MX6SWT-H1-R250-000CE8 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-R250-000CE8 is an XLamp® MX-6S warm white LED (2700K) designed for surface mount applications requiring 20V forward voltage operation at 60mA test current. This component delivers 104lm at 25°C with a color rendering index of 80 and 120° viewing angle in a compact 5.00mm x 5.00mm 2-SMD gull wing package.

The product status is obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity. Substitute parts must maintain compatibility across electrical performance, thermal characteristics, and mechanical form factor while accounting for operational voltage and current differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-R250-000CE8 is based on the following criteria derived from the provided parameters:

Mandatory Compatibility Parameters:

• Color and CCT: White, Warm 2700K (exact match required)
• CRI: 80 (minimum acceptable)
• Viewing Angle: 120° (mechanical and optical compatibility)
• Package Type: 2-SMD, Gull Wing configuration
• Physical Dimensions: 5.00mm x 5.00mm footprint
• Height - Seated (Max): 1.48mm
• Thermal Resistance: 5°C/W
• Moisture Sensitivity Level: 2A (4 Weeks)

Electrical Performance Parameters (allowable variation):

• Forward Voltage (Vf): May differ due to series configuration differences
• Test Current: May differ based on LED architecture
• Flux Output: Comparable lumen output at respective test currents
• Lumens/Watt: Efficiency metric dependent on voltage/current configuration
• Maximum Current Rating: Must accommodate circuit design requirements

The MX6AWT-A1-R250-000BE8 qualifies as a substitute based on matching color temperature, CRI, viewing angle, package configuration, and physical dimensions. The primary electrical differences (3.3V vs. 20V forward voltage, 300mA vs. 60mA test current) reflect the architectural transition from the MX-6S to the MX-6 series and require circuit redesign for proper operation.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-R250-000BE8 is the designated substitute for the obsolete MX6SWT-H1-R250-000CE8 based on product status and compliance considerations.

Status Justification: The MX6SWT-H1-R250-000CE8 is obsolete, while the MX6AWT-A1-R250-000BE8 maintains active product status, ensuring ongoing availability and manufacturing support.

Compliance Advantage: The MX6AWT-A1-R250-000BE8 is RoHS Compliant, providing regulatory alignment for applications subject to RoHS requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Electrical Redesign Requirement: Direct pin-for-pin substitution is not possible due to fundamental voltage and current differences (20V/60mA vs. 3.3V/300mA). Circuit topology and current-limiting resistor values must be recalculated to accommodate the MX-6 series electrical characteristics.

Optical and Mechanical Compatibility: Both parts maintain identical color temperature (2700K), CRI (80), viewing angle (120°), footprint (5.00mm x 5.00mm), and thermal resistance (5°C/W), ensuring optical performance and thermal management compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-R250-000BE8 be used as a direct replacement without circuit modification?

A: No. The MX6AWT-A1-R250-000BE8 operates at 3.3V with 300mA test current, compared to the MX6SWT-H1-R250-000CE8 at 20V with 60mA test current. Circuit redesign is required, including recalculation of current-limiting resistors and power supply voltage compatibility.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts share identical footprint dimensions (5.00mm x 5.00mm) and maximum seated height (1.48mm), enabling PCB layout compatibility without modification.

Q: What is the difference between the standard gull wing package and the exposed pad variant?

A: The MX6AWT-A1-R250-000BE8 features an exposed pad configuration, which provides enhanced thermal dissipation compared to the standard gull wing package. Both maintain the same 5°C/W thermal resistance rating.

Q: Do both parts meet the same moisture sensitivity requirements?

A: Yes. Both parts are rated MSL 2A (4 Weeks), requiring identical moisture control and storage protocols during handling and assembly.

Q: Is the color rendering index identical between the two parts?

A: Yes. Both parts maintain CRI 80, ensuring equivalent color reproduction characteristics for warm white 2700K applications.

Q: What is the flux output difference between the two parts?

A: The MX6SWT-H1-R250-000CE8 produces 104lm at 60mA, while the MX6AWT-A1-R250-000BE8 produces 97lm at 300mA. The flux difference reflects the different test current conditions and LED architecture rather than optical performance degradation.
