LMP7715MF Equivalent & Substitute Parts

Part Overview

The LMP7715MF is a general-purpose operational amplifier manufactured by Texas Instruments, housed in a SOT-23-5 surface mount package. This device features rail-to-rail output capability, making it suitable for low-voltage analog signal processing applications. The LMP7715MF is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Substitute parts must maintain functional compatibility through matching electrical characteristics and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMP7715MF is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type: General Purpose
• Output configuration: Rail-to-Rail
• Supply voltage range: Minimum 1.8 V to maximum 5.5 V
• Operating temperature range: -40°C to 125°C
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Single circuit configuration

Substitution Logic:

The LMP7715MF/NOPB is a direct equivalent manufactured by Texas Instruments with identical electrical specifications and active product status, differing only in packaging format (Cut Tape & Digi-Reel) and RoHS compliance level.

The MCP6021T-E/OT and MCP6021RT-E/OT (Microchip Technology) are functional substitutes with compatible supply voltage ranges (2.5 V to 5.5 V), rail-to-rail output, SOT-23-5 packaging, and active product status. These devices operate within the same temperature range and maintain general-purpose amplifier functionality.

The NCS2003ASN2T1G (onsemi) is a functional substitute with compatible supply voltage range (1.7 V to 5.5 V), rail-to-rail output, and active product status. Package designation differs as 5-TSOP (SOT-23-5 Thin), and operating temperature range is limited to -40°C to 85°C.

Parameter Comparison

Engineering Selection Recommendations

LMP7715MF/NOPB (Texas Instruments): This part is the recommended direct replacement for the obsolete LMP7715MF. It maintains identical electrical specifications and operating characteristics while offering active product status and ROHS3 compliance. Selection of this part eliminates design modification requirements and ensures long-term supply availability.

MCP6021T-E/OT and MCP6021RT-E/OT (Microchip Technology): These parts are suitable substitutes for applications where the minimum supply voltage requirement of 2.5 V is acceptable. Both devices provide active product status and ROHS3 compliance. The reduced gain bandwidth product (10 MHz versus 17 MHz) and lower slew rate (7 V/µs versus 11.5 V/µs) require circuit performance verification in bandwidth-sensitive applications. These parts are recommended for cost-optimized designs where performance margins exist.

NCS2003ASN2T1G (onsemi): This part is a functional substitute with active product status and ROHS3 compliance. The minimum supply voltage of 1.7 V provides enhanced low-voltage capability. The operating temperature range is limited to -40°C to 85°C, restricting use in applications requiring full -40°C to 125°C operation. The higher slew rate (12.5 V/µs) and output current capability (96 mA) support higher-speed signal processing. Selection requires verification of temperature range compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LMP7715MF/NOPB be used as a direct replacement for the LMP7715MF?

A: Yes. The LMP7715MF/NOPB is a direct equivalent with identical electrical specifications, operating temperature range, and package configuration. The primary differences are packaging format (Cut Tape & Digi-Reel versus standard packaging) and RoHS compliance status (ROHS3 Compliant versus non-compliant). No circuit modifications are required.

Q: What are the key differences between the LMP7715MF and the MCP6021 series?

A: The MCP6021T-E/OT and MCP6021RT-E/OT have lower gain bandwidth product (10 MHz versus 17 MHz), reduced slew rate (7 V/µs versus 11.5 V/µs), higher input offset voltage (500 µV versus 10 µV), and higher input bias current (1 pA versus 0.1 pA). The minimum supply voltage is 2.5 V instead of 1.8 V. These differences require circuit performance evaluation in timing-critical and precision applications.

Q: Is the NCS2003ASN2T1G suitable for all temperature ranges?

A: The NCS2003ASN2T1G operates from -40°C to 85°C, which is narrower than the LMP7715MF range of -40°C to 125°C. This part is not suitable for applications requiring operation above 85°C. Verify application temperature requirements before selection.

Q: Are all substitute parts available in SOT-23-5 packaging?

A: All substitute parts are available in SOT-23-5 or equivalent thin-profile variants (5-TSOP for NCS2003ASN2T1G). Physical footprints are compatible for PCB assembly. The NCS2003ASN2T1G uses a thin-profile variant (TSOT-23-5) which may have slightly different lead dimensions; verify with component datasheets for critical applications.

Q: What is the supply voltage compatibility range for substitution?

A: The LMP7715MF operates from 1.8 V to 5.5 V. The MCP6021 series operates from 2.5 V to 5.5 V, and the NCS2003ASN2T1G operates from 1.7 V to 5.5 V. For applications using supply voltages between 1.8 V and 2.5 V, only the LMP7715MF/NOPB or NCS2003ASN2T1G are suitable.

Q: Which substitute part offers the best performance match?

A: The LMP7715MF/NOPB provides the closest performance match with identical electrical specifications. For applications where performance margins exist, the MCP6021 series offers cost optimization. The NCS2003ASN2T1G provides enhanced low-voltage capability and higher slew rate at the cost of reduced temperature range.
