OP07AJ8 Equivalent & Substitute Parts

Part Overview

The OP07AJ8 is a general-purpose operational amplifier manufactured by Analog Devices Inc., housed in an 8-CERDIP through-hole package. This device is classified as obsolete, though 903 pieces remain available in new original stock. The OP07AJ8 features a slew rate of 0.25V/µs, gain bandwidth product of 600 kHz, and operates across a supply voltage range of 6V to 36V with an operating temperature range of -55°C to 125°C.

Due to its obsolete status, identifying equivalent and substitute parts is necessary for ongoing design support, production continuity, and long-term component availability. Substitute parts must maintain functional compatibility while meeting the electrical and mechanical requirements of the original design.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OP07AJ8 are selected based on strict compatibility criteria derived from the provided electrical and mechanical parameters. The primary substitution logic is as follows:

Critical Compatibility Parameters:

• Amplifier Type: General Purpose (all substitutes match)
• Number of Circuits: 1 (all substitutes match)
• Mounting Type: Through Hole (all substitutes match)
• Voltage - Supply Span: Minimum 6V, Maximum 36V (all substitutes meet or exceed)
• Voltage - Input Offset: 10 µV (all substitutes match)
• Moisture Sensitivity Level: 1 (Unlimited) (all substitutes match)

Substitution Categories:

Category 1: Direct Package Equivalents (8-CERDIP) OP27AZ/883C, OP27EZ, OP77EZ, and OP27AZ maintain the identical 8-CERDIP package form factor as the OP07AJ8. These parts are pin-compatible and require no physical modifications to existing printed circuit boards.

Category 2: Functional Equivalents with Package Variation (8-DIP) OP37EZ and OP27GZ utilize an 8-DIP package instead of 8-CERDIP. While electrically compatible, these parts require PCB layout modifications due to different package geometry.

Performance Considerations: Substitute parts exhibit performance variations in slew rate and gain bandwidth product. The OP07AJ8 operates at 0.25V/µs slew rate and 600 kHz bandwidth. Substitutes range from 0.3V/µs to 17V/µs slew rate and 600 kHz to 63 MHz bandwidth. Selection depends on whether the application requires equivalent or enhanced performance characteristics.

Product Status: All substitute parts listed carry Active product status, ensuring ongoing availability and manufacturer support, in contrast to the obsolete OP07AJ8.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (No PCB Modification Required):

OP27AZ/883C is the preferred substitute when military-grade qualification is required. This part carries MIL-STD-883 qualification and maintains the full operating temperature range of -55°C to 125°C, matching the OP07AJ8. It is housed in the 8-CERDIP package and is RoHS3 compliant.

OP27AZ provides an active-status alternative with identical operating temperature range (-55°C to 125°C) and 8-CERDIP package compatibility. This part is RoHS3 compliant and REACH unaffected.

OP77EZ is suitable for applications where low input bias current (1.2 nA) is advantageous and operating temperature range can be reduced to -25°C to 85°C. This part maintains the 600 kHz gain bandwidth product of the OP07AJ8 and is housed in the 8-CERDIP package.

OP27EZ offers active status with 8-CERDIP package compatibility but operates within a reduced temperature range of -25°C to 85°C. This part is suitable for commercial and industrial applications not requiring the full military temperature range.

For Applications Permitting Package Variation (PCB Modification Required):

OP37EZ provides significantly enhanced performance with 17V/µs slew rate and 63 MHz gain bandwidth product. This part operates within 0°C to 70°C temperature range and uses an 8-DIP package requiring PCB layout changes.

OP27GZ offers 8-DIP package form factor with 2.8V/µs slew rate and 8 MHz bandwidth. Operating temperature range is -40°C to 85°C. Input offset voltage is 30 µV, which differs from the OP07AJ8 specification of 10 µV.

Compliance and Certification:

All substitute parts carry RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current environmental standards. OP27AZ/883C additionally carries MIL-STD-883 qualification for military applications.

Frequently Asked Questions (FAQ)

Q: Can OP27AZ/883C be used as a direct replacement for OP07AJ8 without circuit modifications?

A: Yes. OP27AZ/883C is pin-compatible with OP07AJ8, both utilizing the 8-CERDIP package. No circuit modifications are required. However, the electrical performance differs: OP27AZ/883C provides 2.8V/µs slew rate and 8 MHz bandwidth compared to OP07AJ8's 0.25V/µs and 600 kHz. Verify that the application circuit tolerates these performance enhancements.

Q: What is the primary difference between OP27AZ and OP27AZ/883C?

A: OP27AZ/883C carries MIL-STD-883 military qualification, while OP27AZ does not. Both parts share identical electrical specifications and 8-CERDIP package. OP27AZ/883C is specified for military applications requiring formal qualification documentation.

Q: Why do OP37EZ and OP27GZ require PCB modifications?

A: OP37EZ and OP27GZ use 8-DIP package geometry, while OP07AJ8 uses 8-CERDIP. Although both packages are 0.300" (7.62mm) wide, the internal lead configurations differ. PCB footprints must be redesigned to accommodate the different package pinout layout.

Q: Is OP77EZ suitable for high-speed applications?

A: No. OP77EZ maintains the 600 kHz gain bandwidth product of OP07AJ8, making it suitable for low-frequency applications. For high-speed requirements, OP37EZ (63 MHz) or OP27AZ/883C (8 MHz) are more appropriate.

Q: What is the impact of reduced operating temperature range on substitute selection?

A: OP27EZ and OP77EZ operate within -25°C to 85°C, while OP07AJ8 operates within -55°C to 125°C. If the application requires the full -55°C to 125°C range, select OP27AZ/883C or OP27AZ. For applications operating within commercial or industrial temperature ranges, OP27EZ and OP77EZ are acceptable.

Q: Does OP27GZ meet the input offset voltage specification of OP07AJ8?

A: No. OP27GZ specifies 30 µV input offset voltage, while OP07AJ8 specifies 10 µV. Applications sensitive to input offset voltage drift should select alternatives with 10 µV specification: OP27AZ/883C, OP27EZ, OP37EZ, OP77EZ, or OP27AZ.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance status. OP07AJ8 compliance status is not specified in the provided data.

Q: Which substitute part offers the lowest input bias current?

A: OP77EZ provides the lowest input bias current at 1.2 nA. OP07AJ8 specifies 700 pA input bias current. All other substitutes specify 10 nA or 15 nA input bias current.

Q: Can OP37EZ be used in applications designed for OP07AJ8 without performance concerns?

A: OP37EZ provides enhanced performance (17V/µs slew rate, 63 MHz bandwidth) compared to OP07AJ8 (0.25V/µs, 600 kHz). While pin-compatible in principle, OP37EZ uses 8-DIP package requiring PCB modification. Additionally, OP37EZ operates within 0°C to 70°C, a narrower range than OP07AJ8. Verify application requirements before selection.
