MX3SWT-A1-0000-000BA1 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-000BA1 is a CreeLED XLamp® MX-3S cool white LED (5000K) in a 2-SMD surface mount package with exposed pad. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The part delivers 97 lumens at 115mA forward current with a typical forward voltage of 10.7V and 79 lumens per watt efficiency. Its 120° viewing angle and compact 5.00mm × 5.00mm footprint suit general illumination and indicator applications requiring cool white spectral output.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3SWT-A1-0000-000BA1 is determined by the following criteria:

• Color and CCT Match: Substitute must be white, cool white at 5000K
• Package Compatibility: 2-SMD, Gull Wing Exposed Pad with identical 5.00mm × 5.00mm footprint and 1.48mm maximum height
• Electrical Compatibility: Forward voltage, test current, and maximum current ratings must be compatible with the application circuit
• Viewing Angle: 120° viewing angle maintained
• Thermal Characteristics: Thermal resistance of 11°C/W
• CRI Performance: Color rendering index of 75 (Typ)
• Moisture Sensitivity: MSL 2A (4 Weeks) classification

The MX3AWT-A1-0000-000CA1 qualifies as a substitute based on matching color, CCT, package geometry, viewing angle, thermal resistance, CRI, and MSL rating. However, this substitute operates at significantly different electrical parameters (3.7V forward voltage, 350mA test current versus 10.7V and 115mA), requiring circuit redesign for safe operation.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000CA1 is the identified substitute for the obsolete MX3SWT-A1-0000-000BA1. Both parts share identical mechanical compatibility, thermal characteristics, and optical properties (color, CCT, CRI, viewing angle). The substitute is currently in active production status, ensuring supply chain availability.

Critical consideration: The substitute operates at 3.7V forward voltage and 350mA test current, compared to the main part's 10.7V and 115mA. This represents a fundamental electrical difference requiring complete circuit redesign. The substitute cannot be used as a direct drop-in replacement without modifying the LED driver, current limiting resistors, and power supply configuration.

The substitute demonstrates superior luminous flux (104 lm versus 97 lm) and equivalent lumens-per-watt efficiency (80 lm/W versus 79 lm/W). The substitute carries RoHS compliance certification, whereas the main part's RoHS status is not specified. Both parts maintain identical MSL 2A (4 Weeks) moisture sensitivity ratings and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000CA1 be soldered directly into a circuit designed for the MX3SWT-A1-0000-000BA1?

A: No. The substitute has a different forward voltage (3.7V versus 10.7V) and test current (350mA versus 115mA). Direct substitution without circuit modification will result in component failure or circuit malfunction. The LED driver and current-limiting network must be redesigned for the substitute's electrical characteristics.

Q: Are the physical packages identical?

A: Yes. Both parts use a 2-SMD, Gull Wing Exposed Pad package with 5.00mm × 5.00mm footprint and 1.48mm maximum height. PCB layout and reflow profiles remain compatible.

Q: What is the difference between the XLamp® MX-3S and XLamp® MX-3 series?

A: The MX-3S is the obsolete predecessor series. The MX-3 is the current production series. Both deliver equivalent optical performance (color, CCT, CRI, viewing angle) but differ in electrical operating parameters.

Q: Does the substitute meet RoHS requirements?

A: Yes. The MX3AWT-A1-0000-000CA1 is RoHS compliant. The main part's RoHS status is not documented.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts carry MSL 2A (4 Weeks) classification, requiring identical storage and handling protocols.

Q: What is the flux difference between the two parts?

A: The substitute delivers 104 lumens at its test current (350mA) versus 97 lumens for the main part at 115mA. This represents approximately 7% higher luminous output at the substitute's rated operating point.
