Key Parameters

Substitute Part Grouping Explanation

Substitute parts for SPMWHT541MP5WAQMS5 are qualified based on the following criteria:

Mechanical Compatibility: All substitute parts share identical package type (4-SMD, Flat Leads), supplier device package (5630), and physical dimensions (5.00 × 3.00 mm footprint, 0.80 mm seated height). This ensures direct PCB layout compatibility without redesign.

Electrical Compatibility: Substitute parts operate within the same forward voltage range (2.75–2.95V typical) and support the same test current (65 mA) and maximum current ratings (180–200 mA). Flux output at 25°C and 65 mA test current remains within the 35–37 lm specification range across all substitutes.

Optical Characteristics: All substitutes maintain 120° viewing angle and CRI of 80, preserving optical performance in target applications.

Key Differentiators: Substitutes vary in color temperature (5000K vs. 5700K) and series designation (LM561B Plus vs. LM561C), which determine suitability based on application requirements. Thermal resistance and compliance certifications also differ between specific part numbers.

Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MP5WAR0S5 (LM561B Plus, 5000K): Direct substitute for applications requiring 5000K color temperature instead of 5700K. Maintains identical forward voltage (2.95V), test current (65 mA), and thermal characteristics (15°C/W). ROHS3 Compliant certification. Highest inventory availability (17,892 pcs) supports production volume requirements.

SPMWHT541MP5WARMS5 (LM561B Plus, 5000K): Functionally equivalent to SPMWHT541MP5WAR0S5 with identical electrical and thermal specifications. RoHS Compliant (non-ROHS3). Lower inventory (1,069 pcs) suitable for limited production runs or replacement stock.

SPMWHT541ML5XAR0S5 (LM561C, 5000K): Alternative for applications where improved thermal performance is required. Lower forward voltage (2.75V typical) and higher maximum current rating (200 mA vs. 180 mA). Superior lumens/watt efficiency (201 lm/W vs. 188 lm/W). Lower thermal resistance (12°C/W vs. 15°C/W). ROHS3 Compliant. Suitable for high-brightness or thermally constrained designs. Moderate inventory (921 pcs).

Color Temperature Selection: Choose 5700K (SPMWHT541MP5WAQMS5) for cooler, daylight-balanced applications. Select 5000K variants (SPMWHT541MP5WAR0S5, SPMWHT541MP5WARMS5, SPMWHT541ML5XAR0S5) for neutral white applications or when existing designs specify 5000K.

Compliance Consideration: ROHS3 Compliant parts (SPMWHT541MP5WAR0S5, SPMWHT541ML5XAR0S5) meet current regulatory requirements for new designs. RoHS Compliant parts (SPMWHT541MP5WAQMS5, SPMWHT541MP5WARMS5) remain suitable for existing product lines.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAR0S5 replace SPMWHT541MP5WAQMS5 directly on the PCB?

A: Yes. Both parts share identical 5630 package dimensions (5.00 × 3.00 × 0.80 mm), 4-SMD flat lead configuration, and footprint. No PCB layout modification is required. The primary difference is color temperature (5000K vs. 5700K).

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

A: LM561B Plus operates at 2.95V typical forward voltage with 180 mA maximum current and 15°C/W thermal resistance. LM561C operates at 2.75V typical forward voltage with 200 mA maximum current and 12°C/W thermal resistance. LM561C provides better thermal performance and higher current capability. Both deliver equivalent flux output (36 lm) at 65 mA test current.

Q: Which substitute offers the best thermal performance?

A: SPMWHT541ML5XAR0S5 (LM561C series) provides the lowest thermal resistance at 12°C/W compared to 15°C/W for LM561B Plus variants. This part is recommended for applications with thermal constraints or high ambient temperature operation.

Q: Are all substitutes compatible with the same driver circuit?

A: All substitutes operate within compatible voltage and current ranges at the 65 mA test point. However, SPMWHT541ML5XAR0S5 has lower forward voltage (2.75V vs. 2.95V), which may require driver circuit verification for applications operating near voltage limits. Maximum current ratings differ (180 mA vs. 200 mA), so verify driver current capability.

Q: What is the inventory status for each substitute?

A: SPMWHT541MP5WAR0S5 has highest availability (17,892 pcs). SPMWHT541MP5WARMS5 has 1,069 pcs. SPMWHT541ML5XAR0S5 has 921 pcs. Original part SPMWHT541MP5WAQMS5 has 1,012 pcs in stock.

Q: Do all parts meet current RoHS requirements?

A: SPMWHT541MP5WAR0S5 and SPMWHT541ML5XAR0S5 are ROHS3 Compliant. SPMWHT541MP5WAQMS5 and SPMWHT541MP5WARMS5 are RoHS Compliant. For new designs, ROHS3 Compliant parts are recommended.

Q: Can I mix different substitute parts in the same assembly?

A: Yes, all substitutes are mechanically and electrically compatible. However, mixing 5700K (original part) with 5000K variants (substitutes) in the same application may result in visible color temperature variation. Maintain consistent color temperature selection across an assembly for uniform optical appearance.
