MAX3293AUT Equivalent & Substitute Parts

Part Overview

The MAX3293AUT is a 1/0 Driver IC for RS422 and RS485 serial communication interfaces, manufactured by Analog Devices Inc./Maxim Integrated. This component operates at a data rate of 250kbps with a supply voltage range of 3.14V to 3.47V and is housed in a SOT-23-6 surface mount package. The MAX3293AUT is currently classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the MAX3293AUT is determined by strict equivalence across the following critical parameters:

• Protocol compatibility: RS422 and RS485 serial communication standards
• Driver/Receiver configuration: 1 driver, 0 receivers
• Data rate capability: 250kbps minimum
• Supply voltage range: 3.14V to 3.47V
• Package type: SOT-23-6 surface mount
• Operating temperature range: -40°C to 125°C
• Electrical and mechanical pin compatibility

The MAX3293AUT+ meets all these criteria and is identified as a direct substitute. The primary distinction between the main part and its substitute is product status: the MAX3293AUT is obsolete, while the MAX3293AUT+ is active and currently in production.

Parameter Comparison

Engineering Selection Recommendations

The MAX3293AUT+ is the direct substitute for the MAX3293AUT. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, package configuration, and compliance certifications. The MAX3293AUT+ maintains ROHS3 compliance and carries an EAR99 ECCN classification, confirming its suitability for applications requiring the original MAX3293AUT.

For new designs and ongoing system support where the MAX3293AUT is no longer available, the MAX3293AUT+ provides functional and mechanical equivalence without design modification. The active product status of the MAX3293AUT+ ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MAX3293AUT+ be used as a direct replacement for the MAX3293AUT?

A: Yes. The MAX3293AUT+ is electrically and mechanically equivalent to the MAX3293AUT. Both components feature identical RS422/RS485 driver specifications, supply voltage range, data rate, operating temperature range, and SOT-23-6 package configuration. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The MAX3293AUT is classified as obsolete. The MAX3293AUT+ is the active equivalent from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited). The MAX3293AUT+ carries an EAR99 ECCN classification, confirming its regulatory status for distribution and use.

Q: Is the SOT-23-6 package identical between both parts?

A: Yes. Both the MAX3293AUT and MAX3293AUT+ use the SOT-23-6 surface mount package with identical pin configuration and mechanical dimensions, allowing direct PCB placement without layout modifications.

Q: What are the critical parameters for confirming substitution compatibility?

A: Substitution is valid when the following parameters match: RS422/RS485 protocol support, 1/0 driver/receiver configuration, 250kbps data rate capability, 3.14V to 3.47V supply voltage range, -40°C to 125°C operating temperature, and SOT-23-6 package type.
