Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSH10ID is determined by strict alignment of electrical and mechanical parameters within the operational amplifier category. The following criteria establish valid substitution:

Primary Substitution Criteria:

• Package compatibility: 8-SOIC surface mount form factor
• Single-circuit configuration: 1 operational amplifier per package
• Operating temperature range: Minimum -40°C to maximum 125°C (or extended range)
• Supply voltage span: Minimum 6 V to maximum 12 V
• Output current capability: Minimum 70 mA per channel
• RoHS3 compliance and MSL 1 rating

Secondary Electrical Considerations:

• Slew rate and bandwidth performance characteristics
• Input bias current and input offset voltage specifications
• Supply current consumption
• Amplifier topology (general purpose or voltage feedback)

The substitute parts AD8055ARZ and AD9631ARZ-REEL meet the primary mechanical and compliance requirements while offering enhanced electrical performance characteristics.

Engineering Selection Recommendations

AD9631ARZ-REEL Selection Criteria:

The AD9631ARZ-REEL is the primary substitute for the TSH10ID. This part maintains full mechanical compatibility with identical 8-SOIC package dimensions and surface mount configuration. The AD9631ARZ-REEL operates across the required supply voltage range of 6 V to 12 V and delivers the specified 70 mA output current per channel. Both devices are ROHS3 compliant with MSL 1 rating. The AD9631ARZ-REEL is currently in active production status, ensuring long-term availability and supply chain continuity. The operating temperature range extends to -40°C minimum; however, the maximum operating temperature is 85°C, which is 40°C lower than the TSH10ID specification. This temperature limitation must be evaluated against application requirements.

AD8055ARZ Selection Criteria:

The AD8055ARZ serves as an alternative substitute with identical package and compliance specifications. This device operates across 8 V to 12 V supply range, which does not fully cover the TSH10ID minimum of 6 V. The AD8055ARZ delivers 60 mA output current per channel, which is 10 mA below the TSH10ID specification of 70 mA. The AD8055ARZ is currently in active production status. The operating temperature range matches the TSH10ID at -40°C to 125°C.

Compliance and Regulatory Status:

Both substitute parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes and environmental regulations. Both parts carry EAR99 ECCN classification and REACH unaffected status, matching the regulatory profile of the original TSH10ID.

Frequently Asked Questions (FAQ)

Q: Can the AD9631ARZ-REEL directly replace the TSH10ID in all applications?

A: The AD9631ARZ-REEL provides mechanical and electrical compatibility for most applications. The maximum operating temperature of 85°C must be verified against application requirements, as the TSH10ID operates to 125°C. All other critical parameters including package, supply voltage range, output current, and compliance certifications are compatible.

Q: What is the difference between the AD8055ARZ and AD9631ARZ-REEL?

A: Both parts are voltage feedback amplifiers in 8-SOIC packages. The AD8055ARZ requires a minimum supply voltage of 8 V (versus 6 V for both the TSH10ID and AD9631ARZ-REEL) and delivers 60 mA output current (versus 70 mA for the TSH10ID and AD9631ARZ-REEL). The AD8055ARZ operates to 125°C maximum temperature, matching the TSH10ID. The AD9631ARZ-REEL operates to 85°C maximum temperature.

Q: Are there packaging format differences between the substitute parts?

A: Yes. The AD8055ARZ is supplied in Tube packaging, while the AD9631ARZ-REEL is supplied in Tape & Reel format. Both packaging formats are compatible with standard surface mount assembly processes. Selection between formats depends on production volume and assembly equipment configuration.

Q: What are the key electrical performance differences?

A: The substitute parts offer significantly higher slew rates (1300–1400 V/µs versus 150 V/µs) and bandwidth (300–320 MHz versus 140 MHz). The AD8055ARZ exhibits lower input bias current (0.4 µA versus 5 µA). These performance enhancements are beneficial for high-speed applications but do not prevent substitution in applications designed for the TSH10ID specifications.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both AD8055ARZ and AD9631ARZ-REEL are ROHS3 compliant with MSL 1 rating and REACH unaffected status, matching the regulatory compliance of the TSH10ID.

Q: What supply voltage range must be verified for substitution?

A: The TSH10ID operates from 6 V to 12 V. The AD9631ARZ-REEL maintains this full range. The AD8055ARZ operates from 8 V to 12 V, which does not cover the 6 V to 8 V range of the original part. Applications requiring operation below 8 V must use the AD9631ARZ-REEL.

Q: Can both substitute parts deliver the required 70 mA output current?

A: The AD9631ARZ-REEL delivers 70 mA per channel, matching the TSH10ID specification. The AD8055ARZ delivers 60 mA per channel, which is 10 mA below the requirement. Applications requiring full 70 mA output current must use the AD9631ARZ-REEL.
