Engineering Selection Recommendations

For 5700K Cool White Requirement (Exact CCT Match):

SPMWHT541MP5WAQ0S5 is the primary recommended substitute. This LM561B Plus variant maintains identical series lineage, forward voltage (2.95V), and color temperature (5700K) while offering Active product status and improved thermal resistance (15°C/W). Electrical and optical performance are equivalent to the main part.

SPMWHT541ML5XAQ0S0 and SPMWHT541ML5XAQKS0 provide LM561C alternatives with 5700K CCT. These parts deliver superior thermal performance (12°C/W) and higher luminous efficiency (192–196 lm/W). The LM561C series represents a newer generation with enhanced performance characteristics. SPMWHT541ML5XAQKS0 offers the highest inventory availability (155,477 pcs) and ROHS3 compliance, with Cut Tape packaging suitable for high-volume applications.

For 5000K Cool White Requirement (Alternative CCT):

SPMWHT541ML5XAR0S0 and SPMWHT541ML5XARKS0 are LM561C variants with 5000K CCT. These parts maintain all mechanical and electrical compatibility while shifting color temperature 700K cooler. Selection depends on CCT tolerance in the application circuit.

Compliance and Supply Chain Considerations:

All substitute parts are RoHS or ROHS3 compliant. The main part (SPMWHT541MP5WAQMSD) carries Not For New Designs status, making transition to Active alternatives necessary for ongoing production. SPMWHT541ML5XAQKS0 provides the most robust supply position with 155,477 pcs inventory and ROHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAQ0S5 directly replace SPMWHT541MP5WAQMSD in existing designs?

A: Yes. Both parts are LM561B Plus series with identical 5700K CCT, 2.95V forward voltage, 65mA test current, and 4-SMD 5630 package. The substitute offers improved thermal resistance (15°C/W vs. 16°C/W) and Active product status. No circuit modifications are required.

Q: What is the difference between LM561B Plus and LM561C series?

A: LM561C is a newer generation with improved thermal characteristics (12°C/W vs. 16°C/W) and higher luminous efficiency (192–196 lm/W vs. 183 lm/W). Forward voltage ranges from 2.75V–2.8V compared to 2.95V in LM561B Plus. Both series maintain identical mechanical footprint and 120° viewing angle.

Q: Are the 5700K and 5000K variants interchangeable?

A: No. Color temperature is a primary specification parameter. 5700K (cool white) and 5000K (cool white, slightly warmer) are distinct products. Selection depends on application CCT requirements. Substitution between these variants is only valid if the application circuit tolerates 700K color temperature variation.

Q: What is the significance of Tape & Reel versus Cut Tape packaging?

A: Tape & Reel (TR) packaging is standard for automated pick-and-place assembly in moderate to high-volume production. Cut Tape (CT) packaging is suitable for manual assembly or lower-volume applications. Both formats contain identical components; packaging selection depends on assembly process requirements. SPMWHT541ML5XAQKS0 in Cut Tape format offers the same electrical and optical performance as Tape & Reel variants.

Q: Does forward voltage variation (2.75V, 2.8V, 2.95V) affect circuit compatibility?

A: Forward voltage differences within the 2.75V–2.95V range are within typical LED operating tolerance. Circuit designs using current-limiting resistors or constant-current drivers accommodate this variation. For voltage-regulated applications, verify that the power supply headroom accommodates the lower Vf of LM561C variants (2.75V–2.8V) to ensure adequate current delivery.

Q: Why does SPMWHT541ML5XAQKS0 have significantly higher inventory (155,477 pcs)?

A: SPMWHT541ML5XAQKS0 is an Active product in the newer LM561C series with ROHS3 compliance, indicating current production and market demand. Higher inventory reflects its status as a current-generation component suitable for new designs. The main part (SPMWHT541MP5WAQMSD) is Not For New Designs, explaining lower stock levels.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry either RoHS or ROHS3 compliance certification. ROHS3 represents the current regulatory standard. Both certifications meet environmental and hazardous substance restrictions for electronic components.
