Is there a pin-compatible replacement for TL082CDR?

Many dual op-amps in an SOIC-8 package, like TPA1882-SR, likely share a standard pinout. However, you must always verify the pin functions in the candidate's datasheet before replacement.

What risks should I check before replacing TL082CDR?

Key risks include mismatched supply voltage, lower slew rate or bandwidth, and different input stage technology (JFET vs. CMOS/Bipolar). Always verify the package and pinout are identical.

TL082CDR Alternatives, Datasheet & Cross Reference | Texas Instruments

The TL082CDR is a widely used dual JFET-input op-amp in a SOIC-8 package. When seeking alternatives, it's crucial to match the dual-channel configuration, supply voltage (5V-18V), and AC performance like slew rate (~13 V/µs).

AI replacement insight

Electrical riskmedium

Different input stage and higher bandwidth require circuit validation.

Package risklow

SOIC-8 is a standard package with a high likelihood of pinout compatibility.

Can it be replaced directly?

No direct, drop-in replacement was found in this batch. The closest candidate, TPA1882-SR, is a functional alternative that requires careful engineering review.

Best replacement path

Consider TPA1882-SR as a high-performance functional alternative, requiring engineering review for its zero-drift architecture and higher bandwidth.

Main risk

The primary risk is changing the amplifier's input architecture from JFET to a different type (like Zero-Drift), which can impact circuit stability and noise performance.
