Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000D51 is identified as a substitute for the MX6SWT-H1-0000-000E51 based on the following allowable parameters:

Common Electrical Characteristics:

• Color and CCT: Both parts are white LEDs with 6500K cool color temperature
• CRI: Both maintain CRI of 80
• Viewing Angle: Both provide 120° viewing angle
• Thermal Resistance: Both feature 5°C/W thermal resistance

Common Mechanical Characteristics:

• Mounting Type: Both are surface mount components
• Physical Dimensions: Both measure 5.00mm x 5.00mm
• Height - Seated (Max): Both are 1.48mm maximum
• Package Style: Both use 2-SMD, Gull Wing configuration

Differing Parameters Requiring Circuit Evaluation:

• Voltage - Forward (Vf): MX6SWT operates at 20V; MX6AWT operates at 3.3V
• Current - Test: MX6SWT at 60mA; MX6AWT at 300mA
• Current - Max: MX6SWT at 175mA; MX6AWT at 1A
• Flux Output: MX6SWT at 118lm; MX6AWT at 111lm
• Lumens/Watt: MX6SWT at 98 lm/W; MX6AWT at 112 lm/W

Substitution is valid only when the application circuit can accommodate the different voltage and current requirements of the MX6AWT series.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000D51 is the designated substitute for the obsolete MX6SWT-H1-0000-000E51. The MX6AWT maintains active product status with current manufacturing support from CreeLED, Inc., ensuring long-term availability and supply chain continuity.

Both parts share identical color temperature (6500K), CRI (80), viewing angle (120°), physical dimensions (5.00mm x 5.00mm), and thermal characteristics (5°C/W). The MX6AWT additionally provides RoHS compliance certification, meeting modern regulatory requirements.

The primary design consideration is the significant difference in forward voltage (20V vs. 3.3V) and operating current (60mA vs. 300mA). Circuit redesign of the LED drive circuit is required to accommodate the MX6AWT's lower voltage and higher current specifications. The MX6AWT delivers superior luminous efficacy (112 lm/W vs. 98 lm/W), resulting in improved energy efficiency despite comparable flux output.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000D51 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000E51?

A: No. While both parts share identical physical dimensions, color temperature, and viewing angle, the MX6AWT requires a different drive circuit. The MX6SWT operates at 20V/60mA, while the MX6AWT operates at 3.3V/300mA. The application circuit must be redesigned to supply the correct voltage and current to the substitute part.

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

A: Substitution is based on matching color (white), color temperature (6500K), CRI (80), viewing angle (120°), mounting type (surface mount), physical dimensions (5.00mm x 5.00mm), and thermal resistance (5°C/W). Voltage and current specifications are application-dependent and do not prevent substitution if the circuit is redesigned accordingly.

Q: Are there packaging differences between these parts?

A: Yes. The MX6SWT uses a 2-SMD, Gull Wing package, while the MX6AWT uses a 2-SMD, Gull Wing Exposed Pad package. The exposed pad on the MX6AWT provides improved thermal management. Both packages maintain the same 5.00mm x 5.00mm footprint and 1.48mm maximum height, allowing PCB layout compatibility.

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

A: The MX6SWT is classified as obsolete, indicating discontinued manufacturing and limited availability. The MX6AWT is active, meaning it is currently manufactured and supported by CreeLED, Inc., ensuring reliable supply and technical support for new designs.

Q: Does the MX6AWT meet modern compliance standards?

A: Yes. The MX6AWT is RoHS compliant, meeting current regulatory requirements for hazardous substance restrictions. Both parts are REACH unaffected and carry ECCN EAR99 classification.
