Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000AE4 is based on the following criteria:

Mandatory Matching Parameters:

• Color and CCT: White, Neutral 4500K
• Mounting Type: Surface Mount
• Package / Case: 2-SMD, Gull Wing Exposed Pad
• Size / Dimension: 5.00 mm × 5.00 mm
• Height - Seated (Max): 1.48 mm
• Viewing Angle: 120°
• Thermal Resistance: 11°C/W
• Moisture Sensitivity Level: 2A (4 Weeks)

Allowable Variation Parameters:

• Forward Voltage (Vf): Substitutes may differ; circuit design must accommodate the specified operating voltage
• Test Current and Maximum Current: Substitutes may operate at different current levels; power supply and current limiting must be adjusted accordingly
• Flux Output: Substitutes may deliver different lumen values; application brightness requirements determine acceptability
• Lumens/Watt Efficiency: Substitutes may have different efficiency ratings
• CRI: Substitutes may have different color rendering index values

The identified substitute MX3AWT-A1-0000-000BE4 matches all mandatory parameters and is from the same manufacturer family (XLamp® MX series).

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000BE4 is the identified substitute for the obsolete MX3SWT-A1-0000-000AE4. Selection of this substitute requires the following engineering considerations:

Product Status: The substitute is classified as Active, ensuring ongoing availability and manufacturing support compared to the obsolete main part.

Compliance: The substitute carries RoHS Compliant certification, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Electrical Characteristics: The substitute operates at 3.7V forward voltage versus 10.7V for the main part. This represents a significant voltage reduction that requires circuit redesign. The substitute operates at 350mA test current versus 115mA for the main part, necessitating power supply and current limiting adjustments.

Optical Performance: The substitute delivers 97 lumens at 25°C versus 91 lumens for the main part, representing a 6.6% increase in flux output. Both parts maintain identical CRI (75 Typ) and viewing angle (120°) specifications.

Thermal and Mechanical Compatibility: The substitute maintains identical thermal resistance (11°C/W), package type (2-SMD, Gull Wing Exposed Pad), physical dimensions (5.00 mm × 5.00 mm), and height (1.48 mm), ensuring PCB layout and thermal management compatibility.

Packaging: The substitute is supplied in Tape & Reel (TR) format, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BE4 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AE4?

A: No. While both parts share identical physical dimensions, package type, and thermal characteristics, the substitute operates at 3.7V forward voltage compared to 10.7V for the main part. Circuit redesign is required to accommodate the different voltage and current specifications. PCB layout and thermal management remain compatible.

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

A: The primary differences are forward voltage (10.7V vs. 3.7V), test current (115mA vs. 350mA), maximum current (175mA vs. 500mA), and flux output (91 lm vs. 97 lm). Both parts maintain identical color temperature (4500K), CRI (75), viewing angle (120°), and physical dimensions (5.00 mm × 5.00 mm).

Q: Why is the substitute part classified as Active while the main part is Obsolete?

A: The MX3AWT-A1-0000-000BE4 represents a current production part within the XLamp® MX series product line, ensuring long-term availability and manufacturing support. The MX3SWT-A1-0000-000AE4 has been discontinued by the manufacturer.

Q: Are there any compliance differences between the two parts?

A: The substitute is RoHS Compliant, whereas the main part does not specify RoHS status. Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The substitute's RoHS compliance may be required for certain applications or regulatory jurisdictions.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts use identical 2-SMD, Gull Wing Exposed Pad packaging with 5.00 mm × 5.00 mm dimensions and 1.48 mm maximum seated height. PCB footprints and assembly processes remain compatible.

Q: What circuit modifications are necessary to use the substitute part?

A: The power supply voltage must be reduced from 10.7V to 3.7V, and current limiting must be adjusted from 115mA to 350mA. Thermal management design remains unchanged due to identical thermal resistance (11°C/W). Consult the detailed datasheets for both parts to confirm all electrical and thermal requirements for your specific application.
