Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2731IDBVT is determined by electrical and mechanical compatibility across the following critical parameters:

Mechanical Compatibility: All substitute parts must maintain identical package configuration (SOT-23-5 / SC-74A, SOT-753) and surface mount mounting type to ensure PCB layout compatibility without redesign.

Functional Compatibility: Substitute parts must operate as single-circuit general-purpose operational amplifiers with rail-to-rail output capability and identical single-circuit configuration.

Electrical Operating Range: Substitute parts must support the supply voltage span of 2.7 V to 10 V and operate within the temperature range of -40°C to 85°C.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and MSL rating of 1 (Unlimited) to satisfy procurement and environmental requirements.

Performance Parameters: While slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current may vary between substitute parts, these variations are acceptable provided the substitute part meets the functional requirements of the application circuit.

Engineering Selection Recommendations

Primary Substitute (Manufacturer Recommended): TLV2731IDBVR is the direct equivalent manufactured by Texas Instruments. This part maintains identical electrical specifications, package configuration, and regulatory compliance. The TLV2731IDBVR differs only in packaging format (Tape & Reel with different reel specification) and product status (Active vs. Last Time Buy). This part is recommended for applications requiring performance characteristics identical to the TLV2731IDBVT.

Alternative Substitutes: TS941AILT and TS941ILT are manufactured by STMicroelectronics and provide functional equivalence in package and mounting configuration. These parts operate within the required supply voltage range and temperature specifications. However, these alternatives exhibit reduced performance in slew rate (0.0045 V/µs vs. 1.6 V/µs), gain bandwidth product (10 kHz vs. 2 MHz), supply current (1.2 µA vs. 850 µA), output current capability (5 mA vs. 50 mA), and input offset voltage specifications. These alternatives are suitable for applications where reduced bandwidth and output current requirements are acceptable.

Compliance Status: All substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), satisfying regulatory and environmental requirements equivalent to the TLV2731IDBVT.

Frequently Asked Questions (FAQ)

Q: Can TLV2731IDBVR be used as a direct replacement for TLV2731IDBVT?

A: Yes. TLV2731IDBVR is electrically and mechanically identical to TLV2731IDBVT. Both parts share identical specifications for amplifier type, circuit count, output type, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, supply voltage range, operating temperature, package configuration, and regulatory compliance. The difference is product status (Active vs. Last Time Buy) and packaging format.

Q: Are TS941AILT and TS941ILT pin-compatible with TLV2731IDBVT?

A: Yes. Both TS941AILT and TS941ILT utilize the identical SOT-23-5 package configuration (SC-74A, SOT-753) with surface mount mounting type. Pin compatibility is maintained for PCB layout purposes.

Q: What are the performance differences between TLV2731IDBVT and TS941 series parts?

A: TS941AILT and TS941ILT exhibit significantly reduced performance specifications. Slew rate is reduced from 1.6 V/µs to 0.0045 V/µs. Gain bandwidth product is reduced from 2 MHz to 10 kHz. Supply current is reduced from 850 µA to 1.2 µA. Output current capability is reduced from 50 mA to 5 mA. Input offset voltage is increased from 700 µV to 5 mV (TS941AILT) or 10 mV (TS941ILT). These differences indicate the TS941 series is optimized for low-power applications with reduced bandwidth requirements.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. TLV2731IDBVR, TS941AILT, and TS941ILT all maintain ROHS3 compliance and MSL rating of 1 (Unlimited), matching the regulatory status of TLV2731IDBVT.

Q: What is the minimum supply voltage for each substitute part?

A: TLV2731IDBVT and TLV2731IDBVR support minimum supply voltage of 2.7 V. TS941AILT and TS941ILT support minimum supply voltage of 2.5 V, providing slightly broader low-voltage operation capability.

Q: Which substitute part should be selected for high-speed applications?

A: TLV2731IDBVR maintains the high-speed performance characteristics of the original TLV2731IDBVT, with 1.6 V/µs slew rate and 2 MHz gain bandwidth product. TS941 series parts are not suitable for high-speed applications due to significantly reduced bandwidth specifications.
