MX6SWT-H1-R250-000BA8 Equivalent & Substitute Parts

Part Overview

The MX6SWT-H1-R250-000BA8 is an XLamp® MX-6S warm white LED (3000K) designed for surface mount applications requiring high color rendering index (CRI 80) and efficient light output. This component operates at 20V forward voltage with a test current of 60mA, delivering 97 lumens at 25°C with an efficiency of 81 lm/W.

The product status is listed as Obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The MX-6S series has been superseded by the MX-6 series, which maintains compatibility across key electrical and mechanical parameters while offering improved performance characteristics and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-R250-000BA8 is based on the following criteria:

Matching Parameters (Required for Direct Substitution):

• Color and CCT: White, Warm 3000K
• Flux output range: 94–100 lm @ 25°C
• CRI: 80
• Viewing angle: 120°
• Package type: 2-SMD, Gull Wing configuration
• Physical dimensions: 5.00 × 5.00 mm footprint
• Height: 1.48 mm maximum seated height
• Thermal resistance: 5°C/W
• MSL rating: 2A (4 Weeks)

Allowable Variations:

• Forward voltage (Vf): May differ based on circuit design requirements
• Test current: May differ; substitute must operate within specified maximum current rating
• Lumens/Watt efficiency: May vary; substitute performance acceptable if flux output remains within specified range
• Product status: Active status preferred for long-term availability

The MX6AWT-H1-R250-000BA8 meets all matching parameters and represents the direct successor within the XLamp® product family.

Engineering Selection Recommendations

Primary Substitute: MX6AWT-H1-R250-000BA8

The MX6AWT-H1-R250-000BA8 is the direct functional equivalent and recommended substitute for the obsolete MX6SWT-H1-R250-000BA8. Selection is based on the following engineering factors:

1. Product Status: The substitute maintains Active product status, ensuring long-term availability and manufacturing support compared to the Obsolete main part.

2. Optical Compatibility: Both parts deliver identical flux output (97 lm, 94–100 lm range) and CRI (80) at their respective test currents, maintaining color temperature (3000K) and viewing angle (120°) specifications.

3. Mechanical Compatibility: Identical footprint (5.00 × 5.00 mm), height (1.48 mm), and thermal resistance (5°C/W) ensure direct PCB layout compatibility without redesign.

4. Compliance: The substitute carries RoHS Compliant certification and maintains REACH Unaffected status, meeting current regulatory requirements.

5. Electrical Differences: The substitute operates at 3.3V forward voltage with 300mA test current, compared to 20V/60mA for the main part. Circuit design must accommodate this voltage and current difference. Maximum current rating increases from 175mA to 1A, providing greater operational headroom.

6. Performance Enhancement: Lumens/Watt efficiency improves from 81 lm/W to 98 lm/W, reducing power consumption for equivalent light output.

7. Packaging: Standard Tape & Reel (TR) packaging supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-R250-000BA8 be used as a direct drop-in replacement for the MX6SWT-H1-R250-000BA8?

A: Mechanical and optical compatibility is direct; however, electrical circuit redesign is required. The substitute operates at 3.3V forward voltage versus 20V for the original part. Current-limiting resistors and power supply specifications must be recalculated for the new voltage and current parameters.

Q: What are the key differences between the MX-6S and MX-6 series?

A: The MX-6 series (represented by MX6AWT) is the successor to the MX-6S series (MX6SWT). Both maintain identical optical output, CRI, viewing angle, and physical dimensions. The MX-6 series features lower forward voltage (3.3V vs. 20V), higher test current (300mA vs. 60mA), improved efficiency (98 lm/W vs. 81 lm/W), and Active product status versus Obsolete.

Q: Are the package configurations compatible?

A: Both parts use 2-SMD, Gull Wing surface mount packages with identical 5.00 × 5.00 mm footprints and 1.48 mm maximum height. The substitute includes an exposed pad for improved thermal management. PCB layout compatibility is maintained without modification.

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

A: The exposed pad on the MX6AWT-H1-R250-000BA8 provides enhanced thermal dissipation. Both parts maintain identical thermal resistance (5°C/W), so thermal performance is equivalent. The exposed pad may be left unconnected or connected to ground per thermal design requirements.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The MX6AWT-H1-R250-000BA8 carries RoHS Compliant certification and maintains REACH Unaffected status. The original MX6SWT-H1-R250-000BA8 does not specify RoHS compliance, making the substitute preferable for applications requiring regulatory compliance documentation.

Q: What is the maximum current rating for each part?

A: The MX6SWT-H1-R250-000BA8 has a maximum current rating of 175mA. The MX6AWT-H1-R250-000BA8 has a maximum current rating of 1A. Both parts are tested at lower currents (60mA and 300mA respectively) to establish flux and efficiency specifications.

Q: Are there inventory considerations for substitution?

A: The MX6SWT-H1-R250-000BA8 is listed as Obsolete with 813 pieces in stock. The MX6AWT-H1-R250-000BA8 is Active with 900 pieces in stock, providing better long-term procurement assurance.
