LT1007CJ8 Equivalent & Substitute Parts

Part Overview

The LT1007CJ8 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, indicating that it is no longer in active production. The LT1007CJ8 remains suitable for applications requiring low input bias current and low input offset voltage characteristics within the specified operating temperature range of 0°C to 70°C.

Due to its obsolete status, equivalent and substitute parts are necessary for new designs, production continuity, and long-term component availability. Active alternatives with compatible electrical and mechanical specifications are available from the same manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1007CJ8 is determined by the following critical parameters:

Electrical Compatibility:

• Gain Bandwidth Product: 8 MHz (must match)
• Voltage Supply Span: 8 V to 36 V (must match)
• Amplifier Type: General Purpose (must match)
• Number of Circuits: 1 (must match)

Mechanical Compatibility:

• Mounting Type: Through Hole (must match)
• Package / Case: 8-CDIP or 8-DIP (0.300", 7.62mm) (must be compatible)
• Moisture Sensitivity Level: 1 (Unlimited) (must match)

Performance Parameters (Secondary):

• Slew Rate: 2.5 V/µs or higher (acceptable if equal or greater)
• Current - Input Bias: 15 nA or lower (acceptable if equal or lower)
• Voltage - Input Offset: 20 µV or lower (acceptable if equal or lower)

The substitute parts OP27EZ and OP27GZ meet the primary electrical and mechanical compatibility criteria. Both are active products from Analog Devices Inc. with identical supply voltage ranges and gain bandwidth products.

Parameter Comparison

Engineering Selection Recommendations

OP27EZ Selection Criteria:

The OP27EZ is an active product with ROHS3 compliance and REACH unaffected status. It provides identical electrical specifications to the LT1007CJ8 with the following advantages: improved slew rate (2.8 V/µs versus 2.5 V/µs), lower input bias current (10 nA versus 15 nA), and lower input offset voltage (10 µV versus 20 µV). The OP27EZ operates across an extended temperature range (-25°C to 85°C) compared to the LT1007CJ8 (0°C to 70°C). Package compatibility is direct: both use 8-CDIP (0.300", 7.62mm) through-hole configuration. The OP27EZ is suitable for applications requiring enhanced performance characteristics within the same form factor.

OP27GZ Selection Criteria:

The OP27GZ is an active product with ROHS3 compliance and REACH unaffected status. It maintains identical electrical specifications to the LT1007CJ8 with improved slew rate (2.8 V/µs versus 2.5 V/µs) and an extended operating temperature range (-40°C to 85°C). The OP27GZ uses an 8-DIP (0.300", 7.62mm) package, which is mechanically compatible with the 8-CDIP footprint for through-hole mounting applications. Input offset voltage is 30 µV, which exceeds the LT1007CJ8 specification of 20 µV. The OP27GZ is suitable for applications requiring extended low-temperature operation.

Compliance and Availability:

Both substitute parts are manufactured by Analog Devices Inc. and carry active product status with current inventory availability. Both parts comply with ROHS3 and REACH requirements, supporting modern design and manufacturing standards. The LT1007CJ8, classified as obsolete, lacks these compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the OP27EZ directly replace the LT1007CJ8 in existing designs?

A: The OP27EZ is electrically and mechanically compatible with the LT1007CJ8. Both devices use identical 8-CDIP through-hole packages and share the same supply voltage range (8 V to 36 V) and gain bandwidth product (8 MHz). The OP27EZ provides improved performance characteristics (lower input bias current, lower input offset voltage, and higher slew rate) while maintaining backward compatibility. No circuit modifications are required for direct substitution.

Q: What is the difference between the OP27EZ and OP27GZ packages?

A: The OP27EZ uses an 8-CDIP (0.300", 7.62mm) package, identical to the LT1007CJ8. The OP27GZ uses an 8-DIP (0.300", 7.62mm) package. Both packages are through-hole mounted with 0.300-inch (7.62mm) body width and are mechanically compatible for PCB footprints designed for 8-pin DIP configurations. The primary difference is the package designation; both are suitable for through-hole assembly.

Q: Which substitute part should be selected for extended temperature operation?

A: The OP27GZ operates across -40°C to 85°C, providing the widest temperature range. The OP27EZ operates across -25°C to 85°C. The LT1007CJ8 operates across 0°C to 70°C. Selection depends on the specific application temperature requirements. For applications requiring operation below 0°C, the OP27EZ or OP27GZ are required.

Q: Are the substitute parts RoHS and REACH compliant?

A: Both the OP27EZ and OP27GZ are ROHS3 compliant and REACH unaffected. The LT1007CJ8 does not carry these compliance certifications. For applications requiring regulatory compliance with modern environmental standards, the substitute parts are appropriate selections.

Q: What are the input offset voltage differences between the three parts?

A: The LT1007CJ8 specifies 20 µV input offset voltage. The OP27EZ specifies 10 µV, providing superior performance. The OP27GZ specifies 30 µV, which exceeds the LT1007CJ8 specification. For applications with strict input offset voltage requirements, the OP27EZ is the preferred substitute.

Q: Can the OP27EZ and OP27GZ be used interchangeably?

A: The OP27EZ and OP27GZ share identical electrical specifications (gain bandwidth product, supply voltage range, slew rate) and are both active products from Analog Devices Inc. The primary differences are package type (8-CDIP versus 8-DIP), operating temperature range, and input offset voltage specification. Selection depends on specific PCB footprint requirements and application temperature range. They are not interchangeable without considering these factors.

Q: What is the inventory status of these substitute parts?

A: The LT1007CJ8 has 924 pieces in stock but is classified as obsolete. The OP27EZ has 1765 pieces in stock and is active. The OP27GZ has 2391 pieces in stock and is active. For long-term component availability and production continuity, the active substitute parts are recommended.
