Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3SWT-A1-0000-0008B7 is determined by the following critical parameters:

• Color: White
• Mounting Type: Surface Mount
• Package / Case: 2-SMD, Gull Wing Exposed Pad
• Size / Dimension: 5.00mm x 5.00mm
• Height - Seated (Max): 1.48mm
• Thermal Resistance of Package: 11°C/W
• Viewing Angle: 120°

The identified substitute MX3AWT-A1-0000-0008B4 shares identical mechanical and thermal characteristics, including package type, footprint dimensions, height, and thermal resistance. Both components are CreeLED white LEDs with matching viewing angles and surface mount configurations. However, electrical parameters differ significantly: the substitute operates at 3.7V forward voltage with 350mA test current, compared to the main part's 10.7V and 115mA specifications.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-0008B4 is an active product from CreeLED with current manufacturing status, providing supply chain continuity for the obsolete MX3SWT-A1-0000-0008B7. Both components share identical mechanical footprints, thermal characteristics, and package configurations, enabling direct PCB layout compatibility.

The primary consideration for substitution is the significant difference in electrical operating parameters. The MX3AWT operates at 3.7V forward voltage with 350mA test current, whereas the MX3SWT operates at 10.7V with 115mA test current. Circuit designs must accommodate these electrical differences through appropriate driver and power supply modifications. Both components deliver equivalent luminous flux at their respective test currents (77lm nominal).

The MX3AWT-A1-0000-0008B4 is RoHS compliant, providing additional regulatory alignment for new designs. Both components maintain REACH unaffected status and identical moisture sensitivity levels.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0008B4 be used as a direct drop-in replacement for the MX3SWT-A1-0000-0008B7?

A: The components share identical mechanical and thermal characteristics, including package type, footprint, height, and thermal resistance. However, electrical parameters differ substantially. Direct PCB placement is compatible, but circuit design modifications are required to accommodate the different forward voltage (3.7V vs. 10.7V) and test current (350mA vs. 115mA) specifications.

Q: What are the key mechanical compatibility factors?

A: Both components use 2-SMD, Gull Wing Exposed Pad packaging with identical 5.00mm x 5.00mm footprints and 1.48mm maximum seated height. Thermal resistance is identical at 11°C/W. These parameters ensure PCB layout and thermal management compatibility.

Q: How do the electrical specifications differ?

A: The MX3SWT-A1-0000-0008B7 operates at 10.7V forward voltage with 115mA test current and 175mA maximum current. The MX3AWT-A1-0000-0008B4 operates at 3.7V forward voltage with 350mA test current and 500mA maximum current. Circuit designs must be modified to accommodate these differences.

Q: Are both components suitable for new designs?

A: The MX3SWT-A1-0000-0008B7 is classified as obsolete and unsuitable for new designs. The MX3AWT-A1-0000-0008B4 is active and recommended for new applications requiring white surface mount LEDs with 120° viewing angle and 5.00mm x 5.00mm package dimensions.

Q: What is the luminous output comparison?

A: Both components deliver 77lm nominal flux at their respective test currents. The MX3SWT achieves 63 lm/W efficiency, while the MX3AWT achieves 59 lm/W efficiency.
