1. TL062IDT Substitution Conclusion The TL062IDT (STMicroelectronics) can fully replace the TL062CD (Texas Instruments). Both devices exhibit high consistency in core AC and DC parameters—such as J‑FET architecture, dual‑channel configuration, 1 MHz gain‑bandwidth product, 3.5 V/µs slew rate, and 30 pA input bias current—as well as in package (8‑SOIC), ensuring functional equivalence and pin‑to‑pin compatibility. The primary difference lies in the supply voltage range: the TL062CD is rated for 10 V to 30 V, while the TL062IDT extends this range to 6 V to 36 V. The wider range of the TL062IDT supports more flexible single‑supply or dual‑supply operation (e.g., ±3 V to ±18 V), offering better suitability for low‑voltage applications such as single‑supply 5 V systems. The higher voltage tolerance also enhances power‑supply flexibility. If the original design operates within 10 V–30 V, no performance deviation is expected after substitution. Should the wider voltage range be required, the TL062IDT may provide additional design margin.
