Substitute Part Grouping Explanation

Substitution logic for SPMWHT541ML7XARGS0 is based on the following allowed parameters:

Parametric Equivalents (Full Compatibility):

• SPMWHT541ML7XAR0S0
• SPMWHT541ML7XARMS0

These parts maintain identical electrical and mechanical specifications: LM561C series, 5000K cool white, 2.75V forward voltage, 30 lm output at 65mA, 168 lm/W efficiency, 120° viewing angle, 4-SMD 5630 package, 12°C/W thermal resistance, and RoHS compliance. The only difference is packaging designation variant. Both are Active status parts, providing design continuity.

Similar Substitute (Functional Alternative):

• SPMWHT541MP7WARMS0

This part operates within the same 5000K cool white specification and 5630 package footprint. However, it represents the LM561B Plus series with modified electrical characteristics: 2.95V forward voltage (0.20V higher), 28 lm output at 65mA (2 lm lower), 146 lm/W efficiency (22 lm/W lower), and 15°C/W thermal resistance (3°C/W higher). Maximum current is 180mA versus 200mA. This part is Active status and ROHS3 compliant. Selection requires circuit voltage and thermal design verification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Path):

Select SPMWHT541ML7XAR0S0 or SPMWHT541ML7XARMS0. Both parts are electrically and mechanically identical to the main part SPMWHT541ML7XARGS0 and carry Active product status. These parts eliminate obsolescence risk while maintaining full design compatibility. Both maintain RoHS compliance and identical thermal characteristics. Selection between these two variants depends on packaging designation requirements specific to your supply chain.

For Functional Substitution (Secondary Path):

SPMWHT541MP7WARMS0 (LM561B Plus series) is suitable only when circuit design accommodates the following parameter deviations: forward voltage increase from 2.75V to 2.95V, luminous flux reduction from 30 lm to 28 lm, efficiency decrease from 168 lm/W to 146 lm/W, and thermal resistance increase from 12°C/W to 15°C/W. Maximum current rating is also reduced from 200mA to 180mA. This part is Active status and ROHS3 compliant. Use only when primary equivalents are unavailable and circuit margins support the electrical and thermal changes.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML7XAR0S0 and SPMWHT541ML7XARMS0 be used interchangeably with SPMWHT541ML7XARGS0?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (2.75V, 30 lm, 168 lm/W), mechanical dimensions (5630 package, 5.00 × 3.00 × 0.80 mm), and thermal properties (12°C/W). The difference is packaging designation only. Both are Active status parts suitable for production use.

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

A: The LM561B Plus (SPMWHT541MP7WARMS0) operates at higher forward voltage (2.95V vs. 2.75V), produces lower luminous flux (28 lm vs. 30 lm at 65mA), delivers lower efficiency (146 lm/W vs. 168 lm/W), and has higher thermal resistance (15°C/W vs. 12°C/W). Maximum current is also reduced from 200mA to 180mA. Both maintain 5000K color temperature and 90 CRI.

Q: Is SPMWHT541MP7WARMS0 a direct replacement?

A: No. While it shares the same 5000K color temperature, 5630 package footprint, and 120° viewing angle, it is a functional alternative with modified electrical and thermal characteristics. Use only when primary equivalents are unavailable and your circuit design accommodates the voltage, flux, efficiency, and thermal resistance changes.

Q: Are all substitute parts RoHS compliant?

A: Yes. SPMWHT541ML7XAR0S0 and SPMWHT541ML7XARMS0 are RoHS Compliant. SPMWHT541MP7WARMS0 is ROHS3 Compliant. All parts meet environmental compliance requirements.

Q: What is the moisture sensitivity level for these parts?

A: All parts carry MSL 2A (4 Weeks) rating. Storage and handling must follow standard moisture control procedures for this classification level.

Q: Can I use SPMWHT541MP7WARMS0 in a high-current application?

A: No. SPMWHT541MP7WARMS0 has a maximum current rating of 180mA, compared to 200mA for the LM561C series. If your application requires operation above 180mA, this part is not suitable.
