Substitute Part Grouping Explanation

Substitution of the TLV2731CDBVT is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: SC-74A, SOT-753 (SOT-23-5)
• Mounting Type: Surface Mount
• Voltage - Supply Span: Minimum 2.7 V, Maximum 10 V
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• Current - Input Bias: 1 pA
• Current - Output / Channel: 50 mA or greater
• Slew Rate: 1.6 V/µs or greater
• Gain Bandwidth Product: 2 MHz or greater

The TLV2731CDBVT has two identified substitute parts: TLV2731IDBVR (Texas Instruments) and TS941ILT (STMicroelectronics). Both parts meet the primary substitution criteria and maintain compatibility with the original design specifications.

Parameter Comparison

Engineering Selection Recommendations

TLV2731IDBVR (Texas Instruments)

The TLV2731IDBVR is the manufacturer-recommended substitute for the TLV2731CDBVT. Both parts share identical electrical specifications, including slew rate (1.6 V/µs), gain bandwidth product (2 MHz), supply current (850 µA), and output current capability (50 mA). The TLV2731IDBVR maintains the same package configuration (SOT-23-5) and is ROHS3 compliant with MSL 1 rating.

The primary difference is product status: TLV2731IDBVR is Active, whereas TLV2731CDBVT is Last Time Buy. The TLV2731IDBVR also features an extended operating temperature range (-40°C to 85°C) compared to the original part (0°C to 70°C), providing greater flexibility for temperature-sensitive applications.

TS941ILT (STMicroelectronics)

The TS941ILT is an alternative substitute manufactured by STMicroelectronics. This part maintains package compatibility (SOT-23-5) and meets the primary substitution criteria for general-purpose, single-channel, rail-to-rail amplification. The TS941ILT is ROHS3 compliant with MSL 1 rating and operates across the -40°C to 85°C temperature range.

The TS941ILT exhibits significantly lower slew rate (0.0045 V/µs versus 1.6 V/µs) and lower gain bandwidth product (10 kHz versus 2 MHz). Additionally, output current capability is reduced to 5 mA compared to 50 mA. These differences indicate the TS941ILT is optimized for low-power, low-frequency applications and is not suitable for designs requiring the dynamic performance characteristics of the TLV2731CDBVT.

TS941AILT (STMicroelectronics)

The TS941AILT is a variant of the TS941ILT with improved voltage offset specification (5 mV versus 10 mV). Like the TS941ILT, this part is not recommended as a direct substitute for the TLV2731CDBVT due to significantly reduced slew rate, gain bandwidth product, and output current capability.

Selection Guidance:

For direct replacement of the TLV2731CDBVT with equivalent performance, select TLV2731IDBVR. This part provides identical electrical performance and is the active product from the same manufacturer. The TS941ILT and TS941AILT are suitable only for applications where reduced bandwidth and output current are acceptable trade-offs for lower power consumption.

Frequently Asked Questions (FAQ)

Q: Can the TLV2731IDBVR be used as a direct replacement for the TLV2731CDBVT?

A: Yes. The TLV2731IDBVR is electrically equivalent to the TLV2731CDBVT. Both parts share identical specifications for slew rate, gain bandwidth product, supply current, and output current. The TLV2731IDBVR is the active product variant and is recommended for new designs and existing applications requiring component replacement.

Q: What is the difference between TLV2731CDBVT and TLV2731IDBVR?

A: The primary difference is product status. The TLV2731CDBVT is Last Time Buy, while TLV2731IDBVR is Active. The TLV2731IDBVR also features an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). Electrical performance is identical.

Q: Are the TS941ILT and TS941AILT suitable replacements for the TLV2731CDBVT?

A: The TS941ILT and TS941AILT share the same package (SOT-23-5) and general-purpose amplifier classification. However, they are not direct performance equivalents. These parts have significantly lower slew rate (0.0045 V/µs versus 1.6 V/µs), lower gain bandwidth product (10 kHz versus 2 MHz), and reduced output current capability (5 mA versus 50 mA). They are suitable only for low-power, low-frequency applications.

Q: Do all substitute parts use the same package?

A: Yes. The TLV2731CDBVT, TLV2731IDBVR, TS941ILT, and TS941AILT all use the SC-74A / SOT-753 package (SOT-23-5). All parts are surface mount devices with identical pinout compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TLV2731CDBVT, TLV2731IDBVR, TS941ILT, and TS941AILT are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are suitable for applications requiring environmental compliance.

Q: What is the operating temperature range difference between the main part and substitutes?

A: The TLV2731CDBVT operates from 0°C to 70°C. The TLV2731IDBVR, TS941ILT, and TS941AILT all operate from -40°C to 85°C, providing extended temperature coverage for demanding applications.

Q: Which substitute part should I select for a new design?

A: For equivalent performance to the TLV2731CDBVT, select the TLV2731IDBVR. This part is the active product from Texas Instruments and provides identical electrical specifications. The TS941 series parts are suitable only if your application can tolerate significantly reduced bandwidth and output current.
