Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-0008B6 is based on the following critical parameters that must align for functional equivalence:

Mechanical Compatibility: Package type (2-SMD, Gull Wing Exposed Pad), physical dimensions (5.00mm x 5.00mm), and height (1.48mm maximum) must remain identical to ensure PCB layout and assembly compatibility.

Optical Characteristics: Color (white) and viewing angle (120°) must be preserved for application-specific light distribution requirements.

Thermal Properties: Thermal resistance of 11°C/W must be maintained to ensure equivalent thermal management in the application circuit.

Electrical Operating Range: Forward voltage and current ratings determine circuit design feasibility. Substitute parts must operate within the application's power supply and current-limiting constraints.

The MX3AWT-A1-0000-0008B4 is identified as a substitute based on matching mechanical package, optical properties, and thermal characteristics. However, significant differences exist in electrical parameters (forward voltage and test current), requiring circuit redesign evaluation.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-0008B4 provides mechanical and optical compatibility with the obsolete MX3SWT-A1-0000-0008B6. Both components share identical package geometry, thermal resistance, viewing angle, and color specification, enabling direct PCB footprint compatibility.

The MX3AWT-A1-0000-0008B4 holds Active product status, ensuring ongoing availability and supply chain continuity compared to the Obsolete MX3SWT-A1-0000-0008B6. The substitute part is RoHS Compliant, meeting environmental regulatory requirements.

Critical consideration: The MX3AWT-A1-0000-0008B4 operates at 3.7V forward voltage with 350mA test current, compared to the main part's 10.7V and 115mA specifications. This represents a fundamental shift in electrical operating parameters. Applications designed for the MX3SWT-A1-0000-0008B6 require circuit redesign to accommodate the lower forward voltage and higher current requirements of the MX3AWT-A1-0000-0008B4. Power supply voltage, current-limiting resistor values, and thermal management must be re-evaluated for the substitute configuration.

Both components maintain identical luminous flux output (77lm) at their respective test currents, though efficiency differs (63 lm/W versus 59 lm/W).

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0008B4 be used as a direct drop-in replacement for the MX3SWT-A1-0000-0008B6?

A: Mechanically and optically, yes. The components share identical package type, dimensions, height, thermal resistance, color, and viewing angle. However, electrical circuit redesign is required due to the significant difference in forward voltage (10.7V versus 3.7V) and test current (115mA versus 350mA). Direct substitution without circuit modification will result in component failure or inadequate performance.

Q: What are the key parameters that determine substitution compatibility?

A: Mechanical compatibility is established through matching package type (2-SMD, Gull Wing Exposed Pad), physical dimensions (5.00mm x 5.00mm), and maximum height (1.48mm). Optical compatibility requires identical color (white) and viewing angle (120°). Thermal compatibility is confirmed by matching thermal resistance (11°C/W). Electrical parameters (forward voltage and current ratings) determine circuit design feasibility but do not prevent substitution if circuit redesign is performed.

Q: Why is the MX3SWT-A1-0000-0008B6 classified as obsolete?

A: The XLamp® MX-3S series has reached end-of-life status. The MX3AWT-A1-0000-0008B4 from the active XLamp® MX-3 series represents the current product line continuation from CreeLED, Inc.

Q: Are there compliance differences between the main part and substitute?

A: The MX3AWT-A1-0000-0008B4 is RoHS Compliant, while the MX3SWT-A1-0000-0008B6 does not specify RoHS status. Both components are REACH Unaffected and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Both maintain MSL 2A (4 Weeks) moisture sensitivity levels.

Q: What is the impact of the efficiency difference (63 lm/W versus 59 lm/W)?

A: The MX3SWT-A1-0000-0008B6 delivers 63 lumens per watt, while the MX3AWT-A1-0000-0008B4 delivers 59 lumens per watt. Despite this 4 lm/W difference, both components produce identical luminous flux (77lm) at their respective test currents. The efficiency difference reflects the different electrical operating points of each LED design.

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

A: The MX3AWT-A1-0000-0008B4 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The main part MX3SWT-A1-0000-0008B6 does not specify packaging format in the provided data.
