TLV341AIDBVT Equivalent & Substitute Parts

Part Overview

The TLV341AIDBVT is a general-purpose operational amplifier manufactured by Texas Instruments, featuring rail-to-rail output capability in a compact SOT-23-6 surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The TLV341AIDBVT serves applications requiring low-power, single-channel amplification across supply voltages from 1.5 V to 5.5 V. Identification of equivalent and substitute parts is necessary due to product status transition and to ensure design continuity for new production runs or component replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV341AIDBVT is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type (General Purpose)
• Number of circuits (1)
• Output type (Rail-to-Rail)
• Operating temperature range (-40°C to 125°C)
• Supply voltage span compatibility (minimum 1.5 V to maximum 5.5 V)
• RoHS3 compliance and MSL rating

Mechanical Compatibility Criteria:

• Surface mount mounting type
• Package footprint and pin configuration

Substitute parts are grouped into two categories based on package type:

Category 1: Direct Package Match (SOT-23-6)

• TLV341AIDBVR: Identical electrical specifications, alternative packaging (Cut Tape & Digi-Reel vs. Tape & Reel)
• LMV791MKX/NOPB: SOT-23-THIN package variant with enhanced performance characteristics

Category 2: Alternative Package (SC-70-6)

• LMV341MG/NOPB: SC-70-6 package with modified electrical parameters
• LMV341MGX/NOPB: SC-70-6 package variant with modified electrical parameters

Parameter Comparison

Engineering Selection Recommendations

TLV341AIDBVR is the primary substitute for TLV341AIDBVT. Both devices share identical electrical specifications and SOT-23-6 package configuration. The distinction lies in packaging format: TLV341AIDBVR is supplied in Cut Tape & Digi-Reel format with significantly higher inventory availability (999,400 pcs vs. 2,444 pcs). Both maintain Active product status, ensuring long-term supply continuity. This substitution requires no circuit redesign and presents no electrical or mechanical compatibility concerns.

LMV341MG/NOPB and LMV341MGX/NOPB are substitutes requiring package redesign. These devices employ SC-70-6 package configuration instead of SOT-23-6, necessitating PCB layout modification. Electrical differences include reduced minimum supply voltage (2.7 V vs. 1.5 V), lower gain bandwidth product (1 MHz vs. 2.3 MHz), and improved input offset voltage (250 µV vs. 300 µV). These substitutes are suitable only when PCB redesign is feasible and the reduced minimum supply voltage does not conflict with application requirements.

LMV791MKX/NOPB is a performance-enhanced substitute available in SOT-23-THIN package. This device offers significantly higher slew rate (11.5 V/µs vs. 1 V/µs), gain bandwidth product (17 MHz vs. 2.3 MHz), and improved input offset voltage (100 µV vs. 300 µV). Supply current consumption increases substantially (1.15 mA vs. 75 µA). This substitute is applicable only when higher bandwidth and slew rate performance are required and increased power consumption is acceptable. Minimum supply voltage is 1.8 V, compatible with the original 1.5 V specification for most applications.

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and operating temperature range of -40°C to 125°C, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q1: Can TLV341AIDBVR be used as a direct replacement for TLV341AIDBVT without circuit modification?

A: Yes. TLV341AIDBVR is electrically and mechanically identical to TLV341AIDBVT. Both devices feature identical slew rate (1 V/µs), gain bandwidth product (2.3 MHz), input bias current (1 pA), input offset voltage (300 µV), supply current (75 µA), output current (115 mA), and supply voltage range (1.5 V to 5.5 V). The only difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel). No PCB layout changes or circuit redesign are required.

Q2: What are the key differences between SOT-23-6 and SC-70-6 packages?

A: SOT-23-6 and SC-70-6 are distinct surface mount packages with different physical dimensions and pin configurations. SOT-23-6 is larger than SC-70-6. Substitution between these packages requires PCB layout redesign, including trace routing, pad dimensions, and component placement modifications. Mechanical compatibility cannot be achieved without physical board changes.

Q3: Why does LMV791MKX/NOPB have higher supply current consumption than TLV341AIDBVT?

A: LMV791MKX/NOPB is designed for higher-bandwidth applications, with gain bandwidth product of 17 MHz compared to 2.3 MHz in TLV341AIDBVT. Enhanced performance characteristics, including slew rate of 11.5 V/µs versus 1 V/µs, require higher quiescent current consumption (1.15 mA vs. 75 µA). This trade-off between power consumption and bandwidth performance is inherent to the device architecture.

Q4: Can LMV341MG/NOPB be used in applications requiring 1.5 V minimum supply voltage?

A: No. LMV341MG/NOPB specifies minimum supply voltage of 2.7 V, whereas TLV341AIDBVT operates at 1.5 V minimum. Applications requiring operation below 2.7 V supply voltage cannot use LMV341MG/NOPB. Verify application supply voltage requirements before selecting this substitute.

Q5: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—TLV341AIDBVR, LMV341MG/NOPB, LMV341MGX/NOPB, and LMV791MKX/NOPB—are ROHS3 compliant with MSL rating of 1 (Unlimited). Regulatory and environmental compliance is maintained across all substitutes.

Q6: What is the difference between LMV341MG/NOPB and LMV341MGX/NOPB?

A: Both devices share identical electrical specifications and SC-70-6 package configuration. The distinction is packaging format: LMV341MG/NOPB is supplied in Tape & Reel format with 35,300 pcs inventory, while LMV341MGX/NOPB is also in Tape & Reel format with 2,350 pcs inventory. Electrical performance and mechanical compatibility are equivalent.

Q7: Which substitute is recommended for new production designs?

A: TLV341AIDBVR is recommended for new production designs requiring direct replacement of TLV341AIDBVT. This device maintains Active product status, ensuring long-term availability and supply continuity. Inventory availability is substantially higher (999,400 pcs), supporting volume production requirements. No circuit or PCB redesign is necessary.
