LMV393S-13 Equivalent & Substitute Parts

Part Overview

The LMV393S-13 is a dual general-purpose comparator manufactured by Diodes Incorporated in an 8-SO surface mount package. This device features open-collector output configuration and operates across a 2.7V to 5.5V supply voltage range, making it suitable for low-voltage analog signal comparison applications. The part is currently in active production status with 5343 units in stock. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters while maintaining compatibility with the original application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LMV393S-13 are qualified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Parameters:

• Dual comparator configuration (2 elements)
• Open-collector output topology
• Supply voltage range compatibility or broader range
• Input offset voltage within acceptable tolerance
• Input bias current specification
• Surface mount packaging with compatible pinout
• Operating temperature range coverage
• RoHS3 compliance and active product status

Substitution Logic: Parts are grouped as direct substitutes when they maintain the core functional parameters (dual comparator, open-collector output) and operate within overlapping or broader supply voltage specifications. Package form factor differences are noted where mechanical constraints may apply. Parts with broader supply voltage ranges (2V ~ 36V) are qualified as substitutes provided all other electrical parameters remain compatible with the original application envelope.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Preferred):

LMV393IDGKR (Texas Instruments) and BA2903F-E2 (Rohm Semiconductor) are the primary substitutes. Both maintain the identical supply voltage range (2.7V ~ 5.5V for LMV393IDGKR; 2V ~ 36V for BA2903F-E2), matching input bias current specifications, and full operating temperature range (-40°C ~ 125°C). Both are active production parts with ROHS3 compliance and MSL 1 rating. LMV393IDGKR preserves the 84mA output current specification. BA2903F-E2 provides broader supply voltage flexibility with reduced quiescent current (1mA vs. 200µA).

Tier 2 - Functional Substitutes (Extended Range):

BA10393F-E2 (Rohm Semiconductor) and LM393DT (STMicroelectronics) offer broader supply voltage ranges (2V ~ 36V) suitable for applications requiring extended voltage operation. Both maintain dual comparator, open-collector configuration with compatible input specifications. BA10393F-E2 operates to -40°C ~ 85°C; LM393DT operates to 0°C ~ 70°C. Both are active production parts with ROHS3 compliance.

Not Recommended:

BA2903WF-E2 carries "Not For New Designs" product status and should not be selected for new applications despite electrical compatibility.

Package Considerations:

LMV393IDGKR uses 8-TSSOP (3.00mm width) versus the original 8-SOIC (3.90mm). BA10393F-E2, BA2903F-E2, and BA2903WF-E2 use 8-SOIC (4.40mm width). PCB layout and thermal management requirements must account for these dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can BA10393F-E2 replace LMV393S-13 in all applications?

A: BA10393F-E2 is electrically compatible for dual comparator functionality with open-collector output. However, the operating temperature range is limited to -40°C ~ 85°C versus the original -40°C ~ 125°C. Applications requiring operation above 85°C require BA2903F-E2 or BA2903WF-E2 instead. Package width differs (4.40mm vs. 3.90mm), requiring PCB layout verification.

Q: What is the significance of the broader supply voltage range in BA2903F-E2?

A: BA2903F-E2 operates across 2V ~ 36V (or ±1V ~ 18V dual supply), compared to LMV393S-13's 2.7V ~ 5.5V range. This broader specification allows use in applications with variable or higher supply voltages. The core comparator functionality remains equivalent within the overlapping 2.7V ~ 5.5V window.

Q: Why does LMV393IDGKR have different propagation delay (600ns vs. 450ns)?

A: Propagation delay variation reflects manufacturing process differences between Texas Instruments and Diodes Incorporated. Both values fall within acceptable comparator response times for general-purpose applications. Applications with strict timing requirements must evaluate the 150ns difference against circuit specifications.

Q: Is MSL rating important for substitution?

A: Yes. LMV393S-13 carries MSL 3 (168 hours), requiring controlled moisture exposure during storage and assembly. All substitute parts carry MSL 1 (Unlimited), providing superior moisture tolerance and reducing handling constraints during manufacturing and storage.

Q: Can LM393DT be used in place of LMV393S-13?

A: LM393DT is functionally compatible as a dual open-collector comparator. However, the operating temperature range is restricted to 0°C ~ 70°C, eliminating low-temperature operation below 0°C and high-temperature operation above 70°C. This part is suitable only for applications within this narrower temperature envelope.

Q: What are the output current implications when selecting a substitute?

A: LMV393S-13 and LMV393IDGKR both provide 84mA typical output current at 5V. BA10393F-E2, BA2903F-E2, and BA2903WF-E2 provide 16mA, and LM393DT provides 18mA. Applications requiring high output current drive (above 20mA) must use LMV393S-13 or LMV393IDGKR. Lower-current applications can use any substitute without performance impact.
