Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000B50 is evaluated based on the following critical parameters:

• Color and CCT: Both parts must be White, Cool 6000K to maintain color consistency in the application
• Package and Mounting: Both parts must use 2-SMD, Gull Wing Exposed Pad surface mount configuration with identical 5.00mm x 5.00mm footprint and 1.48mm seated height to ensure PCB compatibility
• Viewing Angle: Both parts maintain 120° viewing angle for consistent optical performance
• Thermal Characteristics: Thermal resistance of 11°C/W is maintained across both parts
• Moisture Sensitivity: Both parts are classified as MSL 2A (4 Weeks)

The MX3AWT-A1-0000-000E50 qualifies as a substitute based on these core parameters. However, this substitute operates at significantly different electrical characteristics (3.7V forward voltage, 350mA test current versus 10.7V and 115mA), which requires circuit-level design evaluation and is not a direct pin-for-pin replacement in constant-current driver applications.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000E50 is the identified substitute for the obsolete MX3SWT-A1-0000-000B50. Selection of this substitute is supported by the following factors:

• Product Status: The MX3AWT-A1-0000-000E50 is Active, ensuring ongoing availability and supply chain support, whereas the main part is Obsolete
• Compliance: The MX3AWT-A1-0000-000E50 is RoHS Compliant, meeting current regulatory requirements
• Mechanical Compatibility: Identical package footprint (5.00mm x 5.00mm), mounting type (2-SMD Gull Wing Exposed Pad), and seated height (1.48mm) ensure PCB-level compatibility
• Optical Consistency: Both parts maintain 6000K cool white color temperature and 120° viewing angle
• Thermal Characteristics: Identical thermal resistance (11°C/W) and moisture sensitivity classification (MSL 2A)

The substitute part operates at lower forward voltage (3.7V versus 10.7V) and higher test current (350mA versus 115mA). Circuit design modifications to the LED driver are required to accommodate these electrical differences. The substitute delivers higher luminous flux (118 lm versus 97 lm) and improved efficiency (91 lm/W versus 79 lm/W) at its rated operating point.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000E50 be used as a direct replacement without circuit modifications?

A: No. While the MX3AWT-A1-0000-000E50 shares the same physical footprint and package configuration, it operates at significantly different electrical parameters. The forward voltage is 3.7V (versus 10.7V) and the test current is 350mA (versus 115mA). The LED driver circuit must be redesigned to supply the correct voltage and current for the substitute part.

Q: Are there any PCB layout considerations when switching to the MX3AWT-A1-0000-000E50?

A: The physical footprint remains identical (5.00mm x 5.00mm, 2-SMD Gull Wing Exposed Pad, 1.48mm seated height), so PCB layout and land pattern do not require modification. Thermal management and current path design may require evaluation based on the higher operating current (350mA versus 115mA).

Q: What is the difference between the XLamp® MX-3S and XLamp® MX-3 series?

A: The MX3SWT-A1-0000-000B50 belongs to the XLamp® MX-3S series, while the substitute MX3AWT-A1-0000-000E50 belongs to the XLamp® MX-3 series. Both are CreeLED products with identical package configurations and optical characteristics (6000K, 120° viewing angle, 75 CRI). The primary differences are electrical operating parameters and product status (Obsolete versus Active).

Q: Is the MX3AWT-A1-0000-000E50 RoHS compliant?

A: Yes. The MX3AWT-A1-0000-000E50 is RoHS Compliant. The main part (MX3SWT-A1-0000-000B50) does not specify RoHS status in the provided data.

Q: Will the substitute part provide equivalent brightness in my application?

A: The MX3AWT-A1-0000-000E50 delivers 118 lumens at its rated current (350mA) compared to 97 lumens for the main part at 115mA. Brightness equivalence depends on the actual operating current in your circuit design. The substitute offers higher efficiency (91 lm/W versus 79 lm/W), but circuit design determines the final light output.
