Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-0000-000AB5 is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 2-SMD, Gull Wing configuration
• Physical dimensions: 5.00mm × 5.00mm footprint
• Height: 1.48mm seated maximum
• Thermal resistance: 5°C/W

Electrical Compatibility:

• Color: White
• Viewing angle: 120°
• Luminous flux output: 91 lumens nominal at test conditions
• CRI: 80 or equivalent

Operational Parameters:

• Forward voltage and test current must be compatible with circuit design requirements
• Maximum current rating must support intended application

The identified substitute, MX6AWT-H1-0000-000AB5, shares identical mechanical dimensions, thermal characteristics, and optical properties (color, viewing angle, flux output, CRI). However, it operates at fundamentally different electrical parameters: 3.3V forward voltage at 300mA test current versus the original 20V at 60mA. This electrical difference requires circuit redesign and is not a direct pin-compatible replacement.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000AB5 is the identified substitute for the obsolete MX6SWT-H1-0000-000AB5. Selection of this alternative requires the following considerations:

Product Status: The MX6AWT-H1-0000-000AB5 maintains active product status with current manufacturing and availability, addressing the obsolescence of the original part.

Compliance: The substitute carries RoHS Compliant certification, whereas the original part does not specify RoHS status. Both parts maintain REACH Unaffected status and EAR99 export classification.

Mechanical and Optical Equivalence: Identical footprint, height, thermal resistance, luminous flux output, color, and viewing angle enable direct PCB layout compatibility and equivalent optical performance.

Electrical Redesign Requirement: The substitute operates at 3.3V forward voltage with 300mA test current, compared to the original 20V at 60mA. Circuit topology, power supply, and current limiting must be redesigned to accommodate this electrical difference. The substitute is not a direct drop-in replacement from an electrical standpoint.

Efficiency Consideration: The MX6AWT-H1-0000-000AB5 delivers 92 lm/W at test current versus 76 lm/W for the original part, representing improved luminous efficiency.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000AB5 be used as a direct replacement without circuit modification?

A: No. While the parts share identical mechanical dimensions and optical properties, the electrical parameters differ significantly. The substitute requires 3.3V forward voltage at 300mA test current, whereas the original operates at 20V and 60mA. Circuit redesign is mandatory.

Q: Are the PCB footprints identical between these parts?

A: The footprints are mechanically compatible. Both use 2-SMD, Gull Wing configuration with 5.00mm × 5.00mm dimensions and 1.48mm seated height. However, the substitute features an exposed pad variant, which may provide thermal management benefits in high-power applications.

Q: What is the significance of the "Exposed Pad" designation on the substitute?

A: The exposed pad on the MX6AWT-H1-0000-000AB5 provides direct thermal contact to the PCB, improving heat dissipation. This is beneficial for applications operating at or near maximum current ratings.

Q: Does the substitute meet the same color and CRI specifications?

A: Both parts deliver white color with 91 lumens at 25°C. The original specifies CRI 80; the substitute does not specify CRI. If CRI 80 is a design requirement, this must be confirmed with the manufacturer before substitution.

Q: What is the inventory status of these parts?

A: The original MX6SWT-H1-0000-000AB5 has 1029 pieces in stock as new original inventory. The substitute MX6AWT-H1-0000-000AB5 has 752 pieces available. Both are currently available for procurement.
