Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541ML5XATKS6 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Series designation (LM561C)
• Color specification (White, Neutral)
• CCT rating (4000K)
• Flux output at test conditions (37lm ±1lm range)
• Forward voltage (2.75V typical)
• Test current (65mA)
• Maximum current rating (200mA)
• Luminous efficacy (207 lm/W)
• CRI value (80)

Mechanical Equivalence Criteria:

• Package type (4-SMD, Flat Leads)
• Supplier device package (5630)
• Physical dimensions (5.00mm × 3.00mm)
• Maximum seated height (0.80mm)
• Viewing angle (120°)
• Thermal resistance (12°C/W)

Compliance & Environmental Criteria:

• RoHS compliance status
• Moisture sensitivity level (2A, 4 Weeks)
• ECCN classification (EAR99)
• HTSUS code (8541.41.0000)

Substitute parts must match all electrical, mechanical, and compliance parameters to ensure direct interchangeability in circuit design and PCB assembly without modification.

Parameter Comparison

Engineering Selection Recommendations

Both SPMWHT541ML5XATKS6 and SPMWHT541ML5XATMS6 are Active product status components manufactured by Samsung Semiconductor, Inc., within the LM561C series. All electrical parameters, mechanical dimensions, and thermal characteristics are identical between the two part numbers.

The primary distinction is the RoHS compliance designation: SPMWHT541ML5XATKS6 carries RoHS Compliant status, while SPMWHT541ML5XATMS6 carries ROHS3 Compliant status. Both designations indicate compliance with Restriction of Hazardous Substances regulations and are acceptable for applications requiring RoHS certification.

Selection between these two part numbers should be based on specific supply chain requirements, inventory availability, and compliance documentation requirements for your application. Both parts are electrically and mechanically interchangeable with no circuit or assembly modifications required.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XATMS6 be used as a direct replacement for SPMWHT541ML5XATKS6?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including forward voltage, test current, flux output, color temperature, viewing angle, package dimensions, and thermal characteristics. No circuit modifications or PCB redesign is required.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant designations?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents a more recent version of the RoHS directive. Both are acceptable for applications requiring RoHS certification. Consult your compliance documentation requirements to determine which designation is appropriate for your specific application.

Q: Are the 5630 package dimensions identical between both part numbers?

A: Yes. Both SPMWHT541ML5XATKS6 and SPMWHT541ML5XATMS6 use the 5630 supplier device package with identical physical dimensions of 5.00mm × 3.00mm and maximum seated height of 0.80mm. PCB footprints and assembly processes are identical.

Q: What is the maximum operating current for these LEDs?

A: The maximum current rating is 200mA for both part numbers. The test current is 65mA, at which the flux output is specified as 37lm (36lm–38lm range).

Q: Are these parts suitable for high-temperature applications?

A: The thermal resistance of the package is 12°C/W for both parts. Thermal management design should account for this value when calculating junction temperature under operating conditions. Refer to detailed thermal analysis for your specific application requirements.

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

A: Both parts carry MSL 2A rating with a 4-week floor life. Storage and handling must comply with IPC-A-610 moisture sensitivity guidelines for 2A classification components.

Q: Can these LEDs be operated at currents below 65mA?

A: Yes. The test current of 65mA is the reference condition for flux specification. These LEDs can operate at currents below 65mA; however, flux output will be proportionally reduced. Consult detailed I-V characteristics for operation outside the test current specification.
