STMicroelectronics lists the TL084CN as obsolete. Sourcing now runs through independent distribution, where date-code provenance and lot traceability become the buyer's own risk to manage. For new designs or a production respin, evaluate a currently-manufactured JFET quad op-amp in a surface-mount package with a DIP adapter, or a through-hole alternative that meets the supply and bandwidth requirements.
Yes, STMicroelectronics lists the TL084CN as obsolete. There is no official last-time-buy or direct successor from the manufacturer.
The TL084CN and TL084CD share the same JFET quad op-amp core, but the CN suffix indicates the 14-DIP through-hole package, while the CD suffix is the SOIC-14 surface-mount variant. Electrical specs — 3 MHz GBW, 13 V/µs slew rate, 30 pA bias — are identical. The choice is purely a board-assembly and footprint decision.
No official cross-reference document exists from STMicroelectronics. Functionally, the TL084 family is widely second-sourced by Texas Instruments (TL084ACN, TL084BCN) and others, but those parts are also obsolete or NRND. For a currently-manufactured JFET quad op-amp, the Texas Instruments TLV9362IDDFR (dual, surface-mount) or OPA4374AIPWT (quad CMOS, rail-to-rail) are active alternatives but differ in package, supply range, and output swing.
