MCP6295-E/SN Equivalent & Substitute Parts
Part Overview
The MCP6295-E/SN is a general-purpose operational amplifier manufactured by Microchip Technology, configured as a dual-channel (2 circuit) rail-to-rail output device in an 8-SOIC surface mount package. This device is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The MCP6295-E/SN is specified for operation across -40°C to 125°C and is suitable for low-power analog signal conditioning applications requiring rail-to-rail output capability.
Substitute parts are necessary when the MCP6295-E/SN reaches end-of-life status, when alternative packaging formats are required for manufacturing processes, or when design requirements necessitate different electrical performance characteristics within the general-purpose amplifier category.

Substitute Part Grouping Explanation
Substitution of the MCP6295-E/SN is determined by strict compatibility across the following electrical and mechanical parameters:
Mandatory Compatibility Criteria:
- Dual-channel (2 circuit) configuration
- Rail-to-rail output architecture
- 8-SOIC surface mount package (0.154", 3.90mm width)
- Operating temperature range: -40°C to 125°C minimum
- Supply voltage span: minimum 2.4 V to maximum 6 V overlap
- RoHS3 compliance
- MSL 1 rating
Performance Parameters Defining Substitution Groups:
- Slew rate (7 V/µs baseline)
- Gain bandwidth product (10 MHz baseline)
- Input bias current (1 pA baseline)
- Input offset voltage (3 mV baseline)
- Supply current per channel (1 mA baseline)
- Output current per channel (25 mA baseline)
Substitute parts are grouped by their ability to meet or exceed the minimum electrical requirements while maintaining package and environmental compliance. Parts with lower performance in slew rate, bandwidth, or output current are acceptable only if application requirements permit reduced performance. Parts with superior performance characteristics are direct substitutes without application limitation.

Engineering Selection Recommendations
Active Status Substitutes (Preferred for New Designs):
LMV358MX/NOPB, LMV358M/NOPB, LMV822MX/NOPB, LMV822M/NOPB, MAX4471ESA+, MAX4471ESA+T, and NCS20032DR2G are all classified as Active product status. These parts are recommended for applications where long-term availability and continued manufacturer support are required. All substitute parts maintain RoHS3 compliance and MSL 1 rating consistent with the MCP6295-E/SN.
Last Time Buy Status (Existing Designs Only):
LMV358M and LMV822M are designated Last Time Buy. These parts remain available but will reach end-of-life. Use of these parts is restricted to existing production designs where redesign is not feasible.
Temperature Range Considerations:
The MCP6295-E/SN operates across -40°C to 125°C. LMV358 variants (all versions) and LMV822IDT maintain this full temperature range. LMV822M, LMV822M/NOPB, and LMV822MX/NOPB are limited to -40°C to 85°C and are not suitable for applications requiring operation above 85°C. MAX4471 variants are limited to -40°C to 85°C. NCS20032DR2G maintains the full -40°C to 125°C range.
Supply Voltage Compatibility:
The MCP6295-E/SN requires minimum 2.4 V supply. LMV358 variants require minimum 2.7 V. LMV822 variants and NCS20032DR2G require minimum 2.5 V. MAX4471 variants operate from minimum 1.8 V, providing broader low-voltage compatibility. All parts support maximum 5.5 V to 6 V operation within the MCP6295-E/SN specification.
Performance Trade-offs:
NCS20032DR2G provides superior slew rate (8 V/µs) and output current (96 mA) compared to the MCP6295-E/SN baseline. LMV358 variants offer significantly lower supply current (210 µA per channel versus 1 mA) but reduced bandwidth (1 MHz versus 10 MHz). LMV822 variants provide intermediate performance with 5.6 MHz bandwidth and 2 V/µs slew rate. MAX4471 variants are ultra-low-power devices with minimal slew rate and bandwidth, suitable only for DC or very low-frequency applications.
