LMV111M7X Equivalent & Substitute Parts

Part Overview

The LMV111M7X is a general-purpose operational amplifier manufactured by Texas Instruments, housed in a 5-TSSOP (SC-70-5) surface mount package. This device features rail-to-rail output capability and is designed for low-power applications requiring single-circuit amplification. The LMV111M7X is classified as obsolete, necessitating identification of active substitute components that maintain functional and electrical compatibility for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMV111M7X is determined by strict alignment of the following critical parameters:

Package Compatibility: The substitute must use the 5-TSSOP (SC-70-5, SOT-353) surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Functional Classification: The substitute must be a single-circuit general-purpose operational amplifier with rail-to-rail output capability.

Electrical Operating Range: The substitute must support a minimum supply voltage of 2.7 V and accommodate the maximum supply voltage of 5.0 V or higher. Supply current must not exceed 130 µA to maintain power budget compatibility.

Mounting Technology: Surface mount technology is required for compatibility with automated assembly processes.

Compliance Standards: RoHS3 compliance is mandatory for regulatory alignment with the original component.

The LMV321LICT manufactured by STMicroelectronics meets all substitution criteria and is classified as an active product with expanded availability.

Parameter Comparison

Engineering Selection Recommendations

The LMV321LICT is the qualified substitute for the obsolete LMV111M7X. Both components share identical package geometry (5-TSSOP, SC-70-5), functional classification (single-circuit general-purpose rail-to-rail amplifier), and core electrical specifications (2.7 V to 5.0 V supply range, 130 µA supply current).

The LMV321LICT is manufactured by STMicroelectronics and maintains active product status with established supply chain availability (23,200 pieces in stock). Both components are ROHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory and trade compliance equivalence.

The LMV321LICT provides an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) and increased maximum supply voltage tolerance (5.5 V versus 5.0 V), offering enhanced operational flexibility. The substitute exhibits a higher gain bandwidth product (1.3 MHz versus 1.0 MHz) and lower slew rate (0.7 V/µs versus 1.0 V/µs), which are within acceptable performance margins for general-purpose amplifier applications.

Direct PCB footprint substitution is possible without layout modification. No design changes are required for electrical compatibility within the specified supply voltage and temperature operating ranges of the original application.

Frequently Asked Questions (FAQ)

Q: Can the LMV321LICT be used as a direct replacement for the LMV111M7X without PCB modifications?

A: Yes. Both components use the identical 5-TSSOP (SC-70-5, SOT-353) package with matching pin configurations. Direct footprint substitution is possible without layout changes.

Q: What are the key electrical differences between these components?

A: The LMV321LICT provides a higher gain bandwidth product (1.3 MHz versus 1.0 MHz) and extended maximum supply voltage (5.5 V versus 5.0 V). The slew rate is lower (0.7 V/µs versus 1.0 V/µs). Both maintain identical supply current (130 µA) and minimum supply voltage (2.7 V).

Q: Is the LMV321LICT suitable for applications requiring the full -40°C to 85°C temperature range?

A: Yes. The LMV321LICT supports -40°C to 125°C operation, which encompasses the original -40°C to 85°C specification. The substitute is fully compatible for this temperature range.

Q: Are there compliance or regulatory differences between the two parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Q: Why is the LMV111M7X classified as obsolete?

A: The LMV111M7X is no longer in active production. The LMV321LICT is the active equivalent maintained by STMicroelectronics with established supply availability.

Q: What is the inventory status of the substitute part?

A: The LMV321LICT is available in active production with 23,200 pieces in stock, supplied in Cut Tape (CT) and Digi-Reel® packaging formats.

Q: Can the lower slew rate of the LMV321LICT affect circuit performance?

A: The slew rate difference (0.7 V/µs versus 1.0 V/µs) is within acceptable margins for general-purpose amplifier applications. Applications requiring specific slew rate performance should be evaluated against the substitute specification.
