Substitute Part Grouping Explanation

Substitution of the MX6SWT-H1-R250-000DF6 is based on the following criteria:

Mandatory Matching Parameters:

• Color and CCT: White, Warm 3700K
• CRI: 80
• Viewing Angle: 120°
• Mounting Type: Surface Mount
• Package Footprint: 5.00 mm × 5.00 mm
• Height: 1.48 mm maximum
• Thermal Resistance: 5°C/W
• MSL Rating: 2A (4 Weeks)
• REACH Compliance: REACH Unaffected

Allowable Variation Parameters:

• Forward Voltage (Vf): May differ based on series evolution
• Test Current: May differ based on series optimization
• Maximum Current: May differ based on series design
• Lumens/Watt: May improve in newer series
• Flux Output: May vary within acceptable range for warm white 3700K LEDs
• Package Variant: Gull Wing or Gull Wing Exposed Pad acceptable
• Product Status: Active status preferred for new designs

The MX6AWT-H1-0000-000BF6 qualifies as a direct substitute based on matching all mandatory parameters while offering improved electrical efficiency and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-H1-0000-000BF6 is the qualified substitute for the obsolete MX6SWT-H1-R250-000DF6. Selection is based on:

• Product Status: The substitute maintains active product status, ensuring long-term availability and supply chain continuity.
• Compliance: Both parts maintain REACH Unaffected status. The substitute adds RoHS Compliance certification.
• Electrical Compatibility: While forward voltage and test current differ significantly (20V/60mA vs. 3.3V/300mA), both parts deliver warm white 3700K output with identical CRI and viewing angle specifications. Circuit design must accommodate the lower voltage and higher current characteristics of the MX-6 series.
• Thermal and Mechanical Compatibility: Identical footprint, height, and thermal resistance ensure direct PCB layout compatibility.
• Packaging: The substitute is supplied in Tape & Reel format, standard for production environments, versus bulk packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-H1-0000-000BF6 be used as a direct drop-in replacement for the MX6SWT-H1-R250-000DF6?

A: Mechanical and thermal compatibility is direct. Electrical circuit redesign is required due to the significant difference in forward voltage (20V vs. 3.3V) and test current (60mA vs. 300mA). PCB layout remains compatible due to identical footprint and height specifications.

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

A: The MX-6 series represents a product line evolution with improved efficiency (98 lm/W vs. 93 lm/W), lower forward voltage (3.3V vs. 20V), and higher maximum current rating (1A vs. 175mA). Both maintain identical color temperature, CRI, viewing angle, and thermal characteristics.

Q: Are there any compliance or certification differences?

A: The substitute part adds RoHS Compliance certification. Both parts maintain REACH Unaffected status and identical MSL ratings. The substitute's active product status ensures ongoing compliance updates and supply availability.

Q: Does the package variant (Gull Wing vs. Gull Wing Exposed Pad) affect compatibility?

A: The exposed pad in the MX-6 variant improves thermal performance in high-current applications. PCB layout compatibility is maintained; thermal pad connection is optional but recommended for optimal heat dissipation at higher current levels (up to 1A).

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

A: The MX6SWT outputs 111 lm at 60mA test current, while the MX6AWT outputs 97 lm at 300mA test current. Direct lumen comparison requires normalization to identical test conditions; the MX-6 series demonstrates superior lumens-per-watt efficiency.
