Substitute Part Grouping Explanation

Substitute parts for the LMV393M are classified into three categories based on substitution criteria:

Direct Substitutes (Same Manufacturer, Active Status) Direct substitutes maintain identical electrical specifications and packaging while offering improved part status. The LMV393M/NOPB from Texas Instruments is a direct equivalent with active product status, identical supply voltage range (2.7V ~ 5.5V), matching input offset voltage (7mV @ 5V), and equivalent output current (84mA @ 5V). This part differs only in part status classification and packaging designation.

Functional Equivalents (Alternative Manufacturers, 8-SOIC Package) Functional equivalents from alternative manufacturers provide comparable performance within the same 8-SOIC package footprint. These include:

• LMV393S-13 (Diodes Incorporated): Maintains 2.7V ~ 5.5V supply range, 7mV input offset, 84mA output current, with improved propagation delay (450ns vs. 600ns) and lower quiescent current (200µA vs. 300µA). Operating temperature extends to 125°C.
• AZV393MTR-G1 (Diodes Incorporated): Matches 2.5V ~ 5.5V supply range, 7mV input offset, 84mA output current, with reduced quiescent current (200µA).
• LMV393DR2G (onsemi): Provides 2.7V ~ 5V supply range with open-drain output, 9mV input offset, and 84mA output current.

Extended-Range Substitutes (Wider Supply Voltage, Alternative Packages) Extended-range substitutes offer broader operating specifications suitable for applications requiring wider supply voltage ranges or different package options:

• AS393GTR-E1 (Diodes Incorporated): 8-TSSOP package with 2V ~ 36V / ±1V ~ 18V supply range, 5mV input offset, reduced output current (16mA @ 5V), and lower quiescent current (1mA).
• LM393DT (STMicroelectronics): 8-SOIC package with 2V ~ 36V / ±1V ~ 18V supply range, 5mV input offset @ 30V, rail-to-rail output, extended operating temperature (0°C ~ 70°C).
• LMV393M8-13 (Diodes Incorporated): 8-MSOP package with 2.7V ~ 5.5V supply range, 7mV input offset, 84mA output current, extended operating temperature (-40°C ~ 125°C).

Premium Substitutes (Enhanced Performance Characteristics) Premium substitutes provide superior electrical performance characteristics:

• MAX9022ASA+ / MAX9022ASA+T (Analog Devices Inc./Maxim Integrated): 8-SOIC package with 2.5V ~ 5.5V / ±1.25V ~ 2.75V supply range, superior input offset (1mV @ 5V), extremely low input bias current (0.003µA @ 5V), CMRR 100dB, PSRR 80dB, extended operating temperature (-40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Active Product Status Select LMV393M/NOPB from Texas Instruments. This part maintains identical electrical specifications and 8-SOIC packaging as the obsolete LMV393M while offering active product status and unlimited moisture sensitivity rating (MSL 1). This selection ensures design continuity with no circuit modifications required.

For Improved Performance within Standard Supply Range Select LMV393S-13 from Diodes Incorporated. This 8-SOIC part maintains the 2.7V ~ 5.5V supply range and 7mV input offset specification while providing improved propagation delay (450ns vs. 600ns) and reduced quiescent current (200µA vs. 300µA). Extended operating temperature range (-40°C ~ 125°C) supports broader thermal applications. Active product status and ROHS3 compliance are confirmed.

For Space-Constrained Applications Select LMV393M8-13 from Diodes Incorporated. This 8-MSOP package variant reduces board footprint while maintaining 2.7V ~ 5.5V supply range, 7mV input offset, and 84mA output current. Extended operating temperature (-40°C ~ 125°C) and active product status support long-term availability.

For Extended Supply Voltage Range Applications Select LM393DT from STMicroelectronics or AS393GTR-E1 from Diodes Incorporated. Both parts support 2V ~ 36V / ±1V ~ 18V supply ranges with active product status and ROHS3 compliance. LM393DT maintains 8-SOIC packaging with rail-to-rail output capability. AS393GTR-E1 uses 8-TSSOP packaging with reduced output current (16mA @ 5V) and quiescent current (1mA), suitable for low-power applications.

