Substitute Part Grouping Explanation
Substitution of the MAX4074BNESA is determined by strict compatibility across the following critical parameters:
Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface-mount package to ensure direct PCB footprint compatibility.
Electrical Compatibility: Substitute parts must operate within the supply voltage range of 2.5V to 5.5V minimum and maximum. The output type must be rail-to-rail to maintain signal swing characteristics. Single-circuit configuration is required.
Performance Envelope: While the MAX4074BNESA operates at lower slew rates (0.1V/µs) and bandwidth (200 kHz), substitute parts with higher performance specifications remain functionally compatible in applications where the original device was used, as they provide equal or superior performance within the same electrical operating envelope.
Thermal and Environmental: Operating temperature range compatibility and RoHS/REACH compliance status are secondary selection criteria based on application requirements.
The six substitute parts identified below satisfy these core compatibility requirements while offering active product status and improved compliance certifications.

Engineering Selection Recommendations
Active Product Status: All six substitute parts carry active product status, ensuring long-term availability and manufacturing support. The MAX4074BNESA is obsolete and no longer manufactured.
Compliance Certifications: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The MAX4074BNESA is RoHS non-compliant.
Supply Voltage Compatibility: All substitute parts operate within or exceed the 2.5V to 5.5V supply range of the original device. MCP6273T-E/SN, MCP6281T-E/SN, and MCP6L1T-E/SN extend the maximum supply voltage to 6.0V, providing additional design flexibility.
Temperature Range Extension: All substitute parts support -40°C to 125°C operating temperature, compared to the MAX4074BNESA's -40°C to 70°C range. This extended range accommodates industrial and automotive applications.
Automotive Grade Option: TSV911IYDT is qualified to AEC-Q100 automotive standards and carries automotive grade designation, suitable for automotive applications requiring enhanced reliability qualification.
Packaging Options: LMP2021MA/NOPB is supplied in Tube packaging; LMP2021MAX/NOPB, MCP6273T-E/SN, MCP6281T-E/SN, MCP6L1T-E/SN, and TSV911IYDT are supplied in Tape & Reel (TR) format; TSV911IDT is supplied in Cut Tape (CT) & Digi-Reel® format.

Frequently Asked Questions (FAQ)
Q: Can I directly replace MAX4074BNESA with any of these substitute parts?
A: Direct replacement is possible from a PCB footprint perspective, as all substitute parts use the 8-SOIC package. However, electrical performance characteristics differ. Verify that the substitute part's performance specifications (slew rate, bandwidth, input offset voltage, supply current) are acceptable for your specific application circuit.
Q: What is the key difference between the LMP2021 series and the general-purpose alternatives?
A: LMP2021MA/NOPB and LMP2021MAX/NOPB are zero-drift amplifiers, meaning they employ internal offset correction to achieve extremely low input offset voltage (0.4 µV) compared to the MAX4074BNESA (200 µV). Zero-drift topology is beneficial for precision measurement and low-level signal conditioning applications. Both parts are functionally equivalent to each other, differing only in packaging (Tube vs. Tape & Reel).
Q: Which substitute offers the best performance improvement over the MAX4074BNESA?
A: TSV911IDT and TSV911IYDT provide the highest slew rate (4.5V/µs) and gain bandwidth product (8 MHz), representing significant performance enhancement. These parts are suitable for applications requiring faster signal response. TSV911IYDT adds automotive-grade qualification for automotive applications.
Q: Are there supply voltage compatibility concerns?
A: All substitute parts operate within the 2.5V to 5.5V range of the MAX4074BNESA. MCP6273T-E/SN, MCP6281T-E/SN, and MCP6L1T-E/SN support up to 6.0V maximum supply, offering additional design margin. Verify your specific supply voltage requirements against each part's minimum specification.
Q: What is the significance of the extended operating temperature range?
A: The MAX4074BNESA operates to 70°C maximum; all substitute parts operate to 125°C. This extended range is critical for industrial, automotive, and high-temperature applications. If your design operates above 70°C, substitution is necessary.
Q: Which substitute part has the lowest supply current consumption?
A: MCP6L1T-E/SN draws 200 µA supply current, the lowest among the substitutes. MCP6273T-E/SN draws 170 µA. For battery-powered or low-power applications, these options minimize power consumption compared to the MAX4074BNESA's 37 µA baseline.
Q: Is the TSV911IYDT suitable for automotive applications?
A: Yes. TSV911IYDT carries automotive grade designation and AEC-Q100 qualification, meeting automotive industry reliability and testing standards. TSV911IDT is the commercial-grade equivalent without automotive qualification.
Q: What packaging format should I select for high-volume production?
A: Tape & Reel (TR) packaging is standard for high-volume surface-mount assembly. LMP2021MAX/NOPB, MCP6273T-E/SN, MCP6281T-E/SN, MCP6L1T-E/SN, and TSV911IYDT are all available in TR format. Cut Tape (CT) & Digi-Reel® (TSV911IDT) and Tube (LMP2021MA/NOPB) are suitable for lower volumes or manual assembly.
Q: Can I use MCP6L1T-E/SN as a direct substitute if my circuit operates above 2.7V?
A: MCP6L1T-E/SN has a minimum supply voltage of 2.7V, compared to the MAX4074BNESA's 2.5V minimum. If your circuit operates between 2.5V and 2.7V, this part is not suitable. Verify your minimum supply voltage requirement before selection.
