Key Parameters

Substitute Part Grouping Explanation

Substitution for the AD7306JR is determined by strict equivalence across the following critical parameters:

• Protocol Support: RS232 and RS422 dual-protocol capability
• Driver/Receiver Configuration: 3 drivers and 3 receivers
• Duplex Mode: Full-duplex operation
• Package Type: 24-SOIC surface mount package with identical physical dimensions (0.295", 7.50mm Width)
• Electrical Specifications: Voltage supply range (4.75V ~ 5.25V), operating temperature range (0°C ~ 70°C), and receiver hysteresis (70 mV)
• Moisture Sensitivity: MSL 1 (Unlimited)

The AD7306JRZ qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The AD7306JRZ is the direct substitute for the AD7306JR. Both components are electrically and mechanically identical across all specified parameters. The AD7306JRZ is preferred for new designs and ongoing procurement due to its active product status. The AD7306JRZ carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in industrial and commercial applications.

For systems currently using the AD7306JR, transition to the AD7306JRZ requires no circuit modifications, as pin configuration, electrical characteristics, and package dimensions are identical. The tube packaging format of the AD7306JRZ is standard for active production components.

Frequently Asked Questions (FAQ)

Q: Can the AD7306JRZ be used as a direct replacement for the AD7306JR in existing designs?

A: Yes. The AD7306JRZ is electrically and mechanically identical to the AD7306JR. No circuit modifications are required. Both components feature the same 24-SOIC package, identical pin configuration, and matching electrical specifications across voltage supply, operating temperature, and receiver hysteresis parameters.

Q: What is the primary difference between the AD7306JR and AD7306JRZ?

A: The AD7306JR is classified as obsolete, while the AD7306JRZ is active. The AD7306JRZ is supplied in tube packaging and includes ROHS3 compliance and REACH unaffected certifications. Functionally and electrically, both parts are equivalent.

Q: Are there any package or mounting considerations when substituting the AD7306JRZ for the AD7306JR?

A: No. Both components use the identical 24-SOIC surface mount package with 0.295" width (7.50mm). PCB footprints, solder reflow profiles, and assembly processes remain unchanged.

Q: What protocols does the AD7306JRZ support?

A: The AD7306JRZ supports both RS232 and RS422 serial communication protocols with full-duplex operation. The 3/3 driver/receiver configuration provides three independent channels for each protocol.

Q: Is the AD7306JRZ suitable for new product designs?

A: Yes. The AD7306JRZ is an active component with current manufacturing support. It meets ROHS3 and REACH regulatory requirements, making it appropriate for new designs and long-term production.
