Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3SWT-A1-0000-0008B9 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, Gull Wing Exposed Pad), footprint dimensions (5.00mm x 5.00mm), and maximum seated height (1.48mm) must match exactly to ensure PCB assembly compatibility without design modification.

Optical Compatibility: Color (White) and viewing angle (120°) must remain constant to preserve intended optical performance in the application.

Thermal Compatibility: Thermal resistance of package (11°C/W) establishes the thermal management baseline for the application.

Electrical Operating Range: The substitute must operate within the application's voltage and current constraints. The MX3SWT operates at 10.7V typical forward voltage with 115mA test current and 175mA maximum current rating.

Environmental Compliance: Moisture sensitivity level (2A, 4 Weeks) and REACH status must be maintained or improved to ensure manufacturing process compatibility and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-0008B4 shares identical mechanical, optical, and thermal characteristics with the MX3SWT-A1-0000-0008B9, enabling direct footprint compatibility. Both components maintain the same package configuration, dimensions, height, thermal resistance, and moisture sensitivity level.

The MX3AWT-A1-0000-0008B4 holds Active product status, ensuring continued availability and manufacturing support, whereas the MX3SWT-A1-0000-0008B9 is Obsolete. Both parts maintain REACH Unaffected compliance status.

Critical consideration: The MX3AWT operates at 3.7V typical forward voltage with 350mA test current, compared to the MX3SWT's 10.7V and 115mA. This represents a significant electrical operating point difference. Circuit design must accommodate this voltage and current differential to ensure proper LED operation and thermal management. The MX3AWT delivers equivalent luminous flux (77lm) at its specified test current, though at lower efficiency (59 lm/W versus 63 lm/W).

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0008B4 be used as a direct replacement for the MX3SWT-A1-0000-0008B9?

A: Mechanical and optical compatibility is confirmed. Both components use identical 2-SMD, Gull Wing Exposed Pad packaging with 5.00mm x 5.00mm footprints and 1.48mm maximum height. However, electrical operating parameters differ substantially. The MX3AWT requires 3.7V forward voltage and 350mA test current versus the MX3SWT's 10.7V and 115mA. Circuit redesign is necessary to accommodate these electrical differences.

Q: What are the key compatibility criteria for substitution?

A: Mechanical compatibility (package type, footprint, height), optical properties (color, viewing angle), thermal characteristics (thermal resistance), and environmental specifications (moisture sensitivity, regulatory compliance) must match or exceed the original component. Electrical operating points must be evaluated within the context of the application circuit design.

Q: Is the MX3AWT-A1-0000-0008B4 available for new designs?

A: Yes. The MX3AWT-A1-0000-0008B4 holds Active product status with current manufacturing support, whereas the MX3SWT-A1-0000-0008B9 is Obsolete. Both components maintain REACH Unaffected compliance.

Q: How do the luminous efficiency ratings compare?

A: The MX3SWT-A1-0000-0008B9 delivers 63 lm/W at its 115mA test current. The MX3AWT-A1-0000-0008B4 delivers 59 lm/W at its 350mA test current. Both achieve identical luminous flux output (77lm) at their respective test conditions, with the MX3SWT demonstrating higher efficiency per watt.

Q: Are there packaging differences between these components?

A: No. Both components use identical 2-SMD, Gull Wing Exposed Pad packaging with matching footprint dimensions (5.00mm x 5.00mm), maximum seated height (1.48mm), and thermal resistance (11°C/W). Moisture sensitivity level (2A, 4 Weeks) is identical for both parts.
