Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-R250-000AB8 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, Gull Wing), physical dimensions (5.00mm x 5.00mm), and mounting height (1.48mm max) must match to ensure PCB assembly compatibility without design modification.

Optical Compatibility: Color (White) and viewing angle (120°) must remain consistent to preserve optical performance in the application.

Electrical Compatibility: Forward voltage (Vf), test current, and maximum current ratings must be evaluated against circuit design requirements. Flux output at test conditions should provide equivalent or superior luminous performance.

Environmental & Compliance: Thermal resistance (5°C/W), moisture sensitivity level (MSL 2A), and REACH status must align with application thermal management and regulatory requirements.

The MX6AWT-H1-R250-000AB8 qualifies as a substitute based on matching mechanical envelope, optical characteristics, and environmental specifications, despite differences in electrical operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-R250-000AB8 is available as an Active product from CreeLED, Inc., providing supply chain continuity compared to the Obsolete MX6SWT-H1-R250-000AB8. Both parts maintain identical REACH Unaffected status and MSL 2A classification, ensuring equivalent environmental and regulatory compliance.

Substitution requires circuit-level evaluation due to significant differences in electrical operating parameters. The MX6AWT operates at 3.3V typical forward voltage with 300mA test current, compared to the MX6SWT's 20V and 60mA specifications. Both parts deliver equivalent flux output (91lm) at their respective test conditions, with the MX6AWT demonstrating superior efficiency at 92 lm/W versus 76 lm/W.

Mechanical and optical compatibility is confirmed: both parts share identical 5.00mm x 5.00mm footprint, 1.48mm maximum seated height, 120° viewing angle, and 5°C/W thermal resistance. The MX6AWT includes an exposed pad variant of the 2-SMD, Gull Wing package, which may provide enhanced thermal performance in applications requiring improved heat dissipation.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000AB8 directly replace the MX6SWT-H1-R250-000AB8 without circuit modification?

A: Direct replacement is not possible without circuit redesign. The MX6AWT operates at 3.3V forward voltage compared to the MX6SWT's 20V specification. Power supply voltage, current limiting resistors, and driver circuitry must be recalculated for the substitute part's electrical characteristics.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts share the same 5.00mm x 5.00mm footprint and 1.48mm maximum seated height, enabling identical PCB layout and assembly processes without mechanical modification.

Q: What is the difference between "2-SMD, Gull Wing" and "2-SMD, Gull Wing Exposed Pad" packaging?

A: The MX6AWT includes an exposed thermal pad beneath the component, which provides a direct thermal path to the PCB. This enhances heat dissipation in applications with elevated ambient temperatures or high-power operation. The MX6SWT does not include this exposed pad feature.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts carry REACH Unaffected status and MSL 2A (4 Weeks) moisture sensitivity classification, confirming equivalent environmental handling and regulatory compliance.

Q: Why does the MX6AWT have higher lumens per watt efficiency?

A: The MX6AWT achieves 92 lm/W at its 300mA test condition, compared to 76 lm/W for the MX6SWT at 60mA. This reflects the different operating points and LED die technology between the MX-6 and MX-6S series, not a direct performance advantage at equivalent power levels.

Q: Is the MX6AWT suitable for high-current applications?

A: The MX6AWT supports a maximum current rating of 1A, compared to 175mA for the MX6SWT. Applications requiring higher current capacity may benefit from the MX6AWT's increased current handling capability, provided thermal management is adequate.
