Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-000BA7 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Color and CCT: White, Warm 3250K (identical spectral output required)
• Viewing Angle: 120° (optical performance specification)
• Package / Case: 2-SMD, Gull Wing form factor (PCB footprint compatibility)
• Size / Dimension: 5.00 mm × 5.00 mm (mechanical fit)
• Height - Seated (Max): 1.48 mm (clearance requirement)
• Mounting Type: Surface Mount (assembly process compatibility)
• MSL: 2A (4 Weeks) (moisture handling during storage and assembly)

Electrical Parameters (Allowable Variance):

• Forward Voltage (Vf): May differ based on circuit design requirements
• Test Current: May differ based on application operating point
• Maximum Current: May differ based on thermal management capability
• Lumens/Watt: May differ based on efficiency requirements
• CRI: 80 (Typical) or higher acceptable for color rendering consistency

The substitute MX6AWT-A1-0000-000BA7 meets all mandatory matching criteria while offering improved electrical characteristics and active product status.

Engineering Selection Recommendations

The MX6AWT-A1-0000-000BA7 is the designated substitute for the obsolete MX6SWT-A1-0000-000BA7. Selection is based on the following engineering factors:

Product Status: The main part is classified as obsolete, while the substitute maintains active product status with ongoing manufacturer support and availability.

Compliance & Certifications: The substitute carries RoHS Compliance certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status and identical MSL ratings.

Optical & Thermal Equivalence: Both parts deliver identical luminous flux (97 lm) at 25°C, maintain the same 3250K warm white color temperature, CRI of 80, and 120° viewing angle. Thermal resistance is identical at 5°C/W.

Mechanical Compatibility: Both parts share identical footprint dimensions (5.00 mm × 5.00 mm) and seated height (1.48 mm), ensuring direct PCB layout compatibility. The substitute features an exposed pad variant of the 2-SMD Gull Wing package, which enhances thermal dissipation capability.

Electrical Differences: The substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA. This represents a fundamental circuit architecture difference. Circuit redesign is required to accommodate the substitute's lower voltage and higher current operating point. The substitute achieves superior efficiency at 98 lm/W versus 81 lm/W.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000BA7 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000BA7?

A: The parts are mechanically and optically compatible (identical footprint, height, color, and luminous flux). However, electrical redesign is mandatory. The substitute requires a 3.3V supply at 300mA instead of 20V at 60mA. Existing power supply and current-limiting circuits must be modified to accommodate these specifications.

Q: Are the color and brightness characteristics identical between the two parts?

A: Yes. Both parts deliver 97 lumens at 25°C, maintain 3250K warm white color temperature, and provide 80 CRI. Optical performance is equivalent for lighting applications.

Q: What is the significance of the exposed pad in the substitute part's package?

A: The exposed pad in the 2-SMD Gull Wing Exposed Pad package provides enhanced thermal dissipation compared to standard Gull Wing packages. This improves heat transfer from the LED junction to the PCB, supporting higher current operation and improved thermal management.

Q: Does the substitute part require different PCB layout considerations?

A: PCB footprint dimensions remain identical (5.00 mm × 5.00 mm). The exposed pad variant may benefit from thermal vias connected to a ground or thermal plane for optimal heat dissipation, though this is not mandatory for basic functionality.

Q: Is the substitute part RoHS compliant?

A: Yes. The MX6AWT-A1-0000-000BA7 carries RoHS Compliance certification. The main part does not specify RoHS status. Both parts maintain REACH Unaffected status.

Q: What is the moisture sensitivity level, and how does it affect handling?

A: Both parts carry MSL 2A (4 Weeks) rating. This requires storage in controlled humidity environments and limits the time between package opening and soldering to 4 weeks under specified conditions. Standard moisture-barrier packaging and desiccant handling apply.

Q: Can I use the substitute in existing designs without circuit modification?

A: No. The substitute's 3.3V forward voltage and 300mA test current differ fundamentally from the main part's 20V and 60mA specifications. Power supply, current-limiting resistors or drivers, and thermal management must be redesigned for the substitute's electrical characteristics.
