Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2761IDBVT is determined by strict alignment of the following electrical and mechanical 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
• Supply Voltage Range: Minimum 1.8 V, Maximum ≥ 3.6 V
• Operating Temperature Range: Minimum ≤ -40°C, Maximum ≥ 85°C

Secondary Electrical Parameters (Performance Indicators):

• Gain Bandwidth Product: 500 kHz or higher
• Slew Rate: 0.23 V/µs or higher
• Current - Supply: 20 µA or lower (for low-power applications)
• Current - Input Bias: 3 pA or lower (for high-impedance applications)

Substitute parts must satisfy all primary criteria. Secondary parameters indicate performance equivalence; deviations are acceptable when the substitute meets or exceeds the original specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

The TLV2761IDBVR is the direct equivalent of the TLV2761IDBVT. Both devices are manufactured by Texas Instruments with identical electrical specifications and packaging. The TLV2761IDBVR maintains Active product status, ensuring continued availability and supply chain support. This part is the preferred substitute for applications requiring exact performance matching and manufacturer continuity.

Alternative Substitutes (Conditional Selection):

The MCP6241UT-E/OT and MCP6241RT-E/OT (Microchip Technology) satisfy all primary substitution criteria with enhanced performance characteristics. These devices feature higher slew rate (0.3 V/µs versus 0.23 V/µs), increased gain bandwidth product (550 kHz versus 500 kHz), and superior output current capability (23 mA versus 10.2 mA). Both maintain the required supply voltage range and operating temperature specifications. The MCP6241UT-E/OT is available in Cut Tape & Digi-Reel® packaging, while the MCP6241RT-E/OT is supplied in Tape & Reel format.

The MAX4091AUK+T and MAX4091AUK+T10 (Analog Devices Inc./Maxim Integrated) are functionally compatible substitutes. These devices operate across an extended supply voltage range (2.7 V to 6 V) and extended operating temperature range (-40°C to 125°C). However, the minimum supply voltage of 2.7 V exceeds the TLV2761IDBVT specification of 1.8 V, restricting use in ultra-low-voltage applications. Supply current is elevated at 130 µA compared to 20 µA.

The TS1851ILT (STMicroelectronics) meets all primary substitution criteria with extended operating temperature range (-40°C to 125°C) and enhanced output current (48 mA). Supply current is elevated at 162 µA. This device is suitable for applications where higher output drive capability is beneficial.

Compliance and Certification:

All substitute parts listed maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory alignment with the original TLV2761IDBVT.

Frequently Asked Questions (FAQ)

Q: Can the TLV2761IDBVR be used as a direct replacement for the TLV2761IDBVT?

A: Yes. The TLV2761IDBVR is manufactured by Texas Instruments with identical electrical specifications, package type (SOT-23-5), and performance characteristics. The only difference is product status: TLV2761IDBVR is Active, while TLV2761IDBVT is Last Time Buy. No circuit modifications are required.

Q: What is the key difference between the MCP6241 series and the TLV2761IDBVT?

A: The MCP6241UT-E/OT and MCP6241RT-E/OT offer improved performance with higher slew rate (0.3 V/µs), higher gain bandwidth product (550 kHz), and greater output current (23 mA). Both maintain the 1.8 V minimum supply voltage and SOT-23-5 package. Supply current is higher at 50 µA. These devices are suitable for applications requiring enhanced dynamic performance.

Q: Can the MAX4091AUK+T be used in applications requiring 1.8 V supply voltage?

A: No. The MAX4091AUK+T has a minimum supply voltage specification of 2.7 V, which exceeds the 1.8 V lower limit of the TLV2761IDBVT. This device is not suitable for ultra-low-voltage applications operating below 2.7 V.

Q: Are all substitute parts available in SOT-23-5 packaging?

A: Yes. All substitute parts listed (TLV2761IDBVR, MAX4091AUK+T, MAX4091AUK+T10, MCP6241RT-E/OT, MCP6241UT-E/OT, and TS1851ILT) are supplied in SOT-23-5 package format with SC-74A, SOT-753 case designation. Pin-to-pin compatibility is maintained across all devices.

Q: What is the difference between MCP6241UT-E/OT and MCP6241RT-E/OT?

A: Both devices have identical electrical specifications. The difference is packaging format: MCP6241UT-E/OT is supplied in Cut Tape & Digi-Reel® format, while MCP6241RT-E/OT is supplied in Tape & Reel format. Selection depends on procurement and assembly requirements.

Q: Does the TS1851ILT operate at the same temperature range as the TLV2761IDBVT?

A: The TS1851ILT operates across -40°C to 125°C, which exceeds the TLV2761IDBVT range of -40°C to 85°C. The TS1851ILT is suitable for applications requiring extended high-temperature operation beyond 85°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory status of the TLV2761IDBVT.
