Substitute Part Grouping Explanation

Substitution of the SPMWHT541ML5XAVNS5 is determined by the following critical parameters:

Parametric Equivalents (LM561C Series): Parts maintaining identical electrical and optical characteristics within the LM561C series are classified as parametric equivalents. These parts share the same forward voltage (2.75V), test current (65mA), maximum current (200mA), luminous flux (34lm), lumens per watt (190 lm/W), color temperature (3000K), CRI (80), viewing angle (120°), and thermal resistance (12°C/W). Parametric equivalents differ only in packaging designation or regional compliance variants.

Similar Substitutes (LM561B Plus Series): Parts from the LM561B Plus series operate at higher forward voltage (2.95V) and lower maximum current (180mA) while maintaining the same test current (65mA), color temperature (3000K), CRI (80), and viewing angle (120°). These parts deliver comparable luminous flux (34lm) but with reduced lumens per watt efficiency (167-177 lm/W) and higher thermal resistance (15-16°C/W). LM561B Plus substitutes are suitable where forward voltage tolerance and thermal characteristics permit.

Key Substitution Criteria:

Color temperature: 3000K (warm white)
Package format: 5630 (4-SMD, Flat Leads)
Viewing angle: 120°
CRI: 80
Mounting type: Surface Mount
Physical dimensions: 5.00mm x 3.00mm x 0.80mm maximum height
Test current: 65mA

Engineering Selection Recommendations

Parametric Equivalent Selection (Preferred for Direct Replacement):

For applications requiring direct electrical and optical equivalence, select from the active LM561C series parts: SPMWHT541ML5XAV0S5, SPMWHT541ML5XAVKS5, SPMWHT541ML5XAVMS5, or SPMWHT541ML5XAVUS5. These parts maintain identical forward voltage (2.75V), current ratings, luminous flux (34lm), efficiency (190 lm/W), and thermal characteristics (12°C/W) as the original SPMWHT541ML5XAVNS5. All parametric equivalents are in Active product status, ensuring long-term supply availability.

SPMWHT541ML5XAVMS5 and SPMWHT541ML5XAVUS5 carry ROHS3 compliance certification, providing enhanced regulatory alignment for new designs and international markets.

Similar Substitute Selection (LM561B Plus Series):

When forward voltage tolerance exists in the circuit design, LM561B Plus series parts (SPMWHT541MP5WAV0S5, SPMWHT541MP5WAVKS5, SPMWHT541MP5WAVMS5, SPMWHT541MP5WAVNS5) provide functional substitution. These parts operate at 2.95V forward voltage (0.20V higher than LM561C) and support maximum current of 180mA (20mA lower than LM561C). Luminous flux remains at 34lm with test current of 65mA, maintaining comparable light output. Thermal resistance increases to 15°C/W, requiring thermal design verification in high-power applications.

SPMWHT541MP5WAVMS5 is the highest-inventory LM561B Plus variant (26,898 pcs) with ROHS3 compliance, offering optimal supply security and regulatory compliance.

Avoid:

SPMWHT541MP5WAVUS5 (Not For New Designs status)
SPMWHT541MP5WAVMS4 (reduced flux to 32lm, lower efficiency at 167 lm/W)

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAV0S5 directly replace SPMWHT541ML5XAVNS5 without circuit modification?

A: Yes. SPMWHT541ML5XAV0S5 is a parametric equivalent with identical electrical specifications: 2.75V forward voltage, 65mA test current, 200mA maximum current, 34lm luminous flux, 190 lm/W efficiency, and 12°C/W thermal resistance. Physical package dimensions and mounting characteristics are identical. No circuit modification is required.

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

A: The primary difference is forward voltage: LM561C operates at 2.75V while LM561B Plus operates at 2.95V. LM561B Plus also has lower maximum current rating (180mA vs. 200mA) and higher thermal resistance (15-16°C/W vs. 12°C/W). Both series maintain 3000K color temperature, 80 CRI, 120° viewing angle, and identical package dimensions. LM561B Plus is suitable only when circuit design accommodates the higher forward voltage.

Q: Why does SPMWHT541MP5WAVMS4 show lower flux (32lm) than other LM561B Plus variants?

A: SPMWHT541MP5WAVMS4 represents a different production lot or binning specification within the LM561B Plus series, resulting in 32lm flux (31-33lm range) versus 34lm (33-35lm range) for other variants. This corresponds to reduced lumens per watt efficiency (167 lm/W vs. 177 lm/W). This part should be selected only when lower flux output is acceptable for the application.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed substitute parts use the 5630 package format with 4-SMD flat leads, identical physical dimensions (5.00mm L x 3.00mm W), and maximum seated height of 0.80mm. PCB footprints and reflow soldering profiles are interchangeable across all substitutes.

Q: What is the significance of ROHS3 compliance versus RoHS compliance?

A: ROHS3 represents compliance with the latest Restriction of Hazardous Substances directive, incorporating additional restricted substances and stricter testing requirements compared to standard RoHS compliance. Parts with ROHS3 certification (SPMWHT541ML5XAVMS5, SPMWHT541ML5XAVUS5, SPMWHT541MP5WAVMS4, SPMWHT541MP5WAVMS5) are recommended for applications requiring enhanced regulatory alignment or export to markets with stringent environmental standards.

Q: Which substitute offers the best supply availability?

A: SPMWHT541ML5XAVMS5 (LM561C, 10,671 pcs inventory) and SPMWHT541MP5WAVMS5 (LM561B Plus, 26,898 pcs inventory) represent the highest inventory levels. SPMWHT541MP5WAVMS5 provides maximum supply security for LM561B Plus applications.

Q: Can I use LM561B Plus parts in existing designs without thermal analysis?

A: No. LM561B Plus parts have higher thermal resistance (15-16°C/W vs. 12°C/W for LM561C) and higher forward voltage (2.95V vs. 2.75V). Thermal design verification is required to confirm junction temperature remains within acceptable limits. Forward voltage increase may require current-limiting resistor adjustment in constant-current driver circuits.

Q: What is the Moisture Sensitivity Level (MSL) 2A specification?

A: MSL 2A indicates the component can be stored in dry conditions for up to 4 weeks before soldering. After this period, the component must be baked at specified temperature and humidity conditions before use to prevent moisture-induced solder joint failures. All listed parts share MSL 2A classification.
