TL074CPWRE4 Equivalent & Substitute Parts

Part Overview

The TL074CPWRE4 is a J-FET input operational amplifier featuring four independent circuits in a 14-TSSOP surface mount package. This device is designed for applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier topologies. The TL074CPWRE4 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL074CPWRE4 is determined by the following critical parameters: amplifier type (J-FET), number of circuits (4), package type (14-TSSOP), mounting configuration (surface mount), and electrical operating ranges (supply voltage 10–30 V, operating temperature 0–70°C). Substitute parts must maintain identical or superior electrical performance within these constraints while preserving mechanical compatibility.

Substitutes are grouped into two categories:

Category 1: Direct J-FET Equivalents (Texas Instruments & STMicroelectronics) Parts maintaining J-FET amplifier topology with identical or enhanced electrical specifications. These include TL074CPWR (Texas Instruments), TL084CPT, and TL084IPT (STMicroelectronics).

Category 2: General Purpose Alternative (Analog Devices Inc.) The ADA4077-4ARUZ and ADA4077-4ARUZ-RL represent general purpose amplifier alternatives with different amplifier topology but compatible package and pin configuration. These parts operate across an extended temperature range and lower supply voltage minimum.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TL074CPWR

The TL074CPWR is the direct active equivalent of the discontinued TL074CPWRE4. Both parts are manufactured by Texas Instruments and share identical electrical specifications including J-FET amplifier topology, slew rate (13 V/µs), gain bandwidth product (5.25 MHz), input bias current (65 pA), and supply voltage range (10–30 V). The TL074CPWR is currently in active production with substantial inventory availability (31,027 units). This part requires no circuit redesign and provides pin-for-pin compatibility.

Secondary Recommendation: TL084IPT

The TL084IPT, manufactured by STMicroelectronics, maintains J-FET amplifier topology with enhanced electrical performance. It features superior input bias current (20 pA versus 65 pA), higher slew rate (16 V/µs versus 13 V/µs), and extended operating temperature range (-40°C to 105°C versus 0°C to 70°C). The TL084IPT supports a wider supply voltage range (6–36 V) and carries AEC-Q100 automotive qualification. This part is suitable for applications requiring improved performance margins or extended temperature operation.

Tertiary Recommendation: TL084CPT

The TL084CPT offers identical performance characteristics to the TL084IPT with automotive grade qualification and AEC-Q100 compliance. Operating temperature range is limited to 0–70°C, matching the original TL074CPWRE4 specification. This part is appropriate for applications requiring automotive-grade components within the standard temperature range.

Alternative Consideration: ADA4077-4ARUZ / ADA4077-4ARUZ-RL

The Analog Devices ADA4077 series represents a general purpose amplifier alternative with different topology. These parts feature significantly lower input offset voltage (15 µV versus 3 mV), reduced supply current (400 µA versus 1.4 mA), and extended operating temperature range (-40°C to 125°C). However, input bias current is substantially higher (400 pA versus 65 pA), and slew rate is lower (1.2 V/µs versus 13 V/µs). Selection of ADA4077 parts requires circuit analysis to confirm compatibility with application requirements, particularly for high-impedance input circuits where input bias current is critical.

Frequently Asked Questions (FAQ)

Q: Can the TL074CPWR be used as a direct replacement for the TL074CPWRE4?

A: Yes. The TL074CPWR is electrically and mechanically identical to the TL074CPWRE4. Both parts share the same manufacturer (Texas Instruments), amplifier type (J-FET), electrical specifications, and 14-TSSOP package configuration. No circuit modifications are required.

Q: What is the difference between TL084CPT and TL084IPT?

A: Both parts are manufactured by STMicroelectronics and share identical electrical specifications. The primary difference is operating temperature range: TL084CPT operates from 0°C to 70°C, while TL084IPT operates from -40°C to 105°C. Both carry AEC-Q100 automotive qualification. Selection depends on the required operating temperature range for the application.

Q: Why do the ADA4077 parts have different electrical characteristics?

A: The ADA4077 series uses general purpose amplifier topology rather than J-FET topology. This results in different electrical characteristics: lower input offset voltage, reduced supply current, but higher input bias current and lower slew rate. These parts are compatible at the package and pinout level but may not be suitable for all applications, particularly those sensitive to input bias current or requiring high slew rate performance.

Q: Are all substitute parts available in the same packaging options?

A: All substitute parts are available in 14-TSSOP surface mount package. Packaging options (Cut Tape, Digi-Reel, Tube, Tape & Reel) vary by manufacturer and part number. Verify packaging availability with your supplier based on procurement requirements.

Q: What is the significance of RoHS3 compliance and REACH status?

A: All listed parts, including the original TL074CPWRE4 and all substitutes, are ROHS3 compliant and REACH unaffected. This ensures regulatory compliance for applications subject to European Union environmental directives and allows unrestricted use in regulated markets.

Q: Can I use the ADA4077-4ARUZ in a circuit designed for the TL074CPWRE4?

A: Mechanical and pinout compatibility exists, but electrical compatibility requires circuit analysis. The ADA4077 has significantly different input bias current (400 pA versus 65 pA) and slew rate (1.2 V/µs versus 13 V/µs). Applications with high-impedance inputs or requiring fast transient response may not function correctly with the ADA4077. Consult application-specific circuit requirements before substitution.

Q: What inventory levels are available for each substitute part?

A: Current inventory levels are: TL074CPWR (31,027 units), TL084IPT (26,371 units), TL084CPT (12,870 units), ADA4077-4ARUZ (6,402 units), and ADA4077-4ARUZ-RL (5,818 units). Inventory levels are subject to change; verify current availability with your supplier.
