Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000BB3 is based on the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 2-SMD, Gull Wing Exposed Pad configuration with identical 5.00 mm × 5.00 mm footprint and 1.48 mm maximum seated height to ensure PCB layout compatibility.
• Mounting Type: Surface mount technology must be maintained.
• Color: White LED output is required.
• Viewing Angle: 120° viewing angle is preserved across substitute options.
• Thermal Characteristics: Thermal resistance of 11°C/W ensures equivalent thermal management.
• Moisture Sensitivity: MSL 2A classification maintains consistent handling and storage requirements.

The MX3AWT-A1-0000-000CB3 qualifies as a substitute based on matching package geometry, mounting type, color, viewing angle, thermal resistance, and moisture sensitivity. However, this substitute operates at significantly different electrical parameters (3.7V forward voltage, 350 mA test current, 104 lm flux) compared to the original part, requiring circuit redesign and validation.

Engineering Selection Recommendations

The MX3AWT-A1-0000-000CB3 is the identified substitute for the obsolete MX3SWT-A1-0000-000BB3. Selection of this substitute is supported by:

• Active Product Status: The MX3AWT-A1-0000-000CB3 maintains Active product status, ensuring ongoing availability and manufacturer support.
• RoHS Compliance: The substitute is RoHS Compliant, meeting current regulatory requirements for electronic components.
• Regulatory Alignment: Both parts maintain REACH Unaffected status and identical ECCN and HTSUS classifications.
• Physical Compatibility: Identical package footprint, height, and thermal resistance enable direct PCB layout reuse.

Critical consideration: The substitute operates at substantially different electrical parameters. The MX3AWT-A1-0000-000CB3 requires 3.7V forward voltage and 350 mA test current compared to the original 10.7V and 115 mA. Circuit redesign of power supply, current limiting, and thermal management is mandatory before implementation.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000CB3 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000BB3?

A: No. While both parts share identical package geometry, footprint, and thermal characteristics, the electrical parameters differ significantly. The substitute operates at 3.7V forward voltage and 350 mA test current versus the original 10.7V and 115 mA. Circuit redesign is required.

Q: Are the PCB footprints identical between these two parts?

A: Yes. Both parts use the 2-SMD, Gull Wing Exposed Pad package with 5.00 mm × 5.00 mm dimensions and 1.48 mm maximum seated height. PCB layout can be reused without modification.

Q: What are the key differences in electrical performance?

A: The MX3AWT-A1-0000-000CB3 operates at lower forward voltage (3.7V vs. 10.7V) and higher test current (350 mA vs. 115 mA). Luminous flux is slightly higher (104 lm vs. 97 lm), and lumens-per-watt efficiency is comparable (80 lm/W vs. 79 lm/W).

Q: Does the substitute meet current regulatory requirements?

A: Yes. The MX3AWT-A1-0000-000CB3 is RoHS Compliant and maintains REACH Unaffected status, meeting current regulatory standards. The original part's regulatory status is not specified.

Q: What is the impact of the different packaging format?

A: The original part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly processes but does not impact component functionality or performance.

Q: Are the thermal characteristics equivalent?

A: Yes. Both parts have identical thermal resistance of 11°C/W and MSL 2A (4 Weeks) moisture sensitivity classification, ensuring equivalent thermal management and handling requirements.
