OP27EPZ Equivalent & Substitute Parts

Part Overview

The OP27EPZ is a general-purpose operational amplifier manufactured by Analog Devices Inc., housed in an 8-PDIP through-hole package. This single-circuit linear amplifier is designed for applications requiring moderate bandwidth and low input offset voltage characteristics. The part is currently in active production status with 2,200 units available in inventory.

Substitute parts become necessary when the primary component is unavailable, when extended operating temperature ranges are required, or when specific performance characteristics must be optimized for particular circuit applications. The following equivalent parts maintain functional compatibility within the 8-DIP package format while offering variations in electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the OP27EPZ is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-DIP (0.300", 7.62mm) through-hole package format to ensure direct board-level replacement without layout modifications.

Supply Voltage Range: The OP27EPZ operates across 8 V to 36 V. Substitute parts must support this minimum and maximum supply voltage specification to function in existing power distribution architectures.

Amplifier Classification: All candidates are general-purpose operational amplifiers with single-circuit configurations, maintaining functional equivalence in circuit topology.

Compliance Standards: All parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity, ensuring compatibility with modern manufacturing and storage requirements.

Performance Variation Tolerance: Substitute parts may exhibit different slew rates, gain-bandwidth products, input bias currents, and input offset voltages. Selection depends on whether the application circuit can tolerate these parameter variations while maintaining system performance specifications.

Parameter Comparison

Engineering Selection Recommendations

OP27EPZ (Primary Part): This part is the baseline specification. All substitute selections should be evaluated against this reference. The OP27EPZ maintains active production status with the highest inventory level (2,200 units), ensuring availability for standard applications within the 0°C to 70°C operating temperature range.

LT1007IN8#PBF (Extended Temperature Substitute): This part is functionally equivalent to the OP27EPZ with identical supply voltage range (8 V to 36 V), slew rate (2.5 V/µs), and gain-bandwidth product (8 MHz). The primary distinction is the extended operating temperature range (-40°C to 85°C), which accommodates applications requiring operation beyond the standard 0°C to 70°C specification. Input bias current is slightly elevated at 15 nA versus 10 nA, and input offset voltage is 20 µV versus 10 µV. This part is suitable for temperature-critical applications where the OP27EPZ cannot be used.

OP07CN8#PBF and OP07EN8#PBF (Low-Noise, Low-Bandwidth Substitutes): Both OP07 variants feature significantly reduced slew rate (0.25 V/µs) and gain-bandwidth product (600 kHz) compared to the OP27EPZ (2.8 V/µs and 8 MHz respectively). The OP07CN8#PBF exhibits input bias current of 1.8 nA and input offset voltage of 60 µV. The OP07EN8#PBF provides superior input characteristics with 1.2 nA bias current and 30 µV offset voltage. Both OP07 parts support lower minimum supply voltage (6 V versus 8 V). These substitutes are appropriate only for applications where reduced bandwidth and slower signal processing are acceptable, such as precision measurement circuits or low-frequency signal conditioning.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and active production status, ensuring regulatory and supply chain compatibility with the OP27EPZ.

Frequently Asked Questions (FAQ)

Q: Can the LT1007IN8#PBF directly replace the OP27EPZ in all applications?

A: The LT1007IN8#PBF is a direct pin-compatible replacement in terms of package format (8-DIP) and supply voltage range (8 V to 36 V). However, the extended operating temperature range (-40°C to 85°C) and slightly different electrical characteristics (slew rate 2.5 V/µs versus 2.8 V/µs, input bias current 15 nA versus 10 nA) must be evaluated against circuit requirements. For applications operating within 0°C to 70°C, the OP27EPZ remains the primary specification.

Q: What is the key difference between the OP07 variants and the OP27EPZ?

A: The OP07CN8#PBF and OP07EN8#PBF are fundamentally different in bandwidth and slew rate performance. The OP27EPZ provides 8 MHz gain-bandwidth product and 2.8 V/µs slew rate, while both OP07 parts deliver only 600 kHz bandwidth and 0.25 V/µs slew rate. The OP07 variants are optimized for precision, low-noise applications and cannot substitute for the OP27EPZ in high-speed or wideband circuits.

Q: Are all substitute parts available in the same packaging?

A: Yes. The OP27EPZ, LT1007IN8#PBF, OP07CN8#PBF, and OP07EN8#PBF are all housed in 8-DIP (0.300", 7.62mm) through-hole packages with identical pin configurations, enabling direct board-level substitution without layout modifications.

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

A: The OP07EN8#PBF provides the lowest input offset voltage at 30 µV, compared to 10 µV for the OP27EPZ, 20 µV for the LT1007IN8#PBF, and 60 µV for the OP07CN8#PBF. However, the OP07EN8#PBF operates at significantly reduced bandwidth (600 kHz), limiting its use to low-frequency precision applications.

Q: What is the minimum supply voltage requirement for each part?

A: The OP27EPZ and LT1007IN8#PBF require a minimum supply voltage of 8 V. The OP07CN8#PBF and OP07EN8#PBF support lower minimum supply voltage of 6 V. All parts support maximum supply voltage of 36 V.

Q: Are all parts RoHS compliant?

A: Yes. The OP27EPZ, LT1007IN8#PBF, OP07CN8#PBF, and OP07EN8#PBF are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting current environmental and manufacturing standards.

Q: Which substitute part is best for applications requiring extended temperature operation?

A: The LT1007IN8#PBF is the only substitute offering extended operating temperature range (-40°C to 85°C) compared to the standard 0°C to 70°C specification of the OP27EPZ. This part is required for applications operating outside the standard temperature window.
