Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000EB2 is evaluated based on the following critical parameters:

Mechanical Compatibility: Package type (2-SMD Gull Wing), footprint dimensions (5.00mm x 5.00mm), and maximum seated height (1.48mm) must remain identical to ensure PCB assembly compatibility without design modification.

Optical Compatibility: Color (White) and viewing angle (120°) must match the original specification to maintain system optical performance.

Thermal Compatibility: Thermal resistance of package (5°C/W) establishes the thermal management baseline for the application.

Electrical Compatibility: Forward voltage (Vf), test current, and maximum current ratings determine circuit design feasibility. Substitutes must operate within the existing power supply and current-limiting circuit parameters.

Environmental Compliance: Moisture sensitivity level (MSL 2A) and REACH status must be maintained or improved to ensure manufacturing and storage compatibility.

The identified substitute, MX6AWT-A1-0000-000DB1, shares identical mechanical, optical, and thermal characteristics with the main part. However, significant electrical parameter differences exist and must be evaluated for circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MX6SWT-A1-0000-000EB2 is Obsolete, while the MX6AWT-A1-0000-000DB1 is Active. Active product status ensures continued availability, manufacturing support, and compliance updates from CreeLED, Inc.

Compliance Advantage: The MX6AWT-A1-0000-000DB1 carries RoHS Compliant certification, whereas RoHS status is not specified for the main part. This provides regulatory advantage for applications subject to RoHS requirements.

Electrical Parameter Divergence: The substitute operates at 3.3V typical forward voltage compared to 20V for the main part. This represents a fundamental circuit design difference. The substitute requires significantly higher test current (300mA vs. 60mA) and maximum current (1A vs. 175mA). Direct substitution without circuit redesign is not feasible.

Mechanical and Thermal Equivalence: Both parts share identical footprint dimensions, seated height, thermal resistance, and viewing angle. PCB layout and thermal management design remain compatible.

Luminous Output: The substitute delivers 111lm at 300mA test current compared to 118lm at 60mA for the main part. Efficiency improves to 112 lm/W versus 98 lm/W, indicating superior performance per watt in the substitute design.

Selection of the MX6AWT-A1-0000-000DB1 requires circuit redesign to accommodate the lower forward voltage and higher current requirements. This substitution is suitable only for new designs or applications where circuit modification is feasible.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000DB1 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000EB2?

A: No. While both parts share identical mechanical footprints and thermal characteristics, the electrical parameters differ significantly. The substitute operates at 3.3V forward voltage versus 20V for the main part. Direct substitution without circuit redesign will result in component failure or malfunction. The existing current-limiting circuit and power supply must be redesigned to accommodate the lower voltage and higher current requirements of the substitute.

Q: What are the key mechanical compatibility factors?

A: Both parts are housed in 2-SMD Gull Wing surface mount packages with identical dimensions (5.00mm x 5.00mm) and maximum seated height (1.48mm). PCB footprints are compatible. The substitute features an exposed pad variant, which may provide improved thermal performance in high-power applications but does not affect mechanical compatibility.

Q: Are there packaging differences between these parts?

A: Yes. The MX6SWT-A1-0000-000EB2 is supplied in bulk packaging, while the MX6AWT-A1-0000-000DB1 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides better handling and storage characteristics for production environments.

Q: What is the significance of the RoHS Compliant status on the substitute?

A: RoHS Compliance indicates the substitute meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. This is advantageous for applications subject to RoHS requirements or for future regulatory compliance. The main part does not specify RoHS status.

Q: How do the luminous outputs compare?

A: The main part delivers 118lm at 60mA test current (98 lm/W efficiency). The substitute delivers 111lm at 300mA test current (112 lm/W efficiency). The substitute achieves higher efficiency per watt but operates at significantly higher current levels. Luminous output is comparable, but the operating point differs substantially.

Q: Why is the main part classified as Obsolete?

A: Obsolete status indicates the XLamp® MX-6S series has reached end-of-life. CreeLED, Inc. has transitioned to newer product lines, including the XLamp® MX-6 series represented by the substitute part. Obsolete classification typically means no new manufacturing is occurring, though existing inventory may remain available.

Q: What thermal considerations apply to substitution?

A: Both parts have identical thermal resistance of 5°C/W. However, the substitute's exposed pad design may provide marginally improved thermal performance in applications with direct thermal coupling to the PCB. Thermal management design remains compatible between the two parts.
