Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Direct Substitutes): Parts that maintain identical electrical specifications, optical characteristics, and physical dimensions. These parts are interchangeable at the circuit level without design modification.

Similar Substitutes (Functional Alternatives): Parts that share the same package, mounting type, and base product family but differ in specific electrical parameters such as forward voltage, luminous flux, or efficiency. These require circuit-level evaluation.

Key Parameters Determining Substitutability:

• Color and Correlated Color Temperature (CCT)
• Forward Voltage (Vf) and Maximum Current rating
• Luminous Flux output and efficiency (lm/W)
• Package type, dimensions, and thermal characteristics
• Product status and compliance certifications

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required):

Use SPMWHT541ML7XAQ0S0 or SPMWHT541ML7XAQMS0 when 5700K color temperature is required. Both parts are parametric equivalents with identical electrical and optical specifications to the SPMWHT541ML7XAQGS0. Both carry Active product status, ensuring long-term availability and supply chain stability for new designs.

For Color Temperature Variation (5000K Alternative):

SPMWHT541ML7XAR0S0 and SPMWHT541ML7XARMS0 provide identical electrical performance with 5000K CCT instead of 5700K. These parts maintain the same forward voltage, current ratings, luminous flux, and thermal characteristics. Selection depends on application color temperature requirements.

For Functional Alternative (Circuit Evaluation Required):

SPMWHT541MP7WAQ0S0 (LM561B Plus series) operates at 2.95V forward voltage with 28 lumens output and 146 lm/W efficiency. Maximum current is 180mA with 15°C/W thermal resistance. This part requires circuit-level verification due to voltage and efficiency differences but maintains 5700K color temperature and 120° viewing angle. Active product status supports new design implementation.

Compliance and Certification:

All substitute parts maintain RoHS compliance, 2A moisture sensitivity level (4 Weeks), and identical package specifications (5630, 4-SMD flat leads, 5.00 x 3.00 x 0.80 mm). All parts are suitable for tape and reel packaging.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML7XAQ0S0 directly replace SPMWHT541ML7XAQGS0 without circuit modification?

A: Yes. SPMWHT541ML7XAQ0S0 is a parametric equivalent with identical forward voltage (2.75V), test current (65mA), luminous flux (30lm), and thermal resistance (12°C/W). No circuit changes are required. The primary difference is product status: SPMWHT541ML7XAQ0S0 is Active, supporting new designs.

Q: What is the difference between SPMWHT541ML7XAQMS0 and SPMWHT541ML7XAQ0S0?

A: Both parts are parametric equivalents with identical electrical and optical specifications. The difference lies in packaging or supplier designation codes. Both are LM561C series, 5700K, with 2.75V forward voltage and 168 lm/W efficiency. Both carry Active product status.

Q: Can I use SPMWHT541ML7XAR0S0 as a substitute if my application requires 5700K?

A: No. SPMWHT541ML7XAR0S0 operates at 5000K color temperature, not 5700K. While electrical parameters are identical, the color temperature difference affects light output characteristics. Use SPMWHT541ML7XAQ0S0 or SPMWHT541ML7XAQMS0 for 5700K applications.

Q: What are the implications of using SPMWHT541MP7WAQ0S0 instead of the original part?

A: SPMWHT541MP7WAQ0S0 (LM561B Plus) differs in three key parameters: forward voltage increases to 2.95V, luminous flux decreases to 28lm, and efficiency drops to 146 lm/W. Maximum current is 180mA (vs. 200mA) and thermal resistance increases to 15°C/W (vs. 12°C/W). Circuit-level evaluation is required to confirm compatibility with existing power supply and thermal management designs.

Q: Are all substitute parts available in tape and reel packaging?

A: Yes. All listed substitute parts are supplied in tape and reel (TR) packaging format, maintaining identical handling and assembly compatibility with the original SPMWHT541ML7XAQGS0.

Q: Do substitute parts meet the same RoHS and moisture sensitivity requirements?

A: Yes. All substitute parts are RoHS compliant with 2A moisture sensitivity level (4 Weeks storage), matching the original part specifications.

Q: Which substitute part should I select for new product designs?

A: For new designs requiring 5700K color temperature, select SPMWHT541ML7XAQ0S0 or SPMWHT541ML7XAQMS0. Both are parametric equivalents with Active product status. For 5000K applications, select SPMWHT541ML7XAR0S0 or SPMWHT541ML7XARMS0. Avoid SPMWHT541ML7XAQGS0 (Not For New Designs status).
