TLV2361IDBVT Equivalent & Substitute Parts

Part Overview

The TLV2361IDBVT is a general-purpose operational amplifier manufactured by Texas Instruments, housed in a SOT-23-5 surface mount package. This device is classified as a Last Time Buy product, indicating that the original manufacturer has discontinued or will discontinue production. The TLV2361IDBVT operates across a 2V to 5V supply range and is designed for applications requiring low-power, single-channel amplification in compact form factors.

Due to the Last Time Buy status of the TLV2361IDBVT, identifying functionally equivalent substitute components is essential for design continuity and long-term product support. Substitute parts must maintain compatibility with existing PCB layouts, supply voltage requirements, and application-level performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2361IDBVT is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the SOT-23-5 surface mount package to ensure PCB layout compatibility without redesign.

Supply Voltage Range: The substitute must operate within or encompass the 2V to 5V supply range of the original device. Substitutes with extended supply ranges remain compatible with existing designs.

Amplifier Classification: Both devices must be general-purpose operational amplifiers with a single circuit configuration.

Electrical Performance Envelope: The substitute must meet or exceed the input offset voltage specification (1 mV maximum) and maintain input bias current characteristics suitable for the application class.

Compliance and Certifications: Both parts must maintain ROHS3 compliance and MSL Level 1 rating to ensure manufacturing and storage compatibility.

The TS971ILT from STMicroelectronics meets all substitution criteria while offering enhanced performance characteristics in several parameters.

Engineering Selection Recommendations

Product Status Consideration: The TLV2361IDBVT carries a Last Time Buy status, making the TS971ILT a necessary alternative for ongoing production and future designs. The TS971ILT maintains Active product status with STMicroelectronics, ensuring long-term availability and supply chain stability.

Compliance Alignment: Both devices are ROHS3 compliant and carry MSL Level 1 ratings, ensuring compatibility with standard manufacturing processes and storage requirements. Both parts are classified as EAR99 under export control regulations and are REACH unaffected.

Package and Pinout Compatibility: Both the TLV2361IDBVT and TS971ILT use identical SOT-23-5 packaging (SC-74A, SOT-753), enabling direct PCB layout compatibility without redesign.

Supply Voltage Compatibility: The TS971ILT operates across a 2.7V to 10V supply range, which encompasses the 2V to 5V operating window of the TLV2361IDBVT. Designs operating at 2V to 2.7V require verification of the TS971ILT minimum supply specification.

Performance Enhancement: The TS971ILT provides improved slew rate (4V/µs versus 3V/µs), higher gain bandwidth product (12 MHz versus 7 MHz), and increased output current capability (100 mA versus 20 mA), making it suitable for applications requiring higher performance margins.

Frequently Asked Questions (FAQ)

Q: Can the TS971ILT be used as a direct replacement for the TLV2361IDBVT in existing designs?

A: Yes, the TS971ILT is a direct pin-compatible substitute in SOT-23-5 packaging. Both devices share identical pinout and package dimensions. Designs operating at supply voltages between 2.7V and 5V require no circuit modifications. Designs operating below 2.7V require evaluation against the TS971ILT minimum supply specification of 2.7V.

Q: What are the key differences between these two operational amplifiers?

A: The TS971ILT offers superior performance in slew rate (4V/µs versus 3V/µs), gain bandwidth product (12 MHz versus 7 MHz), and output current capability (100 mA versus 20 mA). The TS971ILT also features rail-to-rail output capability and operates across an extended temperature range (-40°C to 125°C versus -40°C to 85°C). Input offset voltage specifications are identical at 1 mV maximum.

Q: Are there supply voltage compatibility concerns when substituting the TS971ILT?

A: The TS971ILT minimum supply voltage is 2.7V, compared to 2V for the TLV2361IDBVT. Designs operating at supply voltages below 2.7V are not compatible with the TS971ILT. The maximum supply voltage of the TS971ILT (10V) exceeds that of the TLV2361IDBVT (5V), providing additional design flexibility for higher-voltage applications.

Q: What is the significance of the rail-to-rail output specification on the TS971ILT?

A: Rail-to-rail output capability on the TS971ILT allows the output voltage to swing closer to the positive and negative supply rails compared to conventional operational amplifiers. This characteristic provides improved signal dynamic range in low-supply-voltage applications and is not present in the TLV2361IDBVT.

Q: How do the input bias current specifications compare?

A: The TLV2361IDBVT specifies 20 nA input bias current, while the TS971ILT specifies 200 nA. For applications with high-impedance input sources or precision transimpedance configurations, this tenfold difference may require circuit analysis to confirm acceptable performance.

Q: Are both devices suitable for the same operating temperature range?

A: The TLV2361IDBVT operates from -40°C to 85°C, while the TS971ILT operates from -40°C to 125°C. The TS971ILT provides extended high-temperature operation capability. Applications requiring operation above 85°C must use the TS971ILT.

Q: What packaging options are available for these devices?

A: Both the TLV2361IDBVT and TS971ILT are supplied in SOT-23-5 surface mount packaging. The TLV2361IDBVT is available in Tape & Reel (TR) format, while the TS971ILT is available in Cut Tape (CT) and Digi-Reel® formats. Packaging format selection depends on manufacturing and procurement requirements.
