Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

The TL062CDR (Texas Instruments) is the primary direct equivalent to the TL062CDRG4. Both parts share identical electrical specifications, supply voltage range (10 V to 30 V), and operating temperature range (0°C to 70°C). The TL062CDR is currently active with significantly higher inventory availability (130,300 pieces), making it the preferred choice for immediate supply requirements and design continuity.

For Extended Supply Voltage Range Applications:

The TL062CDT, TL062ACDT, and TL062BCDT (all STMicroelectronics) provide identical J-FET amplifier performance with an extended supply voltage range (6 V to 36 V minimum to maximum). These parts are suitable for applications requiring lower minimum supply voltages or higher maximum supply voltages than the original TL062CDRG4 specification. All three variants are currently active with substantial inventory levels.

The TL062BCDT offers the tightest input offset voltage specification (2 mV versus 3 mV), providing improved precision for offset-sensitive applications while maintaining all other electrical parameters.

For Extended Temperature Range Applications:

The TL062IDT (STMicroelectronics) extends the operating temperature range to -40°C to 105°C while maintaining identical electrical specifications and the extended supply voltage range (6 V to 36 V). This variant is suitable for industrial and automotive temperature environments.

For Enhanced Performance Requirements:

The TL072CDT (STMicroelectronics) provides superior performance characteristics: 16 V/µs slew rate (4.6× improvement), 4 MHz gain bandwidth product (4× improvement), and 40 mA output current per channel (2× improvement). The TL072CDT maintains J-FET input architecture and dual-channel configuration in 8-SOIC packaging. This part is suitable for applications requiring higher bandwidth, faster transient response, or higher output drive capability. The TL072CDT carries AEC-Q100 automotive qualification and is available in high volume (203,200 pieces).

For Alternative Amplifier Architecture:

The LM833DT (STMicroelectronics) is an audio amplifier with dual-channel configuration in 8-SOIC packaging. This part features significantly different electrical characteristics: 7 V/µs slew rate, 15 MHz gain bandwidth product, 300 nA input bias current, and 4 mA supply current. The LM833DT is suitable only for applications where the audio amplifier architecture is compatible with the design requirements and where the higher input bias current and lower input offset voltage (0.3 mV) are acceptable trade-offs.

All recommended substitute parts maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and REACH unaffected status, consistent with the original TL062CDRG4.

Frequently Asked Questions (FAQ)

Q1: Can the TL062CDR directly replace the TL062CDRG4 in existing designs?

A: Yes. The TL062CDR is electrically and mechanically identical to the TL062CDRG4. Both parts feature identical J-FET amplifier specifications, dual-channel configuration, 8-SOIC packaging, and operating parameters (0°C to 70°C, 10 V to 30 V supply range). The primary difference is product status: TL062CDR is active with high availability, while TL062CDRG4 is discontinued.

Q2: What is the difference between TL062CDT and TL062ACDT?

A: Both parts are STMicroelectronics J-FET dual-channel amplifiers in 8-SOIC packaging with identical electrical specifications. The primary difference is the input bias current specification: TL062CDT specifies 30 pA, while TL062ACDT specifies 30 nA (1000× higher). For applications sensitive to input bias current, TL062CDT is the preferred choice. Both parts feature extended supply voltage range (6 V to 36 V).

Q3: Why does TL062BCDT specify 2 mV input offset voltage instead of 3 mV?

A: TL062BCDT represents a tighter grade variant of the TL062 family with improved input offset voltage specification (2 mV maximum versus 3 mV). All other electrical parameters remain identical. This variant is suitable for precision analog applications where lower input offset voltage is required.

Q4: Is the TL072CDT a suitable substitute for the TL062CDRG4?

A: The TL072CDT is a compatible substitute only if the application can accommodate enhanced performance characteristics. The TL072CDT provides 4.6× higher slew rate (16 V/µs versus 3.5 V/µs), 4× higher gain bandwidth product (4 MHz versus 1 MHz), and 2× higher output current (40 mA versus 20 mA). Both parts use J-FET input architecture and dual-channel configuration in 8-SOIC packaging. The TL072CDT is suitable for applications requiring higher bandwidth or faster transient response. However, the higher supply current (1.4 mA versus 200 µA) must be considered in power-constrained designs.

Q5: Can the LM833DT replace the TL062CDRG4?

A: The LM833DT is not a direct substitute. While both parts feature dual-channel configuration in 8-SOIC packaging, the LM833DT uses audio amplifier architecture instead of J-FET input architecture. The LM833DT has significantly different electrical characteristics: 300 nA input bias current (10,000× higher), 0.3 mV input offset voltage (lower), 7 V/µs slew rate, and 15 MHz gain bandwidth product. The LM833DT is suitable only for applications where audio amplifier architecture is compatible with design requirements.

Q6: What is the supply voltage compatibility between TL062CDRG4 and STMicroelectronics TL062 variants?

A: The TL062CDRG4 specifies a supply voltage range of 10 V to 30 V. STMicroelectronics TL062 variants (TL062CDT, TL062ACDT, TL062BCDT, TL062IDT) specify an extended range of 6 V to 36 V. This means STMicroelectronics parts can operate at lower minimum voltages (6 V versus 10 V) and higher maximum voltages (36 V versus 30 V). For applications operating within the original 10 V to 30 V range, both part families are compatible.

Q7: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (TL062CDR, TL062CDT, TL062ACDT, TL062BCDT, TL062IDT, TL072CDT, LM833DT) are ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity) and REACH unaffected status, consistent with the original TL062CDRG4.

Q8: Which substitute part offers the best availability?

A: The TL072CDT offers the highest inventory availability with 203,200 pieces in stock. For direct TL062 family equivalents, the TL062CDR provides the highest availability (130,300 pieces) among active parts. The original TL062CDRG4 has 2,860 pieces remaining as discontinued stock.

Q9: What is the operating temperature range difference between TL062CDT and TL062IDT?

A: The TL062CDT operates over 0°C to 70°C, while the TL062IDT extends the range to -40°C to 105°C. Both parts maintain identical electrical specifications and extended supply voltage range (6 V to 36 V). The TL062IDT is suitable for industrial and automotive applications requiring extended temperature operation.

Q10: Can I use TL062CDT in a design originally specified for TL062CDRG4 without circuit modifications?

A: Yes, with one consideration. The TL062CDT has an extended supply voltage range (6 V to 36 V versus 10 V to 30 V). If your circuit operates within the original 10 V to 30 V range, the TL062CDT is a direct substitute with no circuit modifications required. The 8-SOIC package dimensions are identical, and all electrical specifications within the overlapping voltage range are equivalent.
