Is there a pin-compatible replacement for TL082CDT?

Several dual op-amps like TS512AIDT share the same SO-8 package and standard pinout. However, they are not electrically equivalent due to differences in slew rate and input bias current, so they are not drop-in replacements.

What risks should I check before replacing TL082CDT?

Key risks include: 1) Mismatched input type (Bipolar vs. JFET) causing higher input bias current, 2) Lower slew rate affecting signal integrity, and 3) Different supply voltage ranges that may not be compatible with your power rails.

TL082CDT Alternatives, Datasheet & Cross Reference | STMicroelectronics

The TL082CDT is a popular dual JFET op-amp known for its high slew rate and low input bias. Finding a replacement requires careful matching of these key parameters, especially the JFET input characteristic.

AI replacement insight

Electrical riskhigh

Major differences in slew rate, input bias current, and supply voltage across all candidates.

Package risklow

Candidates share the common SO-8 package, but pinout requires verification.

Can it be replaced directly?

No direct, drop-in replacement for the TL082CDT was found. All candidates present significant parametric differences requiring engineering review.

Best replacement path

Consider a functional alternative like TS512AIDT, but verify the impact of its much lower slew rate and higher input bias current.

Main risk

The primary risk is substituting the JFET input of the TL082CDT with a Bipolar input amplifier, which dramatically increases input bias current.

Recommended alternatives

A dual op-amp in the same package, but with lower performance and a different supply range.
