SPMWHT541ML5XAVKS6 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541ML5XAVKS6 is a Samsung Semiconductor LM561C series warm white LED designed for general lighting applications. This 5630 package surface mount LED operates at 3000K color temperature with a forward voltage of 2.75V and test current of 65mA, delivering 36 lumens at 201 lm/W efficiency. The component is currently active in production and RoHS compliant, making it suitable for new designs and existing applications requiring warm white LED solutions with high color rendering index (CRI 80).

Substitute parts are identified when inventory constraints, supply chain disruptions, or procurement requirements necessitate alternative sourcing while maintaining identical electrical and mechanical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541ML5XAVKS6 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Series designation: LM561C
• Color and color temperature: White, Warm 3000K
• Luminous flux range: 35–37 lm at 25°C, 65mA test current
• Forward voltage: 2.75V typical
• Maximum current rating: 200mA
• Package configuration: 4-SMD, Flat Leads (5630)
• Physical dimensions: 5.00mm × 3.00mm, 0.80mm maximum height
• Viewing angle: 120°
• Color rendering index: 80
• Thermal resistance: 12°C/W

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Variations in inventory status, RoHS certification revision level, or packaging format (Tape & Reel) do not affect functional substitutability.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAVMS6 be used as a direct replacement for SPMWHT541ML5XAVKS6?

A: Yes. Both parts are parametrically identical across all electrical, optical, and mechanical specifications. They operate at the same forward voltage (2.75V), test current (65mA), luminous flux (36 lm), color temperature (3000K), and package dimensions (5.00 × 3.00 × 0.80mm). No circuit modifications or PCB layout changes are required.

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

A: ROHS3 represents a more recent revision of the RoHS directive with updated substance restrictions. Both certifications indicate compliance with hazardous substance limitations. ROHS3 Compliant parts meet current regulatory requirements and are suitable for new designs. The functional performance of the LED is identical under both certifications.

Q: Are these parts interchangeable in existing production?

A: Yes. The parts are mechanically and electrically interchangeable. Both use the same 5630 package with 4-SMD flat leads, identical pin configuration, and identical performance characteristics. No design changes are necessary for substitution.

Q: What is the significance of the 120° viewing angle?

A: The 120° viewing angle defines the half-angle at which luminous intensity drops to 50% of the peak value. This specification is identical for both parts and affects light distribution in the application. Ensure the viewing angle matches the optical design requirements of your application.

Q: Can these LEDs operate at currents other than 65mA?

A: Yes. The maximum rated current is 200mA. However, the specified luminous flux of 36 lm is measured at the 65mA test current. Operation at different currents will produce different light output levels. Thermal management must account for increased power dissipation at higher currents.

Q: What is the thermal resistance specification used for?

A: The 12°C/W thermal resistance indicates the temperature rise of the LED junction above ambient for each watt of power dissipated. At 65mA and 2.75V, power dissipation is approximately 0.179W. Thermal design calculations use this parameter to ensure the LED operates within safe junction temperature limits.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both SPMWHT541ML5XAVKS6 and SPMWHT541ML5XAVMS6 are supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly processes.
