Substitute Part Grouping Explanation

The MX6AWT-A1-0000-000E51 is identified as a substitute for the MX6SWT-A1-0000-000E51 based on the following criteria:

Common Parameters (Substitution Basis):

• Color and CCT: Both are white LEDs with 6500K cool color temperature
• Flux Output: Both deliver 118lm (114lm – 122lm) at 25°C
• CRI: Both maintain 75 (Typ) Color Rendering Index
• Viewing Angle: Both provide 120° viewing angle
• Mounting Type: Both are surface mount components
• Physical Dimensions: Both measure 5.00mm x 5.00mm
• Height: Both have maximum seated height of 1.48mm
• Thermal Resistance: Both rated at 5°C/W
• Moisture Sensitivity: Both classified as MSL 2A (4 Weeks)

Differing Parameters (Design Considerations):

• Voltage - Forward (Vf): MX6SWT operates at 20V; MX6AWT operates at 3.3V
• Current - Test: MX6SWT uses 60mA; MX6AWT uses 300mA
• Current - Maximum: MX6SWT rated at 175mA; MX6AWT rated at 1A
• Lumens/Watt: MX6SWT delivers 98 lm/W; MX6AWT delivers 119 lm/W
• Series: MX6SWT is XLamp® MX-6S; MX6AWT is XLamp® MX-6
• Package Detail: MX6SWT uses standard Gull Wing; MX6AWT uses Gull Wing Exposed Pad
• Packaging Format: MX6SWT supplied in Cut Tape (CT) & Digi-Reel®; MX6AWT supplied in Tape & Reel (TR)
• Product Status: MX6SWT is obsolete; MX6AWT is active

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000E51 is an active product with current manufacturing status, whereas the MX6SWT-A1-0000-000E51 is obsolete. Both components share identical optical characteristics (6500K color temperature, 118lm flux output, 75 CRI, 120° viewing angle) and physical form factors (5.00mm x 5.00mm, 1.48mm height).

The primary design consideration is the electrical operating point. The MX6AWT operates at 3.3V with 300mA test current, compared to the MX6SWT's 20V at 60mA. This represents a fundamental difference in circuit topology requirements. The MX6AWT also demonstrates superior efficiency at 119 lm/W versus 98 lm/W for the MX6SWT.

Both components maintain identical thermal resistance (5°C/W) and moisture sensitivity classification (MSL 2A, 4 Weeks). The MX6AWT includes an exposed pad variant of the Gull Wing package, which may provide improved thermal management in applications requiring enhanced heat dissipation.

For new designs or production continuity where the MX6SWT-A1-0000-000E51 is no longer available, the MX6AWT-A1-0000-000E51 is suitable when circuit design accommodates the 3.3V operating voltage and 300mA test current specification.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000E51 be used as a direct drop-in replacement for the MX6SWT-A1-0000-000E51?

A: Direct substitution requires circuit redesign. While both components deliver identical light output (118lm at 6500K) and share the same physical footprint, the MX6AWT operates at 3.3V with 300mA test current, whereas the MX6SWT operates at 20V with 60mA test current. Power supply and current limiting circuits must be modified accordingly.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching color temperature (6500K), luminous flux output (118lm), Color Rendering Index (75), viewing angle (120°), mounting type (surface mount), physical dimensions (5.00mm x 5.00mm), and thermal characteristics (5°C/W). Electrical operating point (voltage and current) is a design parameter that must be accommodated in the application circuit.

Q: Are there packaging differences between these parts?

A: Yes. The MX6SWT-A1-0000-000E51 is supplied in Cut Tape (CT) & Digi-Reel® format, while the MX6AWT-A1-0000-000E51 is supplied in Tape & Reel (TR) format. Additionally, the MX6AWT features an exposed pad variant of the Gull Wing package, which may provide thermal benefits in certain applications.

Q: What is the significance of the exposed pad on the MX6AWT?

A: The exposed pad on the MX6AWT-A1-0000-000E51 provides an additional thermal path for heat dissipation. Both components maintain the same thermal resistance specification (5°C/W), but the exposed pad design may offer improved thermal performance in applications with high ambient temperatures or extended operating periods.

Q: Why is the MX6SWT-A1-0000-000E51 classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The MX6AWT-A1-0000-000E51, representing the current generation XLamp® MX-6 series, is the active product. For applications currently using the MX6SWT, transition to the MX6AWT is recommended for long-term supply assurance.

Q: Are both components RoHS compliant?

A: The MX6AWT-A1-0000-000E51 is explicitly RoHS compliant. The MX6SWT-A1-0000-000E51 RoHS status is not specified in the provided data. Both components are REACH unaffected and classified under ECCN EAR99.
