Substitute Part Grouping Explanation

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

Mandatory Matching Criteria:

• Color and CCT: White, Cool 5000K
• Package / Case: 2-SMD, Gull Wing Exposed Pad
• Size / Dimension: 5.00mm x 5.00mm
• Height - Seated (Max): 1.48mm
• Viewing Angle: 120°
• Mounting Type: Surface Mount
• Thermal Resistance: 11°C/W

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
• Flux Output: Substitutes must maintain comparable luminous output within acceptable engineering tolerances
• Lumens/Watt Efficiency: Substitutes should maintain similar or improved efficiency
• CRI: Substitutes should maintain CRI of 75 or higher
• Product Status: Active status substitutes are preferred for obsolete parts

The MX3AWT-A1-0000-000DDZ qualifies as a substitute based on matching color, CCT, package type, physical dimensions, thermal characteristics, and viewing angle. Differences in forward voltage and test current require circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000DDZ is an active product substitute for the obsolete MX3SWT-A1-0000-000CDZ. Both components share identical physical dimensions, thermal characteristics, color temperature, CRI rating, and viewing angle, establishing mechanical and optical compatibility.

Key differences requiring circuit evaluation:

Forward Voltage Difference: The substitute operates at 3.7V versus 10.7V for the main part. Applications using the MX3SWT-A1-0000-000CDZ in series-connected configurations or high-voltage driver circuits must be re-evaluated for the lower voltage requirement of the MX3AWT-A1-0000-000DDZ.

Current Rating Difference: The substitute is rated for 350mA test current and 500mA maximum current, compared to 115mA test and 175mA maximum for the main part. Driver circuits must be capable of supplying the higher current demand.

Luminous Output: The substitute delivers 111lm versus 104lm for the main part, representing a 6.7% increase in flux output at comparable efficiency (86 lm/W versus 85 lm/W).

Compliance Status: The MX3AWT-A1-0000-000DDZ carries active product status and RoHS compliance certification, providing supply chain continuity and regulatory alignment for new designs and production restocking.

Both components maintain identical MSL 2A classification and REACH unaffected status, ensuring equivalent handling and environmental compliance requirements.

Frequently Asked Questions (FAQ)

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

A: Physical and optical compatibility is confirmed. However, the significant difference in forward voltage (3.7V versus 10.7V) and test current (350mA versus 115mA) requires circuit-level evaluation. Direct substitution is only possible if the driver circuit can accommodate these electrical parameter changes.

Q: What is the primary reason for substitution?

A: The MX3SWT-A1-0000-000CDZ is classified as obsolete. The MX3AWT-A1-0000-000DDZ is an active product from the same manufacturer, ensuring ongoing availability and supply chain reliability.

Q: Are the package dimensions identical?

A: Yes. Both components use 2-SMD, Gull Wing Exposed Pad packaging with 5.00mm x 5.00mm footprint and 1.48mm maximum seated height. PCB layout compatibility is confirmed.

Q: What is the thermal performance difference?

A: Both components have identical thermal resistance of 11°C/W, confirming equivalent thermal management characteristics in the application circuit.

Q: Does the substitute meet RoHS requirements?

A: The MX3AWT-A1-0000-000DDZ is RoHS compliant. The main part does not specify RoHS status. For applications requiring RoHS certification, the substitute provides documented compliance.

Q: How does the luminous output compare?

A: The substitute delivers 111lm at 350mA versus 104lm at 115mA for the main part. Both maintain 5000K color temperature and 75 CRI, with comparable efficiency ratings (86 lm/W and 85 lm/W respectively).

Q: Are moisture sensitivity requirements the same?

A: Yes. Both components are classified as MSL 2A (4 Weeks), requiring identical handling, storage, and reflow procedures.
