MX6SWT-H1-R250-000CF6 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-R250-000CF6 is an LED Lighting XLamp® MX-6S White warm white (3700K) surface mount component manufactured by CreeLED, Inc. This part operates at 20V forward voltage with a 60mA test current, delivering 104lm at 25°C and 87 lm/W efficiency. The component features a 120° viewing angle in a 2-SMD Gull Wing package measuring 5.00mm x 5.00mm.

The product status is listed as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement continuity. Substitute parts must maintain compatibility across electrical characteristics, optical properties, and mechanical form factors while accounting for differences in voltage and current specifications.

Key Parameters

Substitute Part Grouping Explanation

The identified substitute part MX6AWT-A1-R250-000BF6 shares the following critical parameters with the main part:

Common Parameters (Substitution Basis):

• Color and CCT: White, Warm 3700K
• CRI: 80
• Viewing Angle: 120°
• Package Type: 2-SMD, Gull Wing
• Physical Dimensions: 5.00mm x 5.00mm
• Height - Seated (Max): 1.48mm
• Thermal Resistance: 5°C/W
• Moisture Sensitivity Level: 2A (4 Weeks)
• Mounting Type: Surface Mount

Key Differences: The substitute part operates at significantly different electrical parameters: 3.3V forward voltage and 300mA test current (versus 20V and 60mA for the main part). The substitute belongs to the XLamp® MX-6 series (active product status) rather than the MX-6S series. These differences require circuit-level evaluation to determine suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-R250-000BF6 is the identified substitute for the obsolete MX6SWT-H1-R250-000CF6. Selection of this substitute requires evaluation of the following factors:

Product Status: The substitute part carries Active product status, ensuring ongoing availability and manufacturing support, whereas the main part is Obsolete.

Compliance: The substitute part is RoHS Compliant, providing regulatory advantage for applications subject to RoHS requirements. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Electrical Compatibility: The substitute operates at 3.3V forward voltage with 300mA test current, representing a fundamental departure from the main part's 20V/60mA specification. Circuit redesign is required to accommodate this voltage and current difference. The substitute's maximum current rating of 1A versus the main part's 175mA reflects the different electrical architecture.

Optical Performance: Both parts deliver equivalent color temperature (3700K), CRI (80), and viewing angle (120°). The substitute produces 97lm at 25°C compared to 104lm for the main part, representing a 7% reduction in luminous flux. The substitute achieves 98 lm/W efficiency versus 87 lm/W for the main part.

Mechanical Compatibility: Both parts share identical physical dimensions (5.00mm x 5.00mm), height (1.48mm), and thermal resistance (5°C/W). The substitute features an Exposed Pad variant of the 2-SMD Gull Wing package, which may provide improved thermal performance in applications requiring enhanced heat dissipation.

Frequently Asked Questions (FAQ)

Q: Can MX6AWT-A1-R250-000BF6 be used as a direct drop-in replacement for MX6SWT-H1-R250-000CF6?

A: No. While both parts share identical physical dimensions and thermal characteristics, the substitute operates at 3.3V forward voltage compared to the main part's 20V specification. Direct substitution without circuit modification will result in component failure or malfunction. Power supply and current-limiting circuitry must be redesigned to accommodate the substitute's electrical requirements.

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

A: Substitution eligibility is based on: color and correlated color temperature (3700K warm white), CRI (80), viewing angle (120°), package type (2-SMD Gull Wing), physical dimensions (5.00mm x 5.00mm), height (1.48mm), and thermal resistance (5°C/W). Electrical parameters (voltage and current) differ significantly and require circuit-level evaluation.

Q: How does the Exposed Pad variant affect thermal performance?

A: The substitute part features a 2-SMD Gull Wing Exposed Pad package variant. The exposed pad provides an additional thermal path to the PCB, potentially improving heat dissipation compared to standard Gull Wing packages. Applications requiring enhanced thermal management may benefit from this design feature.

Q: What is the impact of the 7% flux reduction in the substitute part?

A: The substitute delivers 97lm at 25°C compared to 104lm for the main part. This 7% reduction in luminous flux must be evaluated against application-specific brightness requirements. The substitute's superior efficiency (98 lm/W versus 87 lm/W) may offset the flux reduction in power-constrained applications.

Q: Are there packaging differences between the main part and substitute?

A: Both parts use 2-SMD Gull Wing packages with identical physical dimensions. The main part is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format. The substitute features an Exposed Pad variant, which is a design enhancement rather than a compatibility issue.

Q: What compliance certifications apply to the substitute part?

A: The substitute part is RoHS Compliant and maintains REACH Unaffected status. Both parts carry EAR99 ECCN classification and HTSUS code 8541.41.0000. The substitute's RoHS compliance provides regulatory advantage for applications subject to RoHS requirements.
