A pin-compatible upgrade from the same family with a wider operating temperature range.
The TL074CDT is a popular low-noise JFET quad op-amp. When searching for replacements, focus on JFET-input amplifiers with a similar 3 MHz bandwidth and SO14 package.
Low when using the TL074IDT. High if considering other op-amp families due to voltage and input current differences.
SO14 is a standard package, ensuring mechanical compatibility.
Yes, the TL074IDT is a direct, pin-compatible replacement for the TL074CDT, offering a wider temperature range.
The most reliable replacement is the TL074IDT, which is a direct upgrade in temperature range within the same product family.
The main risk when substituting the TL074CDT is choosing an amplifier with a different input technology (like Bipolar) which can drastically increase input bias current.
