: Yes. Both parts maintain CRI 80, ensuring equivalent color rendering performance for warm white 3000K lighting applications.

Q: What is the maximum current difference, and does it affect substitution?

A: The main part supports 200mA maximum while the substitute supports 180mA maximum. For applications operating at or below 65mA test current, this difference is not a limiting factor. Applications requiring operation above 180mA cannot use the substitute part.

Q: Are there any moisture sensitivity differences?

A: No. Both parts carry identical MSL 2A rating (4 Weeks), requiring the same handling, storage, and reflow procedures.

Q: How does the thermal resistance difference affect thermal management?

A: The substitute part has 4°C/W higher thermal resistance (16°C/W vs. 12°C/W). In high-ambient-temperature applications or designs with limited thermal dissipation, this may result in higher junction temperatures. Thermal analysis should be conducted for applications operating above 85°C ambient temperature.
