TLE2074AIN Equivalent & Substitute Parts

Part Overview

The TLE2074AIN is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a 4-circuit integrated circuit in a 14-DIP package. This device is designed for applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier architectures. The TLE2074AIN maintains Active product status with full RoHS3 compliance and REACH unaffected designation.

Substitute parts become necessary when primary inventory is unavailable, when supply chain constraints occur, or when design flexibility permits alternative amplifier topologies that meet application requirements. Equivalent parts must maintain compatible package geometry, pin configuration, and electrical performance within acceptable operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE2074AIN is determined by the following critical parameters:

Package Compatibility: All substitute parts must use 14-DIP (0.300", 7.62mm) through-hole mounting to ensure direct PCB compatibility without layout modifications.

Amplifier Architecture: The TLE2074AIN employs J-FET input topology. The LT1058CN#PBF maintains identical J-FET architecture with 4 circuits, ensuring functional equivalence. The LT1356CN#PBF uses voltage feedback topology with 2 circuits, representing a different amplifier class suitable only for applications where circuit count and topology flexibility permit redesign.

Electrical Performance Envelope: Substitute parts must operate within the supply voltage range of the main part (4.5V to 38V minimum). Input bias current and input offset voltage characteristics must be compatible with application requirements.

Compliance & Status: All substitute parts maintain Active product status, RoHS3 compliance, and REACH unaffected designation, ensuring regulatory alignment with the TLE2074AIN.

Parameter Comparison

Engineering Selection Recommendations

LT1058CN#PBF Selection Criteria:

The LT1058CN#PBF is the primary direct substitute for the TLE2074AIN. Both devices employ J-FET input architecture with 4-circuit configuration in identical 14-DIP packaging. This substitute maintains functional equivalence for applications prioritizing low input bias current characteristics. The LT1058CN#PBF operates within a reduced supply voltage range (20V to 36V minimum), which is compatible with the TLE2074AIN's 4.5V to 38V envelope for applications operating above 20V. The LT1058CN#PBF exhibits lower slew rate (13V/µs versus 45V/µs) and reduced gain bandwidth product (5MHz versus 10MHz), requiring evaluation for high-speed or high-frequency applications. Operating temperature range is narrower (0°C to 70°C versus -40°C to 85°C), limiting use in extended temperature environments. All regulatory compliance designations align with the main part.

LT1356CN#PBF Selection Criteria:

The LT1356CN#PBF represents an alternative topology using voltage feedback amplifier architecture with 2 circuits in 14-DIP packaging. This substitute is applicable only when circuit count reduction is acceptable and when voltage feedback topology meets application requirements. The LT1356CN#PBF provides superior slew rate (400V/µs) and higher gain bandwidth product (12MHz), suitable for high-speed signal processing. Supply voltage range (5V to 30V) is narrower than the TLE2074AIN, restricting use in high-voltage applications. Input bias current is significantly higher (80nA versus 1pA), unsuitable for applications requiring ultra-low bias current. Operating temperature range (0°C to 70°C) is restricted compared to the main part. Selection of this substitute requires circuit redesign to accommodate 2-circuit configuration and voltage feedback topology.

Frequently Asked Questions (FAQ)

Q: Can the LT1058CN#PBF directly replace the TLE2074AIN without PCB modifications?

A: The LT1058CN#PBF uses identical 14-DIP package geometry and pin configuration, permitting direct socket substitution. However, electrical performance differences (slew rate, gain bandwidth product, operating temperature range) require application-level evaluation before implementation.

Q: What is the primary difference between the TLE2074AIN and LT1356CN#PBF?

A: The TLE2074AIN is a 4-circuit J-FET amplifier; the LT1356CN#PBF is a 2-circuit voltage feedback amplifier. These represent different amplifier topologies and circuit counts. The LT1356CN#PBF is suitable only for applications where topology change and reduced circuit count are acceptable.

Q: Does the LT1058CN#PBF operate at the TLE2074AIN's minimum supply voltage of 4.5V?

A: No. The LT1058CN#PBF requires a minimum supply voltage of 20V. Applications operating below 20V must use the TLE2074AIN or evaluate alternative parts with lower minimum supply voltage specifications.

Q: Are all three parts RoHS3 compliant?

A: Yes. The TLE2074AIN, LT1058CN#PBF, and LT1356CN#PBF all maintain ROHS3 compliance and REACH unaffected designation.

Q: Which substitute part is suitable for applications requiring operation below 0°C?

A: Only the TLE2074AIN operates at -40°C. Both substitute parts (LT1058CN#PBF and LT1356CN#PBF) have minimum operating temperatures of 0°C, making them unsuitable for extended low-temperature applications.

Q: What is the input bias current difference between the main part and substitutes?

A: The TLE2074AIN has 1pA input bias current. The LT1058CN#PBF has 7pA, and the LT1356CN#PBF has 80nA. Applications requiring ultra-low input bias current must use the TLE2074AIN or LT1058CN#PBF.
