TL082CP/PB Equivalent & Substitute Parts

Part Overview

The TL082CP/PB is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-DIP through-hole package. This part is classified as obsolete, though 1107 pieces remain in new original stock. The TL082CP/PB operates across a 36V supply span with a slew rate of 13V/µs and gain bandwidth product of 4 MHz, making it suitable for precision analog signal processing applications requiring low input bias current (50 pA) and moderate input offset voltage (5 mV).

Due to its obsolete status, identifying equivalent and substitute parts is necessary for design continuity, production planning, and long-term component availability assurance. Active alternatives within the TL082 family and cross-manufacturer options provide functional equivalence with varying performance characteristics and supply availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TL082CP/PB is determined by the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type (J-FET vs. General Purpose)
• Number of Circuits (dual-channel configuration)
• Package / Case (8-DIP through-hole form factor)
• Voltage - Supply Span compatibility
• Slew Rate and Gain Bandwidth Product performance envelope
• Current - Input Bias and Voltage - Input Offset specifications

Substitution Groups:

Group 1: Direct TL082 Family Variants (Texas Instruments) Parts TL082ACP, TL082BCP, and TL082CP share identical package, mounting type, and J-FET amplifier architecture. These variants differ in performance grades (input bias current, input offset voltage) and supply span specifications. TL082CP/NOPB is a lead-free variant with identical electrical specifications to TL082CP/PB.

Group 2: Cross-Manufacturer Alternative (Renesas Electronics) The CA3240EZ represents a functional alternative with different amplifier type (General Purpose vs. J-FET), broader operating temperature range, and different electrical characteristics. This part maintains 8-DIP package compatibility and dual-channel configuration but operates across a wider supply span (4V to 36V minimum/maximum).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (TL082 Family):

TL082CP is the primary active substitute, offering identical electrical specifications to TL082CP/PB with the exception of supply span (10V to 30V vs. 36V fixed). This part maintains J-FET amplifier type, dual-channel configuration, and 8-DIP package compatibility. With 10,300 pieces in stock, TL082CP provides superior long-term availability compared to the obsolete TL082CP/PB.

TL082CP/NOPB is a lead-free variant with identical specifications to TL082CP/PB, including 36V supply span and 4 MHz gain bandwidth product. This part is suitable for applications requiring RoHS compliance with lead-free solder processing.

TL082ACP and TL082BCP offer improved input bias current (30 pA) and input offset voltage specifications (3 mV and 2 mV respectively) with reduced supply current (1.4 mA vs. 3.6 mA). These variants operate across 10V to 30V supply span and are suitable for low-power, precision applications. TL082BCP provides the lowest input offset voltage (2 mV) among TL082 variants.

For Cross-Manufacturer Substitution (CA3240EZ):

The CA3240EZ from Renesas Electronics Corporation is a General Purpose amplifier alternative with broader operating temperature range (-40°C to 85°C) and extended supply span (4V to 36V). This part maintains 8-DIP package and dual-channel configuration. The CA3240EZ exhibits superior input bias current (10 pA) and higher output current capability (40 mA per channel). However, the CA3240EZ operates at lower slew rate (9V/µs vs. 13V/µs) and higher supply current (8 mA vs. 3.6 mA). Selection of CA3240EZ is appropriate for applications requiring extended temperature operation or lower input bias current, with acceptance of increased power consumption.

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with TL082CP/PB.

Frequently Asked Questions (FAQ)

Q: Can TL082CP directly replace TL082CP/PB in all applications?

A: TL082CP is electrically compatible for applications operating within 10V to 30V supply span. The TL082CP/PB operates at a fixed 36V supply span. If your circuit requires 36V operation, TL082CP/NOPB (lead-free variant) or TL082CP/PB itself must be used. For circuits operating within the 10V to 30V range, TL082CP provides identical J-FET amplifier performance with superior stock availability.

Q: What is the difference between TL082ACP, TL082BCP, and TL082CP?

A: All three are J-FET dual-channel amplifiers in 8-DIP packages. TL082ACP and TL082BCP are lower-grade variants with improved input bias current (30 pA vs. 50 pA) and lower input offset voltage (3 mV and 2 mV respectively). TL082BCP offers the tightest input offset voltage specification (2 mV). All three operate across 10V to 30V supply span with reduced supply current (1.4 mA vs. 3.6 mA). Selection depends on precision requirements and power budget constraints.

Q: Is CA3240EZ a suitable replacement for TL082CP/PB?

A: CA3240EZ is functionally compatible in 8-DIP package and dual-channel configuration. However, it is a General Purpose amplifier, not J-FET type. The CA3240EZ operates across 4V to 36V supply span with superior input bias current (10 pA) and extended temperature range (-40°C to 85°C). Trade-offs include lower slew rate (9V/µs vs. 13V/µs) and higher supply current (8 mA vs. 3.6 mA). CA3240EZ is suitable for applications prioritizing low input bias current and extended temperature operation over slew rate performance.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed (TL082ACP, TL082BCP, TL082CP, TL082CP/NOPB, and CA3240EZ) are ROHS3 compliant. TL082CP/NOPB is specifically designated as lead-free for applications requiring lead-free solder processing.

Q: What is the difference between TL082CP/PB and TL082CP/NOPB?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications (J-FET amplifier, 2 circuits, 13V/µs slew rate, 4 MHz gain bandwidth product, 36V supply span). The primary difference is packaging: TL082CP/PB uses traditional lead-based solder, while TL082CP/NOPB is a lead-free variant. Both maintain ROHS3 compliance and are suitable for direct substitution based on soldering process requirements.

Q: Which substitute offers the lowest power consumption?

A: TL082ACP and TL082BCP offer the lowest supply current at 1.4 mA (x2 channels), compared to 3.6 mA for TL082CP/PB and TL082CP/NOPB, and 8 mA for CA3240EZ. Selection of TL082ACP or TL082BCP is appropriate for battery-powered or low-power applications, provided the 10V to 30V supply span and 3 MHz gain bandwidth product meet circuit requirements.

Q: Can I use CA3240EZ in a circuit designed for TL082CP/PB?

A: CA3240EZ is mechanically and functionally compatible (8-DIP package, dual-channel, 2 circuits). However, electrical differences must be evaluated: CA3240EZ has lower slew rate (9V/µs vs. 13V/µs), higher supply current (8 mA vs. 3.6 mA), and different amplifier type (General Purpose vs. J-FET). Circuits sensitive to slew rate performance or power consumption may require design verification before substitution.
