Substitute Part Grouping Explanation
Substitution of the MX6SWT-A1-0000-000AB7 is determined by the following critical parameters:
- Color: White (both main and substitute parts)
- Viewing Angle: 120° (maintained across all parts)
- Package Type: 2-SMD, Gull Wing configuration (physical compatibility)
- Physical Dimensions: 5.00 mm × 5.00 mm footprint and 1.48 mm maximum height (PCB layout compatibility)
- Thermal Resistance: 5°C/W (thermal management equivalence)
- Luminous Flux Output: 91 lm nominal at test conditions (functional performance)
- Moisture Sensitivity Level: 2A (4 Weeks) (handling and storage requirements)
The MX6AWT-A1-0000-000AB7 qualifies as a substitute based on matching these core parameters. However, the substitute operates at different electrical specifications (3.3V forward voltage, 300 mA test current) and belongs to the XLamp® MX-6 series rather than MX-6S. Circuit design must accommodate these electrical differences.

Engineering Selection Recommendations
The MX6AWT-A1-0000-000AB7 is available as an active product from CreeLED, Inc., whereas the MX6SWT-A1-0000-000AB7 is obsolete. Both parts maintain identical physical footprints, viewing angles, thermal characteristics, and nominal luminous flux output, enabling direct PCB layout compatibility.
The primary design consideration is electrical specification. The substitute operates at 3.3V forward voltage with 300 mA test current, compared to the main part's 20V and 60 mA specifications. Circuit topology, current limiting, and power supply design must be revised to accommodate the lower voltage and higher current requirements of the MX6AWT-A1-0000-000AB7.
The substitute part carries RoHS compliance certification, whereas compliance status is not specified for the obsolete main part. For applications subject to RoHS requirements, the MX6AWT-A1-0000-000AB7 provides documented regulatory compliance.
Frequently Asked Questions (FAQ)
Q: Can the MX6AWT-A1-0000-000AB7 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000AB7?
A: Physical compatibility is confirmed. Both parts share identical 5.00 mm × 5.00 mm footprints, 1.48 mm maximum height, 120° viewing angle, and 2-SMD Gull Wing package configuration. However, electrical circuit redesign is required due to different forward voltage (3.3V vs. 20V) and test current (300 mA vs. 60 mA) specifications.
Q: What are the key parameters that determine substitution eligibility?
A: Substitution is based on color (white), viewing angle (120°), physical dimensions (5.00 mm × 5.00 mm), package type (2-SMD Gull Wing), height (1.48 mm maximum), thermal resistance (5°C/W), luminous flux output (91 lm nominal), and moisture sensitivity level (2A, 4 Weeks).
Q: Does the substitute part have better efficiency?
A: The MX6AWT-A1-0000-000AB7 achieves 92 lm/W at its test current, compared to 76 lm/W for the MX6SWT-A1-0000-000AB7. This represents improved luminous efficacy at the substitute's operating point.
Q: Are there packaging differences between these parts?
A: The main part uses a standard 2-SMD Gull Wing package. The substitute features a 2-SMD Gull Wing Exposed Pad configuration, which provides enhanced thermal dissipation through the exposed pad connection to PCB ground or thermal planes.
Q: What compliance certifications apply to the substitute part?
A: The MX6AWT-A1-0000-000AB7 is RoHS Compliant. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.