For Premium Performance Requirements Select MAX9022ASA+ or MAX9022ASA+T from Analog Devices Inc./Maxim Integrated. These parts deliver superior input offset voltage (1mV @ 5V), extremely low input bias current (0.003µA @ 5V), and high CMRR/PSRR specifications (100dB/80dB). Extended operating temperature (-40°C ~ 125°C) and active product status support demanding applications. MAX9077ESA+ provides push-pull rail-to-rail output with comparable performance characteristics.

Compliance and Certification Basis All recommended substitute parts maintain ROHS3 compliance and EAR99 ECCN classification consistent with the original LMV393M. Moisture sensitivity levels range from MSL 1 (unlimited) to MSL 3 (168 hours), with MSL 1 parts recommended for applications with extended storage or high-humidity environments. REACH compliance status is confirmed as unaffected for all active substitute parts.

Frequently Asked Questions (FAQ)

Q: Can LMV393M/NOPB be used as a direct replacement for LMV393M? A: Yes. LMV393M/NOPB is a direct equivalent with identical electrical specifications (2.7V ~ 5.5V supply, 7mV input offset, 84mA output current, 600ns propagation delay) and 8-SOIC packaging. The primary difference is active product status versus obsolete classification. No circuit modifications are required.

Q: What is the key difference between LMV393S-13 and the original LMV393M? A: LMV393S-13 maintains the same supply voltage range (2.7V ~ 5.5V) and input offset specification (7mV @ 5V) but offers improved performance: propagation delay reduced from 600ns to 450ns, quiescent current reduced from 300µA to 200µA, and operating temperature extended to 125°C. Output current remains 84mA @ 5V.

Q: Are the MAX9022 and MAX9077 series suitable for direct replacement? A: MAX9022 and MAX9077 series are functional alternatives, not direct replacements. These parts offer superior performance characteristics (1mV input offset, extremely low input bias current, high CMRR/PSRR) but differ in output type (CMOS/TTL vs. open-collector) and quiescent current specifications. Circuit evaluation is required to confirm compatibility with existing designs.

Q: What packaging options are available for LMV393 equivalents? A: Substitute parts are available in multiple packages: 8-SOIC (0.154", 3.90mm width) for LMV393M/NOPB, LMV393S-13, AZV393MTR-G1, LMV393DR2G, LM393DT, MAX9022, and MAX9077; 8-TSSOP (0.173", 4.40mm width) for AS393GTR-E1; and 8-MSOP (0.118", 3.00mm width) for LMV393M8-13. Package selection depends on board layout constraints and thermal requirements.

Q: Which substitute part supports the widest supply voltage range? A: LM393DT and AS393GTR-E1 both support 2V ~ 36V single supply or ±1V ~ 18V dual supply configurations, compared to the original LMV393M range of 2.7V ~ 5.5V. These extended-range parts are suitable for applications requiring operation across broader voltage specifications.

Q: What is the significance of MSL (Moisture Sensitivity Level) ratings? A: MSL 1 (unlimited) indicates no moisture sensitivity restrictions and supports indefinite shelf storage. MSL 3 (168 hours) requires baking before reflow soldering if the part has been exposed to moisture for more than 168 hours. For applications with extended storage or high-humidity environments, MSL 1 parts (LMV393M/NOPB, LM393DT, MAX9022 series) are recommended.

Q: Can LMV393DR2G be used as a substitute despite different output type? A: LMV393DR2G features open-drain output versus the original LMV393M open-collector/CMOS/TTL configuration. While electrical specifications are similar (2.7V ~ 5V supply, 84mA output current), the output type difference requires circuit evaluation. Open-drain output may require different pull-up resistor configurations compared to open-collector designs.

Q: What is the advantage of selecting LMV393M8-13 in 8-MSOP packaging? A: LMV393M8-13 reduces board footprint by approximately 40% compared to 8-SOIC packaging while maintaining identical electrical specifications (2.7V ~ 5.5V supply, 7mV input offset, 84mA output current, 600ns propagation delay). Extended operating temperature (-40°C ~ 125°C) and active product status support long-term design continuity in space-constrained applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All recommended substitute parts maintain ROHS3 compliance consistent with the original LMV393M. REACH compliance status is confirmed as unaffected for all active substitute parts, supporting regulatory requirements across multiple jurisdictions.
