Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AF7 is evaluated based on the following critical parameters:

Electrical Compatibility Criteria:

• Color and CCT (Correlated Color Temperature): Both parts must match at 3200K warm white to maintain color consistency in lighting applications
• CRI (Color Rendering Index): Both parts maintain 80 (Typ), ensuring equivalent color rendering performance
• Viewing Angle: Both parts provide 120° viewing angle for consistent light distribution

Mechanical & Package Compatibility:

• Package Type: Both use 2-SMD, Gull Wing Exposed Pad configuration
• Physical Dimensions: Both measure 5.00mm × 5.00mm with 1.48mm maximum seated height
• Mounting Type: Both are surface mount compatible with identical footprints
• Thermal Resistance: Both maintain 11°C/W thermal performance

Environmental & Regulatory Compliance:

• Moisture Sensitivity Level: Both rated 2A (4 Weeks)
• REACH Status: Both are REACH Unaffected
• ECCN Classification: Both classified as EAR99

The MX3AWT-A1-0000-000BF7 qualifies as a functional substitute based on matching color temperature, CRI, viewing angle, package geometry, and regulatory compliance. However, electrical operating parameters differ significantly and must be evaluated for circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MX3SWT-A1-0000-000AF7 is classified as Obsolete, making the MX3AWT-A1-0000-000BF7 a necessary alternative for ongoing procurement. The substitute part carries Active product status, ensuring continued availability and manufacturer support.

Compliance & Certification: Both parts maintain identical REACH and MSL classifications. The MX3AWT-A1-0000-000BF7 provides additional RoHS Compliance certification, meeting stricter environmental standards for regulated markets.

Electrical Parameter Differences: The substitute part operates at significantly lower forward voltage (3.7V vs. 10.7V) and higher test current (350mA vs. 115mA). Circuit design modifications are required to accommodate these electrical differences. The substitute delivers higher luminous flux (97 lm vs. 91 lm) at its rated current, with comparable lumens/watt efficiency (75 vs. 74 lm/W).

Mechanical & Optical Compatibility: Package geometry, thermal characteristics, viewing angle, and color rendering properties are identical between both parts, enabling direct footprint compatibility in PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BF7 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AF7?

A: Mechanical and optical compatibility is direct—both parts use identical 5.00mm × 5.00mm 2-SMD packages with 120° viewing angle and 3200K color temperature. However, electrical circuit redesign is mandatory. The substitute operates at 3.7V forward voltage versus 10.7V, requiring modification of current-limiting resistors and power supply specifications.

Q: What are the key substitution criteria for warm white 3200K XLamp LEDs?

A: Substitution is valid when parts match on color temperature (3200K), CRI (80 Typ), viewing angle (120°), package type (2-SMD Gull Wing), physical dimensions (5.00mm × 5.00mm), and thermal resistance (11°C/W). Electrical parameters (voltage and current) must be evaluated separately for circuit compatibility.

Q: Does the MX3AWT-A1-0000-000BF7 provide better performance than the obsolete MX3SWT-A1-0000-000AF7?

A: The substitute delivers higher luminous flux (97 lm vs. 91 lm) and maintains equivalent lumens/watt efficiency (75 vs. 74 lm/W). Both parts provide identical color rendering (CRI 80) and viewing characteristics. Performance improvement is marginal; the primary advantage is Active product status and continued availability.

Q: Are there environmental or regulatory differences between these parts?

A: Both parts are REACH Unaffected and maintain MSL 2A (4 Weeks) moisture sensitivity. The MX3AWT-A1-0000-000BF7 carries RoHS Compliance certification, providing additional environmental compliance for regulated applications. The main part's RoHS status is not specified.

Q: What circuit modifications are necessary when substituting the MX3AWT-A1-0000-000BF7 for the MX3SWT-A1-0000-000AF7?

A: Forward voltage reduction from 10.7V to 3.7V requires recalculation of series current-limiting resistors. Test current increases from 115mA to 350mA, necessitating power supply capacity review and thermal management assessment. Maximum current ratings differ (175mA vs. 500mA), affecting overcurrent protection settings.

Q: Is the package footprint identical between both parts?

A: Yes. Both parts use 2-SMD, Gull Wing Exposed Pad configuration with 5.00mm × 5.00mm dimensions and 1.48mm maximum seated height. PCB footprints are directly compatible without modification.
