Engineering Selection Recommendations

Direct Equivalent: AMP02EPZ is the direct equivalent to AMP02EP, offering identical electrical specifications with active product status. This part is ROHS3 compliant and REACH unaffected, making it the primary replacement for obsolete AMP02EP applications. The only difference is packaging format (Tube versus unspecified for AMP02EP).

Active Alternatives with Full Compatibility: INA111BP and INA111AP (Texas Instruments) provide superior performance characteristics including higher slew rate (17V/µs versus 6V/µs) and greater bandwidth (2 MHz versus 1.2 MHz). Both maintain the 8-DIP package format and -40°C to 85°C operating range. These parts are ROHS3 compliant and REACH unaffected. However, minimum supply voltage requirement is 12V, which exceeds the AMP02EP minimum of 9V. Applications operating below 12V supply voltage cannot use these alternatives.

Partial Compatibility Alternatives: INA114AP, INA114BP, INA118P, INA118PB, INA121P, and INA121PA offer instrumentation amplification in 8-DIP packages with active product status and full compliance certifications. These parts present trade-offs in performance parameters. INA114 series devices have reduced slew rate (0.6V/µs) and bandwidth (1 MHz), limiting high-frequency applications. INA118 series devices have the lowest supply current (350µA) but reduced output current capability (12 mA) and bandwidth (800 kHz). INA121 series devices have the lowest bandwidth (600 kHz) and reduced output current (14 mA).

Minimum Supply Voltage Consideration: INA114 series, INA121 series, and INA128P operate with minimum supply voltage of 4.5V, providing greater flexibility for low-voltage applications compared to AMP02EP (9V minimum). INA118 series operates at 2.7V minimum, offering maximum low-voltage flexibility.

Last Time Buy Status: INA128P carries Last Time Buy status, indicating limited future availability. While electrically compatible with performance characteristics exceeding AMP02EP specifications, long-term supply cannot be guaranteed.

Frequently Asked Questions (FAQ)

Q: Can AMP02EPZ be used as a direct replacement for AMP02EP? A: Yes. AMP02EPZ is electrically identical to AMP02EP with all specifications matching exactly. The difference is packaging format (Tube). Both are 8-DIP through-hole packages with identical pin configurations. AMP02EPZ has active product status, making it suitable for new designs and production.

Q: What is the primary limitation when substituting INA111AP or INA111BP for AMP02EP? A: The minimum supply voltage requirement. INA111 series requires minimum 12V supply, while AMP02EP operates from 9V minimum. Applications using 9V to 11.9V supply voltage cannot use INA111 alternatives. For applications with 12V or higher supply voltage, INA111 series offers superior slew rate and bandwidth performance.

Q: Are all substitute parts available in 8-DIP through-hole packages? A: Yes. All listed substitute parts are housed in 8-DIP (0.300", 7.62mm) packages with through-hole mounting, ensuring mechanical compatibility with AMP02EP footprints.

Q: Which substitute part has the lowest power consumption? A: INA118P and INA118PB have the lowest supply current at 350µA, compared to AMP02EP at 5mA. However, these parts have reduced output current capability (12 mA versus 32 mA) and lower bandwidth (800 kHz versus 1.2 MHz).

Q: Are all substitute parts RoHS compliant? A: All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between INA114AP and INA114BP? A: Both parts are electrically identical except for input offset voltage. INA114BP specifies 10µV maximum offset voltage, while INA114AP specifies 25µV. INA114BP provides tighter offset voltage tolerance for precision applications. Both have identical slew rate (0.6V/µs), bandwidth (1 MHz), and all other electrical parameters.

Q: Can INA128P be used for new designs? A: INA128P carries Last Time Buy status, indicating the manufacturer has announced end-of-life. While currently available, long-term supply cannot be guaranteed. For new designs requiring long-term production support, AMP02EPZ or INA111 series are recommended.

Q: Which substitute part most closely matches AMP02EP performance? A: AMP02EPZ is the exact electrical match. For alternative manufacturers, INA128P provides the closest performance match with 4V/µs slew rate (versus 6V/µs) and 1.3 MHz bandwidth (versus 1.2 MHz), while maintaining 2nA input bias current and 32mA output current capability.
