TSB7192IST Equivalent & Substitute Parts

Part Overview

The TSB7192IST is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring dual-channel configuration in an 8-MiniSO surface-mount package. This device is classified as an active linear amplifier with rail-to-rail output capability, designed for applications requiring low-power, low-offset voltage performance across automotive and industrial temperature ranges. The part maintains active product status with AEC-Q100 automotive qualification and ROHS3 compliance.

Substitute parts are identified when equivalent functional performance can be achieved within specified electrical and mechanical parameter tolerances, enabling design flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSB7192IST is determined by the following critical parameters:

Functional Equivalence Criteria:

• Dual-channel (2 circuit) configuration
• Rail-to-rail output capability
• Surface-mount package compatibility (8-pin TSSOP/MSOP footprint)
• Supply voltage range overlap (minimum 2.7 V to 36 V maximum)
• Output current capability of at least 50 mA per channel
• Gain-bandwidth product of 22 MHz or greater

Compliance & Qualification Criteria:

• ROHS3 compliance
• Active product status
• Operating temperature range supporting -40°C minimum

The identified substitute parts (OPA1652AIDGKR and OPA1662AIDGKRQ1) satisfy these core requirements while maintaining mechanical and electrical compatibility within the specified parameter envelope.

Engineering Selection Recommendations

TSB7192IST (Primary Part)

The TSB7192IST is recommended for applications requiring automotive-grade qualification with AEC-Q100 certification. This part supports the full specified operating temperature range (-40°C to 125°C) and maintains active product status with established supply availability (633 pcs in stock). The device is suitable for automotive and industrial applications where extended temperature performance and automotive compliance are mandatory.

OPA1662AIDGKRQ1 (Preferred Substitute)

The OPA1662AIDGKRQ1 is the primary substitute option, offering automotive-grade qualification with AEC-Q100 certification matching the TSB7192IST. This part maintains identical gain-bandwidth product (22 MHz), equivalent output current capability (50 mA per channel), and compatible supply voltage range (3.0 V to 36 V). The operating temperature range is limited to -40°C to 85°C, which is acceptable for most automotive applications. Supply availability is confirmed (7900 pcs in stock).

OPA1652AIDGKR (Secondary Substitute)

The OPA1652AIDGKR is a commercial-grade alternative without automotive qualification. This part does not carry AEC-Q100 certification and is classified as audio-grade rather than general-purpose. The minimum supply voltage requirement (4.5 V) is higher than the TSB7192IST (2.7 V), and output current capability is reduced to 30 mA per channel. This part is suitable only for non-automotive applications where automotive qualification is not required. Supply availability is high (38500 pcs in stock).

Frequently Asked Questions (FAQ)

Q: Can the OPA1652AIDGKR be used as a direct replacement for the TSB7192IST in automotive applications?

A: No. The OPA1652AIDGKR lacks AEC-Q100 automotive qualification and is classified as commercial-grade. Automotive applications requiring compliance with automotive standards must use either the TSB7192IST or OPA1662AIDGKRQ1.

Q: What is the primary difference between the two Texas Instruments substitutes?

A: The OPA1662AIDGKRQ1 carries AEC-Q100 automotive qualification and matches the TSB7192IST gain-bandwidth product (22 MHz). The OPA1652AIDGKR is commercial-grade without automotive qualification and has a lower gain-bandwidth product (18 MHz) and reduced output current (30 mA vs. 50 mA per channel).

Q: Are the package footprints identical across all three parts?

A: Yes. All three parts use the 8-TSSOP/8-MSOP surface-mount package with 0.118" width (3.00mm). PCB layout compatibility is maintained across substitutions.

Q: What is the impact of the OPA1662AIDGKRQ1 operating temperature limit of 85°C versus the TSB7192IST limit of 125°C?

A: The OPA1662AIDGKRQ1 supports the standard automotive operating temperature range (-40°C to 85°C). Applications requiring operation above 85°C must use the TSB7192IST.

Q: Can the OPA1652AIDGKR operate at the TSB7192IST minimum supply voltage of 2.7 V?

A: No. The OPA1652AIDGKR requires a minimum supply voltage of 4.5 V. Applications operating below 4.5 V must use either the TSB7192IST (2.7 V minimum) or OPA1662AIDGKRQ1 (3.0 V minimum).

Q: Are all three parts ROHS3 compliant?

A: Yes. The TSB7192IST, OPA1652AIDGKR, and OPA1662AIDGKRQ1 are all ROHS3 compliant with REACH unaffected status.

Q: What is the moisture sensitivity level difference between the parts?

A: The TSB7192IST and OPA1652AIDGKR have MSL 1 (unlimited shelf life). The OPA1662AIDGKRQ1 has MSL 2 (1-year shelf life), requiring controlled storage conditions.
