Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV4082DBVR is determined by the following critical parameters:

Functional Equivalence Criteria:

• Dual-channel configuration (2 elements)
• Open-drain output topology
• General-purpose comparator classification
• Supply voltage range compatibility with 1.5V ~ 5.5V operation

Electrical Compatibility Requirements:

• Operating temperature range must encompass or exceed -40°C ~ 85°C
• Quiescent current specifications must not exceed application power budgets
• Output current capability must support load requirements
• Propagation delay must meet timing constraints

Physical Compatibility:

• Surface-mount technology
• Package footprint compatibility with PCB design

The identified substitute parts meet these criteria through equivalent electrical performance within the specified operating envelope, though package configurations and certain performance characteristics may differ. Substitutes are grouped by package type and manufacturer to facilitate selection based on design constraints.

Engineering Selection Recommendations

TLV4082DBVR (Original Part)

The TLV4082DBVR remains the optimal selection for applications requiring the lowest supply voltage threshold at 1.5V and the smallest package footprint (SOT-23-6). This part is actively produced and maintains full ROHS3 compliance with unlimited moisture sensitivity rating.

LMV393DR2G (onsemi)

The LMV393DR2G operates within a narrower supply voltage range (2.7V ~ 5V) compared to the main part. This substitute is suitable for applications where the minimum supply voltage requirement is 2.7V or higher. The 8-SOIC package requires larger PCB footprint allocation. Quiescent current is significantly higher at 250µA, which may impact low-power applications. This part is actively produced and ROHS3 compliant.

TC75W59FU,LF (Toshiba Semiconductor)

The TC75W59FU,LF supports the widest supply voltage range (1.8V ~ 7V, ±0.9V ~ 3.5V) and offers the fastest propagation delay at 200ns. Operating temperature range matches the main part (-40°C ~ 85°C). The 8-SSOP package provides a compact alternative to larger SOIC packages. Quiescent current of 220µA is higher than the main part. This part is actively produced and ROHS3 compliant.

TSX393IDT (STMicroelectronics)

The TSX393IDT extends the operating temperature range to -40°C ~ 125°C and supports higher supply voltages (2.7V ~ 16V, ±1.35V ~ 8V). The 8-SOIC package is larger than SOT-23-6. Quiescent current of 13µA is acceptable for most applications. This part is actively produced and ROHS3 compliant.

TSX393IST (STMicroelectronics)

The TSX393IST provides the lowest quiescent current at 8µA among all substitutes, making it optimal for ultra-low-power applications. Extended operating temperature range (-40°C ~ 125°C) and wide supply voltage support (2.7V ~ 16V, ±1.35V ~ 8V) are provided. The 8-MiniSO package offers a compact footprint between SOT-23-6 and standard SOIC. This part is actively produced and ROHS3 compliant.

TSX393IYDT (STMicroelectronics)

The TSX393IYDT is qualified to AEC-Q100 automotive standards and carries automotive-grade designation. Extended operating temperature range (-40°C ~ 125°C) and wide supply voltage support (2.7V ~ 16V, ±1.35V ~ 8V) are provided. The 8-SOIC package is larger than SOT-23-6. Quiescent current of 13µA is acceptable for most applications. This part is actively produced and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the LMV393DR2G replace the TLV4082DBVR in all applications?

A: The LMV393DR2G is suitable only for applications where the minimum supply voltage is 2.7V or higher. The TLV4082DBVR operates at 1.5V minimum, which is lower than the LMV393DR2G specification. Additionally, the package footprint differs (8-SOIC versus SOT-23-6), requiring PCB redesign.

Q: Which substitute offers the best low-power performance?

A: The TSX393IST provides the lowest quiescent current at 8µA, making it the optimal choice for battery-powered or ultra-low-power applications. The TSX393IDT and TSX393IYDT both specify 13µA quiescent current, which is still acceptable for most low-power designs.

Q: What is the primary advantage of the TC75W59FU,LF?

A: The TC75W59FU,LF offers the fastest propagation delay at 200ns and supports the widest supply voltage range (1.8V ~ 7V, ±0.9V ~ 3.5V). This makes it suitable for high-speed applications and designs requiring extended voltage headroom.

Q: Are all substitute parts automotive-qualified?

A: Only the TSX393IYDT carries automotive-grade designation with AEC-Q100 qualification. The remaining substitutes are industrial-grade components. Automotive applications must use the TSX393IYDT or the original TLV4082DBVR if automotive qualification is required.

Q: How do package differences affect PCB design?

A: The TLV4082DBVR uses SOT-23-6 packaging with the smallest footprint. Substitutes use larger packages: LMV393DR2G, TSX393IDT, and TSX393IYDT use 8-SOIC; TC75W59FU,LF uses 8-SSOP; TSX393IST uses 8-MiniSO. Package selection impacts PCB layout, routing complexity, and board space allocation.

Q: Can substitutes operate at 1.5V supply voltage?

A: No. The TC75W59FU,LF operates at 1.8V minimum, while LMV393DR2G, TSX393IDT, TSX393IST, and TSX393IYDT all require 2.7V minimum supply voltage. Only the TLV4082DBVR operates at 1.5V. Applications requiring 1.5V operation must use the original part.

Q: What is the temperature range difference between substitutes?

A: The TLV4082DBVR and TC75W59FU,LF operate from -40°C to 85°C. The STMicroelectronics parts (TSX393IDT, TSX393IST, TSX393IYDT) extend the upper limit to 125°C, providing wider temperature margin for industrial and automotive applications.

Q: Is RoHS compliance consistent across all parts?

A: Yes. All parts including the main TLV4082DBVR and all substitutes are ROHS3 compliant with moisture sensitivity level 1 (unlimited). All parts carry EAR99 ECCN classification and HTSUS code 8542.39.0001.
