OP27EN8#PBF Equivalent & Substitute Parts

Part Overview

The OP27EN8#PBF is a general-purpose operational amplifier manufactured by Analog Devices Inc., housed in an 8-DIP through-hole package. This device is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory. The OP27EN8#PBF delivers precision performance with a slew rate of 2.8V/µs, gain bandwidth product of 8 MHz, and low input bias current of 10 nA, making it suitable for applications requiring stable amplification across a wide supply voltage range of 8V to 36V and operating temperatures from -25°C to 85°C.

Identifying equivalent and substitute parts is necessary due to the Last Time Buy status of the OP27EN8#PBF. Alternative components ensure design continuity, supply chain reliability, and long-term product availability for new designs or production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP27EN8#PBF is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Slew Rate: 2.8V/µs (minimum acceptable performance)
• Gain Bandwidth Product: 8 MHz (minimum acceptable performance)
• Current - Input Bias: 10 nA (maximum acceptable value)
• Voltage - Input Offset: 10 µV (maximum acceptable value)
• Voltage - Supply Span: 8V to 36V (operating range)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: 8-DIP (0.300", 7.62mm)
• Supplier Device Package: 8-PDIP

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are classified into two categories:

MFR Recommended Substitute (Direct Equivalent): OP27EPZ maintains identical electrical specifications and package configuration, with the primary difference being product status (Active vs. Last Time Buy) and operating temperature range.

Similar Manufacturer Part (Functional Alternative): LM741CN/NOPB provides general-purpose amplification in the same 8-DIP package but with reduced electrical performance specifications. This part is suitable only for applications where lower slew rate, reduced gain bandwidth product, and higher input bias current are acceptable.

Parameter Comparison

Engineering Selection Recommendations

OP27EPZ (MFR Recommended Substitute): OP27EPZ is the primary substitute for OP27EN8#PBF. Both parts are manufactured by Analog Devices Inc. and maintain identical electrical specifications including slew rate, gain bandwidth product, input bias current, and input offset voltage. Both are ROHS3 compliant with MSL 1 rating. The OP27EPZ carries Active product status, ensuring continued availability and supply chain stability. The operating temperature range of OP27EPZ (0°C ~ 70°C) is narrower than the OP27EN8#PBF (-25°C ~ 85°C); therefore, OP27EPZ is suitable for applications operating within the 0°C to 70°C range. For applications requiring extended temperature operation below 0°C or above 70°C, the OP27EN8#PBF remains the only qualified option.

LM741CN/NOPB (Functional Alternative): LM741CN/NOPB is a functional alternative manufactured by Texas Instruments. This part shares the same 8-DIP package and general-purpose amplifier classification. However, LM741CN/NOPB exhibits significantly reduced electrical performance: slew rate of 0.5V/µs (versus 2.8V/µs), gain bandwidth product of 1.5 MHz (versus 8 MHz), input bias current of 80 nA (versus 10 nA), and input offset voltage of 2 mV (versus 10 µV). LM741CN/NOPB is suitable only for applications where these reduced specifications are acceptable. The minimum supply voltage requirement is 10V (versus 8V for OP27EN8#PBF), which may restrict use in low-voltage applications. LM741CN/NOPB is ROHS3 compliant with MSL 1 rating and carries Active product status.

Frequently Asked Questions (FAQ)

Q: Can OP27EPZ be used as a direct replacement for OP27EN8#PBF in all applications?

A: OP27EPZ is electrically equivalent to OP27EN8#PBF and shares the same 8-DIP package. Direct substitution is valid for applications operating within the OP27EPZ temperature range of 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must retain the OP27EN8#PBF or identify an alternative part with extended temperature specifications.

Q: What are the key electrical differences between OP27EN8#PBF and LM741CN/NOPB?

A: The LM741CN/NOPB exhibits lower performance across multiple parameters: slew rate is 0.5V/µs compared to 2.8V/µs, gain bandwidth product is 1.5 MHz compared to 8 MHz, input bias current is 80 nA compared to 10 nA, and input offset voltage is 2 mV compared to 10 µV. Additionally, LM741CN/NOPB requires a minimum supply voltage of 10V, whereas OP27EN8#PBF operates from 8V. These differences make LM741CN/NOPB unsuitable for precision applications or those requiring high-speed performance.

Q: Are all three parts pin-compatible?

A: Yes. OP27EN8#PBF, OP27EPZ, and LM741CN/NOPB all use the 8-DIP (0.300", 7.62mm) package with identical pin configurations for through-hole mounting. Pin-level compatibility is confirmed; however, electrical performance differences must be evaluated for circuit-specific requirements.

Q: Why is OP27EN8#PBF classified as Last Time Buy?

A: Last Time Buy status indicates that Analog Devices Inc. has discontinued production of the OP27EN8#PBF. Existing inventory is limited to 2100 pieces. This classification necessitates identification of alternative parts for new designs or future production runs to ensure supply chain continuity.

Q: Are OP27EN8#PBF, OP27EPZ, and LM741CN/NOPB compliant with RoHS and REACH regulations?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. All three carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the primary reason to choose OP27EPZ over LM741CN/NOPB?

A: OP27EPZ maintains the electrical performance specifications of the original OP27EN8#PBF, including superior slew rate (2.8V/µs vs. 0.5V/µs), higher gain bandwidth product (8 MHz vs. 1.5 MHz), lower input bias current (10 nA vs. 80 nA), and lower input offset voltage (10 µV vs. 2 mV). OP27EPZ is the appropriate choice for applications requiring precision amplification and high-speed performance. LM741CN/NOPB is suitable only for legacy designs or applications with relaxed performance requirements.

Q: Can LM741CN/NOPB be used in applications originally designed for OP27EN8#PBF?

A: LM741CN/NOPB can be used only if the application circuit tolerates the reduced electrical specifications. Circuit redesign or performance degradation may result. For applications requiring the original performance characteristics, OP27EPZ is the appropriate substitute within its operating temperature range.
