Substitute Part Grouping Explanation

Substitution of the LMV393MX is determined by the following critical parameters:

Electrical Compatibility Requirements:

Supply voltage range must encompass or match 2.7V ~ 5.5V
Output type must include open-collector capability
Number of elements must equal 2
Input offset voltage and input bias current must be within acceptable tolerances for the application
Output current capability must support the load requirements
Propagation delay must not exceed application timing constraints

Mechanical Compatibility Requirements:

Package type must be 8-SOIC or compatible surface-mount equivalent
Mounting type must be surface mount
Pin configuration must maintain functional equivalence

Compliance Requirements:

RoHS3 compliance required

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement): LMV393MX/NOPB is the direct parametric equivalent with identical electrical specifications and 8-SOIC packaging. This part maintains active product status and is recommended as the primary replacement for LMV393MX applications requiring no design modification.

Performance Upgrade Option: LMV393S-13 from Diodes Incorporated offers improved propagation delay (450ns versus 600ns) and extended operating temperature range (-40°C to 125°C). This part is suitable for applications requiring faster response times or operation in elevated temperature environments. Output current capability remains equivalent at 84mA.

Extended Supply Voltage Range Alternatives: AS393AMTR-E1, AS393AMTR-G1, AS393MTR-E1, BA2903F-E2, and BA2903FV-E2 support extended supply voltage ranges (2V to 36V or ±1V to ±18V), enabling use in applications requiring higher voltage operation. These parts feature reduced output current (16mA) and increased quiescent current (1mA) compared to the original specification. Selection depends on specific voltage and current requirements.

Package Variants: AS393GTR-E1 provides 8-TSSOP packaging for space-constrained surface-mount applications. AS393P-E1 offers 8-DIP through-hole packaging for legacy or breadboard-compatible designs. Both maintain functional equivalence with appropriate package selection based on PCB layout requirements.

Compliance and Availability: All substitute parts maintain ROHS3 compliance and REACH unaffected status. Product availability varies; AS393MTR-E1 shows highest inventory (354,160 pcs), while AZV393MTR-G1 shows limited availability (3,809 pcs). MSL ratings range from 1 (unlimited) to 3 (168 hours), affecting storage and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can LMV393MX/NOPB be used as a direct replacement for LMV393MX? A: Yes. LMV393MX/NOPB is a parametric equivalent with identical electrical specifications, supply voltage range, output current capability, and 8-SOIC packaging. No design modification is required.

Q: What is the primary difference between LMV393MX and the AS393 series? A: The AS393 series supports extended supply voltage ranges (2V to 36V or ±1V to ±18V) compared to LMV393MX (2.7V to 5.5V). However, AS393 parts feature reduced output current (16mA versus 84mA) and higher quiescent current (1mA versus 300µA). Selection depends on voltage and current requirements of the application.

Q: Is LMV393S-13 compatible with LMV393MX designs? A: LMV393S-13 is functionally compatible with identical supply voltage range and output current. The primary advantage is faster propagation delay (450ns versus 600ns) and extended operating temperature range (-40°C to 125°C). Pin configuration and package footprint are compatible.

Q: What packaging options are available for LMV393MX substitutes? A: Surface-mount options include 8-SOIC (standard), 8-TSSOP (AS393GTR-E1), 8-SOP (BA2903F-E2), and 8-SSOP-B (BA2903FV-E2). Through-hole 8-DIP packaging is available as AS393P-E1. Package selection depends on PCB design requirements and manufacturing capabilities.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements equivalent to the original LMV393MX.

Q: What is the significance of MSL ratings for these parts? A: MSL (Moisture Sensitivity Level) ratings indicate storage and handling requirements. MSL 1 (unlimited) parts have no moisture sensitivity restrictions. MSL 3 (168 hours) parts require controlled storage conditions and must be used within 168 hours of package opening. Select based on manufacturing environment and storage capabilities.

Q: Which substitute offers the highest output current capability? A: LMV393S-13 and AZV393MTR-G1 maintain 84mA output current equivalent to LMV393MX. All other substitutes feature reduced output current of 16mA. Application load requirements determine which option is appropriate.

Q: Can AS393 series parts replace LMV393MX in 5V-only applications? A: Yes. AS393 series parts operate within the 2.7V to 5.5V range required by LMV393MX applications. The extended voltage capability (up to 36V) provides additional design flexibility without compromising 5V operation. However, reduced output current (16mA) must be verified against load requirements.
