Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000CE5 qualifies as a functional equivalent based on the following matching parameters:

Matching Criteria:

• Color and CCT: Both parts deliver neutral white light at 4000K
• Luminous Flux: Identical flux output of 104lm at test current (100-107lm range)
• CRI: Both maintain 80 CRI (Typical)
• Viewing Angle: Both provide 120° beam angle
• Package Geometry: Identical 2-SMD, Gull Wing Exposed Pad configuration with 5.00mm x 5.00mm footprint and 1.48mm seated height
• Mounting Type: Both are surface mount components
• MSL Rating: Both rated 2A (4 Weeks)

Differing Parameters: The MX6AWT operates at significantly lower forward voltage (3.3V vs. 10.7V) and higher test current (300mA vs. 115mA), resulting in different power supply requirements and thermal characteristics. The MX6AWT also features improved thermal resistance (5°C/W vs. 11°C/W) and higher maximum current rating (1A vs. 175mA).

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000CE5 is the designated substitute for the obsolete MX3SWT-A1-0000-000CA4. Selection of the MX6AWT requires circuit redesign to accommodate the lower forward voltage (3.3V vs. 10.7V) and higher test current (300mA vs. 115mA). Both parts share identical optical output (104lm, 4000K, 80 CRI, 120° viewing angle) and physical footprint, enabling direct PCB layout compatibility.

The MX6AWT offers active product status, ensuring long-term availability and supply chain continuity. The part carries RoHS compliance certification, meeting current environmental regulatory requirements. Thermal performance is improved in the MX6AWT due to lower thermal resistance (5°C/W vs. 11°C/W), providing better heat dissipation in high-current applications.

Power supply and current-limiting circuit modifications are mandatory when transitioning from MX3SWT to MX6AWT due to the significant voltage and current differences. Both parts maintain identical MSL ratings and package geometry, eliminating assembly process changes.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000CE5 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000CA4?

A: The MX6AWT provides identical optical output (luminous flux, color temperature, CRI, viewing angle) and physical footprint, enabling direct PCB layout compatibility. However, circuit redesign is required due to different electrical operating parameters (3.3V vs. 10.7V forward voltage; 300mA vs. 115mA test current). The parts are not electrically interchangeable without power supply and current-limiting modifications.

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

A: The primary differences are forward voltage, test current, and thermal resistance. The MX3SWT operates at 10.7V and 115mA, while the MX6AWT operates at 3.3V and 300mA. The MX6AWT features superior thermal resistance (5°C/W vs. 11°C/W) and higher maximum current capability (1A vs. 175mA). Optical performance (flux, color, CRI) is identical.

Q: Are both parts available in the same package configuration?

A: Yes. Both the MX3SWT-A1-0000-000CA4 and MX6AWT-A1-0000-000CE5 use identical 2-SMD, Gull Wing Exposed Pad packaging with 5.00mm x 5.00mm footprint and 1.48mm seated height. No PCB layout modifications are necessary for component placement.

Q: What is the product status difference, and why does it matter?

A: The MX3SWT is classified as obsolete, indicating end-of-life status and limited future availability. The MX6AWT is active, ensuring continued manufacturing and supply chain support. For new designs and production continuity, the MX6AWT is the appropriate selection.

Q: Does the MX6AWT meet current compliance standards?

A: The MX6AWT-A1-0000-000CE5 is RoHS compliant. Both parts are REACH unaffected and carry EAR99 ECCN classification. Compliance documentation should be verified with the manufacturer for specific application requirements.
