Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000BA2 is based on the following criteria:

Matching Parameters:

• Color and CCT: White, Neutral 4750K (identical)
• Viewing Angle: 120° (identical)
• Package Type: 2-SMD, Gull Wing Exposed Pad (identical)
• Physical Dimensions: 5.00 mm × 5.00 mm (identical)
• Height (Seated Max): 1.48 mm (identical)
• Thermal Resistance: 11°C/W (identical)
• CRI: 75 (Typ) (identical)
• MSL Rating: 2A (4 Weeks) (identical)

Allowable Variations: The MX3AWT-A1-0000-000CA2 operates at a different voltage and current specification (3.7V / 350mA vs. 10.7V / 115mA), representing a different die configuration within the same product family. This substitution is valid only when the application circuit can accommodate the lower forward voltage and higher test current requirements.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000CA2 is the active production equivalent for the obsolete MX3SWT-A1-0000-000BA2. Both components share identical mechanical packaging, thermal characteristics, and optical properties (color, CCT, CRI, viewing angle).

The primary design consideration is the voltage and current specification change. The substitute operates at 3.7V typical forward voltage with a 350mA test current, compared to the original 10.7V / 115mA specification. This represents a different LED die configuration optimized for lower-voltage applications.

The MX3AWT-A1-0000-000CA2 carries RoHS Compliant certification and is in active production status, ensuring long-term availability and supply chain stability. Both parts maintain identical MSL ratings and thermal resistance characteristics, supporting direct mechanical and thermal integration into existing designs.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000CA2 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BA2?

A: Mechanical and thermal compatibility is confirmed. However, the forward voltage differs significantly (3.7V vs. 10.7V). Direct substitution requires circuit redesign to accommodate the lower voltage specification. The substitute cannot be used in applications designed for the original 10.7V operating point without driver circuit modification.

Q: What are the key differences between these parts?

A: Both parts are neutral white 4750K LEDs in identical 5.00 mm × 5.00 mm packages with 120° viewing angles. The MX3SWT-A1-0000-000BA2 operates at 10.7V / 115mA, while the MX3AWT-A1-0000-000CA2 operates at 3.7V / 350mA. Luminous output is comparable (97 lm vs. 104 lm), and luminous efficacy is nearly identical (79 lm/W vs. 80 lm/W).

Q: Is the MX3AWT-A1-0000-000CA2 available in the same packaging format?

A: Yes. Both parts use 2-SMD, Gull Wing Exposed Pad configuration with identical physical dimensions and height specifications. The substitute is supplied in Tape & Reel (TR) packaging, supporting automated assembly processes.

Q: What compliance certifications apply to the substitute part?

A: The MX3AWT-A1-0000-000CA2 is RoHS Compliant and carries REACH Unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Q: Are there any thermal or reliability differences?

A: Thermal resistance is identical at 11°C/W for both parts. MSL ratings are identical at 2A (4 Weeks). The substitute is in active production status, providing ongoing design support and supply continuity.
