Substitute Part Grouping Explanation

Substitution of the SPMWHT541ML5XARGS6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (LM561C)
• Color specification (White, Cool)
• Color temperature (5000K)
• Flux output range at 25°C and 65mA test current (37–39 lumens)
• Forward voltage (2.75V nominal)
• Maximum current rating (200mA)
• Viewing angle (120°)
• Color Rendering Index (80)
• Package format (4-SMD, Flat Leads)
• Physical dimensions (5.00mm × 3.00mm)
• Maximum seated height (0.80mm)
• Thermal resistance (12°C/W)
• Moisture sensitivity classification (2A, 4 Weeks)

The substitute part SPMWHT541ML5XAR0S6 meets all mandatory parameters and is therefore classified as a parametric equivalent. Both parts share the same base product number (SPMWHT541) and are manufactured by Samsung Semiconductor, Inc. The substitute maintains identical electrical performance, optical characteristics, and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHT541ML5XARGS6 and SPMWHT541ML5XAR0S6 are Active products manufactured by Samsung Semiconductor, Inc., and are suitable for direct substitution in applications requiring LM561C cool white LEDs at 5000K color temperature.

Selection Criteria Based on Provided Data:

The substitute part SPMWHT541ML5XAR0S6 offers the following advantages:

• Higher current inventory availability (1054 units versus 918 units)
• Explicit RoHS3 compliance certification
• Identical electrical, optical, and mechanical specifications
• Equivalent thermal and moisture sensitivity characteristics

The main part SPMWHT541ML5XARGS6 remains a valid selection where existing supply agreements, inventory management, or design documentation specify this exact part number.

Both parts are classified as parametric equivalents and may be used interchangeably in circuit designs, PCB layouts, and manufacturing processes without modification to electrical schematics, thermal management strategies, or mechanical assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAR0S6 be used as a direct replacement for SPMWHT541ML5XARGS6?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (2.75V forward voltage, 65mA test current, 38 lumens at 25°C), optical characteristics (5000K, 80 CRI, 120° viewing angle), and mechanical properties (5630 package, 5.00mm × 3.00mm, 0.80mm height). No circuit modifications are required.

Q: Are there differences in thermal performance between these parts?

A: No. Both parts have identical thermal resistance of 12°C/W and are packaged in the same 4-SMD, flat leads configuration. Thermal management strategies remain unchanged.

Q: What is the significance of the RoHS3 compliance notation on the substitute part?

A: The substitute part SPMWHT541ML5XAR0S6 explicitly declares RoHS3 compliance. This certification indicates conformance to Restriction of Hazardous Substances regulations. The main part does not include this specification in the provided data; however, both parts are manufactured by Samsung Semiconductor, Inc., and share identical material composition.

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both parts are classified as MSL 2A with a 4-week floor life. Identical moisture control, storage, and handling procedures apply to both components.

Q: Can these parts be mixed within the same production batch?

A: Yes. The parts are parametric equivalents with identical specifications. Mixed usage within a single production batch does not introduce performance variation or compatibility issues.

Q: What is the difference in lumens per watt between the two parts?

A: The main part specifies 213 lm/W while the substitute specifies 212 lm/W. This 1 lm/W difference falls within normal manufacturing tolerance for LED components and does not affect functional performance or system-level efficiency calculations.

Q: Are the packaging formats identical?

A: Yes. Both parts are supplied in Tape & Reel (TR) format with identical spool specifications, component spacing, and handling requirements.
