AD7306AR Equivalent & Substitute Parts

Part Overview

The AD7306AR is a 3/3 transceiver IC designed for full-duplex RS232 and RS422 serial communication applications. Manufactured by Analog Devices Inc., this component integrates three drivers and three receivers in a 24-SOIC surface mount package. The AD7306AR is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Substitute Part Grouping Explanation

Substitution of the AD7306AR is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: Both main and substitute parts must support RS232 and RS422 protocols
• Channel Configuration: Identical 3/3 driver/receiver configuration required
• Duplex Operation: Full-duplex capability must be maintained
• Electrical Specifications: Receiver hysteresis (70 mV), supply voltage range (4.75V ~ 5.25V), and operating temperature range (-40°C ~ 85°C) must match exactly
• Package Compatibility: 24-SOIC surface mount package with identical physical dimensions (0.295", 7.50mm Width)
• Moisture Sensitivity: MSL rating of 1 (Unlimited) must be maintained

The AD7306ARZ qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction is product status: AD7306ARZ is active and available, whereas AD7306AR is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The AD7306ARZ is the direct equivalent substitute for the AD7306AR. Selection of AD7306ARZ is supported by:

• Electrical Equivalence: All functional and electrical parameters are identical
• Package Compatibility: Identical 24-SOIC package ensures direct PCB compatibility without layout modifications
• Product Status: AD7306ARZ maintains active product status with current manufacturing support, addressing the obsolescence of AD7306AR
• Compliance: AD7306ARZ carries RoHS3 compliance and REACH unaffected status, meeting modern regulatory requirements
• Availability: AD7306ARZ demonstrates significantly higher inventory availability (25,100 pcs vs. 2,400 pcs), ensuring supply chain reliability

For applications currently using AD7306AR, direct replacement with AD7306ARZ requires no circuit modifications, firmware changes, or design alterations.

Frequently Asked Questions (FAQ)

Q: Can AD7306ARZ be used as a direct replacement for AD7306AR in existing designs?

A: Yes. AD7306ARZ is electrically and mechanically equivalent to AD7306AR. All electrical parameters, package dimensions, and functional specifications are identical. Direct PCB substitution is possible without design modifications.

Q: What is the primary reason for substituting AD7306AR?

A: AD7306AR is classified as obsolete. AD7306ARZ is the active equivalent from the same manufacturer, ensuring continued availability and manufacturing support.

Q: Are there any packaging differences between AD7306AR and AD7306ARZ?

A: No. Both parts use the 24-SOIC package with identical physical dimensions (0.295", 7.50mm Width). The only packaging difference is that AD7306ARZ is supplied in tube packaging, whereas AD7306AR packaging type was not specified.

Q: Do the parts have different compliance certifications?

A: AD7306ARZ includes RoHS3 compliance and REACH unaffected status. These certifications were not specified for AD7306AR. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: protocol support (RS232/RS422), channel configuration (3/3), duplex mode (full), receiver hysteresis (70 mV), supply voltage range (4.75V ~ 5.25V), operating temperature range (-40°C ~ 85°C), and package type (24-SOIC).
