Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000CB5 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD Gull Wing), physical dimensions (5.00mm x 5.00mm), and height (1.48mm maximum) must match to ensure PCB footprint compatibility.

Optical Characteristics: Color (White) and viewing angle (120°) must remain constant for optical performance in the application.

Thermal Properties: Thermal resistance of 5°C/W must be maintained for thermal management consistency.

Electrical Operating Point: While forward voltage and test current differ between the main part and substitute, the substitute must operate within the same general application class and deliver comparable luminous flux output at its specified test conditions.

The MX6AWT-A1-0000-000CB3 meets these substitution criteria through identical mechanical packaging, matching optical specifications, equivalent thermal characteristics, and comparable luminous output, despite operating at different voltage and current levels.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000CB3 is the designated substitute for the obsolete MX6SWT-A1-0000-000CB5. Selection is based on the following factors:

Product Status: The MX6AWT-A1-0000-000CB3 maintains Active status with current manufacturing support, ensuring long-term availability and supply chain continuity.

Compliance: The MX6AWT-A1-0000-000CB3 is RoHS Compliant, meeting modern regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Mechanical and Optical Equivalence: Identical package footprint, dimensions, height, thermal resistance, and optical characteristics (color, viewing angle) ensure direct PCB compatibility and optical performance parity.

Luminous Output: Both parts deliver 104lm at their respective test conditions, maintaining equivalent brightness in the application.

Electrical Redesign Requirement: Circuit redesign is necessary due to the significant difference in forward voltage (20V versus 3.3V) and test current (60mA versus 300mA). The substitute operates at substantially lower voltage with higher current, requiring corresponding adjustments to current-limiting resistors and power supply specifications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000CB3 be used as a direct drop-in replacement without circuit modification?

A: No. While the mechanical package and optical characteristics are identical, the electrical operating point differs significantly. The MX6AWT-A1-0000-000CB3 operates at 3.3V typical forward voltage compared to 20V for the MX6SWT-A1-0000-000CB5. Circuit redesign of the current-limiting network and power supply is required.

Q: Are the physical footprints identical?

A: Yes. Both parts use 2-SMD Gull Wing packaging with identical dimensions (5.00mm x 5.00mm) and maximum seated height (1.48mm). PCB footprints are compatible. The MX6AWT-A1-0000-000CB3 includes an exposed pad variant, which may provide improved thermal performance in high-power applications.

Q: Do both parts have the same luminous output?

A: Yes. Both parts deliver 104lm at their specified test conditions (100lm to 107lm range). Brightness in the application will be equivalent when properly driven at their respective rated currents.

Q: What is the difference between the package designations?

A: The MX6SWT-A1-0000-000CB5 uses standard 2-SMD Gull Wing packaging. The MX6AWT-A1-0000-000CB3 uses 2-SMD Gull Wing with an Exposed Pad, which provides additional thermal dissipation capability through direct contact with the PCB ground plane.

Q: Are there compliance or regulatory differences?

A: The MX6AWT-A1-0000-000CB3 is explicitly RoHS Compliant, while the MX6SWT-A1-0000-000CB5 does not specify RoHS status. Both maintain REACH Unaffected classification and EAR99 export status.

Q: Why is the MX6SWT-A1-0000-000CB5 obsolete?

A: The part is classified as Obsolete by the manufacturer. The MX6AWT-A1-0000-000CB3 from the newer XLamp® MX-6 series provides equivalent functionality with improved efficiency (105 lm/W versus 87 lm/W) and Active product status.
