OP07EP Equivalent & Substitute Parts Reference

Part Overview

The OP07EP is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-PDIP through-hole package. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production continuity. The OP07EP operates across a wide supply voltage range of 6V to 36V and is suitable for applications requiring low input offset voltage and low input bias current characteristics.

Substitute Part Grouping Explanation

Substitution of the OP07EP is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

Amplifier Type: General Purpose
Number of Circuits: 1
Package / Case: 8-DIP (0.300", 7.62mm)
Mounting Type: Through Hole
Gain Bandwidth Product: 600 kHz
Voltage - Supply Span: 6V to 36V minimum

Secondary Compatibility Parameters:

Slew Rate: 0.3 V/µs (baseline specification)
Current - Input Bias: 1.2 nA (baseline specification)
Voltage - Input Offset: 30 µV (baseline specification)

Substitute parts are grouped into two categories:

Category 1: Direct Equivalents (Identical Electrical Specifications) Parts that maintain all baseline electrical parameters while offering improved product status or compliance certifications.

Category 2: Functional Equivalents (Relaxed Electrical Specifications) Parts that maintain core functionality and package compatibility but with modified electrical characteristics within acceptable engineering tolerances for general-purpose amplifier applications.

Engineering Selection Recommendations

For RoHS3 Compliance Requirements:

OP07EPZ is the primary substitute when RoHS3 compliance is mandatory. This part maintains identical electrical specifications to the OP07EP (1.2 nA input bias current, 30 µV input offset voltage, 0.3 V/µs slew rate) while achieving ROHS3 Compliant status. The part is currently in active production with 1404 units in stock.

For Extended Temperature Range Applications:

OP07CPZ extends the operating temperature range to -40°C to 85°C while maintaining RoHS3 compliance. Input bias current increases to 1.8 nA and input offset voltage increases to 60 µV. This part is suitable for applications requiring wider temperature operation within the specified electrical tolerance band. 17300 units are in stock.

For Highest Temperature Operation:

OP07DNZ supports the widest operating temperature range (-40°C to 125°C) with RoHS3 compliance. This part exhibits lower input bias current (200 pA) and modified slew rate (0.2 V/µs). Minimum supply voltage increases to 8V. This part is appropriate for extreme temperature environments where the modified electrical characteristics are acceptable.

For Broad Availability and Active Production:

OP07CP (Texas Instruments) offers the highest inventory availability (21974 units) with active product status and RoHS3 compliance. Electrical specifications show 1.8 nA input bias current and 60 µV input offset voltage. Operating temperature range is 0°C to 70°C, matching the OP07EP baseline.

For Superior Input Offset Voltage Performance:

OPA177GP provides the lowest input offset voltage (20 µV) among active substitutes, with extended temperature range (-40°C to 85°C) and RoHS3 compliance. Input bias current is 500 pA. This part is designated Last Time Buy status with 3933 units available.

Obsolete Parts to Avoid:

OP07DP remains obsolete and RoHS non-compliant. While electrically similar to OP07EP, this part offers no compliance advantage and should not be selected for new designs.

Frequently Asked Questions (FAQ)

Q: Can OP07EPZ be used as a direct replacement for OP07EP?

A: Yes. OP07EPZ maintains identical electrical specifications (1.2 nA input bias current, 30 µV input offset voltage, 0.3 V/µs slew rate, 600 kHz gain bandwidth product) and identical package configuration (8-DIP through-hole). The primary difference is product status (Active vs. Obsolete) and RoHS3 compliance. Both parts operate across 6V to 36V supply range and 0°C to 70°C temperature range.

Q: What is the difference between OP07CP and OP07CPZ?

A: Both parts are manufactured by Analog Devices Inc. and maintain identical electrical specifications (1.8 nA input bias current, 60 µV input offset voltage). OP07CP is manufactured by Texas Instruments. OP07CPZ extends the operating temperature range to -40°C to 85°C, compared to OP07CP at 0°C to 70°C. Both are RoHS3 compliant and housed in 8-DIP packages.

Q: Why does OP07DNZ have a higher minimum supply voltage (8V vs. 6V)?

A: OP07DNZ is specified with an 8V minimum supply voltage as part of its design parameters. Applications requiring 6V minimum supply operation should select OP07EPZ, OP07CP, OP07CPZ, or OPA177GP instead.

Q: Is OP07DNZ suitable for applications requiring 0.3 V/µs slew rate?

A: No. OP07DNZ is specified at 0.2 V/µs slew rate, which is lower than the OP07EP baseline of 0.3 V/µs. Applications with slew rate requirements of 0.3 V/µs or higher should select OP07EPZ, OP07CP, OP07CPZ, OP07DP, or OPA177GP.

Q: Can I use OPA177GP in place of OP07EP?

A: OPA177GP is functionally compatible in 8-DIP through-hole package configuration and maintains 600 kHz gain bandwidth product and 0.3 V/µs slew rate. However, OPA177GP exhibits superior input offset voltage (20 µV vs. 30 µV) and lower input bias current (500 pA vs. 1.2 nA). OPA177GP is designated Last Time Buy status. Verify application tolerance to lower input bias current before selection.

Q: Which substitute offers the best long-term availability?

A: OP07CP (Texas Instruments) offers the highest inventory (21974 units) with active product status. OP07CPZ (Analog Devices Inc.) provides 17300 units in stock with active status and extended temperature range. Both parts are RoHS3 compliant and suitable for new designs.

Q: Are all substitute parts RoHS3 compliant?

A: No. OP07DP remains RoHS non-compliant. All other listed substitutes (OP07EPZ, OP07CP, OP07CPZ, OP07DNZ, OPA177GP) are ROHS3 Compliant. For applications requiring RoHS compliance, avoid OP07DP.

Q: What is the significance of "Last Time Buy" status for OPA177GP?

A: Last Time Buy status indicates that OPA177GP will be discontinued after a specified date. While currently available (3933 units in stock), this part should not be selected for new long-term production designs. OP07EPZ, OP07CP, or OP07CPZ are preferred for ongoing production requirements.
