Key Parameters

Substitute Part Grouping Explanation

The MX3SWT-A1-0000-000BA6 has one identified substitute: MX6AWT-A1-0000-000BA6. Substitution eligibility is determined by the following criteria:

Matching Parameters:

• Color and CCT: Both parts are warm white at 3500K
• Flux output: Both deliver 97 lm at test conditions (94–100 lm range)
• CRI: Both maintain 80 (Typ)
• Viewing angle: Both provide 120° beam angle
• Package form factor: Both use 2-SMD, Gull Wing Exposed Pad
• Physical dimensions: Both measure 5.00 mm × 5.00 mm
• Height: Both seated height is 1.48 mm maximum
• Moisture sensitivity: Both rated MSL 2A (4 Weeks)
• Regulatory compliance: Both REACH Unaffected

Differing Parameters:

• Forward voltage: MX3SWT operates at 10.7V; MX6AWT operates at 3.3V
• Test current: MX3SWT at 115 mA; MX6AWT at 300 mA
• Maximum current: MX3SWT at 175 mA; MX6AWT at 1A
• Efficiency: MX3SWT at 79 lm/W; MX6AWT at 98 lm/W
• Thermal resistance: MX3SWT at 11°C/W; MX6AWT at 5°C/W
• Product status: MX3SWT is obsolete; MX6AWT is active
• RoHS status: MX6AWT is RoHS Compliant

Substitution is valid when the application can accommodate the different electrical operating point (lower voltage, higher current) and when thermal management requirements align with the improved thermal resistance of the MX6AWT.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000BA6 is a direct substitute for the obsolete MX3SWT-A1-0000-000BA6 when the following conditions are met:

Electrical Compatibility: The application circuit must be capable of operating at 3.3V forward voltage and accommodating the higher test current of 300 mA. Existing current-limiting resistor or driver circuits designed for 10.7V operation require redesign.

Thermal Management: The MX6AWT provides superior thermal performance (5°C/W vs. 11°C/W), reducing junction temperature rise. This is advantageous in thermally constrained applications.

Regulatory Advantage: The MX6AWT is RoHS Compliant and carries Active product status, ensuring long-term availability and compliance with current environmental regulations. The obsolete status of the MX3SWT makes the MX6AWT the preferred choice for new designs and production continuity.

Optical and Photometric Equivalence: Both parts deliver identical flux output (97 lm), CRI (80), and viewing angle (120°), ensuring equivalent optical performance in the application.

Packaging and Assembly: Identical package form factor, dimensions, and MSL rating ensure no changes to PCB layout, assembly process, or moisture handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000BA6 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BA6?

A: No. While both parts share identical package geometry, dimensions, and optical characteristics, the MX6AWT operates at 3.3V versus the MX3SWT's 10.7V. The application circuit must be redesigned to accommodate the lower forward voltage and higher current requirements. PCB layout and component placement remain unchanged, but the power supply and current-limiting circuit require modification.

Q: What are the key differences between these two parts?

A: The primary differences are electrical operating point and thermal characteristics. The MX3SWT operates at 10.7V with 115 mA test current, while the MX6AWT operates at 3.3V with 300 mA test current. The MX6AWT provides better thermal performance (5°C/W vs. 11°C/W) and higher efficiency (98 lm/W vs. 79 lm/W). Optically and photometrically, both parts are equivalent.

Q: Is the MX6AWT suitable for applications requiring the MX3SWT's electrical specifications?

A: Only if the application circuit can be redesigned to operate at 3.3V forward voltage and 300 mA test current. If the existing design is locked to 10.7V operation, the MX6AWT is not suitable without significant circuit modification.

Q: What is the impact of the MX3SWT's obsolete status?

A: Obsolete status indicates the part is no longer manufactured and existing inventory will eventually deplete. The MX6AWT's Active status ensures continued availability and support. For new designs or long-term production, the MX6AWT is the recommended choice.

Q: Are there any compliance or regulatory differences?

A: The MX6AWT is RoHS Compliant, while the MX3SWT's RoHS status is not specified. Both parts are REACH Unaffected. For applications subject to RoHS requirements, the MX6AWT provides explicit compliance documentation.

Q: Do these parts require different handling or storage procedures?

A: Both parts carry identical MSL 2A (4 Weeks) ratings, requiring the same moisture sensitivity precautions and storage conditions. No difference in handling procedures is necessary.
