MX6SWT-H1-R250-000CF7 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-R250-000CF7 is an XLamp® MX-6S warm white LED (3200K) designed for surface mount applications requiring high color rendering index (CRI 80) and directional light output (120° viewing angle). This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-R250-000CF7 is determined by the following critical parameters:

• Color and CCT: Warm white 3200K (must match for color consistency)
• Viewing Angle: 120° (optical performance requirement)
• CRI: 80 (color rendering specification)
• Package Type: 2-SMD, Gull Wing (mechanical and thermal compatibility)
• Physical Dimensions: 5.00 mm × 5.00 mm footprint and 1.48 mm maximum height (PCB layout constraint)
• Thermal Resistance: 5°C/W (thermal management equivalence)
• Mounting Type: Surface Mount (assembly process compatibility)

The MX6AWT-H1-R250-0009F7 qualifies as a functional substitute based on matching color temperature, viewing angle, CRI, package footprint, and thermal characteristics. However, significant differences in forward voltage (3.3V vs. 20V) and test current (300 mA vs. 60 mA) require circuit redesign and are not pin-compatible without modification.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-R250-0009F7 is the documented substitute for the obsolete MX6SWT-H1-R250-000CF7. Selection of this alternative is supported by:

• Active Product Status: The MX6AWT series remains in active production, ensuring long-term availability and supply chain stability.
• RoHS Compliance: The substitute meets RoHS requirements, whereas compliance status for the main part is not specified.
• Regulatory Alignment: Both parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining regulatory consistency.
• Optical and Thermal Equivalence: Matching color temperature (3200K), CRI (80), viewing angle (120°), and thermal resistance (5°C/W) preserve optical performance and thermal management characteristics.

Critical Design Consideration: The substitute operates at 3.3V with 300 mA test current, compared to the main part's 20V at 60 mA. This represents a fundamental change in electrical operating point and requires complete circuit redesign. Direct pin-for-pin replacement is not possible without power supply and current-limiting modifications.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-0009F7 be used as a direct drop-in replacement?

A: No. While both parts share identical footprints (5.00 mm × 5.00 mm), package type (2-SMD, Gull Wing), and optical characteristics (3200K, 120° viewing angle, CRI 80), the electrical specifications differ significantly. The substitute requires 3.3V forward voltage and 300 mA test current versus the main part's 20V and 60 mA. Circuit redesign is mandatory.

Q: What are the key parameters that define substitutability for this LED?

A: Substitutability is determined by: color temperature (3200K), CRI (80), viewing angle (120°), package footprint (5.00 mm × 5.00 mm), maximum seated height (1.48 mm), thermal resistance (5°C/W), and mounting type (surface mount). Electrical parameters (forward voltage and current) are application-specific and do not define optical or mechanical compatibility.

Q: Why is the main part classified as obsolete?

A: The MX6SWT-H1-R250-000CF7 belongs to the XLamp® MX-6S series, which has been superseded by the active XLamp® MX-6 series. The substitute part represents the current production equivalent within the CreeLED product line.

Q: Are there differences in thermal management between the two parts?

A: No. Both parts have identical thermal resistance ratings of 5°C/W, indicating equivalent thermal performance in properly designed thermal interfaces.

Q: What is the impact of the exposed pad on the substitute part?

A: The MX6AWT-H1-R250-0009F7 features an exposed pad design, which enhances thermal dissipation compared to standard gull wing packages. This provides improved thermal management capability and is beneficial for high-current applications.

Q: Is the substitute available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) format, whereas the main part's packaging format is not specified. Tape & Reel is standard for high-volume surface mount assembly and is compatible with automated pick-and-place equipment.
