Engineering Selection Recommendations

Parametric Equivalents (Recommended for Direct Substitution)

The parts SPMWHT541ML5XAW0S0, SPMWHT541ML5XAWKS0, SPMWHT541ML5XAWMS0, and SPMWHT541ML5XAWSS0 are parametric equivalents within the LM561C series and are classified as Active products. These parts maintain compatibility across forward voltage (2.75V to 2.8V), flux output (32lm), CRI (80), package form, and thermal characteristics. All carry RoHS certification (either RoHS or ROHS3 compliant). Selection among these equivalents may be based on inventory availability, thermal resistance optimization (12°C/W vs. 14°C/W), and maximum current rating requirements (180mA vs. 200mA).

Similar Alternative (LM561B Plus Series)

The part SPMWHT541MP5WAWMS4 represents a different LED series (LM561B Plus) with compatible electrical and optical parameters: 2700K CCT, 80 CRI, and 120° viewing angle in the same 5630 package. This part is Active and RoHS Compliant. The forward voltage is slightly higher at 2.95V, flux is marginally lower at 31lm, lumens per watt is lower at 162 lm/W, and dimensions differ (5.60mm length vs. 5.00mm). This alternative is suitable where the LM561C series is unavailable and the electrical parameter variations are acceptable to circuit design.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAWMS0 replace SPMWHT541ML5XAWGS0 directly in production?

A: Yes. Both parts are warm white 2700K LEDs in 4-SMD 5630 packages with 80 CRI and 120° viewing angle. SPMWHT541ML5XAWMS0 is Active (vs. Not For New Designs), features identical flux output (32lm at 25°C), and operates within the same test current (65mA). Forward voltage differs by 0.05V (2.8V vs. 2.75V), which is within typical design tolerances. Maximum current is 180mA (vs. 200mA) and thermal resistance is 12°C/W (vs. 14°C/W), both favorable. RoHS/ROHS3 compliance is maintained.

Q: What are the key differences between LM561C and LM561B Plus substitutes?

A: The primary differences are forward voltage (2.75V–2.8V for LM561C vs. 2.95V for LM561B Plus), luminous efficiency (176–180 lm/W for LM561C vs. 162 lm/W for LM561B Plus), and physical length (5.00mm for LM561C vs. 5.60mm for LM561B Plus). All maintain 2700K CCT, 80 CRI, and 120° viewing angle. LM561B Plus substitution is suitable only when LM561C inventory is exhausted and circuit voltage headroom accommodates the 0.20V higher forward voltage.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry either RoHS or ROHS3 certification. SPMWHT541ML5XAWMS0 and SPMWHT541ML5XAWSS0 specify ROHS3 Compliant status. Designs requiring REACH compliance should note that SPMWHT541ML5XAWSS0 explicitly identifies REACH Unaffected status.

Q: How do thermal resistance differences affect selection?

A: The main part (SPMWHT541ML5XAWGS0) has thermal resistance of 14°C/W. Most active equivalents (SPMWHT541ML5XAW0S0, SPMWHT541ML5XAWKS0, SPMWHT541ML5XAWMS0, SPMWHT541ML5XAWSS0) offer improved thermal performance at 12°C/W. Lower thermal resistance improves heat dissipation and extends component lifespan in high-temperature environments. Selection should account for circuit board thermal design and ambient operating temperature limits.

Q: Can SPMWHT541MP5WAWMS4 be used in space-constrained assemblies?

A: No. SPMWHT541MP5WAWMS4 (LM561B Plus) is 5.60mm in length, compared to 5.00mm for LM561C equivalents. This 0.60mm difference may conflict with tight PCB routing or component placement constraints. Use LM561B Plus only where physical space accommodation is confirmed.

Q: What maximum current ratings should circuit design account for?

A: The original part (SPMWHT541ML5XAWGS0) specifies 200mA maximum current. Most active equivalents (SPMWHT541ML5XAW0S0, SPMWHT541ML5XAWKS0, SPMWHT541ML5XAWMS0) reduce maximum current to 180mA. SPMWHT541ML5XAWSS0 maintains the 200mA maximum. Current limiting circuits must be verified to ensure they do not exceed substitute part ratings.
