AI replacement insight
Electrical riskhigh
JFET bias and current ranges are not close.
Package riskmedium
Package text matches, pinout is unverified.
Firmware risklow
Discrete JFET has no firmware.
Sourcing riskmedium
Most listed candidates are wrong device type.
Can it be replaced directly?
No verified pin-compatible replacement is identified.
Best replacement path
Review MMBFJ112 only as a relaxed-parameter N-JFET candidate.
Main risk
JFET electrical ranges differ, especially VDG, VGS(off), and IDSS.
