MX3SWT-A1-0000-000AAA Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-000AAA is a CreeLED XLamp® MX-3S warm white LED (2700K) designed for surface mount applications. This component delivers 91 lumens at 115mA with a forward voltage of 10.7V and a 120° viewing angle. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing production, maintenance, and design continuity. Equivalent parts must maintain the same color temperature, viewing angle, package footprint, and thermal characteristics while accommodating application-specific voltage and current requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AAA is determined by the following critical parameters:

Mandatory Matching Criteria:

• Color temperature: 2700K warm white
• Color Rendering Index (CRI): 80 (Typ)
• Viewing angle: 120°
• Package type: 2-SMD, Gull Wing Exposed Pad
• Physical footprint: 5.00mm × 5.00mm
• Height: 1.48mm maximum
• Thermal resistance: 11°C/W
• Moisture sensitivity: 2A (4 Weeks)

Application-Dependent Parameters (may vary based on circuit design):

• Forward voltage (Vf)
• Test current and maximum current ratings
• Luminous flux output
• Lumens/Watt efficiency

The MX3AWT-A1-0000-000AAA qualifies as a substitute because it maintains all mandatory matching criteria. However, the substitute operates at significantly different electrical parameters (3.7V forward voltage vs. 10.7V, and 350mA test current vs. 115mA), requiring circuit redesign or the use of appropriate current-limiting and voltage regulation components.

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AAA is the identified substitute for the obsolete MX3SWT-A1-0000-000AAA. Selection of this substitute is supported by the following factors:

Product Status: The MX3AWT-A1-0000-000AAA carries Active product status, ensuring ongoing availability and supply chain continuity compared to the Obsolete MX3SWT-A1-0000-000AAA.

Compliance & Certifications: The MX3AWT-A1-0000-000AAA is RoHS Compliant, providing enhanced regulatory alignment for new designs and manufacturing environments. Both parts maintain REACH Unaffected status.

Physical & Optical Compatibility: Both parts share identical package geometry (2-SMD, Gull Wing Exposed Pad, 5.00mm × 5.00mm footprint, 1.48mm height), thermal resistance (11°C/W), and optical characteristics (2700K color temperature, 80 CRI, 120° viewing angle, 91 lm flux output).

Electrical Differences: The substitute operates at 3.7V forward voltage and 350mA test current, compared to the main part's 10.7V and 115mA. Circuit redesign or the addition of voltage regulation and current-limiting components is required for direct substitution. The substitute's efficiency is 70 lm/W versus 74 lm/W for the main part, representing a 5.4% reduction in efficiency at the substitute's rated test current.

Frequently Asked Questions (FAQ)

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

A: The MX3AWT-A1-0000-000AAA shares the same physical footprint and package type, allowing PCB-level compatibility. However, the significant difference in forward voltage (3.7V vs. 10.7V) and test current (350mA vs. 115mA) requires circuit modification. Direct substitution without electrical redesign will result in component failure or inadequate performance.

Q: Are the optical characteristics identical between these two parts?

A: Yes. Both parts deliver 91 lumens at 2700K color temperature with 80 CRI and a 120° viewing angle. The luminous flux output and color rendering are equivalent.

Q: What is the impact of the efficiency difference (74 lm/W vs. 70 lm/W)?

A: The MX3AWT-A1-0000-000AAA operates at 70 lm/W compared to 74 lm/W for the MX3SWT-A1-0000-000AAA. This 5.4% efficiency reduction occurs at the substitute's rated test current of 350mA. Actual system-level impact depends on the application's operating point and thermal management design.

Q: Does the RoHS Compliance status of the MX3AWT-A1-0000-000AAA affect compatibility?

A: RoHS Compliance of the substitute is a regulatory advantage for new designs and manufacturing environments. It does not affect electrical or optical compatibility with the main part's specifications.

Q: What are the thermal considerations for substitution?

A: Both parts have identical thermal resistance (11°C/W) and moisture sensitivity (2A, 4 Weeks). Thermal management design remains unchanged between the main part and substitute.

Q: Are there any supply chain advantages to using the MX3AWT-A1-0000-000AAA?

A: Yes. The MX3AWT-A1-0000-000AAA carries Active product status with 1103 units in stock, compared to the Obsolete MX3SWT-A1-0000-000AAA with 969 units. Active status ensures long-term availability and supply continuity.
