Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000BA8 is based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Criteria:

• Color and Correlated Color Temperature (CCT): White, Warm 3000K
• Viewing Angle: 120°
• Package Type: 2-SMD, Gull Wing Exposed Pad
• Physical Dimensions: 5.00 mm × 5.00 mm footprint
• Mounting Type: Surface Mount
• CRI: 80 (Typ)

Allowable Variation Parameters:

• Forward Voltage (Vf): May differ based on circuit design requirements
• Test Current and Maximum Current: May vary with different LED generations
• Lumens/Watt efficiency: Expected to improve in newer generations
• Thermal Resistance: May improve in newer designs
• Product Status: Active status preferred for ongoing availability

The MX6AWT-A1-0000-000BA8 qualifies as a substitute because it maintains identical color temperature, viewing angle, package configuration, and physical footprint while offering improved electrical efficiency and active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The MX3SWT-A1-0000-000BA8 is classified as obsolete. The MX6AWT-A1-0000-000BA8 carries active product status, ensuring continued availability, manufacturing support, and compliance with current regulatory standards.

Compliance and Certifications

The MX6AWT-A1-0000-000BA8 is RoHS Compliant, whereas RoHS status is not specified for the MX3SWT-A1-0000-000BA8. Both parts maintain REACH Unaffected status and identical MSL ratings (2A, 4 Weeks).

Electrical Design Considerations

The substitute part operates at significantly lower forward voltage (3.3V vs. 10.7V) and higher test current (300 mA vs. 115 mA). Circuit designs must be re-evaluated to accommodate these electrical differences. The MX6AWT-A1-0000-000BA8 delivers improved thermal performance (5°C/W vs. 11°C/W) and higher luminous efficacy (98 lm/W vs. 79 lm/W).

Mechanical Compatibility

Both parts share identical package configuration, footprint dimensions (5.00 mm × 5.00 mm), and maximum seated height (1.48 mm), ensuring PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000BA8 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BA8?

A: Mechanical compatibility is confirmed—both parts use identical 2-SMD Gull Wing Exposed Pad packages with 5.00 mm × 5.00 mm footprints. However, electrical circuit redesign is required due to the significant difference in forward voltage (10.7V vs. 3.3V) and test current (115 mA vs. 300 mA). PCB layout remains compatible without modification.

Q: Why does the substitute part have lower forward voltage?

A: The MX6AWT-A1-0000-000BA8 represents a newer generation within the XLamp product line. Advances in LED die technology and packaging have reduced forward voltage while maintaining equivalent luminous output and color characteristics.

Q: Are the color and brightness specifications identical?

A: Yes. Both parts deliver 97 lm at 3000K (warm white) with 80 CRI and 120° viewing angle. The substitute achieves this output at higher efficiency (98 lm/W vs. 79 lm/W).

Q: What is the impact of improved thermal resistance in the substitute part?

A: The MX6AWT-A1-0000-000BA8 features superior thermal resistance (5°C/W vs. 11°C/W), enabling better heat dissipation from the LED junction. This reduces operating temperature and extends component lifespan under identical thermal management conditions.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts carry MSL 2A (4 Weeks) ratings, requiring identical moisture control procedures during storage, handling, and assembly.

Q: Does the substitute part meet current regulatory compliance?

A: The MX6AWT-A1-0000-000BA8 is RoHS Compliant and maintains REACH Unaffected status. Both parts carry active or unaffected regulatory standing, suitable for current production environments.
