Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000CB2 is based on the following critical parameters that define functional and mechanical compatibility:

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

Optical Compatibility: Viewing angle of 120° is maintained across substitute parts to preserve beam pattern characteristics.

Thermal Compatibility: Thermal resistance of 11°C/W must be matched to ensure equivalent thermal performance in the application circuit.

Regulatory Compliance: REACH status and ECCN classification must align with the original part to maintain supply chain and export compliance.

Electrical Substitution Criteria: While forward voltage and test current differ between the main part and substitute, substitutes must operate within the same general application class (white LED lighting) and maintain compatible mounting and package specifications. The substitute part MX3AWT-A1-0000-000DB1 shares identical mechanical, thermal, and optical parameters, making it a valid substitute despite different electrical operating points.

Engineering Selection Recommendations

The MX3AWT-A1-0000-000DB1 is the designated substitute for the obsolete MX3SWT-A1-0000-000CB2. This substitution is supported by:

Product Status: The MX3AWT-A1-0000-000DB1 maintains Active product status, ensuring continued availability and supply chain support, whereas the original part is classified as Obsolete.

Regulatory Compliance: Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification, preserving compliance requirements across supply chain and export regulations.

Mechanical and Thermal Equivalence: Identical package type, physical dimensions, height, and thermal resistance ensure direct PCB assembly compatibility without design modification or thermal performance degradation.

Optical Performance: Both parts maintain 120° viewing angle, preserving beam pattern characteristics in the application.

Electrical Differences: The substitute operates at 3.7V forward voltage with 350mA test current, compared to 10.7V and 115mA for the original part. Circuit design modifications are required to accommodate these electrical differences. Luminous flux output is comparable (111lm versus 104lm at respective test currents), and efficiency is equivalent (86 lm/W versus 85 lm/W).

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000DB1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000CB2?

A: The MX3AWT-A1-0000-000DB1 is mechanically and thermally compatible for PCB assembly without modification. However, the significant difference in forward voltage (3.7V versus 10.7V) and test current (350mA versus 115mA) requires circuit redesign. The substitute cannot be used without modifying the power supply and current-limiting circuitry.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical package specifications (2-SMD, Gull Wing Exposed Pad), physical dimensions (5.00mm x 5.00mm), and maximum seated height (1.48mm). These parameters ensure compatibility with existing PCB layouts and assembly processes.

Q: Are there differences in thermal performance?

A: Both parts have identical thermal resistance of 11°C/W, ensuring equivalent thermal management characteristics in the application circuit.

Q: What regulatory compliance considerations apply?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. No changes to regulatory compliance documentation are required for this substitution.

Q: How do the optical characteristics compare?

A: Both parts maintain 120° viewing angle. Luminous flux at respective test currents is comparable (104lm for the original at 115mA; 111lm for the substitute at 350mA), with equivalent efficiency ratings (85 lm/W and 86 lm/W respectively).

Q: What is the primary reason for substitution?

A: The original MX3SWT-A1-0000-000CB2 is classified as Obsolete. The MX3AWT-A1-0000-000DB1 is an Active product with continued manufacturer support and supply availability.
