Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL082AIPT is determined by the following critical parameters:

Functional Compatibility Criteria:

• Amplifier Type: J-FET input topology
• Number of Circuits: Dual-channel (2 circuits)
• Package / Case: 8-TSSOP form factor with 0.173" width and 4.40mm width specification
• Mounting Type: Surface Mount

Electrical Operating Range Criteria:

• Supply Voltage Range: Minimum 6V to Maximum 36V
• Operating Temperature Range: -40°C to 105°C
• Input Bias Current: 20 pA or lower
• Input Offset Voltage: 3 mV or lower
• Output Current per Channel: 40 mA or higher

Compliance and Certification Criteria:

• Automotive Grade qualification
• AEC-Q100 certification
• RoHS3 compliance
• MSL Level 1 (Unlimited)

Substitute parts must satisfy all functional compatibility criteria and maintain electrical performance within the specified operating ranges. Parts that deviate from the supply voltage range, operating temperature span, or package specification are not direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TL082IPWR

The TL082IPWR is the recommended substitute for the TL082AIPT. Both parts share identical J-FET amplifier topology, dual-channel configuration, and 8-TSSOP packaging. The TL082IPWR maintains equivalent electrical specifications including 30 pA input bias current, 3 mV input offset voltage, and 1.4 mA supply current. The TL082IPWR operates across -40°C to 85°C, which encompasses the lower portion of the TL082AIPT's operating range (-40°C to 105°C). The TL082IPWR is currently in active production status, ensuring long-term availability. Both parts are RoHS3 compliant with MSL Level 1 rating.

Secondary Substitute: TL082CPWR

The TL082CPWR is an active production alternative with identical electrical characteristics to the TL082IPWR. The TL082CPWR operates across 0°C to 70°C, which is narrower than the TL082AIPT's range. This part is suitable for applications where the full automotive temperature range is not required. The TL082CPWR is available in Cut Tape (CT) & Digi-Reel® packaging, differing from the TL082AIPT's Tape & Reel (TR) format.

Tertiary Substitute: TL072CPWR

The TL072CPWR is an active production J-FET dual-channel amplifier in 8-TSSOP packaging. This part exhibits higher gain bandwidth product (5.25 MHz versus 4 MHz) and higher input bias current (65 pA versus 20 pA). The TL072CPWR operates across 0°C to 70°C, which does not meet the full automotive temperature specification of the TL082AIPT. This part is suitable only for applications where the reduced temperature range is acceptable.

Non-Recommended Substitute: RC4580QPWRQ1

The RC4580QPWRQ1 is an audio amplifier topology, not a J-FET amplifier. Although it maintains AEC-Q100 automotive qualification and operates across -40°C to 125°C, the fundamental amplifier type differs from the TL082AIPT. The RC4580QPWRQ1 exhibits significantly higher supply current (6 mA versus 1.4 mA) and lower slew rate (5 V/µs versus 16 V/µs). This part is not a functional equivalent.

Obsolete Parts: TL072CPWRG4 and TL082CPW

Both TL072CPWRG4 and TL082CPW are classified as obsolete. While TL082CPW shares identical electrical specifications with TL082CPWR, its obsolete status makes it unsuitable for new designs or long-term procurement strategies.

Frequently Asked Questions (FAQ)

Q: Can the TL082IPWR directly replace the TL082AIPT in all applications?

A: The TL082IPWR is electrically equivalent to the TL082AIPT across all specified parameters. However, the TL082IPWR operates across -40°C to 85°C, while the TL082AIPT operates to 105°C. Applications requiring operation above 85°C require thermal analysis to confirm suitability. Both parts are RoHS3 compliant with identical MSL ratings and 8-TSSOP packaging.

Q: What is the difference between TL082CPWR and TL082IPWR?

A: Both parts are J-FET dual-channel amplifiers with identical electrical specifications. The primary difference is operating temperature range: TL082CPWR operates 0°C to 70°C, while TL082IPWR operates -40°C to 85°C. The TL082IPWR is suitable for automotive applications requiring extended low-temperature operation. Packaging format differs: TL082CPWR uses Cut Tape (CT) & Digi-Reel®, while TL082IPWR uses Tape & Reel (TR).

Q: Why is the RC4580QPWRQ1 not recommended as a substitute?

A: The RC4580QPWRQ1 is an audio amplifier, not a J-FET amplifier. This fundamental topology difference results in different electrical characteristics: 100 nA input bias current (versus 20 pA), 500 µV input offset voltage (versus 3 mV), and 6 mA supply current (versus 1.4 mA). These differences make it unsuitable for applications designed around J-FET amplifier specifications.

Q: Are all substitute parts automotive qualified?

A: Only the TL082IPWR and RC4580QPWRQ1 carry automotive grade designation with AEC-Q100 qualification. The TL072CPWR and TL072CPWRG4 do not carry automotive qualification. For automotive applications, the TL082IPWR is the appropriate substitute.

Q: What is the significance of the 8-TSSOP package specification?

A: The 8-TSSOP package is a surface mount thin shrink small outline package with 0.173" width and 4.40mm width specification. All listed substitute parts use identical 8-TSSOP packaging, ensuring mechanical and electrical compatibility with existing PCB layouts. Packaging format (Tape & Reel, Cut Tape, or Tube) affects procurement and handling but does not affect electrical performance.

Q: Can the TL072CPWR be used in place of the TL082AIPT?

A: The TL072CPWR shares J-FET topology and dual-channel configuration in 8-TSSOP packaging. However, it exhibits higher input bias current (65 pA versus 20 pA), operates across 0°C to 70°C (narrower than -40°C to 105°C), and lacks automotive qualification. Use of TL072CPWR requires circuit redesign validation and is suitable only for non-automotive applications with reduced temperature requirements.

Q: What does "obsolete" product status mean for the TL082AIPT?

A: Obsolete status indicates the TL082AIPT is no longer in active production. Existing inventory may be available from distributors, but long-term procurement cannot be guaranteed. Active production substitutes such as TL082IPWR or TL082CPWR ensure continued availability for new designs and ongoing production requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. This ensures compatibility with modern manufacturing processes and environmental regulations.
