Substitute Part Grouping Explanation

Substitution of the AD8519ARZ is determined by functional equivalence across the following critical parameters:

Functional Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply Span: 2.7 V (Min) to 12 V (Max)
• Operating Temperature Range: -40°C to 125°C

Performance Parameters: Substitute parts must maintain electrical performance within the operational envelope defined by slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current specifications.

The OP162GSZ qualifies as a direct substitute based on matching all functional compatibility criteria and maintaining compatible electrical performance characteristics within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The AD8519ARZ is classified as obsolete, with no ongoing production. The OP162GSZ is an active product from the same manufacturer, ensuring continued availability and supply chain support for new procurement requirements.

Compliance and Certifications: The OP162GSZ carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to environmental and hazardous substance restrictions. Both devices share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Electrical Performance: The OP162GSZ demonstrates enhanced electrical characteristics across multiple parameters: slew rate increased to 13 V/µs (versus 2.9 V/µs), gain bandwidth product increased to 15 MHz (versus 8 MHz), input offset voltage reduced to 25 µV (versus 600 µV), and output current capability increased to 30 mA (versus 25 mA). These improvements maintain backward compatibility while providing superior performance margins.

Package and Thermal Compatibility: Both devices utilize identical 8-SOIC surface mount packaging with matching physical dimensions and thermal characteristics, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the OP162GSZ be used as a direct replacement for the AD8519ARZ in existing designs?

A: Yes. The OP162GSZ is functionally equivalent to the AD8519ARZ across all critical parameters: identical package type (8-SOIC), matching supply voltage range (2.7 V to 12 V), identical operating temperature range (-40°C to 125°C), and equivalent circuit topology (single general-purpose rail-to-rail amplifier). Pin-for-pin compatibility is maintained.

Q: What are the key differences between these two parts?

A: The OP162GSZ provides enhanced electrical performance: 4.5× higher slew rate (13 V/µs versus 2.9 V/µs), 1.875× higher gain bandwidth product (15 MHz versus 8 MHz), 24× lower input offset voltage (25 µV versus 600 µV), and 20% higher output current capability (30 mA versus 25 mA). Supply current is marginally higher (650 µA versus 600 µA). The OP162GSZ is an active product, whereas the AD8519ARZ is obsolete.

Q: Are there any circuit design modifications required when substituting the OP162GSZ for the AD8519ARZ?

A: No circuit design modifications are required. The OP162GSZ maintains electrical compatibility within the specified operating envelope. The enhanced performance characteristics of the OP162GSZ are backward compatible with designs optimized for the AD8519ARZ.

Q: What is the packaging difference between these parts?

A: Both parts are supplied in 8-SOIC surface mount packages with identical physical dimensions (0.154" width, 3.90mm). The AD8519ARZ packaging type is not specified in available data. The OP162GSZ is supplied in tube packaging. No board-level modifications are necessary for substitution.

Q: Are there regulatory or compliance considerations for this substitution?
