Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000DF4 is identified as a substitute for the MX6SWT-H1-0000-000EF4 based on the following substitution criteria:

Matching Parameters:

• Color and CCT: Both parts are White, Neutral 4750K
• CRI: Both maintain CRI 80
• Viewing Angle: Both provide 120° viewing angle
• Package Footprint: Both use 2-SMD, Gull Wing configuration with identical 5.00mm x 5.00mm dimensions
• Height: Both have 1.48mm maximum seated height
• Thermal Resistance: Both rated at 5°C/W
• Mounting Type: Both are surface mount
• MSL Rating: Both classified as 2A (4 Weeks)

Differing Parameters: The substitute part operates at significantly different electrical parameters: 3.3V forward voltage and 300mA test current, compared to the original 20V and 60mA. This represents a different electrical class within the XLamp® family (MX-6 versus MX-6S). The substitute delivers 111lm at its test current with improved efficiency (112 lm/W versus 98 lm/W).

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000DF4 is suitable as a substitute where the application can accommodate the different electrical operating point (3.3V, 300mA versus 20V, 60mA). The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability compared to the obsolete original part. Both parts share identical mechanical footprints, thermal characteristics, and optical properties (color, CRI, viewing angle), enabling direct PCB layout compatibility.

The substitute part carries RoHS compliance certification, providing regulatory advantage for applications subject to RoHS requirements. The exposed pad variant of the substitute may offer improved thermal performance in high-power applications through enhanced heat dissipation pathways.

Selection between these parts depends entirely on circuit voltage and current requirements. Applications designed for 20V operation require the original part or alternative 20V-class neutral white LEDs. Applications operating at 3.3V logic levels or low-voltage power supplies should transition to the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000DF4 be used as a direct replacement in existing designs?

A: Direct replacement is possible only if the circuit design can be modified to accommodate 3.3V forward voltage and 300mA operating current. The PCB footprint is identical, but power supply and current limiting circuitry must be redesigned. The parts are not interchangeable without circuit modification.

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

A: Both packages share identical external dimensions (5.00mm x 5.00mm, 1.48mm height) and mounting footprints. The exposed pad variant on the substitute part provides an additional thermal connection point to the PCB, improving heat dissipation in applications requiring higher power density or thermal management.

Q: Why is the original part classified as obsolete?

A: Product obsolescence indicates that CreeLED, Inc. has discontinued manufacturing the MX6SWT-H1-0000-000EF4. The substitute part (MX6AWT-H1-0000-000DF4) remains in active production, making it the recommended path for new designs and long-term supply continuity.

Q: Are there electrical compatibility concerns between these parts?

A: Yes. The original part requires 20V forward voltage; the substitute requires 3.3V. These represent different electrical classes and cannot be used interchangeably without complete circuit redesign. Applying 20V to the substitute part will cause immediate failure.

Q: Do both parts have the same color temperature and CRI?

A: Yes. Both parts are specified as White, Neutral 4750K with CRI 80, ensuring identical color characteristics and rendering properties in lighting applications.

Q: What is the significance of the MSL 2A rating?

A: MSL 2A indicates Moisture Sensitivity Level 2A, requiring storage in controlled humidity conditions (≤60% RH) with a shelf life of 4 weeks after opening. Both parts share this specification, requiring identical moisture control procedures during handling and assembly.
