Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-0009E6 is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Color and CCT match (White, Warm 3500K)
• CRI equivalence (80 Typ)
• Viewing angle compatibility (120°)
• Package type and mechanical dimensions (2-SMD, Gull Wing Exposed Pad; 5.00 mm × 5.00 mm; 1.48 mm height)
• Thermal resistance (11°C/W)
• Moisture sensitivity level (2A, 4 Weeks)
• REACH compliance status

Secondary Considerations:

• Electrical parameters (forward voltage, test current, maximum current) may differ between series generations
• Lumens/Watt efficiency may vary
• Product status (active vs. obsolete) affects long-term availability

The MX3AWT-A1-0000-0009E6 qualifies as a substitute based on matching color, CCT, CRI, viewing angle, package dimensions, thermal characteristics, and compliance certifications. However, electrical operating parameters differ significantly due to series generation differences.

Engineering Selection Recommendations

For MX3AWT-A1-0000-0009E6 Substitution:

The MX3AWT-A1-0000-0009E6 is suitable as a substitute where the following conditions are met:

1. Optical and Thermal Compatibility: Identical color temperature (3500K), CRI (80), viewing angle (120°), and thermal resistance (11°C/W) ensure optical and thermal performance equivalence.

2. Mechanical Compatibility: Identical package type, dimensions (5.00 mm × 5.00 mm), and height (1.48 mm) confirm direct PCB footprint compatibility.

3. Compliance and Reliability: Both parts maintain REACH Unaffected status and 2A MSL rating. The substitute offers RoHS Compliance, providing enhanced regulatory alignment for new designs.

4. Electrical Parameter Differences: The substitute operates at significantly lower forward voltage (3.7V vs. 10.7V) and higher test current (350 mA vs. 115 mA). Circuit design modifications are required to accommodate these electrical differences. Power supply and current-limiting circuitry must be re-evaluated.

5. Product Status Advantage: The substitute's Active status ensures long-term availability and supply chain continuity, addressing the obsolescence of the main part.

Selection Criteria:

• Use the substitute when circuit design can accommodate the lower forward voltage and higher current requirements.
• Verify thermal management capability for the higher operating current.
• Confirm power supply compatibility with the revised electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0009E6 be used as a direct drop-in replacement for the MX3SWT-A1-0000-0009E6?

A: No. While both parts share identical optical characteristics (color, CCT, CRI, viewing angle) and mechanical dimensions (package, size, height), the electrical parameters differ significantly. The substitute requires a forward voltage of 3.7V compared to 10.7V for the main part, and operates at 350 mA test current versus 115 mA. Circuit redesign is necessary.

Q: Are the package dimensions identical between the two parts?

A: Yes. Both parts use a 2-SMD, Gull Wing Exposed Pad package with dimensions of 5.00 mm × 5.00 mm and a seated height of 1.48 mm. PCB footprints are mechanically compatible.

Q: What is the impact of the lower forward voltage on circuit design?

A: The substitute's 3.7V forward voltage requires a lower supply voltage or modified current-limiting circuitry compared to the main part's 10.7V requirement. Power dissipation and thermal management calculations must be recalculated based on the new voltage and current specifications.

Q: Does the substitute offer better compliance or regulatory status?

A: Yes. The MX3AWT-A1-0000-0009E6 is RoHS Compliant, whereas RoHS status is not specified for the main part. Both maintain REACH Unaffected status. The substitute's Active product status also ensures ongoing availability.

Q: Are the thermal characteristics equivalent?

A: Yes. Both parts have identical thermal resistance of 11°C/W. However, the higher operating current of the substitute (350 mA vs. 115 mA) results in higher absolute power dissipation, requiring verification of thermal management in the application.

Q: What is the MSL rating, and does it differ between the parts?

A: Both parts carry an MSL rating of 2A (4 Weeks), indicating identical moisture sensitivity and storage requirements.
