MX6SWT-H1-0000-000CB1 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-0000-000CB1 is an XLamp® MX-6S white LED in 2-SMD, Gull Wing surface mount packaging. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The part delivers 104lm at 25°C under 60mA test current with a forward voltage of 20V and 120° viewing angle. Substitution becomes necessary when original inventory is depleted or when design flexibility permits component updates to active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX6SWT-H1-0000-000CB1 is determined by the following critical parameters:

• Color: White (must match)
• Viewing Angle: 120° (must match)
• Mounting Type: Surface Mount (must match)
• Package / Case: 2-SMD, Gull Wing configuration (must match)
• Physical Dimensions: 5.00mm x 5.00mm footprint and 1.48mm maximum seated height (must match)
• Thermal Resistance: 5°C/W (must match)
• Moisture Sensitivity Level: 2A (4 Weeks) (must match)

The MX6AWT-H1-0000-000CB1 qualifies as a substitute part because it maintains identical color, viewing angle, mounting type, package configuration, physical dimensions, thermal characteristics, and moisture sensitivity specifications. While the substitute operates at different electrical parameters (3.3V forward voltage, 300mA test current, and higher efficiency at 105 lm/W), these differences do not preclude substitution when circuit design accommodates the alternative voltage and current requirements.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000CB1 is the identified substitute for the obsolete MX6SWT-H1-0000-000CB1. Selection of the substitute part is supported by the following factors:

• Product Status: The substitute is classified as Active, ensuring continued availability and supply chain stability compared to the obsolete main part.
• Regulatory Compliance: Both parts maintain REACH Unaffected status, confirming equivalent regulatory standing.
• Physical Compatibility: Identical footprint (5.00mm x 5.00mm), mounting height (1.48mm maximum), and thermal resistance (5°C/W) ensure direct PCB compatibility without layout modifications.
• Optical Characteristics: Both parts deliver identical luminous flux (104lm) and viewing angle (120°), maintaining optical performance in the application.

Substitution requires circuit design review to accommodate the different electrical operating point: the substitute operates at 3.3V forward voltage with 300mA test current, compared to the main part's 20V and 60mA specifications. The substitute demonstrates higher efficiency (105 lm/W versus 87 lm/W), which may provide secondary benefits in power management.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000CB1 be used as a direct drop-in replacement for the MX6SWT-H1-0000-000CB1?

A: Physical and optical compatibility is confirmed. The substitute maintains identical footprint, mounting height, thermal resistance, and luminous flux specifications. However, the circuit design must be evaluated to accommodate the different forward voltage (3.3V versus 20V) and test current (300mA versus 60mA) requirements.

Q: What are the key differences between these two parts?

A: The primary differences are electrical operating parameters. The MX6SWT-H1-0000-000CB1 operates at 20V with 60mA test current, while the MX6AWT-H1-0000-000CB1 operates at 3.3V with 300mA test current. The substitute offers higher efficiency (105 lm/W versus 87 lm/W). The substitute also features an exposed pad in the package configuration and is classified as Active rather than Obsolete.

Q: Are there any package differences that affect PCB assembly?

A: Both parts use 2-SMD, Gull Wing surface mount packages with identical physical dimensions and mounting height. The substitute includes an exposed pad feature, which may provide thermal management benefits but does not prevent substitution on existing PCB layouts designed for the main part.

Q: What is the impact of the different forward voltage specifications?

A: The substitute's 3.3V forward voltage differs significantly from the main part's 20V specification. This requires circuit redesign to provide appropriate drive voltage and current limiting. The application's power supply and LED driver circuit must be evaluated for compatibility with the lower voltage requirement.

Q: Is the CRI specification important for substitution?

A: The main part specifies CRI 80, while the substitute does not provide a CRI value. If color rendering index is a critical application requirement, this difference must be evaluated against the application's color quality specifications.
