MX3SWT-A1-0000-0008A6 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-0008A6 is a CreeLED XLamp® MX-3S warm white LED (3500K) designed for surface mount applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production and maintenance requirements. The MX-3S series has been superseded by newer generations within the XLamp® product line, necessitating substitute part evaluation for design continuity and supply chain management.

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-0008A6 is evaluated based on the following critical parameters that must align for functional equivalence:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must maintain warm white at 3500K to preserve color consistency in lighting applications.

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

Package and Mechanical Compatibility: The 2-SMD, Gull Wing Exposed Pad configuration with 5.00 mm × 5.00 mm footprint and 1.48 mm maximum seated height ensures PCB layout compatibility.

Thermal Resistance: The 11°C/W thermal resistance specification must be preserved to maintain thermal management performance.

Moisture Sensitivity Level: MSL 2A classification must be maintained for storage and handling consistency.

Compliance and Regulatory Status: REACH Unaffected status and ECCN EAR99 classification must be preserved.

The identified substitute part MX3AWT-A1-0000-0008A6 shares these core mechanical, optical, and regulatory parameters. However, critical electrical differences exist in forward voltage and current ratings, which are documented in the parameter comparison table below.

Engineering Selection Recommendations

The MX3AWT-A1-0000-0008A6 is an active product with RoHS compliance certification, providing supply chain continuity for the obsolete MX3SWT-A1-0000-0008A6. Both parts maintain identical optical characteristics (3500K warm white, 77 lm flux, 120° viewing angle, 80 CRI) and mechanical compatibility (5.00 mm × 5.00 mm footprint, 1.48 mm height, 11°C/W thermal resistance).

The primary distinction lies in electrical specifications: the MX3AWT operates at 3.7V forward voltage with 350 mA test current, compared to the MX3SWT's 10.7V and 115 mA. This represents a fundamental difference in LED die architecture between the MX-3 and MX-3S series. Circuit design modifications are required to accommodate the lower voltage and higher current characteristics of the substitute part. Power supply and current-limiting circuitry must be re-evaluated to ensure proper operation within the specified 500 mA maximum current rating.

The active product status and RoHS compliance of the MX3AWT-A1-0000-0008A6 support long-term availability and regulatory alignment for new designs or production continuity.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-0008A6 be used as a direct drop-in replacement for the MX3SWT-A1-0000-0008A6?

A: No. While both parts share identical mechanical footprint, optical characteristics, and thermal properties, the electrical specifications differ significantly. The MX3AWT operates at 3.7V / 350 mA versus the MX3SWT's 10.7V / 115 mA. Circuit redesign is required to accommodate these differences.

Q: Are the package dimensions identical between these parts?

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

Q: What is the significance of the product status difference?

A: The MX3SWT-A1-0000-0008A6 is classified as obsolete, indicating discontinued manufacturing. The MX3AWT-A1-0000-0008A6 is active, providing ongoing availability and supply chain support for new production.

Q: Do both parts meet the same regulatory requirements?

A: Both parts maintain REACH Unaffected status and ECCN EAR99 classification. The MX3AWT-A1-0000-0008A6 additionally carries RoHS Compliant certification, providing enhanced regulatory alignment for current manufacturing standards.

Q: Is the color temperature identical between these parts?

A: Yes. Both parts are specified as warm white at 3500K with 80 CRI (typical), ensuring color consistency in lighting applications.

Q: What thermal management considerations apply to the MX3AWT-A1-0000-0008A6?

A: Both parts share identical thermal resistance of 11°C/W. However, the higher operating current of the MX3AWT (350 mA test, 500 mA maximum) generates proportionally higher power dissipation, requiring thermal design evaluation in the application circuit.
