Key Parameters

Substitute Part Grouping Explanation

The MX3AWT-A1-0000-000BA5 qualifies as a substitute based on the following alignment of critical parameters:

Matching Parameters:

• Color and CCT: Both parts are White, Warm 3750K
• Flux Output: Both deliver 97 lm (94–100 lm range) at 25°C
• CRI: Both maintain 80 (Typ) Color Rendering Index
• Viewing Angle: Both provide 120° viewing angle
• Package / Case: Both use 2-SMD, Gull Wing Exposed Pad
• Physical Dimensions: Both measure 5.00mm x 5.00mm
• Height - Seated: Both maximum 1.48mm
• Thermal Resistance: Both 11°C/W
• Moisture Sensitivity Level: Both 2A (4 Weeks)
• REACH Status: Both REACH Unaffected

Differing Parameters (Design Consideration Required):

• Forward Voltage (Vf): MX3SWT operates at 10.7V; MX3AWT operates at 3.7V
• Test Current: MX3SWT at 115mA; MX3AWT at 350mA
• Maximum Current: MX3SWT at 175mA; MX3AWT at 500mA
• Lumens/Watt: MX3SWT at 79 lm/W; MX3AWT at 75 lm/W
• Series: MX3SWT is XLamp® MX-3S; MX3AWT is XLamp® MX-3
• Product Status: MX3SWT is Obsolete; MX3AWT is Active
• RoHS Status: MX3AWT is RoHS Compliant (MX3SWT status not provided)

Substitution is valid when the application can accommodate the lower forward voltage and higher current requirements of the MX3AWT, while maintaining the same luminous output and color characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000BA5 is the designated substitute for the obsolete MX3SWT-A1-0000-000BA5. Both parts maintain identical luminous output (97 lm), color temperature (3750K), and color rendering index (80 Typ), ensuring optical performance equivalence.

The primary design consideration is the electrical interface: the MX3AWT operates at 3.7V with a test current of 350mA, compared to the MX3SWT's 10.7V at 115mA. Circuit designs must be adapted to accommodate this lower voltage and higher current requirement. The maximum current rating increases from 175mA to 500mA, providing additional operational headroom.

The MX3AWT holds Active product status and RoHS Compliant certification, providing supply chain continuity and regulatory compliance advantages over the obsolete MX3SWT. Both parts share identical mechanical specifications (5.00mm x 5.00mm, 1.48mm height, 2-SMD Gull Wing Exposed Pad package) and thermal characteristics (11°C/W), ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BA5 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BA5?

A: The MX3AWT is mechanically and thermally compatible with the MX3SWT due to identical package dimensions and thermal resistance. However, the electrical interface differs significantly: the MX3AWT requires 3.7V at 350mA versus the MX3SWT's 10.7V at 115mA. Circuit redesign is necessary to accommodate this voltage and current change.

Q: Are the optical characteristics identical between these two parts?

A: Yes. Both parts deliver 97 lumens at 25°C, maintain 3750K color temperature, and provide 80 (Typ) CRI with 120° viewing angle. Optical performance is equivalent.

Q: What is the impact of the different forward voltage specifications?

A: The MX3AWT's lower forward voltage (3.7V vs. 10.7V) requires a different power supply or current-limiting circuit design. The higher test current (350mA vs. 115mA) necessitates appropriate current management and thermal considerations in the application circuit.

Q: Are both parts available in the same packaging format?

A: Both parts use 2-SMD, Gull Wing Exposed Pad packages with identical 5.00mm x 5.00mm dimensions and 1.48mm maximum seated height. The MX3AWT is supplied in Tape & Reel (TR) format, while the MX3SWT packaging format is not specified in the provided data.

Q: What is the regulatory compliance status of each part?

A: Both parts are REACH Unaffected. The MX3AWT is RoHS Compliant; the MX3SWT compliance status is not specified. The MX3AWT's Active product status ensures ongoing manufacturer support and supply availability.
