Substitute Part Grouping Explanation

Substitution logic for the TL072IDRE4 is based on the following critical parameters: amplifier type (J-FET), number of circuits (2), package type (8-SOIC surface mount), and electrical performance specifications. Substitute parts are grouped into two categories based on amplifier type classification:

Category 1: J-FET Amplifiers (Direct Substitutes) Parts maintaining J-FET amplifier type with 2 circuits in 8-SOIC package. These include TL072IDR, TL072BIDT, TL072BIYDT, TL072CDT, TL072IDT, and TL082ACDT. These substitutes preserve the core J-FET input characteristics and are suitable for applications requiring low input bias current and high input impedance.

Category 2: Alternative Amplifier Types (Functional Substitutes) Parts with different amplifier types (Audio or General Purpose) but compatible package and circuit configuration. These include LM833DT (Audio amplifier) and MC33172D/MC33172DT (General Purpose amplifiers). These substitutes are applicable only when application requirements permit deviation from J-FET input characteristics.

Substitution eligibility requires: matching 8-SOIC package configuration, dual circuit count, surface mount mounting type, and operating temperature range compatibility with application requirements.

All automotive-qualified substitutes maintain ROHS3 compliance.

Q: What are the supply voltage compatibility considerations?

A: TL072IDRE4 operates across 10V to 30V supply range. TL072IDR maintains identical 10V to 30V range. TL072BIDT, TL072BIYDT, TL072CDT, TL072IDT, and TL082ACDT extend maximum supply to 36V with minimum reduced to 6V. LM833DT operates 5V to 30V. MC33172D and MC33172DT operate 4V to 44V. Verify application supply voltage requirements against substitute specifications before selection.

Q: How do input bias current specifications affect substitution?

A: TL072IDRE4 specifies 65 pA input bias current. TL072IDR maintains 65 pA. TL072BIDT, TL072BIYDT, TL072CDT, TL072IDT, and TL082ACDT reduce to 20 pA. LM833DT increases to 300 nA. MC33172D and MC33172DT specify 20 nA. Lower input bias current reduces input offset current effects in high-impedance circuits. Higher input bias current may require input bias current compensation in sensitive applications. Verify application input impedance and offset current requirements.
