Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3SWT-A1-0000-000AA2 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Color: White, Neutral
• CCT (Correlated Color Temperature): 4750K
• Viewing Angle: 120°
• Mounting Type: Surface Mount
• Package / Case: 2-SMD, Gull Wing Exposed Pad
• Physical Dimensions: 5.00mm × 5.00mm
• Height - Seated (Max): 1.48mm
• CRI (Color Rendering Index): 75 (Typ)

Allowable Variation Parameters:

• Forward Voltage (Vf): Substitutes may operate at different voltage levels if the application circuit can accommodate the change
• Test Current: Substitutes may have different rated test currents
• Maximum Current: Substitutes may have different maximum current ratings
• Lumens/Watt Efficiency: Substitutes may have different efficiency values
• Thermal Resistance: Substitutes may have different thermal characteristics
• Product Status: Active substitutes are acceptable for obsolete parts
• Packaging Format: Tape & Reel (TR) is acceptable for component-level substitution

The MX3AWT-A1-0000-000AA2 qualifies as a substitute based on matching all mandatory criteria while differing in electrical operating parameters and product status.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AA2 is an active product substitute for the obsolete MX3SWT-A1-0000-000AA2. Both components share identical color temperature (4750K), color rendering index (75 Typ), viewing angle (120°), physical dimensions (5.00mm × 5.00mm), and thermal characteristics (11°C/W).

The primary difference lies in electrical operating parameters: the MX3AWT operates at 3.7V forward voltage with 350mA test current, compared to the MX3SWT's 10.7V and 115mA. This voltage and current differential requires circuit redesign to accommodate the substitute component's electrical characteristics.

The MX3AWT-A1-0000-000AA2 carries RoHS Compliant certification, providing regulatory advantage for new designs and production continuity. Both components maintain identical moisture sensitivity levels (2A, 4 Weeks) and thermal resistance specifications.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000AA2 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AA2?

A: No. While both components share identical physical dimensions, package configuration, and optical characteristics (color, CCT, CRI, viewing angle), the MX3AWT operates at significantly different electrical parameters (3.7V vs. 10.7V forward voltage; 350mA vs. 115mA test current). Circuit redesign is required to accommodate these differences.

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

A: Yes. Both the MX3SWT-A1-0000-000AA2 and MX3AWT-A1-0000-000AA2 use the same 2-SMD, Gull Wing Exposed Pad package with 5.00mm × 5.00mm dimensions and 1.48mm maximum seated height. PCB layout compatibility is maintained.

Q: What is the primary reason for substitution?

A: The MX3SWT-A1-0000-000AA2 is obsolete. The MX3AWT-A1-0000-000AA2 is an active product from the same manufacturer that maintains optical and thermal specifications while offering continued supply availability and RoHS compliance.

Q: Do both parts produce the same light output?

A: Both components deliver 91 lumens at 25°C (87–94 lm range). However, they achieve this output at different operating currents: the MX3SWT at 115mA and the MX3AWT at 350mA. Efficiency differs slightly (74 lm/W vs. 70 lm/W respectively).

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

A: The MX3AWT-A1-0000-000AA2 is supplied in Tape & Reel (TR) format for production environments.
