Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD22105AR is determined by strict equivalence across the following critical parameters:

• Output Topology: Open collector, active high configuration
• Switching Capability: Programmable trip temperature
• Thermal Range: Operating temperature -40°C ~ 150°C
• Electrical Specifications: Supply voltage 2.7 V ~ 7 V, maximum output current 10mA
• Package Compatibility: 8-SOIC surface mount form factor
• Accuracy: ±2°C thermal accuracy
• Manufacturer Lineage: Analog Devices Inc. product family

The AD22105ARZ qualifies as a direct substitute based on identical electrical characteristics, thermal specifications, package geometry, and functional output behavior. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The AD22105ARZ is the appropriate selection for new designs and ongoing production support. This part maintains identical electrical and thermal performance specifications while offering active product status and current compliance certifications (ROHS3, REACH). The AD22105AR, classified as obsolete, should be replaced in active applications to ensure long-term supply chain continuity and regulatory compliance alignment.

For legacy systems currently utilizing AD22105AR, direct substitution with AD22105ARZ requires no circuit modifications, as all functional parameters and package geometry remain equivalent. Packaging format differs (tube versus unspecified for the original), but this does not affect electrical performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can AD22105ARZ directly replace AD22105AR in existing circuits?

A: Yes. Both components share identical electrical specifications, thermal accuracy, output topology, supply voltage range, and 8-SOIC package geometry. No circuit redesign is required.

Q: What is the primary reason to substitute AD22105AR?

A: The AD22105AR is obsolete. The AD22105ARZ provides functional equivalence with active product status and current regulatory compliance certifications.

Q: Are there differences in package dimensions between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) package. PCB footprints and assembly processes remain identical.

Q: Does the AD22105ARZ meet current environmental compliance standards?

A: Yes. The AD22105ARZ is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What are the critical parameters for substitution compatibility?

A: Open collector output topology, active high configuration, programmable switching temperature, ±2°C accuracy, 2.7 V ~ 7 V supply voltage, 10mA maximum output current, and -40°C ~ 150°C operating temperature range must all remain constant for functional equivalence.
