Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP262GS is determined by electrical and mechanical compatibility across the following critical parameters:

Primary Substitution Criteria:

• Number of circuits: 2 channels
• Output type: Rail-to-rail configuration
• Package type: 8-SOIC surface mount
• Mounting footprint: 0.154" width (3.90mm)
• Supply voltage range: Minimum 2.7 V to maximum 12 V
• Operating temperature range: -40°C to 125°C

Direct Equivalent Classification: The OP262GSZ represents a direct equivalent, maintaining identical electrical specifications and performance characteristics while differing only in packaging format (tube versus unspecified packaging for the main part). This part is active in production status.

Similar Substitute Classification: The ALD2732SAL and ALD2732ASAL from Advanced Linear Devices Inc. are classified as similar substitutes. These parts share the same package type (8-SOIC), dual-channel configuration, and rail-to-rail output topology. However, they exhibit reduced electrical performance across multiple parameters: slew rate of 1.9 V/µs (versus 13 V/µs), gain bandwidth product of 1.5 MHz (versus 15 MHz), and restricted operating temperature range of 0°C to 70°C (versus -40°C to 125°C). The supply voltage range is also constrained to 4 V to 10 V. These differences require application-level evaluation for suitability.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (OP262GSZ): The OP262GSZ is the recommended direct replacement for the obsolete OP262GS. This part maintains complete electrical and mechanical compatibility with identical performance specifications across all measured parameters. The OP262GSZ is active in production status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment. Selection of OP262GSZ requires no circuit redesign or performance re-evaluation.

Similar Substitution (ALD2732SAL / ALD2732ASAL): The ALD2732SAL and ALD2732ASAL are suitable as similar substitutes only in applications where reduced performance specifications are acceptable. These parts are active in production and ROHS3 compliant. However, the following electrical constraints apply:

• Slew rate reduction from 13 V/µs to 1.9 V/µs limits high-frequency transient response
• Gain bandwidth product reduction from 15 MHz to 1.5 MHz restricts bandwidth-dependent applications
• Operating temperature range limitation to 0°C to 70°C excludes extended temperature applications
• Supply voltage range constraint to 4 V to 10 V eliminates low-voltage (2.7 V) operation
• Input offset voltage increase to 2 mV (ALD2732SAL) or 600 µV (ALD2732ASAL) versus 25 µV affects precision applications

Selection of ALD2732 variants requires application-level verification that reduced performance parameters do not compromise system functionality.

Frequently Asked Questions (FAQ)

Q: Can the OP262GSZ be used as a direct replacement for the OP262GS without circuit modification?

A: Yes. The OP262GSZ maintains identical electrical specifications, performance characteristics, and 8-SOIC package footprint. No circuit redesign is required. The only difference is packaging format (tube). Direct substitution is supported.

Q: What are the key differences between the OP262GS and the ALD2732 series?

A: The primary differences are slew rate (13 V/µs versus 1.9 V/µs), gain bandwidth product (15 MHz versus 1.5 MHz), operating temperature range (-40°C to 125°C versus 0°C to 70°C), and supply voltage range (2.7 V to 12 V versus 4 V to 10 V). The ALD2732 series exhibits lower performance across all dynamic parameters.

Q: Are the ALD2732SAL and ALD2732ASAL interchangeable with each other?

A: Both parts share identical electrical performance specifications and package type. The primary difference is input offset voltage: ALD2732SAL specifies 2 mV while ALD2732ASAL specifies 600 µV. Selection between these variants depends on application offset voltage tolerance requirements.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (0.154", 3.90mm width) package defines the physical footprint and pin configuration. All listed substitutes maintain this identical package specification, ensuring mechanical compatibility with existing printed circuit board layouts and assembly processes.

Q: Are there supply voltage compatibility concerns when substituting with ALD2732 parts?

A: Yes. The ALD2732 series operates within 4 V to 10 V supply range, while the OP262GS operates within 2.7 V to 12 V. Applications requiring supply voltages below 4 V or above 10 V cannot use ALD2732 substitutes.

Q: What compliance certifications apply to substitute parts?

A: The OP262GSZ, ALD2732SAL, and ALD2732ASAL are all ROHS3 compliant and REACH unaffected. These certifications ensure regulatory alignment for applications subject to environmental and hazardous substance restrictions.

Q: How does the operating temperature range affect part selection?

A: The OP262GS and OP262GSZ support -40°C to 125°C operation, suitable for industrial and extended temperature applications. The ALD2732 series is limited to 0°C to 70°C, restricting use to commercial temperature range applications. Temperature range selection depends on end-application environmental requirements.
