Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000BA4 is based on the following critical parameters:

Electrical Compatibility:

• Color and CCT matching (White, Neutral 4000K)
• CRI consistency (80 Typ)
• Viewing angle (120°)
• Package type (2-SMD, Gull Wing Exposed Pad)
• Physical dimensions (5.00 mm × 5.00 mm footprint)
• Thermal resistance (11°C/W)

Operational Considerations:

• The MX3SWT operates at 10.7V forward voltage with a 115 mA test current, delivering 97 lumens
• Substitute parts must maintain the same color temperature and CRI to ensure optical consistency in the application
• Physical and thermal characteristics must align to ensure drop-in compatibility in existing PCB designs

The MX3AWT-A1-0000-000CA4 is identified as a suitable substitute based on matching color, CCT, CRI, viewing angle, package configuration, and physical dimensions. However, electrical operating parameters differ significantly.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MX3SWT-A1-0000-000BA4 is obsolete. The MX3AWT-A1-0000-000CA4 is active and available, making it the primary substitute for ongoing production and replacement applications.

Compliance: The MX3AWT-A1-0000-000CA4 carries RoHS Compliant certification, whereas RoHS status is not specified for the main part. Both parts maintain REACH Unaffected status.

Optical and Mechanical Compatibility: Both parts share identical color temperature (4000K), CRI (80 Typ), viewing angle (120°), package configuration (2-SMD Gull Wing Exposed Pad), physical dimensions (5.00 mm × 5.00 mm), and thermal resistance (11°C/W). These parameters ensure optical consistency and mechanical drop-in compatibility.

Electrical Parameter Differences: The substitute part operates at significantly lower forward voltage (3.7V vs. 10.7V) and higher test current (350 mA vs. 115 mA). Circuit design modifications are required to accommodate these electrical differences. The substitute delivers higher luminous flux (104 lm vs. 97 lm) at comparable efficiency (80 lm/W vs. 79 lm/W).

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000CA4 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BA4?

A: The parts are mechanically and optically compatible due to identical package configuration, physical dimensions, color temperature, CRI, and viewing angle. However, electrical parameters differ substantially. The substitute requires circuit redesign to accommodate the lower forward voltage (3.7V vs. 10.7V) and higher operating current (350 mA vs. 115 mA). Direct PCB substitution without circuit modification is not possible.

Q: Are there any compliance differences between these parts?

A: The MX3AWT-A1-0000-000CA4 is certified RoHS Compliant, while RoHS status is not specified for the MX3SWT-A1-0000-000BA4. Both parts maintain REACH Unaffected status. If RoHS compliance is a requirement, the substitute part meets this criterion.

Q: What is the impact of the different forward voltages on system design?

A: The MX3SWT operates at 10.7V, while the MX3AWT operates at 3.7V. This 7V difference requires redesign of the LED driver circuit, current limiting resistors, and power supply configuration. The substitute's higher current requirement (350 mA vs. 115 mA) also impacts thermal management and power dissipation calculations.

Q: Do both parts have the same thermal characteristics?

A: Yes. Both parts have identical thermal resistance of 11°C/W and the same MSL rating of 2A (4 Weeks). Thermal management considerations remain consistent between the main part and substitute.

Q: Why is the MX3SWT-A1-0000-000BA4 classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The MX3AWT-A1-0000-000CA4, from the newer XLamp® MX-3 series, is the active replacement offering improved availability and ongoing manufacturer support.
