AD7306JN Equivalent & Substitute Parts

Part Overview

The AD7306JN is a full-duplex RS232/RS422 transceiver IC manufactured by Analog Devices Inc., configured with 3 drivers and 3 receivers in a 24-pin DIP package. This component is classified as obsolete, indicating that direct procurement from primary sources may be limited. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring RS232/RS422 interface functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD7306JN is determined by strict equivalence across the following critical parameters:

• Protocol support (RS232 and RS422 dual-protocol capability)
• Driver and receiver configuration (3/3 topology)
• Full-duplex operation
• Receiver hysteresis specification (70 mV)
• Supply voltage range (4.75V ~ 5.25V)
• Operating temperature range (0°C ~ 70°C)
• Package and pinout compatibility (24-DIP, 0.300" pitch)
• Through-hole mounting requirement

The AD7306JNZ meets all these criteria and is therefore a direct functional equivalent. The primary distinction between these parts is product status and packaging format, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The AD7306JNZ is the direct substitute for the AD7306JN. Both parts share identical electrical specifications and package geometry, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The AD7306JNZ is preferred for new designs and ongoing production due to its active product status. This part carries ROHS3 compliance and REACH unaffected certification, meeting current regulatory requirements for electronic components in regulated markets.

The AD7306JN, classified as obsolete, should be replaced with the AD7306JNZ in procurement activities. The transition requires no circuit modifications, PCB redesign, or firmware changes.

Frequently Asked Questions (FAQ)

Q: Can the AD7306JNZ be used as a direct replacement for the AD7306JN?

A: Yes. The AD7306JNZ is electrically and mechanically identical to the AD7306JN. Both parts feature the same 3/3 driver/receiver configuration, RS232/RS422 protocol support, 70 mV receiver hysteresis, 4.75V ~ 5.25V supply voltage range, 0°C ~ 70°C operating temperature, and 24-DIP package. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The AD7306JNZ is the active production variant, while the AD7306JN is obsolete. The AD7306JNZ includes ROHS3 compliance and REACH unaffected certification. Packaging format differs (tube versus unspecified), but electrical performance and pinout are identical.

Q: Are there any compatibility concerns with the 24-DIP package?

A: No. Both parts use the same 24-DIP (0.300", 7.62mm) package with through-hole mounting. PCB footprints and assembly processes remain unchanged.

Q: Does the AD7306JNZ meet current regulatory standards?

A: Yes. The AD7306JNZ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical specifications, pinout, and package dimensions are identical. Existing designs using the AD7306JN can incorporate the AD7306JNZ without modification.
