Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WAPHSD is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Color and CCT: White, Cool 6500K
• Package / Case: 4-SMD, Flat Leads (5630)
• Mounting Type: Surface Mount
• CRI: 80
• Viewing Angle: 120°
• RoHS Compliance: RoHS Compliant or higher
• MSL Rating: 2A (4 Weeks)

Allowable Variation Parameters:

• Forward Voltage (Vf): ±0.15V tolerance acceptable for circuit design flexibility
• Test Current: 65mA nominal; maximum current rating must be ≥180mA
• Luminous Flux: ±2lm variation acceptable within specified range
• Lumens per Watt: Higher efficiency acceptable; lower efficiency requires circuit validation
• Thermal Resistance: Lower values acceptable; higher values require thermal analysis
• Product Status: Active status preferred for new supply; Not For New Designs acceptable for legacy support

The two substitute parts listed below meet these criteria through either direct parametric equivalence or functional compatibility within the LM561B/LM561C series.

Engineering Selection Recommendations

SPMWHT541MP5WAP0S5 (Direct Equivalent)

This substitute is the primary equivalent for SPMWHT541MP5WAPHSD. Both parts belong to the LM561B Plus series with identical electrical specifications: 2.95V forward voltage, 65mA test current, 34–36lm flux range, and 80 CRI. The substitute offers improved thermal performance (15°C/W vs. 16°C/W) and higher luminous efficiency (183 lm/W vs. 177 lm/W). Critically, SPMWHT541MP5WAP0S5 carries Active product status, ensuring continued supply availability and manufacturing support. Both parts maintain RoHS Compliant certification and identical MSL ratings. This part is suitable for direct replacement in existing designs without circuit modification.

SPMWHT541ML5XAPKS0 (Parametric Equivalent)

This substitute represents a parametric equivalent within the LM561C series. It maintains identical color temperature (6500K), CRI (80), viewing angle (120°), and package format (5630 4-SMD). The primary electrical difference is reduced forward voltage (2.8V vs. 2.95V), representing a 0.15V decrease. This voltage reduction results in lower power dissipation and improved thermal performance (12°C/W vs. 16°C/W). Luminous efficiency is superior (187 lm/W vs. 177 lm/W). The part carries RoHS3 Compliant certification, exceeding the main part's RoHS Compliant status. SPMWHT541ML5XAPKS0 is suitable for applications where lower forward voltage and improved thermal characteristics provide design advantages. Circuit validation is required to confirm voltage tolerance in existing designs.

Selection Criteria:

• For direct replacement with no circuit modification: SPMWHT541MP5WAP0S5
• For designs benefiting from lower forward voltage and improved thermal performance: SPMWHT541ML5XAPKS0
• Both substitutes ensure compliance with RoHS and MSL requirements
• Both maintain identical mechanical compatibility and optical specifications

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP5WAP0S5 be used as a direct drop-in replacement for SPMWHT541MP5WAPHSD?

A: Yes. Both parts are LM561B Plus series LEDs with identical forward voltage (2.95V), test current (65mA), color temperature (6500K), CRI (80), and package format (5630 4-SMD, Flat Leads). The substitute offers equivalent or superior performance across all parameters. No circuit modification is required.

Q2: What is the key difference between SPMWHT541MP5WAP0S5 and SPMWHT541ML5XAPKS0?

A: The primary difference is the LED series and forward voltage. SPMWHT541MP5WAP0S5 is LM561B Plus at 2.95V; SPMWHT541ML5XAPKS0 is LM561C at 2.8V. Both maintain 6500K color temperature, 80 CRI, and 5630 package format. The LM561C variant offers lower power dissipation and improved thermal resistance (12°C/W vs. 16°C/W).

Q3: Is the 0.15V voltage difference between SPMWHT541MP5WAPHSD (2.95V) and SPMWHT541ML5XAPKS0 (2.8V) significant?

A: The voltage difference is within typical design tolerance for LED applications. However, circuit validation is required to confirm that existing current-limiting resistor values and power supply specifications accommodate the lower voltage. The reduced voltage results in lower power dissipation, which may improve thermal performance in the application.

Q4: Why is SPMWHT541MP5WAPHSD marked as "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status in Samsung's product portfolio. While existing inventory remains available, Samsung recommends using Active-status alternatives for new designs. SPMWHT541MP5WAP0S5 and SPMWHT541ML5XAPKS0 are both Active-status parts suitable for new applications.

Q5: Are all three parts RoHS compliant?

A: Yes. SPMWHT541MP5WAPHSD and SPMWHT541MP5WAP0S5 are RoHS Compliant. SPMWHT541ML5XAPKS0 is RoHS3 Compliant, which represents a higher compliance standard. All three parts meet RoHS requirements for hazardous substance restrictions.

Q6: Do all three parts have the same package dimensions?

A: Yes. All three parts use the 5630 package format with identical dimensions: 5.00mm length × 3.00mm width, 0.80mm maximum seated height. They are mechanically interchangeable on PCBs designed for 4-SMD, Flat Leads configuration.

Q7: Which substitute offers the best thermal performance?

A: SPMWHT541ML5XAPKS0 offers the lowest thermal resistance at 12°C/W, compared to 16°C/W for the main part and 15°C/W for SPMWHT541MP5WAP0S5. This makes SPMWHT541ML5XAPKS0 preferable for applications with thermal constraints.

Q8: What is the MSL rating, and does it differ among the three parts?

A: All three parts carry MSL 2A (4 Weeks) rating, indicating they require storage in controlled humidity environments and have a 4-week floor life after moisture barrier bag opening. No difference exists among the parts in this specification.
