Substitute Part Grouping Explanation

The MX3AWT-A1-0000-000AB3 is identified as a substitute for the MX3SWT-A1-0000-000AB3 based on the following criteria:

Mechanical Compatibility:

• Identical package type: 2-SMD, Gull Wing Exposed Pad
• Identical footprint dimensions: 5.00mm x 5.00mm
• Identical maximum seated height: 1.48mm
• Identical thermal resistance: 11°C/W
• Identical viewing angle: 120°

Electrical Compatibility:

• Identical color: White
• Identical luminous flux output: 91lm (87lm ~ 94lm) at test current
• Identical moisture sensitivity level: 2A (4 Weeks)

Key Differences: The substitute operates at different electrical parameters: 3.7V forward voltage and 350mA test current versus the original 10.7V and 115mA. This represents a different operating point within the XLamp® family but maintains identical physical form factor and light output specifications.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AB3 is available as an active product with RoHS compliance certification, whereas the MX3SWT-A1-0000-000AB3 is obsolete. Both parts share identical mechanical specifications and light output characteristics, enabling direct footprint compatibility.

Selection of the substitute requires circuit redesign to accommodate the different forward voltage (3.7V versus 10.7V) and test current (350mA versus 115mA). The substitute maintains equivalent luminous flux output and viewing angle, supporting applications where light output and beam pattern are primary design constraints.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000AB3 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AB3?

A: The parts are mechanically compatible due to identical package dimensions, footprint, and height specifications. However, electrical circuit modifications are required because the substitute operates at 3.7V/350mA versus the original 10.7V/115mA. Direct soldering without circuit redesign will result in component failure.

Q: Are the light output specifications identical between these parts?

A: Both parts deliver 91 lumens (87lm ~ 94lm range) at their respective test currents. The luminous flux output is equivalent, though efficiency differs slightly: 74 lm/W for the MX3SWT versus 70 lm/W for the MX3AWT.

Q: What is the significance of the product status difference?

A: The MX3SWT-A1-0000-000AB3 is classified as obsolete, indicating discontinued manufacturing and limited availability. The MX3AWT-A1-0000-000AB3 is active and maintains ongoing production support with RoHS compliance certification.

Q: Are the viewing angles the same?

A: Both parts feature a 120° viewing angle, ensuring identical beam pattern characteristics for optical design purposes.

Q: What are the thermal characteristics?

A: Both parts have identical thermal resistance of 11°C/W, supporting equivalent thermal management in PCB layout and design.

Q: Is moisture sensitivity the same for both parts?

A: Both parts are classified as MSL 2A (4 Weeks), requiring identical moisture control and storage procedures during manufacturing and assembly.
