AMP02FP Equivalent & Substitute Parts

Part Overview

The AMP02FP is an instrumentation amplifier manufactured by Analog Devices Inc., featuring a single circuit in an 8-PDIP package. This device operates across a supply voltage range of 9V to 36V with a slew rate of 6V/µs and -3dB bandwidth of 1.2 MHz. The AMP02FP is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. Alternative instrumentation amplifiers in the same package format and compatible electrical specifications are available from both Analog Devices and Texas Instruments.

Substitute Part Grouping Explanation

Substitution of the AMP02FP is determined by compatibility across the following critical parameters: package format (8-DIP), mounting type (Through Hole), operating temperature range (-40°C to 85°C), and electrical specifications including supply voltage range, slew rate, bandwidth, input bias current, input offset voltage, supply current, and output current capability.

The substitute parts are grouped into two categories:

Direct Equivalent: AMP02FPZ maintains identical electrical specifications and differs only in packaging format (Tube vs. unspecified for the main part) and product status (Active vs. Obsolete).

Compatible Alternatives: Texas Instruments instrumentation amplifiers (INA111AP, INA111BP, INA114AP, INA114BP, INA118P, INA118PB, INA121P, INA121PA, INA128P) operate in the same 8-DIP package and share the same operating temperature range. These alternatives vary in slew rate, bandwidth, input bias current, input offset voltage, supply current, and output current specifications, but remain functionally compatible within the 8-DIP form factor and support the -40°C to 85°C operating window.

Engineering Selection Recommendations

Direct Replacement: AMP02FPZ is the direct equivalent to AMP02FP with identical electrical specifications. This part is currently in Active product status and is ROHS3 Compliant, making it the preferred choice for direct substitution where supply voltage requirements are 9V minimum.

Alternative Selection Criteria:

For applications requiring lower minimum supply voltage (below 9V), INA114AP, INA114BP, INA121P, INA121PA, and INA128P support operation at 4.5V minimum. INA118P and INA118PB extend compatibility to 2.7V minimum supply voltage.

For applications requiring higher slew rate performance, INA111AP and INA111BP provide 17V/µs slew rate compared to the AMP02FP specification of 6V/µs.

For applications requiring lower supply current consumption, INA118P, INA118PB, INA121P, and INA121PA operate at 350µA to 450µA compared to the AMP02FP specification of 5mA.

All substitute parts listed are ROHS3 Compliant and REACH Unaffected, supporting compliance requirements equivalent to or exceeding the original AMP02FP specification.

Frequently Asked Questions (FAQ)

Q: Can AMP02FPZ be used as a direct replacement for AMP02FP?

A: Yes. AMP02FPZ maintains identical electrical specifications including slew rate (6V/µs), bandwidth (1.2 MHz), input bias current (4 nA), input offset voltage (40 µV), supply current (5 mA), output current (32 mA), and supply voltage range (9V to 36V). The only difference is packaging format (Tube) and product status (Active vs. Obsolete). Both use the 8-DIP package format.

Q: What is the minimum supply voltage requirement for substitute parts?

A: The AMP02FP requires a minimum supply voltage of 9V. Substitute parts vary: AMP02FPZ maintains this 9V minimum. INA114AP, INA114BP, INA121P, INA121PA, and INA128P operate at 4.5V minimum. INA118P and INA118PB operate at 2.7V minimum. INA111AP and INA111BP require 12V minimum. Verify your application's supply voltage compatibility before selection.

Q: Are all substitute parts available in the same 8-DIP package?

A: Yes. All substitute parts listed are packaged in 8-DIP (0.300", 7.62mm) format with Through Hole mounting type, maintaining mechanical compatibility with the AMP02FP footprint.

Q: Which substitute part has the lowest input offset voltage?

A: INA114BP and INA128P both specify 10 µV input offset voltage, compared to the AMP02FP specification of 40 µV. INA111BP also specifies 100 µV input offset voltage.

Q: What is the product status of available substitutes?

A: AMP02FPZ is Active. INA111AP, INA111BP, INA114AP, INA114BP, INA118P, INA118PB, INA121P, and INA121PA are Active. INA128P is Last Time Buy status. All alternatives provide active manufacturing support except INA128P, which has limited availability.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part has the lowest supply current consumption?

A: INA118P and INA118PB specify 350µA supply current, significantly lower than the AMP02FP specification of 5mA. INA121P and INA121PA specify 450µA. These options are suitable for battery-powered or low-power applications.
