Number of Circuits: 2 (dual-channel configuration)
Package / Case: 8-SOIC surface mount form factor
Slew Rate: 3.5 V/µs (signal fidelity requirement)
Gain Bandwidth Product: 1 MHz (frequency response specification)
Current - Input Bias: 30 pA (low-bias requirement)
Voltage - Input Offset: 3 mV (offset specification)

Frequently Asked Questions (FAQ)

Q1: Can I use TL062CDR as a direct replacement for TL062CDRE4?

A: Yes. The TL062CDR is manufactured by Texas Instruments and provides identical electrical specifications, including J-FET amplifier type, dual-circuit configuration, slew rate (3.5 V/µs), gain bandwidth product (1 MHz), input bias current (30 pA), input offset voltage (3 mV), and output current (20 mA per channel). Both operate within 0°C to 70°C temperature range. The primary difference is product status: TL062CDRE4 is discontinued while TL062CDR is active with substantial inventory (130,300 units). Both are ROHS3 compliant with MSL Level 1.

Q2: What is the difference between TL062CDT and TL062CDRE4?

A: The TL062CDT is manufactured by STMicroelectronics and provides identical electrical specifications to TL062CDRE4 in terms of amplifier type, circuit count, slew rate, bandwidth, and input/output characteristics. The key difference is the extended supply voltage range: TL062CDT operates from 6 V to 36 V, while TL062CDRE4 operates from 10 V to 30 V. This extended range makes TL062CDT suitable for applications with lower or higher supply voltages. TL062CDT is active with 147,200 units in stock.

Q3: Should I use TL062IDT if my application requires extended temperature operation?

A: Yes, if your application requires operation beyond the standard 0°C to 70°C range. The TL062IDT provides identical electrical specifications to TL062CDRE4 but extends the operating temperature range to -40°C to 105°C. This makes it suitable for industrial, automotive, and environmental applications requiring broader temperature tolerance. TL062IDT is active with 7,100 units in stock and is ROHS3 compliant.

Q4: Can I substitute TL072CDT for TL062CDRE4?

A: TL072CDT is not recommended as a direct substitute for most applications. While both are J-FET amplifiers in 8-SOIC packages with dual-circuit configuration, TL072CDT has significantly different performance specifications: slew rate of 16 V/µs (vs. 3.5 V/µs), gain bandwidth product of 4 MHz (vs. 1 MHz), and output current of 40 mA per channel (vs. 20 mA). Additionally, TL072CDT has higher supply current (1.4 mA vs. 200 µA), which may impact power-sensitive designs. TL072CDT is suitable only for applications where higher bandwidth and slew rate are required and increased power consumption is acceptable. TL072CDT is automotive-grade and AEC-Q100 qualified.

Q5: Why is LM833DT listed as a substitute if it has different input characteristics?

A: LM833DT is classified as a functional alternative rather than a direct substitute. It provides the same dual-circuit configuration in an 8-SOIC package but uses audio amplifier architecture instead of J-FET. This results in fundamentally different input bias current (300 nA vs. 30 pA) and input offset voltage (300 µV vs. 3 mV). LM833DT is suitable only for applications where these audio amplifier specifications are acceptable and where the higher bandwidth (15 MHz) and slew rate (7 V/µs) provide benefit. Substitution requires application-specific verification and is not recommended for designs dependent on J-FET input characteristics.

Q6: What packaging options are available for these substitutes?

A: All listed substitutes are available in 8-SOIC (0.154", 3.90mm width) surface mount package, matching the TL062CDRE4 form factor. Packaging options vary by part number: TL062CDR is available in Cut Tape (CT) and Digi-Reel; TL062CDT, LM833DT, TL062ACDT, TL062IDT, and TL072CDT are available in Cut Tape (CT) and Digi-Reel; TL062BCDT is available in Tape & Reel (TR). All parts are MSL Level 1 (Unlimited moisture sensitivity).

Q7: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts (TL062CDR, TL062CDT, LM833DT, TL062ACDT, TL062BCDT, TL062IDT, and TL072CDT) are ROHS3 compliant and have MSL Level 1 rating. All are REACH unaffected and classified under ECCN EAR99 with HTSUS code 8542.33.0001, matching the regulatory status of TL062CDRE4.

Q8: Which substitute has the best inventory availability?

A: TL072CDT has the highest inventory with 203,200 units in stock, followed by LM833DT with 166,607 units and TL062CDT with 147,200 units. TL062CDR has 130,300 units. If inventory availability is a critical factor and performance specifications are compatible with your application, TL072CDT offers the largest supply buffer. However, verify that the enhanced performance specifications (higher bandwidth, slew rate, and supply current) are acceptable for your design.

Q9: What is the minimum supply voltage for each substitute?

A: TL062CDRE4 requires a minimum of 10 V. Most substitutes (TL062CDT, LM833DT, TL062ACDT, TL062BCDT, TL062IDT, TL072CDT) operate from a minimum of 6 V, providing greater flexibility for lower-voltage applications. TL062CDR maintains the 10 V minimum. If your application uses supply voltages between 6 V and 10 V, select from the substitutes with 6 V minimum rating.

Q10: Which substitute is recommended for automotive applications?

A: TL072CDT is the only substitute with automotive-grade qualification and AEC-Q100 certification. If your application requires automotive-grade components, TL072CDT is the appropriate choice. However, verify that its enhanced performance specifications (16 V/µs slew rate, 4 MHz bandwidth, 1.4 mA supply current) are compatible with your design requirements, as these differ significantly from TL062CDRE4.
