Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000BB3 qualifies as a functional substitute based on the following alignment criteria:

Matching Parameters:

• Identical color specification (White)
• Identical luminous flux output at test conditions (97 lm at 25°C)
• Identical viewing angle (120°)
• Identical package footprint (2-SMD, Gull Wing, 5.00 mm × 5.00 mm)
• Identical seated height (1.48 mm maximum)
• Identical thermal resistance (5°C/W)
• Identical moisture sensitivity level (2A, 4 Weeks)
• Identical REACH compliance status (REACH Unaffected)
• Same manufacturer (CreeLED, Inc.)

Differing Parameters: The MX6AWT operates at significantly lower forward voltage (3.3V typical) and higher test current (300 mA) compared to the MX6SWT (20V, 60 mA). These electrical differences require circuit-level evaluation to determine substitutability in specific applications. The MX6AWT is Active product status with RoHS compliance certification, whereas the MX6SWT is Obsolete with no RoHS designation provided.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000BB3 is the documented substitute for the obsolete MX6SWT-A1-0000-000BB8. Selection of the MX6AWT requires validation of the following factors:

Electrical Compatibility: The MX6AWT operates at 3.3V typical forward voltage with 300 mA test current, compared to the MX6SWT at 20V and 60 mA. Existing drive circuits designed for the MX6SWT must be re-evaluated and potentially redesigned to accommodate the lower voltage and higher current requirements of the MX6AWT.

Compliance Status: The MX6AWT carries active RoHS compliance certification, whereas the MX6SWT does not specify RoHS status. For applications subject to RoHS requirements, the MX6AWT provides documented compliance.

Mechanical Compatibility: Both parts share identical footprint dimensions (5.00 mm × 5.00 mm), seated height (1.48 mm), and thermal characteristics (5°C/W). The MX6AWT features an exposed pad variant of the 2-SMD gull wing package, which may require PCB layout adjustment for thermal management optimization.

Product Lifecycle: The MX6AWT is Active status with established supply chain availability, whereas the MX6SWT is Obsolete. Transition to the MX6AWT is recommended for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000BB3 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000BB8?

A: No. While both parts share identical mechanical footprint, viewing angle, and luminous flux output, the MX6AWT operates at significantly different electrical parameters (3.3V, 300 mA vs. 20V, 60 mA). Direct substitution without circuit redesign will result in component failure or inadequate performance. The drive circuit must be re-evaluated and modified to accommodate the MX6AWT's electrical requirements.

Q: What are the key parameters that determine substitutability between these parts?

A: Substitutability is determined by: color (White), luminous flux at test conditions (97 lm), viewing angle (120°), package footprint (5.00 mm × 5.00 mm), seated height (1.48 mm), thermal resistance (5°C/W), and moisture sensitivity level (2A). Electrical parameters (forward voltage and test current) differ significantly and require circuit-level compatibility assessment.

Q: Does the MX6AWT's exposed pad package affect PCB design?

A: The MX6AWT features an exposed pad variant compared to the standard 2-SMD gull wing package of the MX6SWT. The exposed pad provides enhanced thermal dissipation and may require PCB layout modifications to optimize thermal performance. Consult the MX6AWT datasheet for thermal pad design guidelines.

Q: Is the MX6AWT available in the same packaging format as the MX6SWT?

A: The MX6AWT is supplied in Tape & Reel (TR) packaging, whereas the MX6SWT packaging format is not specified in the provided data. Verify packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to each part?

A: The MX6AWT carries RoHS compliance certification and maintains REACH Unaffected status. The MX6SWT specifies REACH Unaffected status but does not provide RoHS certification information. For applications requiring RoHS compliance, the MX6AWT is the appropriate selection.
