Key Parameters

Substitute Part Grouping Explanation

The MX3SWT-A1-0000-000BE6 has one identified substitute: MX6AWT-A1-0000-000BA6. Substitution eligibility is determined by the following parameters:

• Color and correlated color temperature (CCT): Both parts are warm white at 3500K
• Luminous flux output: Both deliver 97 lumens at their respective test currents
• Color Rendering Index (CRI): Both maintain CRI of 80 (Typ)
• Viewing angle: Both provide 120° viewing angle
• Package and case type: Both use 2-SMD, Gull Wing Exposed Pad configuration
• Physical dimensions: Both measure 5.00 mm × 5.00 mm with 1.48 mm seated height
• Mounting type: Both are surface mount components

The substitute part operates at different electrical parameters (3.3V forward voltage, 300 mA test current) and has improved thermal characteristics (5°C/W vs. 11°C/W), but maintains functional equivalence in optical output and form factor.

Parameter Comparison

Engineering Selection Recommendations

The MX6AWT-A1-0000-000BA6 is the designated substitute for the obsolete MX3SWT-A1-0000-000BE6. Selection of the substitute part is supported by the following factors:

• Active product status: The MX6AWT remains in active production, ensuring long-term availability and supply chain continuity
• RoHS compliance: The substitute meets RoHS requirements, whereas compliance status for the original part is not specified
• Equivalent optical performance: Both parts deliver identical luminous flux (97 lm) and color characteristics (3500K, CRI 80)
• Identical form factor and mounting: Both components use the same 2-SMD package, physical dimensions, and surface mount configuration, enabling direct PCB compatibility
• Improved thermal performance: The substitute offers superior thermal management (5°C/W vs. 11°C/W), reducing thermal stress in applications

Circuit design modifications are required due to the different electrical operating parameters. The substitute operates at 3.3V forward voltage and 300 mA test current, compared to the original 10.7V and 115 mA. Power supply and current-limiting circuitry must be redesigned accordingly.

Frequently Asked Questions (FAQ)

Q: Can the MX6AWT-A1-0000-000BA6 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BE6?

A: The MX6AWT can replace the MX3SWT in terms of physical form factor and optical output. However, circuit modifications are mandatory. The substitute requires a 3.3V power supply and 300 mA current source, whereas the original part operated at 10.7V and 115 mA. Existing current-limiting resistors and power supply configurations must be redesigned.

Q: Are there any differences in package handling or moisture sensitivity?

A: Both parts share identical moisture sensitivity specifications (MSL 2A, 4 Weeks) and use the same 2-SMD, Gull Wing Exposed Pad package. Storage and handling procedures remain unchanged.

Q: What is the impact of the different thermal resistance values?

A: The substitute part has lower thermal resistance (5°C/W vs. 11°C/W), meaning it dissipates heat more efficiently. This improvement reduces junction temperature rise during operation, potentially extending component life and improving reliability in thermally constrained applications.

Q: Does the substitute part meet current regulatory requirements?

A: The MX6AWT-A1-0000-000BA6 is RoHS compliant and REACH unaffected, meeting current regulatory standards. The original MX3SWT part is obsolete, and its compliance status is not fully specified.

Q: Are the luminous flux outputs truly equivalent?

A: Both parts deliver 97 lumens at their respective test currents (115 mA for the original, 300 mA for the substitute). The optical output is equivalent. However, the substitute achieves higher efficiency (98 lm/W vs. 79 lm/W) due to its lower operating voltage.