Frequently Asked Questions (FAQ)
Q: Can LMV358M/NOPB directly replace MCP6295-E/SN in all applications?
A: LMV358M/NOPB is mechanically and electrically compatible in terms of package, pin configuration, and dual-channel rail-to-rail architecture. However, it exhibits significantly reduced bandwidth (1 MHz versus 10 MHz) and slew rate (1 V/µs versus 7 V/µs). Direct substitution is valid only for applications where signal bandwidth does not exceed 1 MHz and slew rate requirements are below 1 V/µs. Verify circuit performance before implementation.
Q: What is the difference between LMV822M, LMV822M/NOPB, and LMV822MX/NOPB?
A: All three variants share identical electrical specifications: 2 V/µs slew rate, 5.6 MHz bandwidth, and -40°C to 85°C operating range. The differences are packaging format only. LMV822M is supplied in bulk (packaging not specified). LMV822M/NOPB is supplied in Tube packaging. LMV822MX/NOPB is supplied in Cut Tape and Digi-Reel format. Select based on manufacturing process requirements. All three are electrically interchangeable.
Q: Why does NCS20032DR2G have a lower minimum supply voltage (1.7 V) than MCP6295-E/SN (2.4 V)?
A: NCS20032DR2G is designed with a lower supply voltage threshold, enabling operation in battery-powered or ultra-low-voltage applications. This does not affect compatibility with the MCP6295-E/SN supply range of 2.4 V to 6 V. The part will function normally across the full MCP6295-E/SN supply specification.
Q: Are MAX4471ESA+ and MAX4471ESA+T electrically identical?
A: Yes. Both parts have identical electrical specifications. The difference is packaging format: MAX4471ESA+ is supplied in Tube, while MAX4471ESA+T is supplied in Tape & Reel (TR). Select based on manufacturing process requirements. Note that both MAX4471 variants have extremely low bandwidth (9 kHz) and slew rate (0.002 V/µs), making them unsuitable for AC signal applications.
Q: Can I use LMV822IDT (STMicroelectronics) as a substitute for MCP6295-E/SN?
A: LMV822IDT is mechanically and electrically compatible. It provides 1.9 V/µs slew rate and 5.5 MHz bandwidth, which are lower than the MCP6295-E/SN but acceptable for many general-purpose applications. LMV822IDT is qualified to AEC-Q100 automotive standard and carries automotive-grade designation. It maintains the full -40°C to 125°C operating range. Use this part when automotive qualification is required or when reduced bandwidth is acceptable.
Q: What is the significance of "Last Time Buy" status for LMV358M and LMV822M?
A: Last Time Buy status indicates that the manufacturer will no longer accept new orders after a specified date, though existing inventory remains available. These parts should not be selected for new product designs. Use Active status parts (LMV358M/NOPB, LMV358MX/NOPB, LMV822M/NOPB, LMV822MX/NOPB) for designs requiring long-term production support.
Q: Is the 8-SOIC package identical across all substitute parts?
A: Yes. All substitute parts use the 8-SOIC package with 0.154" (3.90 mm) width. Pin configuration and footprint are identical. PCB layout and solder reflow profiles are compatible across all listed substitutes.
Q: Which substitute part has the lowest power consumption?
A: MAX4471ESA+ and MAX4471ESA+T have the lowest supply current at 750 nA per channel. However, these parts are designed for DC and very low-frequency applications only (9 kHz bandwidth). For AC signal applications, LMV358 variants offer the next lowest consumption at 210 µA per channel with 1 MHz bandwidth.
Q: Can I substitute MCP6295-E/SN with NCS20032DR2G in a high-temperature application?
A: Yes. NCS20032DR2G maintains the full -40°C to 125°C operating range required by the MCP6295-E/SN. It also provides superior performance with 8 V/µs slew rate and 7 MHz bandwidth. NCS20032DR2G is suitable for high-temperature applications up to 125°C.
