LMV101M7X Equivalent & Substitute Parts

Part Overview

The LMV101M7X 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 operates across a 2.7V to 5V supply voltage range, making it suitable for low-power analog signal processing applications. The product is discontinued at DiGi Electronics, necessitating identification of functionally compatible substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMV101M7X is determined by strict adherence to the following critical parameters:

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

Electrical Specifications: The substitute must support single-channel operation (1 circuit) with rail-to-rail output capability. Supply voltage range must encompass or exceed the original 2.7V to 5V specification to maintain operational compatibility across the intended power supply envelope.

Environmental & Compliance Requirements: Operating temperature range must cover -40°C to 85°C. RoHS3 compliance and REACH unaffected status must be maintained for regulatory alignment.

Functional Classification: While amplifier type may vary (general purpose versus voltage feedback), the substitute must perform equivalent signal amplification functions within the specified electrical and thermal constraints.

The FAN4931IP5X from onsemi satisfies all substitution criteria through identical package geometry, compatible supply voltage range (2.3V to 5.25V), matching operating temperature specification, and equivalent RoHS3 compliance status.

Engineering Selection Recommendations

The FAN4931IP5X qualifies as a direct substitute for the discontinued LMV101M7X based on the following engineering criteria:

Package Equivalence: Both devices utilize the 5-TSSOP (SC-70-5, SOT-353) package, eliminating PCB redesign requirements and enabling direct component replacement.

Supply Voltage Compatibility: The FAN4931IP5X supply voltage range (2.3V to 5.25V) encompasses the LMV101M7X specification (2.7V to 5V), ensuring operation across all intended power supply conditions.

Thermal & Environmental Alignment: Identical operating temperature range (-40°C to 85°C) maintains thermal performance characteristics and environmental compliance.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity.

Performance Characteristics: The FAN4931IP5X exhibits higher slew rate (3V/µs versus 1V/µs) and greater bandwidth (3.7MHz versus 1.6MHz), providing enhanced dynamic performance. Supply current is marginally elevated (200µA versus 130µA), representing a 70µA increase in quiescent consumption.

Selection of the FAN4931IP5X is appropriate for applications where the enhanced bandwidth and slew rate characteristics do not introduce stability or noise concerns in the existing circuit topology.

Frequently Asked Questions (FAQ)

Q: Can the FAN4931IP5X be used as a direct pin-for-pin replacement for the LMV101M7X?

A: Yes. Both devices share identical pinout within the 5-TSSOP (SC-70-5) package configuration. No PCB modifications are required for component substitution.

Q: What are the key differences between these two operational amplifiers?

A: The primary differences are amplifier classification (general purpose versus voltage feedback), slew rate (1V/µs versus 3V/µs), bandwidth (1.6MHz versus 3.7MHz), and supply current (130µA versus 200µA). The FAN4931IP5X provides superior frequency response and transient performance at the cost of increased quiescent power consumption.

Q: Are there any supply voltage compatibility concerns?

A: No. The FAN4931IP5X minimum supply voltage (2.3V) is lower than the LMV101M7X requirement (2.7V), and the maximum rating (5.25V) exceeds the original specification (5V). The substitute operates across a wider voltage envelope, ensuring compatibility with all power supply configurations suitable for the original device.

Q: Do both components meet the same regulatory and compliance standards?

A: Yes. Both the LMV101M7X and FAN4931IP5X are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status for production and distribution.

Q: Will the higher bandwidth of the FAN4931IP5X cause circuit instability?

A: Circuit stability depends on the specific application topology, feedback network, and load conditions. The enhanced bandwidth and slew rate of the FAN4931IP5X may require verification in noise-sensitive or high-frequency applications. Standard operational amplifier stability analysis applies.

Q: What is the moisture sensitivity level difference between these components?

A: The LMV101M7X has MSL 3 (168 hours), while the FAN4931IP5X has MSL 1 (unlimited). The FAN4931IP5X exhibits superior moisture resistance, reducing handling and storage precautions.

Q: Is the FAN4931IP5X available in the same packaging options?

A: The FAN4931IP5X is supplied in Tape & Reel (TR) packaging. Verify packaging format compatibility with your procurement and assembly processes.
