Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-0009A9 serves as the active production equivalent to the obsolete MX6SWT-A1-0000-0009A9. Both components deliver identical photometric output (84lm at 2850K with 80 CRI) and share mechanical compatibility (5.00mm x 5.00mm footprint, 1.48mm height, 120° viewing angle).

The primary design consideration is the voltage and current operating point. The MX6AWT operates at 3.3V with 300mA test current versus the MX6SWT's 20V at 60mA. This represents a fundamental difference in LED architecture and requires circuit redesign. The MX6AWT achieves superior efficiency (85 lm/W versus 70 lm/W), reflecting advances in LED technology between the MX-6S and MX-6 series.

The MX6AWT is RoHS Compliant and supplied in Tape & Reel packaging, supporting modern manufacturing workflows. Both components maintain identical thermal resistance (5°C/W) and moisture sensitivity ratings (2A, 4 Weeks).

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-0009A9 be used as a direct drop-in replacement for the MX6SWT-A1-0000-0009A9?

A: No. While both LEDs deliver identical light output (84lm, 2850K, 80 CRI) and share the same 5.00mm x 5.00mm footprint, they operate at different voltage and current levels. The MX6SWT requires 20V at 60mA, while the MX6AWT requires 3.3V at 300mA. Circuit redesign is necessary, including modifications to current-limiting resistors and power supply architecture.

Q: Are the mechanical packages compatible?

A: Both components use 2-SMD, Gull Wing surface mount packages with identical 5.00mm x 5.00mm dimensions and 1.48mm seated height. The MX6AWT includes an exposed pad, which may provide improved thermal performance in applications requiring enhanced heat dissipation. PCB footprints are compatible.

Q: What is the significance of the product status difference?

A: The MX6SWT is classified as obsolete, indicating CreeLED has discontinued production. The MX6AWT is active production, ensuring long-term availability and supply chain stability. For new designs or production continuity, the MX6AWT is the recommended selection.

Q: How do the efficiency ratings compare?

A: The MX6AWT delivers 85 lm/W versus the MX6SWT's 70 lm/W at their respective test currents. This 21% efficiency improvement reflects technological advancement in the MX-6 series. At equivalent light output, the MX6AWT consumes less power.

Q: Are there compliance or regulatory differences?

A: Both components are REACH Unaffected. The MX6AWT is RoHS Compliant, while RoHS status is not specified for the obsolete MX6SWT. Both maintain identical MSL ratings (2A, 4 Weeks) and thermal resistance (5°C/W).

Q: What packaging formats are available?

A: The MX6SWT is supplied loose. The MX6AWT is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and reduces handling risk during manufacturing.
