Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000CA2 is identified as a substitute for the MX6SWT-A1-0000-000CA2 based on the following allowable parameter alignment:

Matching Parameters:

• Color and CCT: Both White, Neutral 4750K
• Flux output: Both 104lm (100lm ~ 107lm) at 25°C
• CRI: Both 75 (Typ)
• Viewing angle: Both 120°
• Package footprint: Both 2-SMD, Gull Wing configuration
• Physical dimensions: Both 5.00mm x 5.00mm
• Height: Both 1.48mm maximum seated height
• Thermal resistance: Both 5°C/W
• Moisture sensitivity: Both 2A (4 Weeks)
• Manufacturer: Both CreeLED, Inc.

Differing Parameters:

• Forward voltage: MX6SWT operates at 20V; MX6AWT operates at 3.3V
• Test current: MX6SWT at 60mA; MX6AWT at 300mA
• Maximum current: MX6SWT 175mA; MX6AWT 1A
• Lumens/Watt efficiency: MX6SWT 87 lm/W; MX6AWT 105 lm/W
• Product status: MX6SWT is obsolete; MX6AWT is active
• Packaging format: MX6SWT loose; MX6AWT in Tape & Reel
• RoHS compliance: MX6AWT explicitly RoHS compliant

Substitution is valid when circuit design accommodates the lower forward voltage (3.3V vs 20V) and higher operating current (300mA vs 60mA) of the MX6AWT variant.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000CA2 is the active production equivalent for the obsolete MX6SWT-A1-0000-000CA2. Selection of the MX6AWT is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• RoHS compliance certification meeting current regulatory requirements
• Identical optical output (104lm, 4750K, 75 CRI, 120° viewing angle) and thermal characteristics
• Compatible footprint and package dimensions for direct PCB layout reuse
• Higher efficiency rating (105 lm/W vs 87 lm/W)

Circuit redesign is required to accommodate the voltage and current differences. The MX6AWT operates at 3.3V with 300mA test current, compared to the MX6SWT's 20V at 60mA. Driver and power supply modifications are necessary for successful substitution.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000CA2 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000CA2?

A: No. While both parts share identical optical output, color temperature, viewing angle, and physical footprint, the forward voltage differs significantly (3.3V vs 20V). Circuit redesign of the LED driver and power supply is required. PCB layout can remain unchanged due to matching package dimensions.

Q: What are the key differences between these two parts?

A: The primary differences are forward voltage (3.3V vs 20V), test current (300mA vs 60mA), and maximum current rating (1A vs 175mA). The MX6AWT also features an exposed pad variant of the 2-SMD Gull Wing package and carries RoHS compliance certification. Both deliver identical luminous flux and color characteristics.

Q: Why is the MX6SWT classified as obsolete?

A: The MX6SWT-A1-0000-000CA2 is part of the XLamp® MX-6S series, which has been superseded by the active XLamp® MX-6 series (MX6AWT). CreeLED has transitioned production to the newer series offering improved efficiency and regulatory compliance.

Q: Are the package dimensions identical between both parts?

A: Yes. Both parts measure 5.00mm x 5.00mm with a maximum seated height of 1.48mm. The MX6AWT features an exposed pad variant, but the overall footprint remains compatible for PCB reuse.

Q: What is the thermal resistance of these LEDs?

A: Both the MX6SWT and MX6AWT have a thermal resistance of 5°C/W, indicating identical thermal performance characteristics.

Q: Does the MX6AWT meet RoHS requirements?

A: Yes. The MX6AWT-A1-0000-000CA2 is explicitly RoHS compliant. RoHS status for the MX6SWT is not specified in available documentation.
