Substitute Part Grouping Explanation

Substitute parts for SPMWHT541MP5WAVGS5 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitute (Same Series): SPMWHT541MP5WAVMS4 is a direct substitute within the LM561B Plus series. This part maintains identical electrical specifications (2.95V Vf, 65mA test current, 3000K CCT, 80 CRI) and mechanical parameters (5630 package, 4-SMD flat leads, 120° viewing angle, 5.00mm x 3.00mm dimensions). The primary difference is product status (Active vs. Not For New Designs) and improved thermal resistance (16°C/W vs. 20°C/W). This part is suitable for direct replacement in existing designs.

Parametric Equivalents (Different Series): SPMWH1228FD5W2V0SJ, SPMWH1228FD5W2VKSJ, and SPMWH1228FD5W2VMSJ are LM281B+ series parts that provide parametric equivalence based on the following criteria:

• Color and CCT: All maintain White, Warm 3000K specification
• Package and Mounting: Identical 5630 package, 4-SMD flat leads, surface mount configuration
• Mechanical Dimensions: Identical 5.00mm x 3.00mm footprint and 0.80mm maximum height
• Viewing Angle: Maintained at 120°
• CRI: Maintained at 80
• Compliance: All are ROHS3 Compliant (vs. RoHS Compliant for main part)

Key electrical differences in parametric equivalents: Forward voltage is 2.9V (vs. 2.95V), test current is 150mA (vs. 65mA), and maximum current is 200mA (vs. 180mA). Thermal resistance is 25°C/W (vs. 20°C/W). These parts are suitable for applications where the higher test current and different thermal characteristics are acceptable within circuit design parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Series Continuity): SPMWHT541MP5WAVMS4 is the primary substitute for SPMWHT541MP5WAVGS5. Both parts belong to the LM561B Plus series and maintain identical electrical and mechanical specifications. SPMWHT541MP5WAVMS4 carries Active product status, ensuring long-term availability and supply chain continuity. The improved thermal resistance (16°C/W vs. 20°C/W) provides enhanced thermal performance. Both parts meet RoHS compliance requirements (ROHS3 for the substitute vs. RoHS for the original). This part is suitable for new production runs and design updates requiring direct compatibility.

For Parametric Equivalence (Series Migration): SPMWH1228FD5W2V0SJ, SPMWH1228FD5W2VKSJ, and SPMWH1228FD5W2VMSJ are LM281B+ series alternatives suitable when circuit design parameters accommodate the following electrical variations:

• Forward voltage tolerance: 2.9V (vs. 2.95V) represents a 0.05V reduction
• Test current specification: 150mA (vs. 65mA) indicates higher operational current rating
• Maximum current rating: 200mA (vs. 180mA)
• Thermal resistance: 25°C/W (vs. 20°C/W) requires thermal design verification

All three LM281B+ variants are Active products with ROHS3 Compliant status and identical mechanical compatibility (5630 package, 5.00mm x 3.00mm footprint, 0.80mm height). Selection among these three variants depends on inventory availability and supply chain requirements, as they share identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAVMS4 be used as a direct drop-in replacement for SPMWHT541MP5WAVGS5?

A: Yes. SPMWHT541MP5WAVMS4 maintains identical electrical specifications (2.95V Vf, 65mA test current, 3000K CCT, 80 CRI) and mechanical parameters (5630 package, 4-SMD flat leads, 5.00mm x 3.00mm dimensions, 0.80mm height). Both parts are surface mount with 120° viewing angle. The substitute has improved thermal resistance (16°C/W vs. 20°C/W) and Active product status, making it suitable for direct replacement in existing PCB designs without layout modifications.

Q: What are the key differences between the LM561B Plus and LM281B+ series substitutes?

A: The primary differences are test current specification (65mA for LM561B Plus vs. 150mA for LM281B+), forward voltage (2.95V vs. 2.9V), and thermal resistance (20°C/W vs. 25°C/W for the main part). All other parameters—color, CCT, CRI, package type, dimensions, and viewing angle—remain identical. The LM281B+ series represents a different LED die technology with higher current rating and different thermal characteristics.

Q: Are the three LM281B+ variants (SPMWH1228FD5W2V0SJ, SPMWH1228FD5W2VKSJ, SPMWH1228FD5W2VMSJ) electrically identical?

A: Yes. All three LM281B+ variants share identical electrical specifications (2.9V Vf, 150mA test current, 200mA maximum current, 3000K CCT, 80 CRI) and mechanical parameters (5630 package, 4-SMD flat leads, 5.00mm x 3.00mm dimensions, 0.80mm height, 120° viewing angle, 25°C/W thermal resistance). Differences exist only in packaging lot codes or manufacturing batches. Selection should be based on inventory availability and supply chain logistics.

Q: What compliance certifications apply to these substitute parts?

A: SPMWHT541MP5WAVMS4 and all three LM281B+ variants are ROHS3 Compliant. The original SPMWHT541MP5WAVGS5 is RoHS Compliant. All parts carry MSL 2A (4 Weeks) moisture sensitivity rating. The LM281B+ variants include REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Q: Can I use LM281B+ parts in a circuit designed for LM561B Plus?

A: Circuit compatibility depends on design tolerance for the following parameter variations: forward voltage difference of 0.05V (2.9V vs. 2.95V), test current difference of 85mA (150mA vs. 65mA), and thermal resistance difference of 5°C/W (25°C/W vs. 20°C/W). The designer must verify that the power supply, current limiting resistors, and thermal management accommodate these specifications. Mechanical compatibility is confirmed (identical package, footprint, and height).

Q: What is the inventory status for these substitute parts?

A: SPMWHT541MP5WAVMS4 has 50,200 pieces in stock. SPMWH1228FD5W2V0SJ has 954 pieces, SPMWH1228FD5W2VKSJ has 1,134 pieces, and SPMWH1228FD5W2VMSJ has 950 pieces in stock. The direct substitute (SPMWHT541MP5WAVMS4) offers significantly higher availability for production requirements.

Q: Why is the original SPMWHT541MP5WAVGS5 marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory (851 pieces) is available for legacy support only. For new designs and ongoing production, SPMWHT541MP5WAVMS4 (Active status) or the LM281B+ series alternatives are recommended to ensure long-term supply chain continuity and component availability.
