The lower forward voltage (2.75V) and improved thermal characteristics (12°C/W) do not compromise circuit compatibility when operating at the 65mA test current. The identical 34 lumen output and 5630 package dimensions ensure mechanical compatibility.
Q: What is the primary difference between LM561B Plus and LM561C variants? A: Forward voltage differs at 2.95V (LM561B Plus) versus 2.75V (LM561C), with the LM561C offering higher maximum current (200mA vs. 180mA), improved efficiency (190 lm/W vs. 177 lm/W), and lower thermal resistance (12°C/W vs. 15°C/W). Both maintain identical light output, color temperature, CRI, and package specifications.
Q: Are all listed substitutes suitable for new designs? A: No. SPMWHT541MP5WAVRS5 and SPMWHT541MP5WAVUS5 are designated Not For New Designs. For new designs, select from active-status parts: SPMWHT541MP5WAVSS5, SPMWHT541MP5WAV0S5, SPMWHT541MP5WAVNS5, SPMWHT541MP5WAVKS5, SPMWHT541MP5WAVMS5, SPMWHT541ML5XAV0S5, SPMWHT541ML5XAVKS5, or SPMWHT541ML5XAVMS5.
Q: Does packaging differ among substitute parts? A: No. All listed parts use identical 4-SMD flat lead configuration in 5630 package format (5.00mm × 3.00mm), mounted as tape and reel, with maximum seated height of 0.031" (0.80mm) and MSL 2A rating.
Q: Which substitute offers best inventory availability? A: SPMWHT541MP5WAVMS5 provides the highest stock level at 26,898 pieces, with ROHS3 compliance and active product status.
Q: Are forward voltage differences significant for circuit design? A: The 0.2V difference between LM561B Plus (2.95V) and LM561C (2.75V) requires evaluation within specific circuit topology. Current-limiting resistor values or LED driver specifications may require adjustment. Both voltage levels operate within standard LED driver input ranges.
