Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000CB3 is evaluated based on the following critical parameters that define functional and mechanical compatibility:

Mechanical Compatibility Parameters:

• Package / Case: 2-SMD, Gull Wing Exposed Pad (identical footprint required)
• Size / Dimension: 5.00mm x 5.00mm (identical)
• Height - Seated (Max): 1.48mm (identical)
• Mounting Type: Surface Mount (identical)

Optical Compatibility Parameters:

• Color: White (identical)
• Viewing Angle: 120° (identical)

Electrical Compatibility Considerations:

• Forward Voltage (Vf): 10.7V (main part) vs. 3.7V (substitute) — represents significant electrical difference
• Current - Test: 115mA (main part) vs. 350mA (substitute) — represents significant current difference
• Flux Output: 104lm (main part) vs. 111lm (substitute) — comparable luminous output
• Lumens/Watt: 85 lm/W (main part) vs. 86 lm/W (substitute) — comparable efficiency

The identified substitute MX3AWT-A1-0000-000DB1 maintains identical mechanical and optical parameters. However, the electrical characteristics differ substantially: the substitute operates at 3.7V with 350mA test current, compared to the main part's 10.7V at 115mA. This electrical difference requires circuit-level evaluation to determine suitability for specific applications.

Engineering Selection Recommendations

Product Status Consideration: The MX3SWT-A1-0000-000CB3 is classified as obsolete. The identified substitute MX3AWT-A1-0000-000DB1 carries active product status from CreeLED, Inc., ensuring ongoing availability and manufacturing support.

Compliance and Certification: Both parts maintain REACH Unaffected status. The substitute part carries RoHS Compliant certification, whereas RoHS status is not specified for the main part. This represents an improvement in regulatory compliance for new designs.

Mechanical and Optical Equivalence: The substitute part maintains identical mechanical footprint (5.00mm x 5.00mm, 1.48mm height), package configuration (2-SMD, Gull Wing Exposed Pad), and optical characteristics (120° viewing angle, white color). PCB layout and mechanical assembly compatibility is preserved.

Electrical Differences: The substitute operates at 3.7V typical forward voltage with 350mA test current, compared to the main part's 10.7V at 115mA. This represents a fundamental electrical difference that requires circuit redesign. Applications utilizing the main part's higher voltage characteristic cannot directly substitute the lower voltage alternative without power supply and current limiting modifications.

Luminous Output: Both parts deliver comparable luminous output (104lm vs. 111lm) and efficiency (85 lm/W vs. 86 lm/W), indicating functional equivalence for brightness-dependent applications.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000DB1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000CB3?

A: Direct mechanical substitution is possible due to identical package dimensions and footprint. However, electrical redesign is required. The substitute operates at 3.7V versus 10.7V, necessitating modifications to power supply voltage and current limiting circuitry.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical package configuration (2-SMD, Gull Wing Exposed Pad), dimensions (5.00mm x 5.00mm), and height (1.48mm). PCB footprints are compatible without layout modification.

Q: How do the optical characteristics compare?

A: Both parts emit white light at 120° viewing angle. Luminous output is comparable (104lm vs. 111lm), and efficiency is nearly identical (85 lm/W vs. 86 lm/W).

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

A: The main part is obsolete, indicating discontinued manufacturing. The substitute is active, ensuring continued availability and manufacturing support from CreeLED, Inc.

Q: Are there compliance differences between the parts?

A: Both maintain REACH Unaffected status. The substitute carries RoHS Compliant certification, whereas RoHS status is not specified for the main part.

Q: What thermal characteristics should be considered?

A: Both parts have identical thermal resistance of 11°C/W and moisture sensitivity level of 2A (4 Weeks), indicating equivalent thermal management requirements.

Q: Why is the current rating significantly different?

A: The substitute part (MX3AWT-A1-0000-000DB1) operates at lower voltage (3.7V) with higher current (350mA test, 500mA maximum) compared to the main part (10.7V, 115mA test, 175mA maximum). This reflects different LED die design and operating characteristics between the XLamp® MX-3S and XLamp® MX-3 series.
