BA10393F Equivalent & Substitute Parts

Part Overview

The BA10393F is a dual general-purpose comparator manufactured by Rohm Semiconductor in an 8-SOP surface-mount package. This device features open-collector output configuration and operates across a wide supply voltage range of 2V to 36V (single supply) or ±1V to ±18V (dual supply). The BA10393F is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the BA10393F is determined by the following critical parameters: dual-element comparator configuration, open-collector output topology, operating temperature range (-40°C to 85°C), and surface-mount packaging. The supply voltage range and electrical characteristics (input offset, bias current, output current, and quiescent current) define functional compatibility.

Substitute parts are grouped into two categories:

Parametric Equivalent (Direct Replacement): BA10393F-E2 maintains identical electrical specifications and packaging, differing only in product status (active versus obsolete) and packaging format availability.

Similar Functional Equivalents: Parts including AS393P-E1, AZV393GTR-G1, AZV393MTR-G1, LMV393ID, LMV393IDGKR, LMV393IDR, LMV393IPW, LMV393MM, and LMV393MX/NOPB provide dual-element open-collector comparator functionality with compatible operating temperature ranges. These parts differ in package styles (8-DIP, 8-TSSOP, 8-VSSOP, 8-SOIC variants) and specific electrical performance characteristics within acceptable operating parameters.

Engineering Selection Recommendations

Primary Recommendation: BA10393F-E2 is the direct parametric equivalent with identical electrical specifications and package dimensions. This part maintains full compatibility with existing designs while offering active product status and improved availability (105,300 units in stock versus 7,822 for the obsolete BA10393F).

Secondary Recommendations for Supply Voltage Constrained Applications: When the design supply voltage is limited to 2.7V to 5.5V, the following active parts provide functional equivalence with enhanced output current capability (84mA versus 16mA):

LMV393IDR (Texas Instruments, 8-SOIC, 20,247 units in stock)
LMV393IDGKR (Texas Instruments, 8-VSSOP, 1,734 units in stock)
AZV393MTR-G1 (Diodes Incorporated, 8-SOIC, 3,809 units in stock)

Package Variant Alternatives: For applications requiring through-hole mounting, AS393P-E1 (Diodes Incorporated, 8-DIP) provides identical electrical performance to the BA10393F with 40,200 units available.

Compliance Considerations: All recommended active substitutes carry ROHS3 compliance and EAR99 ECCN classification. The BA10393F-E2 is the only substitute maintaining the original supply voltage range (2V to 36V single supply, ±1V to ±18V dual supply).

Frequently Asked Questions (FAQ)

Q: Can BA10393F-E2 be used as a direct replacement for BA10393F?

A: Yes. BA10393F-E2 is the parametric equivalent with identical electrical specifications, operating temperature range, and package dimensions. The only differences are product status (active versus obsolete) and packaging format availability (Cut Tape & Digi-Reel versus standard packaging).

Q: What is the primary difference between BA10393F and the LMV393 series substitutes?

A: The BA10393F operates across a wider supply voltage range (2V to 36V single supply, ±1V to ±18V dual supply), while LMV393 variants are limited to 2.7V to 5.5V. LMV393 parts provide higher output current (84mA versus 16mA) and lower quiescent current (250µA versus 1mA). Selection depends on the application's supply voltage requirements.

Q: Are there package compatibility considerations when substituting the BA10393F?

A: Yes. The BA10393F uses an 8-SOIC package with 0.173" (4.40mm) width. Some substitutes use different SOIC widths (0.154", 3.90mm) or alternative packages (8-TSSOP, 8-VSSOP, 8-DIP). PCB layout and footprint compatibility must be verified before substitution.

Q: Which substitute offers the best inventory availability?

A: BA10393F-E2 has the highest inventory level at 105,300 units in stock, followed by LMV393IDR (Texas Instruments) with 20,247 units. Both are active products with immediate availability.

Q: Can AS393P-E1 replace BA10393F in a surface-mount design?

A: AS393P-E1 provides identical electrical performance and supply voltage range but uses through-hole 8-DIP packaging instead of surface-mount. This substitute is suitable only for designs that can accommodate through-hole components or for prototype/rework applications.

Q: What are the moisture sensitivity level differences among substitutes?

A: BA10393F-E2, LMV393 series (LMV393ID, LMV393IDGKR, LMV393IDR, LMV393IPW), and LMV393MX/NOPB all carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. AZV393GTR-G1 and AZV393MTR-G1 carry MSL 3 (168 Hours), requiring controlled storage and handling conditions.

Q: Are all recommended substitutes RoHS compliant?

A: All active substitute parts listed carry ROHS3 compliance certification. The BA10393F (obsolete) does not have RoHS compliance documentation in the provided specifications.
