Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD590JR is determined by strict equivalence across the following critical parameters:

• Sensor type classification (Analog, Local)
• Sensing temperature range (-40°C ~ 125°C)
• Output type (Analog Current)
• Supply voltage range (4V ~ 30V)
• Accuracy specification (±5°C @ 25°C)
• Package type (8-SOIC with identical physical dimensions)
• Mounting configuration (Surface Mount)

The AD590JRZ qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between these parts is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The AD590JRZ is the direct functional equivalent of the AD590JR for all electrical and mechanical applications. Selection of AD590JRZ is appropriate for the following conditions:

• Replacement of obsolete AD590JR inventory in existing designs
• New designs requiring AD590 series analog temperature sensor functionality
• Applications requiring active product status and current manufacturer support
• Systems requiring ROHS3 compliance and REACH regulatory alignment

The AD590JRZ maintains identical electrical performance, pinout configuration, and package dimensions, enabling direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can AD590JRZ replace AD590JR in existing circuit designs?

A: Yes. The AD590JRZ provides identical electrical characteristics, pinout, and package dimensions. Direct substitution is possible without circuit modification.

Q: What is the primary reason to transition from AD590JR to AD590JRZ?

A: The AD590JR is classified as obsolete. The AD590JRZ is the active equivalent part, ensuring continued availability, manufacturer support, and compliance with current regulatory standards.

Q: Are there differences in temperature measurement accuracy between these parts?

A: No. Both parts specify ±5°C accuracy at 25°C test condition across the -40°C to 125°C sensing range.

Q: Does packaging format affect electrical performance?

A: No. The tube packaging of AD590JRZ is a distribution format only. Electrical specifications and device performance remain identical to the standard packaging of AD590JR.

Q: Are there compliance differences between AD590JR and AD590JRZ?

A: The AD590JRZ carries ROHS3 compliance and REACH unaffected status. These certifications reflect current regulatory requirements and are recommended for new designs and long-term system support.

Q: What supply voltage range is required for these temperature sensors?

A: Both parts operate with a supply voltage range of 4V to 30V, providing flexibility across diverse application requirements.

Q: Is the 8-SOIC package suitable for high-density PCB layouts?

A: Yes. The 8-SOIC package with 0.154" (3.90mm) width is a standard surface-mount format compatible with automated assembly processes and modern PCB design practices.
