MCP6023-I/P Equivalent & Substitute Parts

Part Overview

The MCP6023-I/P is a general-purpose operational amplifier manufactured by Microchip Technology, housed in an 8-PDIP through-hole package. This rail-to-rail amplifier operates across a 2.5V to 5.5V supply range with a 10 MHz gain-bandwidth product and 7V/µs slew rate. The device is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and functional compatibility are required due to inventory constraints, manufacturing discontinuation, or specific application requirements within the defined parameter envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP6023-I/P is determined by strict alignment with the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Gain Bandwidth Product: 10 MHz (minimum threshold)
• Supply Voltage Range: Minimum 2.5V, Maximum 5.5V (must encompass or match the original range)
• Operating Temperature: -40°C to 85°C (minimum requirement)

Electrical Performance Boundaries:

• Slew Rate: 6V/µs or greater
• Current - Input Bias: 1 pA or lower
• Voltage - Input Offset: 500 µV or lower
• Current - Supply: 1 mA or lower
• Current - Output / Channel: 25 mA or greater

Packaging Compatibility:

• Through-hole mounting in 8-DIP package format is the primary requirement for direct socket replacement
• Surface-mount alternatives (SC-74A) are listed as functional equivalents but require PCB redesign

Compliance Requirements:

• ROHS3 Compliant
• REACH Unaffected
• Active product status

The identified substitute parts meet these criteria within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

OPA340PA (Texas Instruments) - Direct Socket Replacement:

The OPA340PA is the preferred direct substitute for the MCP6023-I/P. Both devices share identical through-hole 8-DIP packaging, enabling socket-level replacement without PCB modification. The OPA340PA meets all critical electrical parameters: rail-to-rail output, 10 MHz minimum gain-bandwidth product, 2.5V to 5.5V supply range, and -40°C to 85°C operating temperature. The OPA340PA demonstrates superior electrical characteristics with lower input bias current (0.2 pA vs. 1 pA) and lower input offset voltage (150 µV vs. 500 µV). Both devices maintain Active product status and ROHS3 compliance. The OPA340PA is classified under the MicroAmplifier™ series and carries identical ECCN and HTSUS classifications.

NCS20166SN2T1G (onsemi) - Functional Equivalent with Package Redesign:

The NCS20166SN2T1G is a functional equivalent requiring surface-mount PCB redesign. This device meets all electrical substitution criteria: general-purpose amplifier, single circuit, rail-to-rail output, 10 MHz gain-bandwidth product, and 2.5V to 5.5V supply range. The NCS20166SN2T1G offers extended operating temperature range (-40°C to 125°C) and carries AEC-Q100 automotive qualification. The device exhibits superior electrical performance with 50 µV input offset voltage and 6V/µs slew rate. However, the SC-74A surface-mount package (SOT-753) requires PCB layout modification and is not suitable for direct socket replacement in through-hole applications. This substitute is applicable only when PCB redesign is feasible or when automotive-grade qualification is required.

Compliance and Regulatory Alignment:

All three devices maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility across industrial and commercial applications. All devices carry EAR99 ECCN classification and identical HTSUS commodity codes (8542.33.0001).

Frequently Asked Questions (FAQ)

Q: Can the OPA340PA directly replace the MCP6023-I/P without PCB modification?

A: Yes. The OPA340PA shares the identical 8-DIP through-hole package format (0.300", 7.62mm) with the MCP6023-I/P, enabling direct socket replacement. No PCB redesign is required.

Q: What are the key electrical differences between the MCP6023-I/P and OPA340PA?

A: The OPA340PA exhibits lower input bias current (0.2 pA vs. 1 pA) and lower input offset voltage (150 µV vs. 500 µV). The MCP6023-I/P has a higher slew rate (7V/µs vs. 6V/µs). Both devices maintain identical gain-bandwidth product (10 MHz) and supply voltage range (2.5V to 5.5V). The OPA340PA draws slightly less supply current (0.75 mA vs. 1 mA) but provides higher output current capability (50 mA vs. 30 mA).

Q: Why is the NCS20166SN2T1G listed as a substitute if it requires PCB redesign?

A: The NCS20166SN2T1G is a functional electrical equivalent meeting all critical performance parameters. It is listed for applications where PCB redesign is acceptable or planned. The surface-mount SC-74A package offers advantages in high-volume manufacturing and space-constrained designs. The extended temperature range (-40°C to 125°C) and AEC-Q100 automotive qualification make it suitable for automotive and industrial applications.

Q: What is the minimum supply voltage for each device?

A: The MCP6023-I/P and OPA340PA operate at a minimum of 2.5V. The NCS20166SN2T1G requires a minimum of 3V. Applications using 2.5V supply must use either the MCP6023-I/P or OPA340PA.

Q: Are all three devices RoHS compliant?

A: Yes. All three devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial electronics.

Q: What is the temperature operating range for each device?

A: The MCP6023-I/P and OPA340PA operate from -40°C to 85°C. The NCS20166SN2T1G extends this range to -40°C to 125°C, providing broader thermal operating capability for high-temperature applications.

Q: Can the NCS20166SN2T1G be used in automotive applications?

A: Yes. The NCS20166SN2T1G carries AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. The MCP6023-I/P and OPA340PA do not carry automotive qualification.

Q: Which substitute offers the best input offset voltage performance?

A: The NCS20166SN2T1G provides the lowest input offset voltage at 50 µV, followed by the OPA340PA at 150 µV. The MCP6023-I/P specifies 500 µV. Applications requiring precision analog signal conditioning benefit from the lower offset voltage of the onsemi or Texas Instruments devices.
