BA2901YFV-MGE2 Equivalent & Substitute Parts

Part Overview

The BA2901YFV-MGE2 is a quad general-purpose comparator manufactured by Rohm Semiconductor in a 14-SSOPB surface mount package. This device 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 carries AEC-Q100 automotive qualification and is RoHS3 compliant. As an active product with strong inventory availability (3127 pcs), substitute parts are identified to provide design flexibility, alternative sourcing options, and package variations for specific PCB layout requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA2901YFV-MGE2 is determined by the following core parameters: quad comparator configuration (4 elements), open-collector output topology, supply voltage compatibility, input offset voltage specification, input bias current, output current capability, quiescent current, and operating temperature range. All identified substitute parts maintain the quad comparator architecture and open-collector output type. However, substitution must account for differences in supply voltage range, output current specifications, quiescent current consumption, and package form factor. The AS339MTR-G1 provides the closest electrical match with identical supply voltage range and quiescent current but operates to 85°C maximum. The LMV339ID and LMV339IRUCR variants feature reduced supply voltage range (2.7V ~ 5.5V) and higher quiescent current (350µA) but offer extended propagation delay specification (600ns). The LMV339MX/NOPB operates within 2.7V ~ 5.5V supply range with 300µA quiescent current and is available in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

The AS339MTR-G1 from Diodes Incorporated provides the most direct electrical substitution for applications operating within the 2V to 36V supply range and requiring operation to 85°C. This part maintains identical supply voltage range, quiescent current, and input bias current specifications. The primary design consideration is the reduced maximum operating temperature (85°C versus 125°C) and the package transition from 14-TSSOP to 14-SOIC, which requires PCB layout verification.

For applications requiring extended temperature operation to 125°C, the LMV339ID and LMV339IRUCR from Texas Instruments are suitable alternatives. Both parts maintain the 125°C upper temperature limit but operate within a narrower supply voltage range (2.7V ~ 5.5V). These parts exhibit higher quiescent current (350µA) and higher typical output current (84mA versus 16mA), which may impact power budget calculations. The LMV339IRUCR is packaged in 14-XFQFN, requiring different PCB footprint considerations compared to the original 14-TSSOP.

The LMV339MX/NOPB from National Semiconductor is available in bulk packaging and operates within 2.7V ~ 5.5V supply range with 300µA quiescent current. This part carries active product status and is suitable for high-volume applications where packaging format flexibility is acceptable.

All substitute parts maintain RoHS3 compliance and are suitable for general-purpose comparator applications. Selection should prioritize supply voltage range requirements, operating temperature specifications, and PCB layout constraints specific to the target application.

Frequently Asked Questions (FAQ)

Q: Can the AS339MTR-G1 replace the BA2901YFV-MGE2 in automotive applications?

A: The AS339MTR-G1 is electrically compatible for supply voltages between 2V and 36V and maintains identical quiescent current and input bias current specifications. However, the reduced maximum operating temperature (85°C versus 125°C) must be verified against the specific automotive application requirements. The package change from 14-TSSOP to 14-SOIC requires PCB layout modification.

Q: What are the key differences between the LMV339ID and LMV339IRUCR?

A: Both parts are manufactured by Texas Instruments and share identical electrical specifications including 2.7V ~ 5.5V supply range, 350µA quiescent current, and 600ns propagation delay. The primary difference is packaging: LMV339ID uses 14-SOIC while LMV339IRUCR uses 14-XFQFN (2x2). Package selection depends on PCB space constraints and assembly capabilities.

Q: Why does the BA2901YFV-MGE2 have lower quiescent current than the LMV339 variants?

A: The BA2901YFV-MGE2 specifies 2mA maximum quiescent current, while LMV339 variants specify 300µA to 350µA. This difference reflects different semiconductor process technologies and design approaches. For applications sensitive to quiescent current consumption, the AS339MTR-G1 maintains the 2mA specification while the LMV339 variants require power budget recalculation.

Q: Is the LMV339MX/NOPB suitable for new designs?

A: The LMV339MX/NOPB carries active product status and is RoHS3 compliant. It is suitable for new designs requiring bulk packaging and operation within 2.7V ~ 5.5V supply range. However, the narrower supply voltage range compared to the BA2901YFV-MGE2 must be verified against application requirements.

Q: What packaging considerations apply when substituting the BA2901YFV-MGE2?

A: The original part uses 14-TSSOP (0.173" width). Substitute parts use 14-SOIC (0.154" width) or 14-XFQFN packages. These package changes require PCB footprint modification, trace routing verification, and thermal management reassessment. Consult component datasheets for precise pin assignments and thermal characteristics before PCB layout changes.

Q: Are all substitute parts RoHS3 compliant?

A: All identified substitute parts carry RoHS3 compliance certification. All parts are also REACH unaffected and classified under ECCN EAR99 and HTSUS 8542.39.0001.
