LED XLAMP MX3SWT-A1-0000-0008E7 Equivalent & Substitute Parts

Part Overview

The CreeLED MX3SWT-A1-0000-0008E7 is an XLamp® MX-3S warm white LED (3000K) designed for surface mount applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and design updates. The MX-3S series has been superseded by newer XLamp® MX-3 variants that maintain compatibility across key electrical and mechanical parameters while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-0008E7 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Color and CCT: White, Warm 3000K (exact match required)
• CRI: 80 (Typ) or higher
• Viewing Angle: 120° (exact match)
• Package / Case: 2-SMD, Gull Wing Exposed Pad (exact match)
• Physical Dimensions: 5.00mm x 5.00mm footprint (exact match)
• Height: 1.48mm maximum (exact match)
• Thermal Resistance: 11°C/W (exact match)
• Mounting Type: Surface Mount (exact match)

Electrical Flexibility Parameters: Forward voltage, test current, flux output, lumens/watt, and maximum current ratings may vary within the XLamp® product family while maintaining functional equivalence. These variations reflect generational improvements and do not preclude substitution when all mandatory parameters align.

The identified substitute MX3AWT-A1-R250-000AE7 belongs to the XLamp® MX-3 series and satisfies all mandatory compatibility criteria, representing an active product alternative to the obsolete MX-3S variant.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-R250-000AE7 is the qualified substitute for the obsolete MX3SWT-A1-0000-0008E7 based on the following factors:

Product Status: The substitute is classified as Active, ensuring continued availability and supply chain stability compared to the obsolete main part.

Compliance & Certifications: The MX3AWT-A1-R250-000AE7 carries RoHS Compliant status, meeting modern regulatory requirements. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

Mechanical & Optical Compatibility: Identical package configuration (2-SMD, Gull Wing Exposed Pad), footprint (5.00mm x 5.00mm), height (1.48mm), thermal resistance (11°C/W), and viewing angle (120°) ensure direct PCB compatibility without layout modifications.

Color & CRI Alignment: Both parts deliver White, Warm 3000K output with CRI 80 (Typ), maintaining identical color performance characteristics.

Electrical Differences: The substitute operates at lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA), with increased flux output (91lm vs. 77lm) and improved efficiency (70 lm/W vs. 63 lm/W). Circuit design must accommodate these electrical parameter changes through appropriate current-limiting and voltage regulation adjustments.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-R250-000AE7 be used as a direct drop-in replacement without circuit modifications?

A: No. While the mechanical and optical characteristics are identical, the electrical parameters differ significantly. The substitute requires lower forward voltage (3.7V vs. 10.7V) and operates at higher test current (350mA vs. 115mA). Circuit design modifications to current-limiting resistors and voltage regulation are necessary.

Q: Are the physical footprints identical between the main part and substitute?

A: Yes. Both components use the 2-SMD, Gull Wing Exposed Pad package with 5.00mm x 5.00mm footprint and 1.48mm maximum height. PCB layout and reflow profiles remain unchanged.

Q: What is the significance of the different series designations (MX-3S vs. MX-3)?

A: The MX-3S is an obsolete series variant, while the MX-3 is the current active generation. The MX-3 represents a generational update with improved efficiency (70 lm/W vs. 63 lm/W) and higher flux output while maintaining identical color, CRI, viewing angle, and package specifications.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The MX3AWT-A1-R250-000AE7 is RoHS Compliant and maintains REACH Unaffected status. Both parts carry EAR99 ECCN classification.

Q: What is the impact of the voltage and current differences on thermal management?

A: Both parts have identical thermal resistance (11°C/W). However, the substitute's higher current operation (350mA vs. 115mA) at lower voltage results in different power dissipation characteristics. Thermal design calculations must be recalculated based on the new operating point.

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, which is standard for production environments. The main part packaging format was not specified in the original documentation.

Q: Can both parts be used interchangeably in existing inventory?

A: No. Due to electrical parameter differences, circuit-level changes are required. Parts should not be mixed within the same production batch without explicit design validation.
