Engineering Selection Recommendations

Primary Substitute: LMP2011MFX/NOPB

The LMP2011MFX/NOPB is the direct equivalent of the obsolete LMP2011MFX, manufactured by Texas Instruments. This part maintains identical electrical specifications and package configuration while offering Active product status. The LMP2011MFX/NOPB is ROHS3 compliant, addressing regulatory requirements not met by the original obsolete part. This is the recommended first choice for direct replacement in existing designs.

Secondary Substitutes: TS507 Series (STMicroelectronics)

The TS507CLT, TS507ILT, and TS507IYLT from STMicroelectronics provide functional substitution with compatible SOT-23-5 packaging and rail-to-rail output. All three variants maintain the required supply voltage range (2.7 V to 5.5 V) and operating temperature specifications. The TS507IYLT includes automotive qualification (AEC-Q100) and is suitable for automotive applications. These parts feature lower slew rate (0.6 V/µs) and gain-bandwidth product (1.9 MHz) compared to the LMP2011MFX, but remain functionally equivalent for general-purpose amplification. All TS507 variants are ROHS3 compliant and Active products.

Alternative Substitutes: Analog Devices ADA4891-1 Series

The ADA4891-1ARJZ-R7 and ADA4891-1ARJZ-RL offer enhanced performance characteristics with significantly higher slew rate (210 V/µs) and gain-bandwidth product (240 MHz). These parts maintain compatible supply voltage range and SOT-23-5 packaging. The ADA4891-1 series exhibits higher supply current (4.4 mA) and output current (125 mA) compared to the LMP2011MFX. These parts are suitable for applications requiring higher bandwidth and faster transient response. Both variants are ROHS3 compliant and Active products.

Alternative Substitutes: Microchip MCP6V71 Series

The MCP6V71T-E/OT and MCP6V71UT-E/OT are zero-drift amplifiers offering superior input offset voltage (8 µV) and input bias current (1 pA) characteristics. These parts maintain SOT-23-5 packaging and rail-to-rail output with compatible supply voltage range. The MCP6V71 series features lower supply current (170 µA) and slew rate (1 V/µs) compared to the LMP2011MFX. These parts are suitable for precision measurement applications requiring minimal offset drift. Both variants are ROHS3 compliant and Active products.

Alternative Substitute: onsemi NCS2003ASN2T1G

The NCS2003ASN2T1G provides general-purpose amplification with higher slew rate (12.5 V/µs) and gain-bandwidth product (7 MHz) in a compatible SOT-23-5 package. This part supports lower minimum supply voltage (1.7 V) but has a reduced maximum operating temperature of 85°C. The NCS2003ASN2T1G is ROHS3 compliant and Active. This part is suitable for applications not requiring the full -40°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can the LMP2011MFX be directly replaced with LMP2011MFX/NOPB?

A: Yes. The LMP2011MFX/NOPB is the direct equivalent with identical electrical specifications and SOT-23-5 package configuration. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). This is the recommended replacement for existing designs.

Q: What are the key differences between the LMP2011MFX and TS507 series substitutes?

A: The TS507 series (TS507CLT, TS507ILT, TS507IYLT) maintains compatible supply voltage range, rail-to-rail output, and SOT-23-5 packaging. The primary differences are lower slew rate (0.6 V/µs vs. 4 V/µs) and lower gain-bandwidth product (1.9 MHz vs. 3 MHz). Input bias current is significantly higher (8 nA vs. 3 pA). These differences are acceptable for general-purpose amplification applications where bandwidth and input bias current are not critical parameters.

Q: Are the ADA4891-1 series parts suitable for direct replacement?

A: The ADA4891-1ARJZ-R7 and ADA4891-1ARJZ-RL are functionally compatible in SOT-23-5 packaging and supply voltage range. However, these parts feature significantly higher performance specifications (210 V/µs slew rate, 240 MHz bandwidth) and higher supply current (4.4 mA vs. 930 µA). These parts are suitable for applications requiring enhanced bandwidth and faster response, but may introduce unnecessary power consumption in low-speed applications.

Q: What is the difference between TS507CLT, TS507ILT, and TS507IYLT?

A: All three variants share identical electrical specifications and SOT-23-5 packaging. The primary differences are operating temperature range and automotive qualification. TS507CLT operates 0°C to 85°C. TS507ILT operates -40°C to 125°C. TS507IYLT operates -40°C to 125°C with AEC-Q100 automotive qualification. Select TS507IYLT for automotive applications requiring full temperature range coverage.

Q: Can MCP6V71 series parts replace the LMP2011MFX in all applications?

A: The MCP6V71T-E/OT and MCP6V71UT-E/OT are zero-drift amplifiers with superior offset voltage specifications (8 µV vs. 0.12 µV). These parts are compatible in package and supply voltage range. However, they feature lower slew rate (1 V/µs vs. 4 V/µs) and lower gain-bandwidth product (2 MHz vs. 3 MHz). These parts are suitable for precision measurement applications where offset drift is critical, but may not be suitable for applications requiring higher bandwidth.

Q: What is the operating temperature limitation of NCS2003ASN2T1G?

A: The NCS2003ASN2T1G operates from -40°C to 85°C, which does not cover the full -40°C to 125°C range of the LMP2011MFX. This part is suitable only for applications with maximum operating temperature of 85°C or lower. For applications requiring operation to 125°C, select TS507ILT, TS507IYLT, or other substitutes with extended temperature range.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant. The original LMP2011MFX is RoHS non-compliant. The LMP2011MFX/NOPB and all other active substitutes meet current RoHS3 requirements, making them suitable for new designs and applications with RoHS compliance mandates.

Q: What is the moisture sensitivity level for all parts?

A: All parts, including the LMP2011MFX and all substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly.
