Procurement Notes
This component is officially listed as obsolete and no longer manufactured by onsemi. Procurement should focus on verified direct substitutes such as the UA741CP from Texas Instruments. Verify that replacement parts match the original pinout and electrical specifications to ensure compatibility in existing designs.
Selection Notes
Select this component only for legacy system maintenance or specific historical design requirements. Due to its obsolete status, new designs should utilize modern equivalents. Ensure the selected substitute maintains the same 8-DIP footprint and meets the required 0.5 V/µs slew rate and 80 nA input bias current specifications for functional parity.
Part Context
The KA741 series represents a classic line of general-purpose operational amplifiers widely used in analog electronics. The KA741DTF specifically denotes the surface-mount or specific packaging variant distributed by Fairchild Semiconductor. This series is known for its robust performance in standard linear applications, forming a foundational component in many established electronic circuit architectures.
Replacement Considerations
Direct substitute: UA741CP (Texas Instruments). Similar alternative: LM741CN/NOPB (Texas Instruments). Verify pin compatibility and electrical equivalence before integration.
