Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000CB1 is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 2-SMD, Gull Wing Exposed Pad
• Physical dimensions: 5.00mm × 5.00mm footprint
• Height: 1.48mm maximum seated height
• Mounting type: Surface Mount

Electrical Compatibility:

• Color: White
• Viewing angle: 120°
• Thermal resistance: 11°C/W

Operational Parameters:

• Forward voltage (Vf): Determines circuit design and driver requirements
• Test current and maximum current ratings: Define safe operating range
• Luminous flux output: Determines brightness performance
• Lumens per watt efficiency: Indicates power conversion efficiency

The identified substitute MX3AWT-A1-0000-000DB1 shares identical mechanical specifications and viewing angle, enabling direct footprint compatibility. However, this substitute operates at significantly different electrical parameters (3.7V forward voltage versus 10.7V, and 350mA test current versus 115mA), requiring circuit redesign and driver reconfiguration.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000DB1 provides mechanical and optical compatibility with the obsolete MX3SWT-A1-0000-000CB1 through identical package geometry, footprint dimensions, and 120° viewing angle. Both components maintain equivalent thermal resistance and moisture sensitivity specifications.

The primary distinction lies in electrical operation. The MX3AWT operates at 3.7V forward voltage with 350mA test current, compared to the MX3SWT's 10.7V and 115mA specifications. This represents a fundamental shift in power delivery architecture and requires complete redesign of the LED driver circuit and power supply topology.

The MX3AWT-A1-0000-000DB1 holds active product status with RoHS compliance certification, whereas the MX3SWT is classified as obsolete. Both components maintain identical REACH and ECCN classifications, ensuring equivalent regulatory standing for export and compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000DB1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000CB1?

A: No. While both components share identical mechanical specifications and can occupy the same PCB footprint, the MX3AWT operates at fundamentally different electrical parameters. The MX3AWT requires 3.7V forward voltage and 350mA test current, whereas the MX3SWT requires 10.7V and 115mA. Circuit redesign is mandatory.

Q: What are the key mechanical compatibility factors?

A: Both parts feature 2-SMD Gull Wing Exposed Pad packaging with 5.00mm × 5.00mm footprint dimensions and 1.48mm maximum seated height. PCB layout and reflow profiles remain compatible. Thermal management characteristics are identical at 11°C/W.

Q: How do the luminous outputs compare?

A: The MX3AWT delivers 111 lumens at 25°C under its 350mA test current, compared to 104 lumens for the MX3SWT at 115mA test current. Both achieve approximately 85-86 lumens per watt efficiency. Brightness performance is comparable despite different operating currents.

Q: What is the significance of product status differences?

A: The MX3SWT is obsolete and no longer manufactured. The MX3AWT is active production, ensuring long-term availability and supply chain stability. For new designs or production continuity, the active MX3AWT is the appropriate selection.

Q: Are there compliance or regulatory differences?

A: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99). The MX3AWT includes RoHS compliance certification. Moisture sensitivity levels are equivalent at 2A (4 Weeks).
