Engineering Selection Recommendations

Direct Parametric Equivalents (Highest Compatibility):

LMV393MM/NOPB and LMV393MMX/NOPB are direct parametric equivalents manufactured by Texas Instruments with identical electrical specifications and 8-VSSOP packaging. Both parts are in Active product status with full RoHS3 compliance and MSL 1 rating. These parts provide the most straightforward replacement path for the discontinued LMV393MM.

Upgrade Option with Extended Temperature Range:

LMV393M8-13 (Diodes Incorporated) maintains electrical compatibility with the LMV393MM while offering an extended operating temperature range (-40°C to 125°C) and reduced quiescent current (200µA vs. 300µA). The 8-MSOP package is mechanically compatible with the original 8-VSSOP footprint. This part is suitable for applications requiring enhanced thermal performance.

Alternative Designs with Expanded Supply Voltage Range:

AS393GTR-E1, BA10393F-E2, BA2903FV-E2, BA2903FVM-TR, BA2903SF-E2, and LM393DT support extended supply voltage ranges (2V to 36V or ±1V to ±18V) and are manufactured by Diodes Incorporated, Rohm Semiconductor, and STMicroelectronics respectively. These parts feature lower quiescent current (1mA to 2.5mA) and reduced input offset voltage (5mV @ 5V). Package options include 8-TSSOP, 8-SOIC, 8-LSSOP, and 8-MSOP. Selection depends on specific PCB layout constraints and supply voltage requirements.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH Unaffected status. Moisture sensitivity levels range from MSL 1 (Unlimited) to MSL 3 (168 Hours), affecting storage and handling requirements. Parts with MSL 3 rating require controlled humidity storage and accelerated bake-out procedures prior to reflow soldering.

Frequently Asked Questions (FAQ)

Q: Can LMV393MM/NOPB be used as a direct replacement for LMV393MM?

A: Yes. LMV393MM/NOPB is a parametric equivalent with identical electrical specifications (2.7V to 5.5V supply, 7mV input offset, 84mA output current, 600ns propagation delay) and 8-VSSOP packaging. The primary difference is product status (Active vs. Last Time Buy) and packaging format (Tape & Reel vs. Cut Tape). Pin configuration and functional behavior are identical.

Q: What is the difference between LMV393MMX/NOPB and LMV393MM/NOPB?

A: Both parts are parametric equivalents with identical electrical specifications and 8-VSSOP packaging. The primary difference is packaging format: LMV393MMX/NOPB is supplied in Cut Tape & Digi-Reel format, while LMV393MM/NOPB is supplied in Tape & Reel format. Electrical performance and pin compatibility are identical.

Q: Is LMV393M8-13 compatible with the original LMV393MM design?

A: LMV393M8-13 maintains electrical compatibility with the LMV393MM across the critical parameters: 2.7V to 5.5V supply voltage, 7mV input offset, 84mA output current, and 600ns propagation delay. The 8-MSOP package is mechanically compatible with 8-VSSOP footprints. The upgrade offers extended temperature range (-40°C to 125°C) and lower quiescent current (200µA). Verify PCB layout compatibility before implementation.

Q: Can I use AS393GTR-E1 or BA10393F-E2 as replacements for LMV393MM?

A: These parts are functionally compatible but represent design alternatives rather than direct replacements. Both support extended supply voltage ranges (2V to 36V) and feature lower quiescent current (1mA) and input offset voltage (5mV @ 5V). However, output current is reduced to 16mA @ 5V compared to 84mA for the LMV393MM. Package options differ (8-TSSOP and 8-SOIC respectively). Use these parts only if your application can tolerate reduced output drive capability and different package geometry.

Q: What are the packaging differences among substitute parts?

A: Substitute parts are available in multiple 8-pin surface-mount packages: 8-VSSOP (0.118" width), 8-MSOP (0.110" to 0.118" width), 8-TSSOP (0.173" width), 8-SOIC (0.154" to 0.173" width), 8-LSSOP (0.173" width), and 8-SOP (0.173" width). Package selection affects PCB footprint dimensions and thermal characteristics. Verify PCB layout compatibility and reflow profile requirements for each package variant.

Q: What is the significance of MSL (Moisture Sensitivity Level) ratings?

A: MSL 1 (Unlimited) parts have no moisture sensitivity restrictions and can be stored at room temperature indefinitely. MSL 3 (168 Hours) parts must be stored in controlled humidity environments and require bake-out at 125°C for 24 hours if exposed to humidity exceeding 60% RH for more than 168 hours. Parts with MSL 3 rating include LMV393M8-13, AS393GTR-E1, AZV393GTR-E1, BA2903FV-E2, BA2903FVM-TR, and BA2903SF-E2. Implement appropriate storage and handling procedures to prevent moisture absorption and reflow defects.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, meeting environmental and regulatory requirements for commercial and industrial applications.
