OP97EN8#PBF Equivalent & Substitute Parts

Part Overview

The OP97EN8#PBF is a general-purpose operational amplifier manufactured by Analog Devices Inc., housed in an 8-DIP through-hole package. This linear amplifier integrated circuit contains a single amplification circuit and is designed for applications requiring low input bias current and low input offset voltage characteristics. The part is currently in active production status with 674 units available in inventory.

Substitute parts become necessary when the primary part number experiences supply constraints, extended lead times, or when design flexibility permits selection from equivalent alternatives that meet identical electrical and mechanical specifications. The OP97EN8#PBF has documented substitute options within the Analog Devices OP97 series and cross-manufacturer alternatives that maintain functional compatibility.

Engineering Selection Recommendations

Direct Equivalent - OP97EPZ: The OP97EPZ is a direct electrical and mechanical equivalent to the OP97EN8#PBF. All electrical parameters match exactly, including slew rate, bandwidth, input bias current, input offset voltage, supply current, and supply voltage range. Both parts are manufactured by Analog Devices Inc., share identical package specifications (8-DIP through-hole), and maintain active production status. The OP97EPZ has higher inventory availability (3500 units) compared to the primary part. This substitute is suitable for direct replacement without circuit redesign.

Similar Alternative - OP97FPZ: The OP97FPZ is manufactured by Analog Devices Inc. and shares the same base product number (OP97) with identical mechanical packaging and mounting characteristics. Electrical parameters are equivalent except for Voltage - Input Offset, which is specified at 30 µV compared to 10 µV for the primary part. This represents a 3x increase in input offset voltage specification. The OP97FPZ maintains active production status with high inventory availability (4453 units). Selection of this part requires verification that the increased input offset voltage specification is acceptable for the intended application.

Cross-Manufacturer Alternative - OPA177FP: The OPA177FP is manufactured by Texas Instruments and provides an 8-DIP through-hole package equivalent. This part exhibits multiple electrical parameter deviations from the OP97EN8#PBF: slew rate is 0.3 V/µs (50% higher), -3dB bandwidth is 600 kHz (33% lower), input bias current is 500 pA (16.7x higher), and supply current is 1.3 mA (3.4x higher). Additionally, the supply voltage range is restricted to 6 V to 36 V compared to 4 V to 40 V. The OPA177FP carries a Last Time Buy product status, indicating discontinued production. This part is not recommended for new designs and should only be considered for legacy system maintenance where electrical parameter variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can OP97EPZ be used as a direct replacement for OP97EN8#PBF?

A: Yes. The OP97EPZ is a direct equivalent with identical electrical specifications, package configuration, and compliance certifications. No circuit modifications are required.

Q: What is the difference between OP97FPZ and OP97EN8#PBF?

A: The OP97FPZ has an input offset voltage specification of 30 µV compared to 10 µV for the OP97EN8#PBF. All other electrical and mechanical parameters are identical. The higher input offset voltage may affect circuit accuracy in precision applications.

Q: Is OPA177FP a suitable substitute for OP97EN8#PBF?

A: The OPA177FP is not recommended as a direct substitute. It exhibits significant electrical parameter differences including higher slew rate (0.3 V/µs vs. 0.2 V/µs), lower bandwidth (600 kHz vs. 900 kHz), higher input bias current (500 pA vs. 30 pA), and higher supply current (1.3 mA vs. 380 µA). Additionally, the OPA177FP is in Last Time Buy status. Use only if circuit design accommodates these parameter variations.

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

A: Yes. All listed substitute parts (OP97EPZ, OP97FPZ, and OPA177FP) are housed in 8-DIP (0.300", 7.62mm) through-hole packages with identical pin configurations and mechanical dimensions.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. The OP97EPZ, OP97FPZ, and OPA177FP are all ROHS3 compliant. All parts maintain REACH Unaffected status.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across the -40°C to 85°C temperature range, matching the primary part specification.

Q: Which substitute part has the best inventory availability?

A: The OP97FPZ has the highest inventory with 4453 units in stock, followed by OP97EPZ with 3500 units. The primary part OP97EN8#PBF has 674 units available.

Q: Can OP97FPZ be used in precision measurement circuits?

A: The OP97FPZ has a 30 µV input offset voltage specification compared to 10 µV for the primary part. Applications requiring input offset voltage below 30 µV should not use the OP97FPZ without circuit compensation or recalibration.

Q: Why is OPA177FP marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the OPA177FP. Existing inventory is available for purchase, but no future production is planned. This part should not be selected for new designs.
