Engineering Selection Recommendations

For Direct Series Continuation: SPMWHT541MP7WAVMS0 is the primary substitute within the LM561B Plus series. This part maintains Active product status, ensuring long-term availability and supply chain stability. The 3000K CCT differs from the original 2700K specification; selection requires verification that color temperature shift is acceptable for the application. Thermal performance is improved (15°C/W vs. 20°C/W), providing better heat dissipation characteristics.

For Parametric Equivalence with Series Migration: The LM281B+ series parts (SPMWH1228FD7W2W0SJ, SPMWH1228FD7W2WKSJ, SPMWH1228FD7W2WMSJ, SPMWH1228FD7WAW0SJ, SPMWH1228FD7WAWKSJ, SPMWH1228FD7WAWMSJ) provide functional substitution with Active product status and ROHS3 compliance. These parts maintain identical 2700K CCT, package footprint, and viewing angle. Forward voltage ranges from 2.9V to 3.0V, requiring circuit verification for compatibility with existing driver designs. Test current increases to 150mA with maximum current of 200mA, indicating higher luminous output capability. Thermal resistance of 25°C/W is higher than the main part; thermal design review is necessary for applications with stringent thermal constraints.

Compliance Considerations: All substitute parts carry ROHS3 Compliant status, meeting current regulatory requirements. The main part carries RoHS Compliant status (earlier standard). All parts are classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAVMS0 be used as a direct replacement for SPMWHT541MP7WAWGS0?

A: SPMWHT541MP7WAVMS0 is mechanically and electrically compatible with identical package, footprint, and electrical ratings. The primary difference is CCT: 3000K versus 2700K. Substitution is valid only if the application accepts the warmer color temperature shift. This part offers improved thermal performance and Active product status.

Q: What is the difference between LM561B Plus and LM281B+ series substitutes?

A: Both series maintain identical package configuration (5630, 4-SMD flat leads), color (White Warm), CCT (2700K), CRI (90), and viewing angle (120°). The LM281B+ series operates at higher test current (150mA vs. 65mA) and maximum current (200mA vs. 180mA), indicating higher luminous output. Forward voltage is slightly lower (2.9V to 3.0V vs. 2.95V). Thermal resistance is higher (25°C/W vs. 20°C/W). All LM281B+ variants are Active products with ROHS3 compliance.

Q: Are there voltage compatibility concerns when substituting with LM281B+ parts?

A: LM281B+ parts operate at 2.9V to 3.0V typical forward voltage compared to 2.95V for the main part. This 0.05V to 0.10V difference is within typical LED tolerance ranges. Circuit verification is necessary to confirm driver compatibility, particularly for constant-current designs with tight voltage headroom specifications.

Q: What are the thermal implications of using LM281B+ substitutes?

A: LM281B+ parts have thermal resistance of 25°C/W compared to 20°C/W for the main part. This represents a 25% increase in thermal resistance. For applications operating at or near maximum current ratings, thermal design review is required to ensure junction temperature remains within acceptable limits.

Q: Do all substitute parts have identical physical dimensions?

A: Yes. All parts listed maintain identical 5630 package dimensions: 5.00mm length x 3.00mm width with 0.80mm maximum seated height. PCB footprints are interchangeable without layout modification.

Q: What is the inventory status of substitute parts?

A: SPMWHT541MP7WAVMS0 has 33,985 units in stock. LM281B+ variants range from 648 to 1,139 units in stock. The main part SPMWHT541MP7WAWGS0 has 934 units available. All parts are new original stock.

Q: Are there REACH compliance differences between the main part and substitutes?

A: The main part does not list REACH status. All LM281B+ substitute parts are marked as REACH Unaffected, indicating compliance with REACH regulations. SPMWHT541MP7WAVMS0 does not specify REACH status in the provided data.
