Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MX3SWT-A1-0000-000AB8 is determined by the following critical parameters:

• Mechanical Compatibility: Package type (2-SMD, Gull Wing Exposed Pad), footprint dimensions (5.00mm x 5.00mm), and height (1.48mm maximum)
• Optical Compatibility: Color (White) and viewing angle (120°)
• Thermal Compatibility: Thermal resistance (11°C/W)
• Environmental Compliance: Moisture sensitivity level (2A, 4 Weeks) and REACH status

The identified substitute part MX3AWT-A1-0000-000BB1 shares identical mechanical, optical, and thermal characteristics. However, this substitute operates at significantly different electrical parameters: 3.7V forward voltage and 350mA test current, compared to the original part's 10.7V and 115mA. This electrical difference requires circuit redesign and is not a direct pin-compatible replacement.

Engineering Selection Recommendations

The MX3AWT-A1-0000-000BB1 is the identified substitute for the obsolete MX3SWT-A1-0000-000AB8. Selection of this substitute requires the following considerations:

Electrical Redesign Required: The substitute operates at 3.7V forward voltage versus the original 10.7V. This necessitates modification of the power supply circuit and current-limiting resistor values. The substitute draws 350mA at test current compared to 115mA for the original part.

Mechanical and Optical Compatibility: Both parts share identical package geometry (2-SMD, Gull Wing Exposed Pad), footprint dimensions (5.00mm x 5.00mm), height (1.48mm), thermal resistance (11°C/W), and viewing angle (120°). PCB layout and thermal management remain unchanged.

Compliance Status: The substitute is RoHS Compliant and carries Active product status, ensuring long-term availability and supply chain continuity. Both parts maintain REACH Unaffected status and identical moisture sensitivity levels.

Luminous Output: The substitute delivers 97 lumens at 350mA test current, compared to 91 lumens at 115mA for the original part. Efficiency is comparable at 75 lm/W versus 74 lm/W.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BB1 be used as a direct replacement without circuit modification?

A: No. The substitute operates at 3.7V forward voltage compared to the original 10.7V. Direct substitution without circuit redesign will result in component failure or inadequate operation. Power supply voltage and current-limiting resistor values must be recalculated for the substitute's electrical specifications.

Q: Are the physical footprints identical between the main part and substitute?

A: Yes. Both parts use the 2-SMD, Gull Wing Exposed Pad package with identical dimensions (5.00mm x 5.00mm) and maximum seated height (1.48mm). PCB layout and solder pad geometry remain unchanged.

Q: What is the primary reason for substitution?

A: The MX3SWT-A1-0000-000AB8 is classified as obsolete. The MX3AWT-A1-0000-000BB1 is an active product from the same manufacturer, ensuring continued availability and supply chain support.

Q: How do the thermal characteristics compare?

A: Both parts have identical thermal resistance of 11°C/W. Thermal management design remains unchanged between the original and substitute.

Q: Are there compliance differences between the two parts?

A: The substitute is RoHS Compliant, while the original part's RoHS status is not specified. Both maintain REACH Unaffected status and identical moisture sensitivity levels (2A, 4 Weeks).

Q: What is the luminous output difference?

A: The substitute produces 97 lumens at 350mA test current, compared to 91 lumens at 115mA for the original part. The substitute delivers approximately 6 lumens higher output at its specified test current.
