Substitute Part Grouping Explanation

The MX6AWT-H1-0000-000D51 is identified as a substitute for the MX6SWT-H1-0000-000F51 based on the following criteria:

Common Parameters (Substitution Basis):

• Color and CCT: Both White, Cool 6500K
• Mounting Type: Both Surface Mount
• Package / Case: Both 2-SMD, Gull Wing configuration
• Size / Dimension: Both 5.00mm × 5.00mm
• Height - Seated (Max): Both 1.48mm
• Thermal Resistance: Both 5°C/W
• Viewing Angle: Both 120°
• CRI: Both 80
• Moisture Sensitivity Level: Both 2A (4 Weeks)

Differing Parameters (Design Considerations):

• Voltage - Forward (Vf): MX6SWT operates at 20V; MX6AWT operates at 3.3V
• Current - Test: MX6SWT at 60mA; MX6AWT at 300mA
• Current - Maximum: MX6SWT 175mA; MX6AWT 1A
• Flux @ 25°C: MX6SWT 126 lm; MX6AWT 111 lm
• Lumens/Watt: MX6SWT 105 lm/W; MX6AWT 112 lm/W
• Product Status: MX6SWT is Obsolete; MX6AWT is Active
• Series: MX6SWT is XLamp® MX-6S; MX6AWT is XLamp® MX-6

Substitution is valid when circuit design accommodates the lower forward voltage and higher operating current of the MX6AWT variant.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000D51 is the active production equivalent for the obsolete MX6SWT-H1-0000-000F51. Selection of the MX6AWT requires circuit redesign to accommodate the significantly different electrical characteristics: 3.3V forward voltage versus 20V, and 300mA test current versus 60mA.

The MX6AWT offers advantages in active product status and RoHS compliance certification. Both parts maintain identical mechanical compatibility (5.00mm × 5.00mm footprint, 1.48mm height, 120° viewing angle) and thermal characteristics (5°C/W). Color temperature and CRI specifications are identical at 6500K and 80 respectively.

Direct pin-for-pin substitution is not feasible due to voltage and current differences. Circuit-level modifications to power delivery and current limiting are mandatory for successful implementation of the MX6AWT as a replacement.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000D51 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000F51?

A: No. While both parts share identical mechanical dimensions (5.00mm × 5.00mm), footprint, and viewing angle, the electrical characteristics differ significantly. The MX6AWT operates at 3.3V with 300mA test current, whereas the MX6SWT operates at 20V with 60mA test current. Circuit redesign is required.

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

A: Substitution is based on matching color temperature (6500K), CRI (80), viewing angle (120°), mounting type (surface mount), physical dimensions (5.00mm × 5.00mm), and thermal resistance (5°C/W). Voltage and current ratings are design-dependent and do not prevent substitution if the circuit is modified accordingly.

Q: Why is the MX6SWT-H1-0000-000F51 listed as obsolete?

A: The MX6SWT is part of the XLamp® MX-6S series, which has been superseded by the active XLamp® MX-6 series (represented by the MX6AWT). CreeLED has transitioned production to the newer MX-6 platform.

Q: Are there packaging differences between these parts?

A: Yes. The MX6SWT uses a 2-SMD, Gull Wing package, while the MX6AWT uses a 2-SMD, Gull Wing Exposed Pad package. The exposed pad on the MX6AWT provides improved thermal management. Both are compatible with standard SMD assembly processes.

Q: What is the inventory status of these parts?

A: The MX6SWT-H1-0000-000F51 has 1053 pieces in stock as new original inventory. The MX6AWT-H1-0000-000D51 has 777 pieces in stock as new original inventory in Tape & Reel packaging.

Q: Is the MX6AWT-H1-0000-000D51 RoHS compliant?

A: Yes. The MX6AWT is RoHS compliant. The MX6SWT RoHS status is not specified in the available documentation.
