Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV271CDBVRG4 is determined by electrical and mechanical compatibility across the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type (CMOS topology)
• Number of Circuits (single circuit configuration)
• Output Type (rail-to-rail capability)
• Supply Voltage Range (minimum 2.7 V, maximum 16 V)
• Package Type (SOT-23-5 or equivalent surface mount)
• Mounting Type (surface mount)

Secondary Compatibility Factors:

• Slew Rate (2.6 V/µs baseline)
• Gain Bandwidth Product (3 MHz baseline)
• Input Bias Current (1 pA baseline)
• Input Offset Voltage (500 µV baseline)
• Supply Current (625 µA baseline)
• Output Current per Channel (8 mA baseline)

Substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents — Parts maintaining identical or superior electrical specifications within the same package footprint (SOT-23-5).

Category 2: Functional Equivalents — Parts with compatible electrical performance across the critical parameters but potentially different package designations (SOT-25) or manufacturer sourcing, requiring mechanical verification for PCB layout compatibility.

The TLV271CDBVR carries Active product status, ensuring long-term availability and supply chain support. Both parts share the same base product number (TLV271) and are packaged in SOT-23-5. Compliance certifications are equivalent: ROHS3 Compliant, MSL 1 (Unlimited), REACH Unaffected, and ECCN EAR99. This substitute provides direct pin-for-pin and functional compatibility with no design modifications required.

MCP6H01T-E/OT (Microchip Technology)

The MCP6H01T-E/OT is a functional equivalent offering rail-to-rail output in a single-circuit configuration within the same SOT-23-5 package. This part operates across the full 3.5 V to 16 V supply range, though the minimum supply voltage is elevated to 3.5 V compared to the 2.7 V minimum of the TLV271CDBVRG4. The MCP6H01T-E/OT features lower supply current (135 µA) and extended operating temperature range (-40°C to 125°C). Electrical performance differs: slew rate is 0.8 V/µs and gain bandwidth product is 1.2 MHz, both lower than the main part. Input bias current is 10 pA and input offset voltage is 700 µV. This substitute is suitable for applications where reduced power consumption and extended temperature operation are beneficial and where the lower slew rate and bandwidth are acceptable. Compliance status is equivalent across all certifications.

TLV271CW5-7 (Diodes Incorporated)

The TLV271CW5-7 is a CMOS amplifier sharing the TLV271 base product number with compatible electrical characteristics. This part operates across the 2.7 V to 16 V supply range and maintains 1 pA input bias current and 500 µV input offset voltage. The slew rate is 2.0 V/µs and gain bandwidth product is 1.9 MHz, both slightly lower than the main part. Supply current is 550 µA, providing modest power reduction. The package designation is SOT-25 rather than SOT-23-5, requiring mechanical verification for PCB layout compatibility. Operating temperature range is 0°C to 70°C, matching the main part. This substitute is suitable for applications where the SOT-25 package footprint is acceptable and where the slightly reduced performance specifications are compatible with circuit requirements. Compliance certifications are equivalent.

TLV271IW5-7 (Diodes Incorporated)

The TLV271IW5-7 is a CMOS amplifier with the TLV271 base product number, offering extended operating temperature range (-40°C to 125°C) compared to the main part. Electrical specifications are identical to the TLV271CW5-7: slew rate 2.0 V/µs, gain bandwidth product 1.9 MHz, supply current 550 µA, input bias current 1 pA, and input offset voltage 500 µV. Supply voltage range is 2.7 V to 16 V. The package designation is SOT-25, requiring mechanical verification for PCB layout compatibility. This substitute is suitable for applications requiring extended temperature operation and where the SOT-25 package footprint is acceptable. Compliance certifications are equivalent across all standards.

Frequently Asked Questions (FAQ)

Q: Can the TLV271CDBVR directly replace the obsolete TLV271CDBVRG4 without circuit modifications?

A: Yes. The TLV271CDBVR maintains identical electrical specifications and packaging. Both parts are SOT-23-5 surface mount devices with matching pin configurations, supply voltage ranges (2.7 V to 16 V), and performance characteristics (2.6 V/µs slew rate, 3 MHz gain bandwidth product). No circuit modifications are required for direct substitution.

Q: What are the key differences between the TLV271CDBVR and MCP6H01T-E/OT?

A: The primary differences are: (1) Minimum supply voltage is 3.5 V for the MCP6H01T-E/OT versus 2.7 V for the TLV271CDBVR, restricting use in ultra-low voltage applications; (2) Slew rate is 0.8 V/µs versus 2.6 V/µs, affecting transient response speed; (3) Gain bandwidth product is 1.2 MHz versus 3 MHz, limiting frequency response; (4) Supply current is 135 µA versus 625 µA, providing significant power reduction. The MCP6H01T-E/OT is suitable for power-constrained applications where the reduced performance specifications are acceptable.

Q: Are the TLV271CW5-7 and TLV271IW5-7 pin-compatible with the TLV271CDBVRG4?

A: Both parts use SOT-25 packaging versus the SOT-23-5 of the main part. While both are 5-pin surface mount packages, the physical footprints differ. PCB layout modifications are required to accommodate the different package dimensions. Pin functionality is compatible, but mechanical verification of the PCB layout is necessary before substitution.

Q: What is the significance of the extended temperature range in the TLV271IW5-7?

A: The TLV271IW5-7 operates from -40°C to 125°C, compared to 0°C to 70°C for the TLV271CDBVRG4. This extended range is beneficial for industrial, automotive, and harsh environment applications. However, the electrical performance specifications (slew rate 2.0 V/µs, gain bandwidth product 1.9 MHz) are slightly reduced compared to the main part.

Q: Which substitute part offers the lowest power consumption?

A: The MCP6H01T-E/OT has the lowest supply current at 135 µA, compared to 625 µA for the TLV271CDBVRG4, 625 µA for the TLV271CDBVR, and 550 µA for both the TLV271CW5-7 and TLV271IW5-7. Selection of the MCP6H01T-E/OT for power-critical applications must account for its reduced slew rate (0.8 V/µs), lower gain bandwidth product (1.2 MHz), and elevated minimum supply voltage (3.5 V).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—TLV271CDBVR, MCP6H01T-E/OT, TLV271CW5-7, and TLV271IW5-7—carry ROHS3 Compliant status. All parts also have MSL 1 (Unlimited) moisture sensitivity level, REACH Unaffected status, and ECCN EAR99 classification, matching the compliance profile of the main part.

Q: What packaging options are available for substitution?

A: The TLV271CDBVR maintains the original SOT-23-5 package. The TLV271CW5-7 and TLV271IW5-7 use SOT-25 packaging. The MCP6H01T-E/OT uses SOT-23-5. Selection between SOT-23-5 and SOT-25 depends on PCB layout constraints and available footprint space. SOT-23-5 and SOT-25 are not mechanically interchangeable without PCB redesign.

Q: Can the MCP6H01T-E/OT be used in applications requiring 2.7 V supply voltage?

A: No. The MCP6H01T-E/OT has a minimum supply voltage of 3.5 V. Applications requiring operation at 2.7 V must use the TLV271CDBVR, TLV271CW5-7, or TLV271IW5-7, all of which support the 2.7 V minimum supply voltage.

Q: What is the difference between the TLV271CW5-7 and TLV271IW5-7?

A: Both parts share identical electrical specifications and SOT-25 packaging. The primary difference is operating temperature range: TLV271CW5-7 operates 0°C to 70°C, while TLV271IW5-7 operates -40°C to 125°C. Selection depends on the required temperature range for the application.
