Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MP5WAR0S5 (LM561B Plus, 5000K)

This substitute maintains identical electrical and thermal characteristics to the main part while shifting color temperature from 5700K to 5000K. Both parts are LM561B Plus series with 2.95V forward voltage, 180mA maximum current, and 15°C/W thermal resistance. ROHS3 compliance provides enhanced environmental standards. Selection is appropriate when application specifications permit 5000K color temperature operation within the cool white range.

SPMWHT541MP5WARMS5 (LM561B Plus, 5000K)

This substitute is electrically and thermally identical to SPMWHT541MP5WAR0S5, offering the same LM561B Plus series performance at 5000K. RoHS Compliant status matches the main part. Inventory availability (1069 Pcs) provides alternative sourcing. Selection criteria are identical to SPMWHT541MP5WAR0S5.

SPMWHT541ML5XAR0S5 (LM561C, 5000K)

This substitute represents a different LED series (LM561C) with modified electrical characteristics. Forward voltage is reduced to 2.75V (0.20V lower than main part), and maximum current rating increases to 200mA. Luminous efficacy improves to 201 lm/W compared to 188 lm/W. Thermal resistance improves to 12°C/W. ROHS3 compliance applies. Selection requires verification that the lower forward voltage and higher efficacy are compatible with circuit design and thermal management strategy. This part is suitable when improved thermal performance or higher current capability is required.

All substitute parts maintain identical mechanical compatibility, package dimensions, and mounting characteristics. Product status is Active for all options, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAR0S5 be used as a direct replacement for SPMWHT541MP5WAQ0S5?

A: Yes, within application constraints. Both parts are LM561B Plus series with identical forward voltage (2.95V), maximum current (180mA), thermal resistance (15°C/W), and package dimensions. The primary difference is color temperature: 5000K versus 5700K. Direct substitution is valid when the application design permits operation at 5000K color temperature within the cool white range.

Q: What is the significance of the CCT difference between 5700K and 5000K?

A: Correlated Color Temperature (CCT) defines the perceived color of white light. 5700K is cooler (more blue-shifted) than 5000K (more neutral white). Both fall within the cool white category. Selection depends on application requirements for color appearance. Optical performance (luminous flux, efficacy) remains consistent across this range for the LM561B Plus series.

Q: Why does SPMWHT541ML5XAR0S5 have lower forward voltage (2.75V vs. 2.95V)?

A: SPMWHT541ML5XAR0S5 belongs to the LM561C series, which has different semiconductor characteristics than LM561B Plus. The 0.20V reduction in forward voltage is a material property of the LM561C die. This affects circuit design considerations, particularly in series-connected LED strings or current-limiting resistor calculations. The lower voltage also contributes to improved thermal resistance (12°C/W vs. 15°C/W).

Q: Is SPMWHT541ML5XAR0S5 a suitable substitute if thermal management is critical?

A: SPMWHT541ML5XAR0S5 offers superior thermal performance with 12°C/W thermal resistance compared to 15°C/W for LM561B Plus parts. However, substitution requires verification that the lower forward voltage (2.75V) is compatible with the circuit design. The higher luminous efficacy (201 lm/W vs. 188 lm/W) also generates less heat at equivalent light output, providing additional thermal benefit.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts meet RoHS requirements. SPMWHT541MP5WAQ0S5 and SPMWHT541MP5WARMS5 carry RoHS Compliant status. SPMWHT541MP5WAR0S5 and SPMWHT541ML5XAR0S5 carry ROHS3 Compliant status, which represents enhanced environmental compliance standards.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Mechanical and package compatibility is identical across all parts (5630 form factor, 4-SMD flat leads, 5.00mm × 3.00mm dimensions, 0.80mm height). Electrical interchangeability depends on forward voltage tolerance in the circuit design. Parts with 2.95V forward voltage (LM561B Plus) are directly interchangeable. SPMWHT541ML5XAR0S5 with 2.75V forward voltage requires circuit verification before substitution.

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

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 according to IPC standards before use. All substitute parts carry identical MSL 2A (4 Weeks) rating, requiring consistent handling procedures.

Q: How do the luminous efficacy values compare?

A: LM561B Plus parts (main and first two substitutes) deliver 188 lm/W at 65mA test current. SPMWHT541ML5XAR0S5 (LM561C) delivers 201 lm/W, representing 6.9% higher efficacy. Higher efficacy means more light output per watt of power consumed, reducing thermal load and improving overall system efficiency.

Q: Are there inventory considerations for substitute selection?

A: Inventory levels vary: SPMWHT541MP5WAQ0S5 (1014 Pcs), SPMWHT541MP5WAR0S5 (17892 Pcs), SPMWHT541MP5WARMS5 (1069 Pcs), SPMWHT541ML5XAR0S5 (921 Pcs). SPMWHT541MP5WAR0S5 offers significantly higher availability. Inventory status should be verified at time of procurement, as quantities are subject to change.
