Engineering Selection Recommendations

Direct Equivalent (Recommended for Immediate Replacement):

LMV2011MFX/NOPB is the direct functional equivalent of the obsolete LMV2011MFX. This part maintains identical electrical specifications across all parameters while providing active product status and RoHS3 compliance. The only difference is packaging format (Tape & Reel vs. bulk), making this the primary choice for design continuity and minimal qualification effort.

General Purpose Amplifier Substitutes (SOT-23-5 Package):

ISL28113FHZ-T7 and ISL28113FHZ-T7A (Renesas Electronics Corporation) provide direct package and footprint compatibility with the LMV2011MFX. Both parts maintain the SOT-23-5 package, rail-to-rail output, and single-circuit configuration. These devices operate across an extended temperature range (-40°C to 125°C) and feature lower supply current (90 µA vs. 930 µA), making them suitable for power-sensitive applications. Input offset voltage is higher (500 µV vs. 0.12 µV), which may require circuit-level compensation in precision applications.

TS507CLT (STMicroelectronics) offers SOT-23-5 package compatibility with the highest output current capability (128 mA) among SOT-23-5 alternatives. This device features the lowest input offset voltage (25 µV) and operates across the 2.7 V to 5.5 V supply range. Operating temperature range is limited to 0°C to 85°C, matching the original part's minimum temperature specification.

Alternative Package Substitutes (5-SSOP / 5-TSOP):

BU7261G-TR and BU7261SG-TR (Rohm Semiconductor) provide 5-SSOP package alternatives with extended temperature range capability (BU7261SG-TR: -40°C to 105°C). These devices feature the lowest supply current (250 µA) and lowest input bias current (1 pA) among all substitutes. The 5-SSOP package maintains functional compatibility but requires PCB layout modification. BU7261SG-TR supports the widest operating temperature range among Rohm alternatives.

NCS2003ASN2T1G (onsemi) offers 5-TSOP package configuration with the highest slew rate (12.5 V/µs) and gain bandwidth product (7 MHz) among all substitutes. This device provides superior dynamic performance characteristics and the highest output current capability (96 mA). Operating temperature range is -40°C to 85°C.

Higher-Performance Alternatives (Advanced Specifications):

ADA4891-1ARJZ-R7 and ADA4891-1ARJZ-RL (Analog Devices Inc.) represent higher-performance general-purpose amplifiers with significantly enhanced specifications: 210 V/µs slew rate and 240 MHz gain bandwidth product. These devices are suitable for applications requiring higher bandwidth and faster transient response. Supply current is elevated (4.4 mA), and input offset voltage is higher (2.5 mV). Extended temperature range (-40°C to 125°C) and RoHS3 compliance are provided.

AD8628ARTZ-R2 (Analog Devices Inc.) is a zero-drift amplifier variant offering the lowest input offset voltage (1 µV) among all substitutes. This device is optimized for precision measurement applications where offset drift compensation is critical. Operating temperature range extends to -40°C to 125°C. Supply voltage maximum is 5 V (vs. 5.25 V for the original part).

Compliance and Availability:

All recommended substitute parts maintain RoHS3 compliance and active product status. Inventory availability ranges from 2,938 to 50,860 units across the substitute portfolio, ensuring supply chain continuity. The original LMV2011MFX is classified as obsolete with non-compliant RoHS status, making transition to an active substitute mandatory for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q1: Can LMV2011MFX/NOPB be used as a direct replacement for LMV2011MFX?

A: Yes. LMV2011MFX/NOPB is the direct functional equivalent with identical electrical specifications. The only difference is packaging format (Tape & Reel). This part is recommended for immediate replacement due to identical performance characteristics and active product status.

Q2: What are the key differences between SOT-23-5 and 5-SSOP package alternatives?

A: SOT-23-5 and 5-SSOP packages are physically different surface-mount configurations. SOT-23-5 (SC-74A) is smaller and more compact, while 5-SSOP offers slightly different pin spacing. Both are 5-pin packages suitable for single-circuit operational amplifiers. PCB layout and footprint must be modified when switching between these packages. Electrical functionality remains equivalent for parts meeting the specified parameter criteria.

Q3: Which substitute part has the lowest power consumption?

A: ISL28113FHZ-T7 and ISL28113FHZ-T7A feature the lowest supply current at 90 µA, compared to 930 µA for the original LMV2011MFX. BU7261G-TR and BU7261SG-TR offer 250 µA supply current. These low-power alternatives are suitable for battery-powered and energy-constrained applications.

Q4: Are there substitute parts with extended temperature range capability?

A: Yes. ISL28113FHZ-T7, ISL28113FHZ-T7A, ADA4891-1ARJZ-R7, ADA4891-1ARJZ-RL, and AD8628ARTZ-R2 all operate across -40°C to 125°C. BU7261SG-TR extends to -40°C to 105°C. The original LMV2011MFX operates only 0°C to 70°C. Extended temperature range parts are required for industrial and automotive applications.

Q5: Which substitute provides the highest output current capability?

A: TS507CLT (STMicroelectronics) provides 128 mA output current, the highest among all substitutes. NCS2003ASN2T1G offers 96 mA, and ADA4891-1ARJZ variants provide 125 mA. The original LMV2011MFX provides 17 mA. Higher output current capability is necessary for driving low-impedance loads or multiple stages.

Q6: What is the impact of input offset voltage differences on circuit design?

A: Input offset voltage determines DC accuracy in precision applications. The original LMV2011MFX specifies 0.12 µV. Substitutes range from 1 µV (AD8628ARTZ-R2) to 2500 µV (ADA4891 variants). For general-purpose applications, offset voltage differences are negligible. For precision instrumentation, low-offset alternatives (TS507CLT at 25 µV, ISL28113 variants at 500 µV) or zero-drift types (AD8628ARTZ-R2 at 1 µV) are recommended.

Q7: Can ADA4891-1ARJZ variants be used in place of LMV2011MFX?

A: ADA4891-1ARJZ variants meet all mandatory compatibility parameters (general-purpose, single-circuit, rail-to-rail, SOT-23-5 package, 2.7 V to 5.5 V supply). However, these are higher-performance devices with significantly different specifications: 210 V/µs slew rate (vs. 4 V/µs), 240 MHz bandwidth (vs. 3 MHz), and 4.4 mA supply current (vs. 930 µA). These differences may affect circuit behavior in sensitive applications. Use only when higher performance is required or when circuit design accommodates the parameter differences.

Q8: What is the difference between ISL28113FHZ-T7 and ISL28113FHZ-T7A?

A: ISL28113FHZ-T7 and ISL28113FHZ-T7A are functionally identical with identical electrical specifications. The suffix designates different packaging or tape reel configurations. Both operate -40°C to 125°C with 90 µA supply current and 2 MHz gain bandwidth product. Selection between these variants depends on packaging and supply chain requirements rather than electrical performance.

Q9: Is RoHS3 compliance mandatory for substitute selection?

A: Yes. The original LMV2011MFX is RoHS non-compliant. All recommended substitutes maintain RoHS3 compliance, meeting current regulatory requirements for electronic components in most markets. RoHS3 compliance is mandatory for new designs and ongoing production in regulated industries.

Q10: Which substitute is recommended for precision measurement applications?

A: AD8628ARTZ-R2 (zero-drift amplifier, 1 µV input offset) is optimized for precision measurement. TS507CLT (25 µV input offset) provides a lower-cost alternative with acceptable precision. ISL28113FHZ-T7/T7A (500 µV input offset) offers moderate precision with significantly lower supply current. Selection depends on required accuracy, power budget, and cost constraints.
