Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541ML5XAVKS5 are classified into two groups based on electrical and thermal compatibility:

Group 1: Direct LM561C Series Equivalents These parts maintain identical electrical specifications and thermal characteristics. Substitution is based on matching the following critical parameters: 3000K color temperature, 2.75V forward voltage, 65mA test current, 34 lm output, 190 lm/W efficiency, 12°C/W thermal resistance, and 5630 package dimensions. Parts in this group differ only in packaging suffix codes (KS5, 0S5, MS5) which indicate different tape reel configurations or regional variants.

Group 2: LM561B Plus Series Alternatives These parts share the same 3000K color temperature, 65mA test current, 34 lm output, 120° viewing angle, and 5630 package footprint. However, they operate at a higher forward voltage (2.95V vs. 2.75V), deliver lower efficiency (177 lm/W vs. 190 lm/W), have a higher maximum current rating (180mA vs. 200mA), and exhibit higher thermal resistance (15°C/W vs. 12°C/W). These differences require circuit design verification for voltage drop and thermal management compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Group 1 - LM561C Series): SPMWHT541ML5XAV0S5 and SPMWHT541ML5XAVMS5 are direct electrical and thermal equivalents to SPMWHT541ML5XAVKS5. All three parts maintain identical forward voltage, test current, luminous flux, efficiency, and thermal resistance. Selection between these three parts depends on packaging suffix requirements and regional compliance certifications. SPMWHT541ML5XAVMS5 carries ROHS3 Compliant certification, while SPMWHT541ML5XAVKS5 and SPMWHT541ML5XAV0S5 carry standard RoHS Compliant status. All three are Active products suitable for new designs.

For Alternative Substitution (Group 2 - LM561B Plus Series): SPMWHT541MP5WAVMS5 is an Active product with ROHS3 Compliant certification. SPMWHT541MP5WAVUS5 carries "Not For New Designs" status and should not be selected for new circuit implementations. Both LM561B Plus parts operate at 2.95V forward voltage (200mV higher than LM561C), reducing efficiency to 177 lm/W and limiting maximum current to 180mA. These parts are suitable only when circuit design accommodates the higher voltage drop and thermal resistance increase (15°C/W vs. 12°C/W).

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAV0S5 replace SPMWHT541ML5XAVKS5 without circuit modification? A: Yes. Both parts are LM561C series with identical electrical specifications: 2.75V forward voltage, 65mA test current, 34 lm output, and 12°C/W thermal resistance. The suffix difference (KS5 vs. 0S5) indicates packaging or regional variant only. No circuit changes are required.

Q: What is the difference between LM561C and LM561B Plus series? A: The LM561B Plus series operates at 2.95V forward voltage compared to 2.75V for LM561C, resulting in 200mV higher voltage drop per LED. LM561B Plus delivers 177 lm/W efficiency versus 190 lm/W for LM561C. Thermal resistance is 15°C/W for LM561B Plus versus 12°C/W for LM561C. Maximum current is limited to 180mA for LM561B Plus versus 200mA for LM561C.

Q: Can I use SPMWHT541MP5WAVUS5 in a new design? A: No. SPMWHT541MP5WAVUS5 carries "Not For New Designs" product status. Use SPMWHT541MP5WAVMS5 instead, which is Active and ROHS3 Compliant.

Q: Are all substitute parts in the same 5630 package? A: Yes. All listed parts use the 5630 supplier device package with identical dimensions (5.00mm × 3.00mm) and maximum seated height (0.80mm). All are 4-SMD with flat leads and surface mount compatible.

Q: What is the MSL rating for these parts? A: All parts carry MSL 2A rating with 4-week floor life. Moisture sensitivity handling procedures are identical across all substitute parts.

Q: If I switch from LM561C to LM561B Plus, what circuit parameters change? A: Forward voltage increases from 2.75V to 2.95V per LED. Efficiency decreases from 190 lm/W to 177 lm/W. Thermal resistance increases from 12°C/W to 15°C/W. Maximum current rating decreases from 200mA to 180mA. Current-limiting resistor values and thermal management design must be recalculated.
