MX6SWT-H1-R250-000BA3 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-R250-000BA3 is an XLamp® MX-6S white neutral LED (4300K) in a 2-SMD gull wing surface mount package. This part is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and production continuity. The MX-6S series has been superseded by the MX-6 series, which maintains compatibility across key electrical and mechanical parameters while offering active product status.

Key Parameters

Substitute Part Grouping Explanation

The MX6AWT-H1-R250-000BA3 qualifies as a substitute based on the following alignment of critical parameters:

• Color and CCT Match: Both parts deliver white neutral light at 4300K with identical flux output (97 lm at test current)
• Optical Performance: Identical viewing angle (120°) and CRI (80)
• Mechanical Compatibility: Identical package type (2-SMD gull wing), footprint dimensions (5.00 mm × 5.00 mm), and seated height (1.48 mm)
• Thermal Properties: Identical thermal resistance (5°C/W)
• Moisture Sensitivity: Identical MSL rating (2A, 4 Weeks)

The primary differences are electrical parameters (forward voltage and test current) and product status. The MX6AWT operates at 3.3V with 300 mA test current versus the MX6SWT's 20V at 60 mA. These differences require circuit-level evaluation but do not preclude substitution in applications where the lower voltage and higher current characteristics are accommodated by the design.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-R250-000BA3 is the designated substitute for the obsolete MX6SWT-H1-R250-000BA3. Selection of the MX6AWT is supported by:

• Product Status: The MX6AWT maintains active product status with ongoing manufacturer support, whereas the MX6SWT is obsolete
• Compliance: The MX6AWT carries RoHS compliance certification, providing regulatory advantage for new designs and production
• Optical Equivalence: Identical color temperature, flux output, CRI, and viewing angle ensure optical performance parity
• Mechanical Fit: Identical footprint and height allow direct PCB layout compatibility without redesign
• Thermal Performance: Matching thermal resistance ensures equivalent thermal management characteristics

Substitution requires verification that the circuit design accommodates the MX6AWT's lower forward voltage (3.3V vs. 20V) and higher test current (300 mA vs. 60 mA). The exposed pad variant of the MX6AWT package provides enhanced thermal dissipation compared to the standard gull wing configuration of the MX6SWT.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000BA3 be used as a direct replacement for the MX6SWT-H1-R250-000BA3?

A: Mechanical and optical compatibility is direct. Electrical compatibility requires circuit-level assessment. The MX6AWT operates at 3.3V forward voltage with 300 mA test current, whereas the MX6SWT operates at 20V with 60 mA. Designs must accommodate these electrical differences through appropriate current-limiting and voltage regulation.

Q: Are there package differences between these parts?

A: Both parts use 2-SMD gull wing packages with identical footprint dimensions (5.00 mm × 5.00 mm) and seated height (1.48 mm). The MX6AWT includes an exposed pad for enhanced thermal performance. PCB layouts designed for the MX6SWT will accommodate the MX6AWT without modification.

Q: What is the significance of the MX6AWT's RoHS compliance?

A: RoHS compliance indicates the MX6AWT meets Restriction of Hazardous Substances directives, making it suitable for applications subject to environmental and regulatory requirements. The MX6SWT's RoHS status is not specified.

Q: How do the optical characteristics compare?

A: Both parts deliver identical flux output (97 lm at test current), color temperature (4300K neutral white), CRI (80), and viewing angle (120°). Optical performance is equivalent.

Q: What thermal considerations apply to substitution?

A: Both parts have identical thermal resistance (5°C/W). The MX6AWT's exposed pad provides additional thermal dissipation capability. Thermal management design remains unchanged for direct substitution.
