Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000AA7 is evaluated based on the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must deliver warm white light at 3250K to maintain consistent color output in lighting applications.

Photometric Output: Luminous flux at 25°C must remain within the specified range (87–94 lm) to ensure equivalent brightness performance.

Color Rendering Index (CRI): A CRI of 80 (typical) is required to maintain color fidelity in warm white applications.

Package and Mounting: Both components must use the 2-SMD, Gull Wing Exposed Pad configuration with 5.00 mm × 5.00 mm footprint and 1.48 mm maximum seated height to ensure PCB compatibility and thermal management through the exposed pad.

Viewing Angle: A 120° viewing angle is specified for both components to maintain consistent light distribution characteristics.

Thermal and Environmental Compliance: Thermal resistance of 11°C/W, MSL 2A rating, REACH Unaffected status, and ECCN EAR99 classification must be maintained.

The substitute part MX3AWT-A1-0000-000AA7 meets these substitution criteria. However, this substitute operates at significantly different electrical parameters: 3.7V forward voltage and 350mA test current, compared to the main part's 10.7V and 115mA. These differences require circuit-level design verification to ensure compatibility with existing power supply and current-limiting configurations.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AA7 is the identified substitute for the obsolete MX3SWT-A1-0000-000AA7. This substitute is classified as Active product status, ensuring ongoing availability and supply chain support.

Both components share identical photometric output (91 lm at 3250K), color rendering index (80 typical), package configuration (2-SMD, Gull Wing Exposed Pad, 5.00 mm × 5.00 mm), and thermal characteristics (11°C/W). Both maintain REACH Unaffected status and EAR99 ECCN classification.

The substitute part carries RoHS Compliant certification, whereas RoHS status is not specified for the main part.

The critical difference between these components is electrical: the substitute operates at 3.7V forward voltage with 350mA test current, compared to the main part's 10.7V and 115mA. This represents a fundamental change in the LED's internal architecture and power delivery requirements. Direct pin-for-pin substitution is not possible without circuit redesign. Power supply voltage, current-limiting resistor or driver circuit, and thermal management must be re-evaluated for the substitute part to ensure safe operation and compliance with the LED's maximum current rating of 500mA.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000AA7 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AA7?

A: No. While both components deliver identical luminous flux (91 lm) and color temperature (3250K), they operate at fundamentally different electrical parameters. The substitute requires 3.7V forward voltage at 350mA test current, whereas the main part requires 10.7V at 115mA. Direct substitution without circuit modification will result in incorrect LED operation or component failure.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by color temperature (3250K warm white), luminous flux range (87–94 lm at 25°C), color rendering index (80 typical), package configuration (2-SMD, Gull Wing Exposed Pad, 5.00 mm × 5.00 mm), viewing angle (120°), thermal resistance (11°C/W), and environmental compliance (REACH Unaffected, EAR99 ECCN, MSL 2A).

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both components share identical footprint dimensions (5.00 mm × 5.00 mm) and maximum seated height (1.48 mm). PCB layout and mechanical assembly compatibility are maintained. However, electrical circuit redesign is required.

Q: What is the product status difference, and why does it matter?

A: The main part (MX3SWT-A1-0000-000AA7) is classified as Obsolete, indicating it is no longer manufactured or supported. The substitute (MX3AWT-A1-0000-000AA7) is classified as Active, ensuring continued availability, technical support, and supply chain reliability for new designs or production continuity.

Q: Does the substitute part meet RoHS compliance?

A: Yes. The MX3AWT-A1-0000-000AA7 is RoHS Compliant. RoHS status is not specified for the main part.

Q: What thermal management considerations apply to both components?

A: Both components feature identical thermal resistance of 11°C/W and utilize an exposed pad for direct thermal coupling to the PCB. Thermal design and heat dissipation calculations remain consistent between the two parts. However, the substitute's higher test current (350mA vs. 115mA) may result in increased power dissipation under equivalent operating conditions, requiring thermal analysis specific to the substitute's electrical parameters.
