Is there a pin-compatible replacement for LM258DT?

Yes, parts like TSH22IDT and TSB7192IDT are available in the same SO8 package and are expected to be pin-compatible with the standard dual op-amp layout. However, it is critical to verify the pinout from the datasheet before board assembly.

What risks should I check before replacing LM258DT?

Key risks include: 1) Supply Voltage: Ensure the replacement supports your circuit's voltage (target is 3-30V). 2) Temperature Range: Match the industrial range (-40 to 105°C) if needed. 3) Stability: Higher bandwidth replacements may cause oscillation in circuits not designed for them.
