BA2901YFV-CE2 Equivalent & Substitute Parts

Part Overview

The BA2901YFV-CE2 is a general-purpose quad comparator manufactured by Rohm Semiconductor in a 14-SSOP surface mount package. 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), making it suitable for automotive and industrial applications. The part holds Active product status with AEC-Q100 automotive qualification and ROHS3 compliance.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits alternative packaging or manufacturer options while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA2901YFV-CE2 is determined by the following core parameters:

• Functional Equivalence: Four independent general-purpose comparators with open-collector outputs
• Supply Voltage Compatibility: Operating range must accommodate the application's supply voltage requirements
• Input/Output Electrical Characteristics: Input offset voltage, input bias current, and output current must fall within acceptable design margins
• Package Compatibility: Surface mount packages with identical or compatible pinout and thermal characteristics
• Environmental & Compliance Requirements: Operating temperature range, automotive qualification, and RoHS compliance status

The LMV339IDR and LMV339IPW (both Texas Instruments) meet functional equivalence as quad comparators with open-collector outputs and identical element count. Both devices operate within the -40°C to 125°C temperature range and maintain ROHS3 compliance. However, the LMV339 series operates at reduced supply voltage (2.7V ~ 5.5V) compared to the BA2901YFV-CE2 (2V ~ 36V), limiting substitution to applications within the 2.7V to 5.5V window. Package differences (14-SOIC and 14-TSSOP versus 14-LSSOP) require PCB layout verification for pin compatibility and thermal performance.

Parameter Comparison

Engineering Selection Recommendations

LMV339IDR (14-SOIC Package)

This substitute is functionally equivalent within the 2.7V to 5.5V supply voltage window. The 14-SOIC package (0.154" width) differs from the BA2901YFV-CE2's 14-LSSOP (0.173" width), requiring PCB layout modification. Input offset voltage increases from 4mV to 7mV, and quiescent current rises from 2mA to 350µA. Output current capability increases to 84mA. Product status remains Active with ROHS3 compliance maintained. This option is suitable for applications not requiring the extended supply voltage range of the BA2901YFV-CE2.

LMV339IPW (14-TSSOP Package)

This substitute maintains functional equivalence within the 2.7V to 5.5V supply voltage range. The 14-TSSOP package (0.173" width) matches the BA2901YFV-CE2's package width, simplifying PCB layout compatibility. Electrical characteristics mirror the LMV339IDR variant. Product status is Last Time Buy, indicating limited future availability. This option is suitable for applications where package width compatibility is prioritized and supply voltage remains within the 2.7V to 5.5V specification.

Both LMV339 variants maintain the -40°C to 125°C operating temperature range and ROHS3 compliance required for automotive applications. Selection between these substitutes depends on PCB layout constraints and long-term supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the LMV339IDR or LMV339IPW replace the BA2901YFV-CE2 in all applications?

A: Substitution is limited to applications operating within the 2.7V to 5.5V supply voltage range. The BA2901YFV-CE2 supports extended supply voltages up to 36V (single supply) or ±18V (dual supply), which the LMV339 series does not accommodate. Applications requiring higher supply voltages must retain the BA2901YFV-CE2.

Q: What are the package compatibility considerations?

A: The LMV339IDR uses a 14-SOIC package (0.154" width), requiring PCB redesign compared to the BA2901YFV-CE2's 14-LSSOP (0.173" width). The LMV339IPW uses a 14-TSSOP package (0.173" width), matching the BA2901YFV-CE2's width dimension and simplifying layout compatibility. Pin-to-pin verification is required for both substitutes.

Q: How do electrical performance differences affect circuit design?

A: Input offset voltage increases from 4mV to 7mV in the LMV339 variants, requiring circuit margin verification in precision applications. Quiescent current increases from 2mA to 350µA, affecting power consumption calculations. Output current capability increases to 84mA, providing greater drive capability than the BA2901YFV-CE2's 16mA typical output.

Q: What is the significance of the LMV339IPW's Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has announced end-of-life for this part. While current inventory exists (2100 pcs), future availability is not guaranteed. Long-term designs should consider the LMV339IDR (Active status) or retain the BA2901YFV-CE2 for supply chain continuity.

Q: Are all three parts automotive qualified?

A: The BA2901YFV-CE2 carries AEC-Q100 automotive qualification. The LMV339IDR and LMV339IPW specifications provided do not indicate automotive qualification status. Automotive applications must verify qualification requirements with the manufacturer before substitution.

Q: What compliance certifications apply to these parts?

A: All three parts maintain ROHS3 compliance and REACH Unaffected status. The BA2901YFV-CE2 carries AEC-Q100 automotive qualification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all variants, indicating no moisture sensitivity restrictions during storage or handling.
