MX3SWT-A1-0000-000C50 Equivalent & Substitute Parts

Part Overview

The MX3SWT-A1-0000-000C50 is a CreeLED XLamp® MX-3S cool white LED (6000K) in a 2-SMD surface mount package with exposed pad. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The part delivers 104 lumens at 115mA forward current with a typical forward voltage of 10.7V and 120° viewing angle. Due to its obsolete status, equivalent parts from the active XLamp® product line are necessary for design continuity and supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MX3SWT-A1-0000-000C50 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Color and CCT: White, Cool 6000K (identical spectral output required)
• Package Type: 2-SMD, Gull Wing Exposed Pad (mechanical and thermal compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Physical Dimensions: 5.00 mm × 5.00 mm footprint (board layout compatibility)
• Height - Seated: 1.48 mm maximum (clearance and assembly compatibility)
• Thermal Resistance: 11°C/W (thermal management equivalence)
• Viewing Angle: 120° (optical performance equivalence)
• CRI: 75 (Typ) (color rendering consistency)

Electrical Parameters (Functional Equivalence): Substitutes must operate within the same electrical envelope. The MX3SWT operates at 10.7V typical forward voltage with 115 mA test current. Substitute parts may differ in forward voltage and current specifications provided they deliver equivalent luminous flux output and maintain compatibility with existing circuit designs.

Compliance and Supply Status: Active product status and RoHS compliance are preferred for long-term availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000E50 is the designated substitute for the obsolete MX3SWT-A1-0000-000C50 based on the following engineering criteria:

Product Status: The MX3AWT is active and in production, ensuring long-term supply availability and support. The MX3SWT is obsolete and subject to end-of-life constraints.

Compliance: The MX3AWT carries RoHS Compliant certification, meeting current regulatory requirements for electronic components in regulated markets. This status supports compliance with environmental and safety directives.

Mechanical Compatibility: Both parts share identical package geometry (2-SMD, Gull Wing Exposed Pad), footprint (5.00 mm × 5.00 mm), and height (1.48 mm maximum), ensuring direct PCB layout compatibility without redesign.

Optical and Thermal Equivalence: Both parts deliver 120° viewing angle, 75 CRI, and 11°C/W thermal resistance, maintaining optical performance and thermal management characteristics.

Electrical Differences: The MX3AWT operates at 3.7V typical forward voltage with 350 mA test current, compared to the MX3SWT's 10.7V and 115 mA. Circuit designs must accommodate this voltage and current shift. The MX3AWT delivers higher luminous flux (118 lm vs. 104 lm) and improved efficiency (91 lm/W vs. 85 lm/W).

Supply Status: The MX3AWT has 1244 units in stock (new original), compared to 708 units of the obsolete MX3SWT, supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000E50 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000C50?

A: Mechanical and optical compatibility is direct. The footprint, package type, height, viewing angle, and CRI are identical. However, the forward voltage differs significantly (3.7V vs. 10.7V) and forward current differs (350 mA vs. 115 mA). Circuit redesign is required to accommodate these electrical parameters. The higher luminous flux output (118 lm vs. 104 lm) may require brightness adjustment in the application.

Q: What are the key differences between the MX3SWT and MX3AWT series?

A: The MX3SWT is part of the XLamp® MX-3S series (obsolete), while the MX3AWT belongs to the XLamp® MX-3 series (active). Both deliver 6000K cool white light with 120° viewing angle and 75 CRI. The MX3AWT operates at lower forward voltage (3.7V vs. 10.7V) and higher current (350 mA vs. 115 mA), with improved luminous efficiency (91 lm/W vs. 85 lm/W).

Q: Are there any packaging differences between these parts?

A: Both parts use identical 2-SMD, Gull Wing Exposed Pad packages with 5.00 mm × 5.00 mm footprints and 1.48 mm maximum seated height. The MX3AWT is supplied in Tape & Reel (TR) packaging, while the MX3SWT packaging format is not specified. Both maintain 2A MSL (4 Weeks) moisture sensitivity.

Q: What compliance certifications apply to the MX3AWT substitute?

A: The MX3AWT is RoHS Compliant and REACH Unaffected. Both parts carry ECCN EAR99 and HTSUS 8541.41.0000 classifications. The MX3AWT's RoHS compliance supports regulatory requirements in markets with environmental directives.

Q: How do the thermal characteristics compare?

A: Both parts have identical thermal resistance of 11°C/W, ensuring equivalent thermal management performance in circuit designs. Thermal design considerations remain unchanged during substitution.

Q: What is the impact of the higher luminous flux in the MX3AWT?

A: The MX3AWT delivers 118 lm (114–122 lm range) compared to the MX3SWT's 104 lm (100–107 lm range). This represents approximately 13% higher light output. Applications requiring fixed brightness levels may need circuit adjustment or optical attenuation to match original performance specifications.
