Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WARMS5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Color Temperature: 5000K (cool white)
• Package Type: 4-SMD, Flat Leads (5630)
• Physical Dimensions: 5.00mm x 3.00mm
• Viewing Angle: 120°
• CRI: 80
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Forward Voltage (Vf): 2.75V to 2.95V
• Test Current: 65mA (fixed operating point)
• Luminous Flux: 35lm to 37lm range
• Maximum Current: 180mA to 200mA
• Thermal Resistance: 12°C/W to 15°C/W

The substitute parts SPMWHT541ML5XAR0S5 and SPMWHT541MP5WAR0S5 meet all mandatory matching criteria and fall within allowable variation ranges for forward voltage and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MP5WAR0S5 is the primary substitute for SPMWHT541MP5WARMS5. Both components share identical electrical specifications, package geometry, and thermal characteristics. The SPMWHT541MP5WAR0S5 carries ROHS3 compliance certification and maintains 17,892 units in stock, providing superior availability compared to the original part number.

SPMWHT541ML5XAR0S5 is a secondary substitute suitable for applications where lower forward voltage operation is beneficial. This LM561C variant operates at 2.75V versus 2.95V, reducing power dissipation by approximately 6.8% at the 65mA test current. The improved thermal resistance of 12°C/W (versus 15°C/W) and higher luminous efficacy of 201 lm/W support thermal management in space-constrained designs. ROHS3 compliance is confirmed. This substitution is valid only when circuit design accommodates the lower forward voltage requirement.

Both substitute parts maintain identical color temperature, CRI, viewing angle, and physical dimensions, ensuring direct mechanical and optical compatibility in PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAR0S5 be used as a direct replacement for SPMWHT541MP5WARMS5?

A: Yes, within electrical design constraints. The 0.20V forward voltage difference (2.75V vs 2.95V) requires circuit verification. If the LED driver or current source is designed for the original 2.95V specification, the lower voltage of the LM561C variant will result in reduced power dissipation. Confirm that your current-limiting circuit maintains 65mA operation across the voltage range.

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

A: Both series operate at identical color temperature (5000K), CRI (80), and luminous flux (36lm at 65mA). The primary difference is forward voltage: LM561B Plus operates at 2.95V with 188 lm/W efficiency, while LM561C operates at 2.75V with 201 lm/W efficiency. The LM561C also supports higher maximum current (200mA vs 180mA) and exhibits superior thermal resistance (12°C/W vs 15°C/W).

Q: Are all three parts mechanically identical?

A: Yes. All three parts use the 5630 package (4-SMD, Flat Leads) with dimensions of 5.00mm x 3.00mm and maximum height of 0.80mm. PCB footprints and reflow profiles are identical.

Q: What is the inventory status of substitute parts?

A: SPMWHT541MP5WAR0S5 has 17,892 units in stock. SPMWHT541ML5XAR0S5 has 921 units in stock. The original SPMWHT541MP5WARMS5 has 1,069 units in stock.

Q: Do all parts meet RoHS compliance?

A: SPMWHT541MP5WARMS5 is RoHS Compliant. Both substitute parts carry ROHS3 Compliant certification, which represents a more recent compliance standard.

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

A: All three parts are rated MSL 2A (4 Weeks), indicating they must be stored in controlled humidity environments and used within four weeks of package opening.
