Is there a pin-compatible replacement for TL084CDR?

The TP2584-SR is available in the same SOIC-14 package, but its pinout must be manually verified against the TL084CDR datasheet to confirm pin-for-pin compatibility. No pre-verified pin-compatible replacement is available.

What risks should I check before replacing TL084CDR?

Key risks include: 1) Supply Voltage: Ensure the replacement supports up to 36V (or ±18V). 2) Slew Rate: The TL084CDR has a high slew rate (13V/µs); a slower part may cause distortion. 3) Input Bias Current: As a JFET amp, it has very low input current; ensure the replacement is comparable. 4) Pinout: Always verify the pinout is identical.

The TL084CDR is a popular quad JFET-input op-amp from Texas Instruments in a SOIC-14 package, known for its high slew rate. Finding a replacement requires matching its high supply voltage and dynamic performance.

AI replacement insight

Electrical riskmedium

Lower slew rate and unverified offset voltage may affect circuit performance.

Package risklow

Package is a standard SOIC-14, but pinout requires verification.

Sourcing riskmedium

Candidate is from a different, less common manufacturer than the target.

Can it be replaced directly?

No direct, drop-in replacement was found. The TP2584-SR is a functional match but has a lower slew rate. Pinout and other key parameters must be verified from the datasheet.

Best replacement path

Consider TP2584-SR as a potential functional alternative, but verify its lower slew rate is acceptable for your application.

Main risk

The primary risk is performance degradation, specifically the slew rate. Many proposed alternatives have incompatible, much lower supply voltage ratings.

Recommended alternatives

A functional alternative in a matching SOIC-14 package with a wider temperature range, but has a lower slew rate.
