LM2902DR
ROHM
Needs validationhigh risk
LM2902DR is a slower quad SOIC-14 op amp and is only a downgrade-risk candidate.
Best Alternatives to TL074CDR
TL074CDR is a quad JFET-input SOIC-14 op amp. Listed substitutes need FAE review; none are confirmed pin-compatible here.
AI replacement insight
Electrical riskhigh
Slew, GBP, and input bias may differ.
Package riskmedium
SOIC-14 matches on two candidates only.
Firmware risklow
Analog op amp; no firmware expected.
Sourcing riskmedium
Kept candidates are NRND.
Can it be replaced directly?
No pin-compatible replacement is verified from the provided data.
Best replacement path
Look for an active quad JFET-input SOIC-14 op amp with verified TL074 pinout.
Main risk
Slow non-JFET op amps can fail audio, bias, and distortion requirements.
