TL082CM Equivalent & Substitute Parts

Part Overview

The TL082CM is a J-FET input operational amplifier containing two independent circuits in an 8-SOIC surface mount package, manufactured by Texas Instruments. This device is classified as obsolete and is no longer in active production. The TL082CM operates across a supply voltage span of 36 V with a slew rate of 13 V/µs and a gain bandwidth product of 4 MHz, making it suitable for general-purpose analog signal processing applications requiring low input bias current and low input offset voltage characteristics.

Due to its obsolete status, component sourcing for new designs requires identification of functionally equivalent alternatives that maintain electrical compatibility while offering improved availability, compliance status, or enhanced performance characteristics. Substitute parts must maintain the same amplifier topology (J-FET input), circuit count (2 circuits), package form factor (8-SOIC), and operating temperature range to ensure direct functional replacement.

Engineering Selection Recommendations

For Direct Replacement (Electrical Compatibility):

The TL082ACDR and TL082CDR represent the primary substitutes for the TL082CM. Both devices maintain the J-FET input topology, dual-circuit configuration, and 8-SOIC package form factor. The TL082ACDR is manufactured by Texas Instruments with active product status, ensuring long-term availability and supply chain stability. The TL082CDR is also actively produced by Texas Instruments and offers identical electrical specifications to the TL082ACDR.

For Enhanced Compliance Requirements:

Applications requiring RoHS3 compliance should specify either TL082ACDR, TL082CDR, or TL082CD. All three devices meet RoHS3 compliance standards, whereas the original TL082CM is RoHS non-compliant. The TL082CD, manufactured by STMicroelectronics, offers the additional advantage of automotive-grade qualification (AEC-Q100) and extended supply voltage range (6 V to 36 V minimum), providing superior performance margin in applications with variable supply conditions.

For Extended Temperature Range Applications:

The TL082IDR extends the operating temperature range to -40°C to 85°C, accommodating industrial and military-grade applications requiring operation beyond the standard 0°C to 70°C range. This device maintains active production status and ROHS3 compliance.

For Enhanced Performance Characteristics:

The TLE2082ACDR provides superior performance with a slew rate of 40 V/µs, gain bandwidth product of 10 MHz, and output current capability of 48 mA per channel. This device is suitable for applications requiring higher bandwidth and faster transient response than the original TL082CM specification. The TLE2082ACDR maintains active production status and ROHS3 compliance.

For Last Time Buy Scenarios:

The TL082ACPSR and TL082CPSR are designated as Last Time Buy parts with limited remaining inventory. These devices should be selected only when existing design documentation specifically requires these part numbers or when inventory depletion of primary alternatives necessitates transition planning.

Frequently Asked Questions (FAQ)

Q: Can the TL082CM be directly replaced with the TL082ACDR in existing designs?

A: Yes. The TL082ACDR maintains electrical compatibility with the TL082CM through identical J-FET input topology, dual-circuit configuration, and 8-SOIC package form factor. The TL082ACDR offers improved input bias current (30 pA versus 50 pA) and lower input offset voltage (3 mV versus 5 mV), making it a superior direct replacement. The primary difference is the reduced supply voltage span (10 V to 30 V versus 36 V), which must be verified against the application's power supply design.

Q: What is the difference between TL082ACDR and TL082CDR?

A: Both devices are manufactured by Texas Instruments and offer identical electrical specifications. The primary distinction is packaging: TL082ACDR is supplied in Cut Tape (CT) & Digi-Reel format, while TL082CDR is supplied in the same format. Both maintain active production status and ROHS3 compliance. Selection between these parts is determined by procurement and assembly requirements rather than electrical performance.

Q: Why does the TL082CD have a lower minimum supply voltage (6 V) compared to other TL082 variants?

A: The TL082CD is manufactured by STMicroelectronics and incorporates design optimizations that permit operation at lower supply voltages while maintaining specified performance characteristics. This extended supply voltage range (6 V to 36 V) provides additional design flexibility for applications with variable or constrained power supply conditions. The TL082CD also carries automotive-grade qualification (AEC-Q100), indicating enhanced reliability screening and process controls.

Q: Is the TLE2082ACDR a suitable substitute for the TL082CM?

A: The TLE2082ACDR is functionally compatible but represents an enhanced performance variant rather than a direct equivalent. It maintains the J-FET input topology, dual-circuit configuration, and 8-SOIC package. However, the TLE2082ACDR offers significantly higher slew rate (40 V/µs versus 13 V/µs), greater gain bandwidth product (10 MHz versus 4 MHz), and higher output current capability (48 mA versus 17 mA). These enhanced characteristics make the TLE2082ACDR suitable for applications requiring higher bandwidth and faster transient response. Substitution is appropriate when the application can tolerate or benefit from these performance improvements.

Q: What is the significance of the RoHS3 compliance designation?

A: RoHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive, which restricts the use of specific hazardous materials in electrical and electronic equipment. The original TL082CM is RoHS non-compliant, whereas all recommended substitutes (TL082ACDR, TL082CDR, TL082CD, TL082IDR, and TLE2082ACDR) are ROHS3 compliant. For applications subject to regulatory requirements or customer specifications mandating RoHS compliance, selection of ROHS3-compliant alternatives is mandatory.

Q: Can the TL082IDR be used in applications requiring only 0°C to 70°C operation?

A: Yes. The TL082IDR is fully compatible with applications requiring the standard 0°C to 70°C operating temperature range. The extended temperature range (-40°C to 85°C) represents an additional capability that does not restrict operation within the narrower temperature band. The TL082IDR maintains active production status, ROHS3 compliance, and identical electrical specifications to other TL082 variants within the standard temperature range.

Q: What packaging options are available for TL082 substitutes?

A: TL082 substitutes are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel (TL082ACDR, TL082BCDR, TL082CDR), Tape & Reel (TL082ACPSR, TL082CPSR, TLE2082ACDR), and Tube (TL082BCD, TL082CD). Selection of packaging format is determined by assembly process requirements and procurement volume. All variants maintain the 8-SOIC (0.154", 3.90mm Width) or 8-SO (0.209", 5.30mm Width) surface mount package form factor.

Q: Are there any performance trade-offs when substituting the TL082CM with lower-cost alternatives?

A: Substitution with TL082ACDR, TL082CDR, or TL082CD results in improved performance characteristics: reduced input bias current, lower input offset voltage, and lower supply current consumption. These improvements represent performance enhancements rather than trade-offs. The primary design consideration is the reduced maximum supply voltage span (30 V versus 36 V) for most TL082 variants, which must be evaluated against the application's power supply design. Applications requiring the full 36 V supply span should specify the TL082CD (STMicroelectronics) or TL082ACD, which maintain the extended supply voltage range.
