Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSV6191ILT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: SC-74A, SOT-753 or compatible SOT-23-5 variants
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Functional Compatibility Parameters:

• Supply voltage range must encompass or exceed the TSV6191ILT minimum of 1.5 V and maximum of 5.5 V
• Slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current must be evaluated against application-specific requirements
• Operating temperature range must support the application environment

All substitute parts listed below meet the mandatory matching criteria and are available in active product status with current manufacturing support, ensuring long-term availability and design continuity.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are in active product status with current manufacturing support, ensuring availability for new designs and production continuity. The following recommendations are based on compliance certifications and product lifecycle status:

For Automotive Applications: The LMV321Q1M5/NOPB is qualified to AEC-Q100 automotive standards and carries automotive-grade designation, making it suitable for automotive-grade system requirements where the TSV6191ILT cannot be used due to obsolescence.

For General Industrial and Consumer Applications: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the TSV6191ILT environmental specifications. All substitute parts are manufactured by established semiconductor suppliers with active product lines, ensuring long-term design support and procurement stability.

Supply Voltage Compatibility: Applications operating at the TSV6191ILT minimum supply voltage of 1.5 V require verification against substitute part minimum specifications. The LMV931SN3T1G supports 1.8 V minimum, while all other substitutes support either 1.8 V or 2.5 V minimum. Applications requiring operation below 1.8 V are limited to substitutes with lower minimum voltage specifications.

Operating Temperature Range: The MCP6001UT-I/OT maintains the TSV6191ILT operating temperature range of -40°C to 85°C. All other substitutes extend the upper temperature limit to 125°C, providing enhanced thermal margin for high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the TSV6191ILT be directly replaced with any of the listed substitute parts?

A: Direct replacement is possible only when the substitute part meets the application's specific electrical requirements. All listed substitutes share identical package types (SOT-23-5), mounting methods (surface mount), and output configurations (rail-to-rail). However, differences in slew rate, gain bandwidth product, supply current, and output current must be evaluated against circuit design specifications. Verify that the substitute part's electrical characteristics do not degrade system performance.

Q: What is the primary reason for substituting the TSV6191ILT?

A: The TSV6191ILT is classified as obsolete, meaning STMicroelectronics has discontinued manufacturing and will not support future production orders. Substitution is necessary to maintain design continuity, support ongoing production, and ensure long-term component availability for system maintenance and field repairs.

Q: Are all substitute parts available in the same package?

A: All substitute parts are available in SOT-23-5 surface mount packages with SC-74A or SOT-753 case designations, ensuring mechanical and electrical compatibility with existing PCB layouts. The LMV931SN3T1G is also available in a thin SOT-23-5 variant (TSOT-23-5), which maintains the same pin configuration and electrical interface.

Q: Which substitute part has the lowest power consumption?

A: The MCP6231UT-E/OT has the lowest supply current at 20 µA, compared to the TSV6191ILT at 10.5 µA. For applications where the TSV6191ILT's ultra-low supply current is critical, the MCP6231UT-E/OT provides the closest match among active substitutes, though it operates at a lower gain bandwidth product of 300 kHz.

Q: Which substitute parts support the full TSV6191ILT operating temperature range?

A: The MCP6001UT-I/OT is the only substitute that maintains the TSV6191ILT operating temperature range of -40°C to 85°C. All other substitutes extend the upper temperature limit to 125°C. For applications requiring operation only within -40°C to 85°C, the MCP6001UT-I/OT provides direct thermal compatibility.

Q: Can substitute parts operate at the TSV6191ILT minimum supply voltage of 1.5 V?

A: No. The TSV6191ILT operates at a minimum supply voltage of 1.5 V. All substitute parts require a minimum supply voltage of 1.8 V or higher. Applications operating at 1.5 V supply voltage cannot use any of the listed substitutes and require alternative component selection or circuit redesign.

Q: What is the difference between MCP6001UT-E/OT and MCP6001UT-I/OT?

A: Both parts are identical in electrical specifications and package type. The primary difference is the operating temperature range: MCP6001UT-E/OT operates from -40°C to 125°C, while MCP6001UT-I/OT operates from -40°C to 85°C, matching the TSV6191ILT temperature range. Select based on application temperature requirements.

Q: Which substitute part has the highest output current capability?

A: The LMV931SN3T1G provides the highest output current at 100 mA, compared to the TSV6191ILT at 63 mA. This makes the LMV931SN3T1G suitable for applications requiring higher output drive capability. Most other Microchip substitutes provide 23 mA output current, which is lower than the original part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the TSV6191ILT. All parts are suitable for applications requiring RoHS compliance and standard PCB assembly processes.
