MX6SWT-A1-0000-0009B9 Equivalent & Substitute Parts

Part Overview

The MX6SWT-A1-0000-0009B9 is a CreeLED XLamp® MX-6S white surface mount LED in 2-SMD Gull Wing configuration. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The part delivers 84lm at 25°C under 60mA test current with a forward voltage of 20V and 120° viewing angle. Substitute parts must maintain functional equivalence in color, mounting type, package footprint, and thermal characteristics while accommodating different electrical operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-A1-0000-0009B9 is based on the following criteria:

Mechanical Compatibility: Substitute parts must maintain identical mounting type (Surface Mount), package configuration (2-SMD Gull Wing), physical dimensions (5.00mm x 5.00mm), and maximum seated height (1.48mm) to ensure PCB footprint compatibility without layout redesign.

Optical Compatibility: Substitute parts must maintain white color output and 120° viewing angle to preserve optical performance in the application.

Thermal Compatibility: Substitute parts must maintain thermal resistance of package at 5°C/W to ensure equivalent thermal management characteristics.

Electrical Parameters: While forward voltage and test current differ between the main part and substitutes, the luminous flux output at the respective test currents and lumens/watt efficiency determine functional equivalence. Substitute parts must deliver comparable light output performance within the application's electrical operating envelope.

Regulatory Compliance: Substitute parts must maintain REACH Unaffected status and EAR99 ECCN classification.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-0009B9 is the designated substitute for the obsolete MX6SWT-A1-0000-0009B9. Both parts share identical luminous flux output (84lm), viewing angle (120°), physical dimensions (5.00mm x 5.00mm), and thermal characteristics (5°C/W). The substitute part is currently in active production status, ensuring supply chain availability.

The primary difference is electrical operating parameters: the MX6AWT operates at 3.3V forward voltage with 300mA test current, compared to the MX6SWT's 20V and 60mA. This requires circuit redesign to accommodate the different voltage and current requirements. The MX6AWT demonstrates superior efficiency at 85 lm/W versus 70 lm/W for the original part.

The MX6AWT features an exposed pad variant of the 2-SMD Gull Wing package, which provides enhanced thermal dissipation compared to the standard Gull Wing configuration. The substitute part carries RoHS Compliant certification, providing additional regulatory compliance for new designs.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-0009B9 be used as a direct drop-in replacement for the MX6SWT-A1-0000-0009B9?

A: The parts are mechanically and optically compatible due to identical footprint dimensions (5.00mm x 5.00mm), height (1.48mm), and viewing angle (120°). However, electrical circuit redesign is required because the MX6AWT operates at 3.3V/300mA versus the MX6SWT's 20V/60mA. PCB layout remains compatible without modification, but power supply and current limiting circuits must be redesigned.

Q: What is the significance of the exposed pad in the MX6AWT package?

A: The 2-SMD Gull Wing Exposed Pad configuration in the MX6AWT provides direct thermal contact to the PCB, improving heat dissipation compared to the standard Gull Wing package. Both parts maintain identical thermal resistance specifications (5°C/W), indicating equivalent thermal performance when properly soldered.

Q: Are both parts suitable for new designs?

A: The MX6SWT-A1-0000-0009B9 is classified as obsolete and should not be used in new designs. The MX6AWT-A1-0000-0009B9 is in active production status and is the appropriate choice for new applications requiring white XLamp MX-series LEDs in this package configuration.

Q: How do the efficiency ratings compare?

A: The MX6AWT delivers 85 lm/W at its 300mA test current, compared to 70 lm/W for the MX6SWT at 60mA. Both parts produce identical luminous flux (84lm) at their respective test currents, but the substitute achieves higher efficiency per watt consumed.

Q: What are the moisture sensitivity requirements for storage and handling?

A: Both parts carry MSL 2A (4 Weeks) classification, requiring storage in controlled humidity environments and limiting floor life to four weeks after moisture barrier bag opening. Identical handling procedures apply to both components.
