Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX6SWT-H1-0000-000DB3 is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 2-SMD, Gull Wing configuration
• Physical dimensions: 5.00mm x 5.00mm footprint
• Height - Seated (Max): 1.48mm
• Thermal Resistance: 5°C/W

Optical Compatibility:

• Color: White
• Viewing Angle: 120°

Electrical Characteristics:

• Forward voltage (Vf): 20V typical
• Test current: 60mA
• Luminous flux @ 25°C: 111lm (107lm ~ 114lm range)
• Lumens/Watt efficiency: 93 lm/W

The substitute part MX6AWT-H1-0000-000DB1 shares identical mechanical dimensions, thermal properties, optical characteristics, and luminous output specifications. However, it operates at significantly different electrical parameters (3.3V forward voltage, 300mA test current), requiring circuit redesign for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000DB1 is the designated substitute for the obsolete MX6SWT-H1-0000-000DB3 based on product status and regulatory compliance. The MX6AWT maintains active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment.

Both parts share identical mechanical footprints, thermal characteristics, and luminous output specifications. The MX6AWT delivers superior lumens-per-watt efficiency (112 lm/W versus 93 lm/W), though this advantage is offset by substantially different electrical operating parameters.

Direct pin-for-pin substitution is not feasible due to the 20V-to-3.3V forward voltage differential and the 60mA-to-300mA current increase. Circuit redesign of the LED driver and current-limiting network is required to accommodate the MX6AWT's lower voltage and higher current requirements.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000DB1 be used as a direct replacement without circuit modification?

A: No. The MX6AWT operates at 3.3V forward voltage and 300mA test current, compared to the MX6SWT's 20V and 60mA specifications. The LED driver circuit must be redesigned to supply the correct voltage and current levels.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use a 5.00mm x 5.00mm footprint with 1.48mm maximum seated height, enabling PCB layout reuse. However, the MX6AWT features an exposed pad variant of the 2-SMD Gull Wing package, which may require thermal management considerations in high-power applications.

Q: What is the luminous output difference between these parts?

A: Both parts deliver 111 lumens at their respective test currents (60mA for MX6SWT, 300mA for MX6AWT). The MX6AWT achieves higher efficiency at 112 lm/W compared to the MX6SWT's 93 lm/W.

Q: Is the MX6AWT compliant with current regulatory standards?

A: Yes. The MX6AWT-H1-0000-000DB1 is RoHS compliant and maintains active product status, ensuring regulatory alignment and procurement continuity.

Q: What are the thermal characteristics of both parts?

A: Both parts have identical thermal resistance of 5°C/W and share the same MSL rating of 2A (4 Weeks), indicating equivalent thermal management and moisture handling requirements.
