Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000CA4 is identified as a substitute for the MX6SWT-H1-0000-000DA4 based on the following allowable parameters:

Common Electrical & Optical Characteristics:

• Color and CCT: Both are white neutral 4000K LEDs
• CRI: Both maintain 80 color rendering index
• Viewing Angle: Both provide 120° viewing angle
• Package Footprint: Both use 2-SMD, Gull Wing configuration with identical 5.00mm × 5.00mm dimensions
• Physical Height: Both have 1.48mm seated height
• Thermal Resistance: Both rated at 5°C/W

Allowable Substitution Parameters: The MX6AWT operates at significantly different electrical parameters (3.3V forward voltage, 300mA test current) compared to the MX6SWT (20V, 60mA). This substitution is valid only when circuit design accommodates the different voltage and current requirements. The MX6AWT delivers higher efficiency (105 lm/W vs. 93 lm/W) and higher maximum current rating (1A vs. 175mA), with active product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

For MX6SWT-H1-0000-000DA4 Replacement:

The MX6AWT-H1-0000-000CA4 is suitable as a substitute when the following conditions are met:

1. Circuit Voltage Compatibility: The design must accommodate 3.3V forward voltage operation instead of 20V. This requires circuit redesign or verification that the power supply and current-limiting circuitry can operate at the lower voltage.

2. Current Management: The substitute operates at 300mA test current versus 60mA for the original part. Verify that current-limiting resistors and thermal management are adjusted accordingly.

3. Product Status Advantage: The MX6AWT is active production status, ensuring long-term availability and supply chain continuity compared to the obsolete MX6SWT.

4. Compliance: The MX6AWT carries RoHS compliance certification, meeting regulatory requirements for new designs and production batches.

5. Mechanical Compatibility: Both parts share identical footprint, height, and thermal characteristics, allowing direct PCB layout reuse without modification.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000CA4 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000DA4?

A: No. While both parts share identical mechanical dimensions (5.00mm × 5.00mm footprint, 1.48mm height) and optical characteristics (4000K, 120° viewing angle, CRI 80), they operate at fundamentally different electrical parameters. The MX6AWT requires 3.3V forward voltage and 300mA test current, whereas the MX6SWT operates at 20V and 60mA. Circuit redesign is necessary to accommodate these differences.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution between these parts is based on matching: color temperature (4000K), color rendering index (80), viewing angle (120°), package configuration (2-SMD Gull Wing), physical dimensions (5.00mm × 5.00mm), and thermal resistance (5°C/W). Electrical parameters (voltage and current) must be independently verified for circuit compatibility.

Q: Why is the MX6AWT more efficient than the MX6SWT?

A: The MX6AWT delivers 105 lm/W compared to 93 lm/W for the MX6SWT at their respective test currents. This efficiency difference reflects different LED die designs and operating points between the MX-6 and MX-6S series.

Q: What is the difference between the package designations "2-SMD, Gull Wing" and "2-SMD, Gull Wing Exposed Pad"?

A: The MX6AWT includes an exposed pad for enhanced thermal dissipation, while the MX6SWT uses standard gull wing leads. Both maintain identical external dimensions and PCB footprint compatibility.

Q: Is the MX6AWT suitable for new designs?

A: Yes. The MX6AWT is active production status with RoHS compliance, making it appropriate for new product development and long-term production requirements.
