BA10393N Equivalent & Substitute Parts

Part Overview

The BA10393N is a dual general-purpose comparator IC manufactured by Rohm Semiconductor in 8-SIP through-hole packaging. This device features open-collector outputs and operates across a wide supply voltage range of 2V to 36V (single supply) or ±1V to ±18V (dual supply). The BA10393N is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. Substitute comparators must maintain functional equivalence in output type, element count, and core electrical characteristics while accommodating modern packaging preferences and active product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA10393N is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Dual comparator configuration (2 elements)
• Open-collector output topology
• Supply voltage range compatibility: minimum 2V single supply or ±1V dual supply
• Input offset voltage ≤ 5mV @ 5V
• Input bias current ≤ 0.25µA @ 5V
• Output current capability ≥ 16mA @ 5V
• Quiescent current ≤ 1mA
• Operating temperature range -40°C to 85°C
• RoHS3 compliance

Packaging Considerations: The BA10393N uses 8-SIP through-hole packaging. Modern equivalents are available in surface-mount packages (8-SOIC, 8-TSSOP, 8-MSOP, 8-VSSOP) that maintain electrical equivalence but require PCB redesign for through-hole to surface-mount conversion.

Substitute Categories:

Category A - Full Electrical & Temperature Range Match (2V ~ 36V / ±1V ~ 18V):

• AS393AMTR-G1 (Diodes Incorporated, 8-SOIC)
• AS393GTR-E1 (Diodes Incorporated, 8-TSSOP)
• AS393MMTR-G1 (Diodes Incorporated, 8-MSOP)
• NJM2407R-TE1 (Nisshinbo Micro Devices Inc., 8-VSP)

Category B - Restricted Supply Voltage Range (2.5V ~ 5.5V):

• AZV393MTR-E1 (Diodes Incorporated, 8-SOIC)
• AZV393GTR-E1 (Diodes Incorporated, 8-TSSOP)
• AZV393MMTR-E1 (Diodes Incorporated, 8-MSOP)

Category C - Restricted Supply Voltage Range (2.7V ~ 5.5V):

• LMV393IPWR (National Semiconductor, 8-TSSOP)
• LMV393IDDUR (Texas Instruments, 8-VSSOP)

Category D - Restricted Supply Voltage Range (3V ~ 32V / ±1.5V ~ 16V):

• LM393F-E2 (Rohm Semiconductor, 8-SOP)

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement (Full Supply Range Compatibility):

Select AS393GTR-E1 or AS393MMTR-G1 from Diodes Incorporated for applications requiring the complete 2V to 36V supply voltage range. Both parts maintain identical electrical specifications to the BA10393N, including 16mA output current and 1mA quiescent current. AS393GTR-E1 in 8-TSSOP packaging offers the most compact surface-mount footprint, while AS393MMTR-G1 in 8-MSOP provides an alternative surface-mount option. Both are active products with RoHS3 compliance.

For Rohm Semiconductor Continuity:

LM393F-E2 from Rohm Semiconductor provides a direct manufacturer alternative in active product status. This part operates across 3V to 32V (single supply) or ±1.5V to ±16V (dual supply), which covers most industrial applications. The 8-SOP surface-mount package requires PCB redesign from the original 8-SIP through-hole configuration.

For Restricted Supply Voltage Applications (2.5V ~ 5.5V):

AZV393 series parts (AZV393MTR-E1, AZV393GTR-E1, AZV393MMTR-E1) from Diodes Incorporated are suitable only for applications operating within the 2.5V to 5.5V range. These parts offer higher output current capability (84mA) compared to the BA10393N (16mA), making them suitable for applications requiring increased drive capability within the restricted voltage window.

For Low-Voltage Specialized Applications (2.7V ~ 5.5V):

LMV393IPWR and LMV393IDDUR are restricted to 2.7V to 5.5V operation and are suitable only for low-voltage applications. LMV393IDDUR carries Last Time Buy status from Texas Instruments, indicating limited future availability.

Compliance & Availability:

All recommended substitutes maintain RoHS3 compliance and REACH unaffected status. AS393AMTR-G1, AS393GTR-E1, and AS393MMTR-G1 from Diodes Incorporated demonstrate the highest inventory levels (18,400 to 25,475 units), ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can I use AZV393 series parts as a direct replacement for BA10393N?

A: AZV393 series parts are not direct replacements for applications requiring the full 2V to 36V supply range. These parts operate only within 2.5V to 5.5V. Use AZV393 parts only if your application operates exclusively within this restricted voltage window.

Q: What is the primary difference between AS393 and AZV393 series comparators?

A: The AS393 series maintains the BA10393N supply voltage range (2V ~ 36V / ±1V ~ 18V) with 16mA output current. The AZV393 series is restricted to 2.5V ~ 5.5V operation but provides higher output current (84mA) and faster propagation delay (450ns). Select based on your supply voltage requirements and output current needs.

Q: Is the LM393F-E2 a suitable replacement for through-hole applications?

A: LM393F-E2 uses 8-SOP surface-mount packaging, not through-hole. If your PCB requires through-hole mounting, this part necessitates board redesign. For through-hole compatibility, consider using AS393AMTR-G1 or other surface-mount alternatives with appropriate adapter modules or board redesign.

Q: What packaging options are available for BA10393N substitutes?

A: Substitutes are available in 8-SOIC, 8-TSSOP, 8-MSOP, 8-VSSOP, and 8-SOP surface-mount packages. The original BA10393N uses 8-SIP through-hole packaging. All modern substitutes require surface-mount PCB design or through-hole adapter solutions.

Q: Can I substitute LMV393IDDUR in new designs?

A: LMV393IDDUR carries Last Time Buy status from Texas Instruments, indicating discontinued production. This part is not recommended for new designs. Use active product alternatives such as LMV393IPWR, AS393GTR-E1, or AS393MMTR-G1 instead.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: dual comparator configuration, open-collector output type, supply voltage range overlap, input offset voltage specification, input bias current specification, output current capability, quiescent current specification, and operating temperature range (-40°C to 85°C). All substitute parts listed maintain these core parameters within specified tolerances.

Q: Does NJM2407R-TE1 provide full compatibility with BA10393N?

A: NJM2407R-TE1 operates within 2V to 20V (single supply) or ±1V to ±10V (dual supply), which is narrower than the BA10393N range (2V ~ 36V / ±1V ~ 18V). Use NJM2407R-TE1 only if your application operates within its specified voltage window. For applications requiring the full 36V capability, select AS393 series parts instead.
