Engineering Selection Recommendations

Primary Recommendation: TL074IDR

The TL074IDR (Texas Instruments) is the direct functional equivalent of the TL074IDE4. It maintains identical electrical specifications including 5.25 MHz gain bandwidth product, 13V/µs slew rate, 65 pA input bias current, and 10V to 30V supply voltage range. The TL074IDR is in Active product status with 25,400 units in stock, ensuring long-term availability. Both parts are ROHS3 compliant with MSL 1 rating. The primary difference is packaging format (Cut Tape & Digi-Reel versus the original packaging), which does not affect electrical performance or PCB assembly compatibility in 14-SOIC form factor.

Secondary Recommendation: TL074ID (STMicroelectronics)

The TL074ID provides J-FET amplifier functionality with four circuits in 14-SOIC packaging and Active product status. It accepts a wider supply voltage range (6V to 36V) compared to the TL074IDE4 (10V to 30V), providing greater design flexibility. The gain bandwidth product is reduced to 3 MHz, and input bias current is lower at 20 pA. Operating temperature range extends to 105°C. This part is suitable for applications where the lower gain bandwidth product is acceptable and extended temperature operation is required.

Alternative for Extended Temperature: LF247DT

The LF247DT (STMicroelectronics) offers J-FET amplifier type with four circuits and extended operating temperature to 105°C. It features a higher slew rate of 16V/µs and 4 MHz gain bandwidth product. The supply voltage specification is fixed at 44V (symmetric supply), which differs from the TL074IDE4. This part is appropriate for applications requiring higher slew rate performance and extended temperature operation within symmetric supply configurations.

Automotive-Grade Alternative: NCV33074DR2G

The NCV33074DR2G (onsemi) provides a general purpose amplifier alternative with four circuits in 14-SOIC packaging. It is AEC-Q100 qualified for automotive applications and maintains the 13V/µs slew rate of the original part. The supply voltage range is 3V to 44V, offering significantly wider operational envelope. Input bias current is higher at 100 nA, and input offset voltage is lower at 1 mV. This part is suitable for automotive applications where general purpose amplifier characteristics are acceptable.

Frequently Asked Questions (FAQ)

Q1: Can TL074IDR be used as a direct replacement for TL074IDE4?

Yes. The TL074IDR is electrically and functionally identical to the TL074IDE4. Both are J-FET amplifiers with four circuits, 5.25 MHz gain bandwidth product, 13V/µs slew rate, 65 pA input bias current, and 10V to 30V supply voltage range. The difference is packaging format (Cut Tape & Digi-Reel versus original packaging), which does not affect PCB assembly or electrical performance. Both are ROHS3 compliant with MSL 1 rating.

Q2: What is the difference between J-FET and General Purpose amplifier types in the substitute list?

J-FET amplifiers (TL074, LF247, LF347 series) feature extremely low input bias current (20-65 pA range) and are optimized for high-impedance signal sources. General Purpose amplifiers (NCV33074, SC2902) have higher input bias current (90-100 nA range) but offer wider supply voltage ranges and lower input offset voltage. Selection depends on application requirements for input impedance and signal source characteristics.

Q3: Why does the TL074ID have a lower gain bandwidth product (3 MHz) than the TL074IDE4 (5.25 MHz)?

The TL074ID is manufactured by STMicroelectronics and represents a different design variant within the TL074 base product family. While both are J-FET amplifiers with four circuits in 14-SOIC packaging, the STMicroelectronics version prioritizes lower input bias current (20 pA versus 65 pA) and wider supply voltage range (6V to 36V versus 10V to 30V) at the trade-off of reduced gain bandwidth product. Selection should be based on specific application requirements for frequency response versus input impedance characteristics.

Q4: Can LF247DT or LF347DT be used in place of TL074IDE4?

LF247DT and LF347DT are J-FET amplifiers with four circuits in 14-SOIC packaging and can serve as functional alternatives. However, they feature fixed symmetric supply voltage at 44V (not the 10V to 30V range of TL074IDE4), higher slew rate (16V/µs), and lower gain bandwidth product (3-4 MHz). These parts are suitable only for applications with symmetric supply configurations and where the different frequency response is acceptable.

Q5: What is the significance of Product Status (Active versus Obsolete)?

Active status indicates the manufacturer continues production and supports long-term availability. Obsolete status indicates the manufacturer has discontinued production. The TL074IDE4 is obsolete, making substitution necessary for new designs or ongoing procurement. All recommended substitutes (TL074IDR, TL074ID, LF247DT, LF347DT, NCV33074DR2G, SC2902DG) are in Active status, ensuring continued availability and manufacturer support.

Q6: Are all substitute parts ROHS3 compliant?

Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the TL074IDE4. This ensures compatibility with modern manufacturing processes and environmental regulations.

Q7: Which substitute part offers the widest supply voltage range?

The NCV33074DR2G and SC2902DG offer the widest supply voltage range (3V to 44V and 3V to 32V respectively), compared to the TL074IDE4 (10V to 30V). These general purpose amplifiers provide greater design flexibility for applications requiring operation across extended supply voltage ranges.

Q8: What is the difference between Cut Tape & Digi-Reel and Tube packaging?

Cut Tape & Digi-Reel packaging is supplied on continuous tape suitable for automated pick-and-place assembly equipment. Tube packaging is supplied in plastic tubes for manual handling or older assembly processes. Both formats contain identical components; the difference is in delivery and handling method. Selection depends on manufacturing process requirements.
