Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AF6 is determined by the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain warm white at 3700K to preserve color consistency in lighting applications.

Viewing Angle: The 120° viewing angle is a fixed optical characteristic that must be maintained for beam pattern compatibility.

Package and Mounting: Both parts use 2-SMD, Gull Wing Exposed Pad configuration with identical 5.00 mm × 5.00 mm footprint and 1.48 mm maximum seated height, ensuring PCB layout compatibility.

Thermal Resistance: The 11°C/W thermal resistance must be preserved to maintain thermal management performance in the application circuit.

CRI (Color Rendering Index): A CRI of 80 (Typical) is required for color fidelity in warm white applications.

The identified substitute, MX3AWT-A1-0000-000BF6, shares these critical parameters. However, this substitute operates at significantly different electrical characteristics (3.7V forward voltage, 350 mA test current) compared to the main part (10.7V, 115 mA). This electrical difference requires circuit redesign and is not a direct pin-for-pin replacement.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000BF6 is the identified substitute for the obsolete MX3SWT-A1-0000-000AF6. Both components are manufactured by CreeLED, Inc., and share identical optical, thermal, and mechanical characteristics (3700K color temperature, 120° viewing angle, 11°C/W thermal resistance, and 5.00 mm × 5.00 mm footprint).

The substitute part is currently in active production status, ensuring long-term availability compared to the obsolete main part. The MX3AWT-A1-0000-000BF6 carries RoHS compliance certification, providing environmental regulatory advantage.

Critical consideration: The substitute operates at 3.7V forward voltage and 350 mA test current, compared to the main part's 10.7V and 115 mA. This represents a fundamental electrical difference requiring complete circuit redesign. The substitute cannot be used as a direct replacement in existing designs without modification to power supply, current limiting, and thermal management circuits.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BF6 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AF6?

A: No. While both parts share identical optical (3700K, 120° viewing angle), thermal (11°C/W), and mechanical (5.00 mm × 5.00 mm, 1.48 mm height) characteristics, the electrical specifications differ significantly. The substitute operates at 3.7V forward voltage with 350 mA test current, whereas the main part operates at 10.7V with 115 mA. Circuit redesign is required.

Q: Are the package footprints identical between these two parts?

A: Yes. Both the MX3SWT-A1-0000-000AF6 and MX3AWT-A1-0000-000BF6 use 2-SMD, Gull Wing Exposed Pad configuration with 5.00 mm × 5.00 mm footprint and 1.48 mm maximum seated height. PCB layout compatibility is maintained.

Q: What is the color temperature difference between these parts?

A: Both parts are specified at 3700K warm white with 80 CRI (Typical). No color temperature difference exists.

Q: Why is the main part listed as obsolete?

A: The MX3SWT-A1-0000-000AF6 is classified as obsolete by the manufacturer. The MX3AWT-A1-0000-000BF6 represents the active production alternative from CreeLED, Inc.

Q: Does the substitute part have better environmental compliance?

A: Yes. The MX3AWT-A1-0000-000BF6 is RoHS Compliant, whereas RoHS status is not specified for the main part. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: What is the flux output difference?

A: The main part delivers 91 lm at 115 mA test current. The substitute delivers 97 lm at 350 mA test current. Both achieve approximately 74–75 lm/W efficiency.
