Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-0008F6 is based on the following critical parameters:

Matching Criteria:

• Color and CCT: White, Warm 3750K (identical)
• CRI: 80 (Typ) (identical)
• Viewing Angle: 120° (identical)
• Package / Case: 2-SMD, Gull Wing Exposed Pad (identical)
• Physical Dimensions: 5.00mm x 5.00mm (identical)
• Height - Seated: 1.48mm (identical)
• Thermal Resistance: 11°C/W (identical)
• Mounting Type: Surface Mount (identical)
• MSL Rating: 2A (4 Weeks) (identical)

Differing Parameters (Design Consideration):

• Forward Voltage (Vf): MX3SWT operates at 10.7V; substitute MX3AWT operates at 3.7V
• Test Current: MX3SWT at 115mA; substitute MX3AWT at 350mA
• Maximum Current: MX3SWT at 175mA; substitute MX3AWT at 500mA
• Lumens/Watt: MX3SWT at 63 lm/W; substitute MX3AWT at 59 lm/W
• Product Status: MX3SWT is Obsolete; substitute MX3AWT is Active

The MX3AWT-A1-0000-0008A5 represents the active production equivalent within the XLamp® warm white 3750K product line, maintaining identical optical and mechanical characteristics while operating at significantly lower voltage and higher current levels.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-0008A5 is the active production substitute for the obsolete MX3SWT-A1-0000-0008F6. Both parts maintain identical optical output (77lm at 3750K, CRI 80), mechanical form factor (5.00mm x 5.00mm, 2-SMD package), and thermal characteristics (11°C/W).

The primary design consideration is the voltage and current operating point. The MX3AWT operates at 3.7V typical forward voltage with 350mA test current, compared to the MX3SWT's 10.7V and 115mA. This represents a fundamental shift in the LED architecture between the MX-3S and MX-3 series. Circuit designs must be re-evaluated to accommodate the lower voltage and higher current requirements of the substitute part.

The MX3AWT-A1-0000-0008A5 carries RoHS Compliant certification and is supplied in Tape & Reel packaging, supporting modern manufacturing and environmental compliance requirements. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0008A5 be used as a direct drop-in replacement for the MX3SWT-A1-0000-0008F6?

A: No. While both parts share identical optical output, color temperature, CRI, viewing angle, and mechanical dimensions, the forward voltage differs significantly (3.7V vs. 10.7V). The circuit design, current limiting, and power supply must be re-evaluated for the substitute part's lower voltage and higher current operating point.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both parts are 5.00mm x 5.00mm with 1.48mm seated height in a 2-SMD, Gull Wing Exposed Pad package. PCB footprints and mechanical assembly are compatible.

Q: What is the difference in luminous output between these parts?

A: Both parts deliver 77lm (74lm – 81lm) at their respective test currents. The MX3SWT achieves 63 lm/W efficiency, while the MX3AWT achieves 59 lm/W. The absolute light output is equivalent.

Q: Why is the MX3SWT-A1-0000-0008F6 obsolete?

A: The XLamp® MX-3S series has been superseded by the XLamp® MX-3 series. CreeLED has transitioned production to the newer MX-3 architecture, which offers improved manufacturing efficiency and supply chain optimization.

Q: Is the substitute part RoHS compliant?

A: Yes. The MX3AWT-A1-0000-0008A5 is RoHS Compliant. The main part status is not specified in available documentation.

Q: What packaging options are available for the substitute part?

A: The MX3AWT-A1-0000-0008A5 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
