Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000AE8 is identified as a substitute for the MX3SWT-A1-0000-000AE8 based on the following substitution criteria:

Matching Parameters:

• Color and CCT: Both are warm white at 2700K
• Flux Output: Both deliver 91 lm at 25°C (87–94 lm range)
• CRI: Both maintain 80 (Typ)
• Viewing Angle: Both provide 120° beam angle
• Package / Case: Both use 2-SMD, Gull Wing Exposed Pad
• Physical Dimensions: Both measure 5.00 mm × 5.00 mm
• Height: Both have 1.48 mm seated height
• Moisture Sensitivity: Both rated 2A (4 Weeks)

Differing Parameters:

• Forward Voltage: MX6AWT operates at 3.3V (vs. 10.7V for MX3SWT)
• Test Current: MX6AWT uses 300 mA (vs. 115 mA for MX3SWT)
• Maximum Current: MX6AWT rated to 1A (vs. 175 mA for MX3SWT)
• Lumens/Watt: MX6AWT achieves 92 lm/W (vs. 74 lm/W for MX3SWT)
• Thermal Resistance: MX6AWT is 5°C/W (vs. 11°C/W for MX3SWT)
• Product Status: MX6AWT is Active (vs. Obsolete for MX3SWT)

Substitution is valid when the application can accommodate the lower forward voltage and higher current requirements of the MX6AWT, while maintaining identical optical output and color characteristics.

Engineering Selection Recommendations

The MX6AWT-A1-0000-000AE8 is the designated substitute for the obsolete MX3SWT-A1-0000-000AE8. Selection of the MX6AWT is supported by:

• Product Status: The MX6AWT maintains active production status, ensuring supply chain continuity and long-term availability.
• Optical Equivalence: Identical flux output (91 lm) and color rendering index (80) at 2700K warm white ensure visual performance parity.
• Compliance: The MX6AWT is RoHS Compliant, meeting current regulatory requirements. Both parts maintain REACH Unaffected status.
• Mechanical Compatibility: Identical package type, footprint (5.00 mm × 5.00 mm), and height (1.48 mm) enable direct PCB layout reuse.

Critical Design Consideration: The MX6AWT operates at 3.3V forward voltage with 300 mA test current, compared to the MX3SWT's 10.7V and 115 mA. Circuit design modifications are required to accommodate this voltage and current shift. The MX6AWT's improved thermal resistance (5°C/W vs. 11°C/W) and higher efficiency (92 lm/W vs. 74 lm/W) provide thermal and power consumption benefits.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000AE8 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AE8?

A: The MX6AWT is mechanically compatible (identical package, footprint, and height) but requires circuit redesign. The forward voltage differs significantly (3.3V vs. 10.7V), and the test current is higher (300 mA vs. 115 mA). Power supply and current-limiting circuitry must be modified to accommodate these electrical differences.

Q: Are the optical characteristics identical between these two parts?

A: Yes. Both parts deliver 91 lumens at 25°C (87–94 lm range), maintain a color temperature of 2700K warm white, and provide a color rendering index of 80 with a 120° viewing angle. Optical performance is equivalent.

Q: What is the impact of the different thermal resistance values?

A: The MX6AWT has lower thermal resistance (5°C/W vs. 11°C/W), meaning it dissipates heat more efficiently. This results in lower junction temperatures under the same thermal conditions, improving reliability and potentially extending operational life.

Q: Does the MX6AWT meet current regulatory standards?

A: Yes. The MX6AWT is RoHS Compliant and maintains REACH Unaffected status, meeting current environmental and regulatory requirements. The MX3SWT's regulatory status is not fully specified in available documentation.

Q: Are there any packaging or moisture sensitivity differences?

A: No. Both parts use identical 2-SMD Gull Wing Exposed Pad packaging and are rated at Moisture Sensitivity Level 2A (4 Weeks), requiring identical handling and storage protocols.

Q: What is the efficiency advantage of the MX6AWT?

A: The MX6AWT achieves 92 lm/W compared to the MX3SWT's 74 lm/W at their respective test currents. This 24% efficiency improvement reduces power consumption for equivalent light output, lowering thermal load and operational costs.
