BA10339FV Equivalent & Substitute Parts

Part Overview

The BA10339FV is a general-purpose quad comparator integrated circuit manufactured by Rohm Semiconductor in a 14-SSOP surface-mount package. This device features four independent open-collector comparators suitable for general-purpose signal comparison applications across a wide supply voltage range of 3V to 36V (single supply) or ±1.5V to ±18V (dual supply).

The BA10339FV is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades. Substitute devices must maintain functional equivalence through matching electrical characteristics and compatible packaging configurations.

Substitute Part Grouping Explanation

Substitution of the BA10339FV is determined by the following critical parameters:

Functional Requirements:

Four independent comparators (Number of Elements = 4)
Open-collector output configuration
General-purpose comparator topology

Electrical Compatibility:

Supply voltage range must encompass or match the original specification (3V ~ 36V single supply or ±1.5V ~ 18V dual supply)
Input offset voltage, input bias current, and output current must be within acceptable tolerances for the application
Quiescent current specifications must not exceed design power budgets

Physical Compatibility:

Surface-mount package with 14-pin configuration
Package footprint compatibility (14-LSSOP, 14-TSSOP, or 14-SOIC)
Moisture sensitivity level MSL 1 (unlimited shelf life)

Regulatory Compliance:

RoHS3 compliance for new production applications
REACH compliance status for environmental requirements

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications with different packaging or product status) and similar parts (functionally equivalent with minor electrical variations or different package types).

Engineering Selection Recommendations

Primary Recommendation: BA10339FV-E2

The BA10339FV-E2 is the direct parametric equivalent to the obsolete BA10339FV. This part maintains identical electrical specifications across all measured parameters and operates within the same temperature range (-40°C to 85°C). The BA10339FV-E2 is manufactured by Rohm Semiconductor with active product status and is available in high inventory quantities (30,100 pieces). This part carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The packaging is identical (14-LSSOP), ensuring direct board-level compatibility without design modifications.

Secondary Recommendation: LM2901PT or LM2901YPT

The LM2901 series from STMicroelectronics provides functional equivalence with minor electrical variations. These parts support a slightly reduced supply voltage range (2V to 32V single supply versus 3V to 36V) and operate across an extended temperature range (-40°C to 125°C). The LM2901YPT variant includes AEC-Q100 automotive qualification. Both parts are available in 14-TSSOP packages with active product status and high inventory availability. These devices are suitable for applications where the reduced supply voltage range is acceptable and extended temperature operation is beneficial.

Alternative Recommendation: LM339PT

The LM339PT from STMicroelectronics offers comparable performance with input offset voltage of 5mV at 30V and operates within the 2V to 32V supply range. This part is available in 14-TSSOP packaging with active product status and extensive inventory (84,090 pieces). The LM339PT operates across 0°C to 70°C, which is narrower than the original BA10339FV but suitable for commercial and industrial applications. RoHS3 and REACH compliance are confirmed.

Restricted Recommendation: LMV339 Series (Texas Instruments)

The LMV339 series (LMV339IPWR, LMV339IPW, LMV339ID, LMV339IRUCR) from Texas Instruments exhibits significant electrical differences from the BA10339FV. These parts operate within a restricted supply voltage range of 2.7V to 5.5V, which does not encompass the original 3V to 36V specification. The LMV339 series delivers higher output current (84mA versus 16mA) and lower quiescent current (0.35mA versus 2mA), indicating fundamentally different circuit design. These parts are suitable only for applications operating within the 2.7V to 5.5V range and where higher output current capability is required. Most LMV339 variants carry Last Time Buy status, indicating discontinued or end-of-life product lines.

Not Recommended: LM339APT

The LM339APT operates within a narrower temperature range (0°C to 70°C) compared to the BA10339FV (-40°C to 85°C) and exhibits reduced input bias current (0.1µA versus 0.25µA). This part is suitable only for applications not requiring the full industrial temperature range of the original device.

Frequently Asked Questions (FAQ)

Q: Can BA10339FV-E2 be used as a direct replacement for BA10339FV?

A: Yes. The BA10339FV-E2 is a parametric equivalent with identical electrical specifications and package configuration. The primary difference is product status (active versus obsolete) and packaging format (tape and reel versus bulk). No design modifications are required for board-level substitution.

Q: What is the key limitation of LMV339 series substitutes?

A: The LMV339 series operates within a restricted supply voltage range of 2.7V to 5.5V, which does not encompass the original BA10339FV specification of 3V to 36V. These parts are suitable only for applications operating within the narrower voltage range. Additionally, most LMV339 variants carry Last Time Buy status, indicating limited future availability.

Q: Are LM2901PT and LM339PT interchangeable with BA10339FV?

A: These parts are functionally equivalent but not direct replacements. Both support reduced supply voltage ranges (2V to 32V versus 3V to 36V) and operate at higher quiescent currents (2.5mA versus 2mA). They are suitable for applications where the reduced supply voltage range is acceptable. The LM2901 series offers extended temperature operation (-40°C to 125°C), while LM339 variants operate within 0°C to 70°C.

Q: What package options are available for substitutes?

A: Substitute parts are available in multiple surface-mount packages: 14-LSSOP (BA10339FV-E2), 14-TSSOP (LM2901PT, LM2901YPT, LM339APT, LM339PT, LMV339IPW, LMV339IPWR, LMV339MTX/NOPB), 14-SOIC (LMV339ID), and 14-QFN 2x2 (LMV339IRUCR). Package selection depends on PCB layout constraints and manufacturing capabilities.

Q: Does BA10339FV-E2 meet current regulatory requirements?

A: Yes. BA10339FV-E2 carries RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new production applications.

Q: What is the difference between LM2901YPT and LM2901PT?

A: LM2901YPT includes AEC-Q100 automotive qualification, making it suitable for automotive applications. Both parts share identical electrical specifications and 14-TSSOP packaging. LM2901YPT is preferred for automotive designs requiring qualification documentation.

Q: Can I use LMV339IPWR in place of BA10339FV?

A: LMV339IPWR is functionally equivalent for applications operating within 2.7V to 5.5V supply range. However, it is not suitable for applications requiring the full 3V to 36V range of the original BA10339FV. LMV339IPWR is the only LMV339 variant with active product status; other LMV339 parts carry Last Time Buy designation.

Q: What are the inventory considerations for substitute selection?

A: BA10339FV-E2 offers the highest inventory availability (30,100 pieces) among parametric equivalents. LM339PT provides extensive inventory (84,090 pieces) among STMicroelectronics alternatives. LMV339IPWR (17,300 pieces) is the most available Texas Instruments option with active status. Inventory levels should be verified with suppliers for long-term production planning.

Q: Are there temperature range considerations for substitute selection?

A: Yes. BA10339FV operates -40°C to 85°C. LM2901 series extends to -40°C to 125°C, providing wider temperature coverage. LM339 variants operate 0°C to 70°C, which is narrower. LMV339 series operates -40°C to 125°C. Temperature range selection depends on application environment and thermal requirements.
