TSH111ID Equivalent & Substitute Parts

Part Overview

The TSH111ID is a current feedback amplifier manufactured by STMicroelectronics, housed in an 8-SOIC surface mount package. This device is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The TSH111ID delivers a slew rate of 450V/µs with a -3dB bandwidth of 100 MHz, operating across a supply voltage range of 5V to 12V with an operating temperature range of -40°C to 85°C. Due to its obsolete status, equivalent alternatives must be evaluated based on electrical performance parameters and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TSH111ID are evaluated based on the following critical parameters that determine functional equivalence:

Mechanical Compatibility: All substitute parts must utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure PCB layout compatibility without redesign.

Electrical Performance Envelope: Substitute parts must operate within the supply voltage range of 5V to 12V and maintain the operating temperature range of -40°C to 85°C. The amplifier type (current feedback) and single-circuit configuration are fundamental to the functional category.

Performance Characteristics: While the TSH111ID establishes baseline performance with 450V/µs slew rate and 100 MHz bandwidth, substitute parts may exceed these specifications. Substitute components with higher slew rates and bandwidth values remain compatible as they do not reduce circuit performance below application requirements.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory and supply chain requirements.

The following substitute parts meet these criteria and are grouped by their performance tier relative to the TSH111ID baseline.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: OPA695IDR

The OPA695IDR is the preferred substitute for the TSH111ID. This Texas Instruments component maintains active product status, ensuring long-term availability and supply chain stability. The OPA695IDR operates within the identical supply voltage range (5V to 12V) and temperature range (-40°C to 85°C) as the TSH111ID. While the OPA695IDR exhibits significantly higher performance specifications (4300V/µs slew rate and 1.7 GHz bandwidth compared to the TSH111ID's 450V/µs and 100 MHz), these enhanced characteristics do not create incompatibility. The 8-SOIC package is identical, enabling direct PCB substitution. ROHS3 compliance and REACH unaffected status align with regulatory requirements. The OPA695IDR is available in Cut Tape and Digi-Reel packaging with 8509 units in stock.

Secondary Recommendation: OPA684IDR

The OPA684IDR provides an alternative with active product status and intermediate performance characteristics. This device delivers 820V/µs slew rate and 210 MHz bandwidth, positioning it between the TSH111ID baseline and higher-performance alternatives. The OPA684IDR maintains identical supply voltage and temperature operating ranges. The 8-SOIC package ensures mechanical compatibility. ROHS3 compliance is maintained. The OPA684IDR is available in Tape & Reel packaging with 5822 units in stock.

Tertiary Recommendation: OPA684ID

The OPA684ID offers the same electrical specifications as the OPA684IDR but is supplied in Tube packaging. This option is suitable for applications where Tube packaging is preferred or required. Product status is active with 1418 units in stock.

Alternative Consideration: EL5162ISZ-T7A

The EL5162ISZ-T7A from Renesas Electronics provides the highest performance tier with 4000V/µs slew rate and 500 MHz bandwidth. However, this device carries obsolete product status, limiting its suitability for long-term production applications. The EL5162ISZ-T7A maintains supply voltage and temperature compatibility with identical 8-SOIC packaging. This option is appropriate only for legacy system support where supply chain continuity is not a primary concern.

Not Recommended: OPA693ID

The OPA693ID is classified as a buffer amplifier rather than a current feedback amplifier, representing a different functional category. While it shares the 8-SOIC package and supply voltage range, its application context differs fundamentally from the TSH111ID. This device is not suitable as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can the OPA695IDR be used as a direct replacement for the TSH111ID without PCB modifications?

A: Yes. The OPA695IDR utilizes the identical 8-SOIC (0.154", 3.90mm Width) surface mount package as the TSH111ID. Pin-to-pin compatibility and footprint alignment enable direct substitution without PCB redesign. Both devices operate within the 5V to 12V supply voltage range and -40°C to 85°C temperature range.

Q: Why do substitute parts have higher slew rates and bandwidth than the TSH111ID?

A: Substitute components represent current-generation technology with enhanced performance specifications. Higher slew rates and bandwidth values do not reduce circuit performance below application requirements; they provide additional performance margin. Applications designed for the TSH111ID's 450V/µs slew rate and 100 MHz bandwidth operate successfully with substitute parts offering 4300V/µs and 1.7 GHz respectively.

Q: What is the difference between OPA695ID and OPA695IDR?

A: Both devices share identical electrical specifications and performance characteristics. The primary difference is packaging format: OPA695ID is supplied in Tube packaging, while OPA695IDR is supplied in Cut Tape and Digi-Reel format. Selection depends on assembly process requirements and inventory management preferences.

Q: Is the OPA693ID a suitable substitute?

A: No. The OPA693ID is classified as a buffer amplifier, not a current feedback amplifier. While it shares the 8-SOIC package and supply voltage compatibility, its functional category differs from the TSH111ID. Direct substitution is not appropriate.

Q: Why is the EL5162ISZ-T7A not recommended despite superior performance?

A: The EL5162ISZ-T7A carries obsolete product status, creating supply chain risk for long-term production applications. While it provides higher performance specifications and maintains package and voltage compatibility, its obsolete classification makes it unsuitable for designs requiring sustained component availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements identical to the TSH111ID.

Q: What is the significance of product status (Active, Last Time Buy, Obsolete)?

A: Product status indicates supply chain availability and manufacturer support. Active status ensures ongoing production and long-term availability. Last Time Buy status indicates limited remaining production with a defined end date. Obsolete status means production has ceased, creating supply uncertainty. For new designs and sustained production, Active status components are preferred.

Q: Can substitute parts be mixed in the same design?

A: Yes. All substitute parts maintain electrical and mechanical compatibility with the TSH111ID. However, design consistency and inventory management typically favor standardizing on a single substitute component across production batches.
