Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3SWT-A1-0000-000AB4 is determined by the following critical parameters:

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

Optical Compatibility: Color (White) and viewing angle (120°) must remain constant for optical performance consistency.

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

Regulatory Compliance: REACH Status and ECCN classification must be maintained.

The MX3AWT-A1-0000-000AB4 meets these mechanical, optical, thermal, and regulatory criteria. However, this substitute operates at significantly different electrical parameters (3.7V forward voltage, 350mA test current) compared to the main part (10.7V, 115mA), requiring circuit redesign for voltage and current compatibility.

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AB4 is the identified substitute for the obsolete MX3SWT-A1-0000-000AB4. Selection of this substitute is supported by:

Product Status: The substitute is classified as Active, ensuring ongoing availability and manufacturing support, whereas the main part is Obsolete.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification, satisfying export and environmental compliance requirements.

Mechanical and Optical Compatibility: Identical package type, physical dimensions, height, thermal resistance, and viewing angle enable direct PCB footprint compatibility and optical performance consistency.

Electrical Redesign Requirement: The substitute operates at 3.7V forward voltage and 350mA test current, compared to the main part's 10.7V and 115mA. Circuit redesign of the LED driver and power supply is necessary to accommodate these electrical differences. The substitute's maximum current rating of 500mA versus the main part's 175mA also requires current-limiting circuit adjustment.

Luminous Output: Both parts deliver 91 lumens at their respective test currents, maintaining equivalent brightness performance.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000AB4 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AB4?

A: No. While both parts share identical mechanical packaging, physical dimensions, and thermal characteristics, they operate at fundamentally different electrical parameters. The substitute requires 3.7V forward voltage and 350mA test current, whereas the main part requires 10.7V and 115mA. Direct substitution without circuit redesign will result in component failure or malfunction.

Q: What circuit modifications are required to use the MX3AWT-A1-0000-000AB4?

A: The LED driver and power supply must be redesigned to deliver 3.7V at up to 500mA maximum current to the substitute part. The main part's 10.7V, 175mA maximum current specifications are not compatible with the substitute's electrical requirements.

Q: Are the optical characteristics identical between these parts?

A: Yes. Both parts are White LEDs with 120° viewing angle and deliver 91 lumens at their respective test currents. Optical performance and color output are equivalent.

Q: What is the significance of the product status difference?

A: The main part (MX3SWT-A1-0000-000AB4) is Obsolete, indicating discontinued manufacturing and limited availability. The substitute (MX3AWT-A1-0000-000AB4) is Active, ensuring continued production, technical support, and long-term supply chain reliability.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts maintain REACH Unaffected status and EAR99 ECCN classification, satisfying environmental and export compliance requirements.

Q: Are the thermal management characteristics the same?

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