Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP5WAQGS5 are classified into two categories based on substitution criteria:

Direct Substitutes (Same Series - LM561B Plus): The part SPMWHT541MP5WAQ0S5 is a direct substitute within the same LM561B Plus series. This part maintains identical electrical and mechanical specifications including color temperature (5700K), forward voltage (2.95V), test current (65mA), maximum current (180mA), CRI (80), viewing angle (120°), and package format (4-SMD, Flat Leads, 5630). The primary difference is product status (Active vs. Not For New Designs) and thermal resistance (15°C/W vs. 20°C/W). This part is suitable for direct replacement in existing designs.

Parametric Equivalents (Different Series - LM281B+): The parts SPMWH1228FD5W2Q0SJ, SPMWH1228FD5W2QKSJ, and SPMWH1228FD5W2QMSJ are parametric equivalents from the LM281B+ series. These parts share critical parameters with the main part: color temperature (5700K), CRI (80), viewing angle (120°), package format (4-SMD, Flat Leads, 5630), and physical dimensions (0.197" L x 0.118" W, 0.031" max height). However, they differ in forward voltage (2.9V vs. 2.95V), test current (150mA vs. 65mA), and maximum current (200mA vs. 180mA). These parts are suitable for applications where the higher current rating and different thermal characteristics (25°C/W) are acceptable.

Key Parameters Determining Substitution:

• Color temperature (5700K)
• Color Rendering Index (80)
• Package format (4-SMD, Flat Leads, 5630)
• Physical dimensions (0.197" L x 0.118" W, 0.031" max height)
• Viewing angle (120°)
• Surface mount mounting type

Engineering Selection Recommendations

For Direct Replacement (Same Series): SPMWHT541MP5WAQ0S5 is the recommended direct substitute for SPMWHT541MP5WAQGS5. Both parts are from the LM561B Plus series and share identical electrical and mechanical specifications. SPMWHT541MP5WAQ0S5 has Active product status, ensuring continued availability and support. The improved thermal resistance (15°C/W vs. 20°C/W) provides enhanced thermal performance. Both parts are RoHS Compliant and carry identical MSL ratings (2A, 4 Weeks).

For Parametric Equivalents (Different Series): SPMWH1228FD5W2Q0SJ, SPMWH1228FD5W2QKSJ, and SPMWH1228FD5W2QMSJ from the LM281B+ series are suitable alternatives when the higher current rating (150mA test current, 200mA maximum) and different thermal characteristics (25°C/W) are compatible with the application. All three parts maintain Active product status and are ROHS3 Compliant with REACH Unaffected status. These parts are interchangeable with each other within the LM281B+ series.

Compliance Considerations: All substitute parts maintain RoHS compliance. The LM281B+ series parts carry ROHS3 Compliant status with REACH Unaffected designation, providing enhanced regulatory assurance for new applications.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAQ0S5 be used as a direct replacement for SPMWHT541MP5WAQGS5? A: Yes. SPMWHT541MP5WAQ0S5 is a direct substitute within the same LM561B Plus series with identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current) and mechanical specifications (5630 package, 4-SMD flat leads, 0.197" x 0.118" dimensions). The primary advantage is Active product status versus Not For New Designs status of the original part.

Q: What are the differences between the LM561B Plus and LM281B+ series parts? A: The LM281B+ series parts (SPMWH1228FD5W2Q0SJ, SPMWH1228FD5W2QKSJ, SPMWH1228FD5W2QMSJ) operate at higher test current (150mA vs. 65mA) and maximum current (200mA vs. 180mA) with slightly lower forward voltage (2.9V vs. 2.95V). Thermal resistance is higher (25°C/W vs. 20°C/W). Color temperature, CRI, viewing angle, and package format remain identical.

Q: Are the three LM281B+ parts interchangeable with each other? A: Yes. SPMWH1228FD5W2Q0SJ, SPMWH1228FD5W2QKSJ, and SPMWH1228FD5W2QMSJ share identical electrical and mechanical specifications. They differ only in packaging or supplier designation codes. All three are suitable for the same applications.

Q: What is the impact of different thermal resistance values? A: Thermal resistance (°C/W) affects heat dissipation characteristics. SPMWHT541MP5WAQ0S5 has lower thermal resistance (15°C/W), providing better heat dissipation than the original part (20°C/W). The LM281B+ series parts have higher thermal resistance (25°C/W), which may require consideration in thermally constrained applications.

Q: Are all substitute parts RoHS compliant? A: Yes. SPMWHT541MP5WAQ0S5 is RoHS Compliant. The LM281B+ series parts are ROHS3 Compliant with REACH Unaffected status, providing enhanced regulatory compliance for applications requiring stricter environmental standards.

Q: Can the LM281B+ series parts be used in applications designed for the LM561B Plus? A: The LM281B+ series parts are parametric equivalents suitable for applications where the higher current rating (150mA test, 200mA maximum) and different thermal characteristics (25°C/W) are acceptable. Circuit design must accommodate the different forward voltage (2.9V vs. 2.95V) and current specifications.

Q: What is the moisture sensitivity level for these parts? A: SPMWHT541MP5WAQGS5 and SPMWHT541MP5WAQ0S5 have MSL rating of 2A (4 Weeks). The LM281B+ series parts do not specify MSL in the provided data. Standard handling procedures for MSL 2A components apply to the LM561B Plus parts.

Q: Are there inventory considerations for part selection? A: Current inventory levels are: SPMWHT541MP5WAQGS5 (738 pcs), SPMWHT541MP5WAQ0S5 (1014 pcs), SPMWH1228FD5W2Q0SJ (882 pcs), SPMWH1228FD5W2QKSJ (1048 pcs), and SPMWH1228FD5W2QMSJ (666 pcs). Inventory status should be confirmed at time of procurement.
