Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000CA2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Color: White, Neutral
• CCT (K): 4750K
• Viewing Angle: 120°
• Package / Case: 2-SMD, Gull Wing Exposed Pad
• Size / Dimension: 5.00mm x 5.00mm
• Height - Seated (Max): 1.48mm
• Thermal Resistance: 11°C/W
• Mounting Type: Surface Mount
• CRI (Color Rendering Index): 75 (Typ)

Variable Parameters (Application-Dependent):

• Voltage - Forward (Vf): May differ based on circuit design
• Current - Test: May differ based on circuit design
• Current - Max: May differ based on circuit design
• Lumens/Watt: May vary within acceptable performance range
• Flux Output: May vary within acceptable performance range
• Product Status: Active status preferred for new designs; obsolete parts acceptable for legacy support

The identified substitute MX3AWT-A1-0000-000DA2 maintains all mandatory matching parameters while operating at different voltage and current specifications, making it suitable for applications where circuit topology accommodates the 3.7V forward voltage and 350mA test current.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000DA2 is the identified equivalent substitute for the obsolete MX3SWT-A1-0000-000CA2. Selection of this substitute is based on the following engineering criteria:

Product Status: The substitute part maintains Active product status, ensuring continued availability and manufacturing support compared to the obsolete main part.

Compliance & Certifications: The substitute part is RoHS Compliant, providing enhanced regulatory compliance for applications subject to RoHS requirements. Both parts maintain REACH Unaffected and EAR99 ECCN classifications, ensuring consistent export and regulatory treatment.

Optical & Thermal Characteristics: Both parts deliver equivalent color temperature (4750K), color rendering index (75 Typ), and viewing angle (120°). Flux output differs marginally (104lm vs. 111lm), with the substitute providing 7% higher luminous output. Thermal resistance remains identical at 11°C/W, ensuring equivalent thermal management performance.

Mechanical Compatibility: Package configuration, physical dimensions (5.00mm x 5.00mm), and height (1.48mm maximum seated height) are identical, enabling direct PCB layout compatibility without redesign.

Electrical Differences: The substitute operates at 3.7V forward voltage with 350mA test current, compared to the main part's 10.7V and 115mA. Circuit topology must accommodate these voltage and current specifications. The substitute's maximum current rating of 500mA provides operational headroom compared to the main part's 175mA maximum.

Moisture Sensitivity: Both parts maintain identical MSL 2A (4 Weeks) classification, requiring equivalent handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000DA2 be used as a direct replacement for the MX3SWT-A1-0000-000CA2 without circuit modification?

A: Direct PCB-level replacement is possible due to identical package, dimensions, and thermal characteristics. However, circuit topology must accommodate the substitute's 3.7V forward voltage and 350mA test current specifications. Voltage regulator or current-limiting circuit redesign may be required depending on the original application's power supply architecture.

Q: What are the key differences between these two parts?

A: The primary differences are voltage-current specifications and product status. The main part operates at 10.7V/115mA and is obsolete. The substitute operates at 3.7V/350mA and maintains Active status. Both deliver equivalent color temperature (4750K), viewing angle (120°), and CRI (75 Typ). The substitute provides 7% higher luminous output (111lm vs. 104lm).

Q: Are the package and mounting characteristics identical?

A: Yes. Both parts use 2-SMD Gull Wing Exposed Pad packaging with identical 5.00mm x 5.00mm dimensions and 1.48mm maximum seated height. Surface mount assembly processes and PCB footprints are compatible without modification.

Q: What is the significance of the substitute part's Active product status?

A: Active status indicates ongoing manufacturing, quality assurance, and supply chain support from CreeLED, Inc. This contrasts with the main part's Obsolete status, which indicates discontinued production and potential supply constraints. Active status provides assurance of long-term component availability for production and maintenance applications.

Q: Do both parts have equivalent thermal management characteristics?

A: Yes. Both parts maintain identical thermal resistance of 11°C/W and identical MSL 2A (4 Weeks) moisture sensitivity classification. Thermal design considerations and handling protocols are equivalent.

Q: Is the substitute part RoHS compliant?

A: Yes. The MX3AWT-A1-0000-000DA2 is RoHS Compliant. The main part's RoHS status is not specified in the provided data. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Q: What is the luminous output difference between these parts?

A: The substitute delivers 111lm at 25°C and 350mA test current, compared to the main part's 104lm at 25°C and 115mA test current. This represents approximately 7% higher luminous output. Both parts deliver equivalent lumens-per-watt efficiency (85-86 lm/W).
