BA2902FV-E2 Equivalent & Substitute Parts
Part Overview
The BA2902FV-E2 is a general-purpose operational amplifier manufactured by Rohm Semiconductor, configured as a 4-circuit integrated circuit in a 14-SSOP-B surface mount package. This device operates across a supply voltage range of 3V to 32V and maintains functionality across an extended temperature range of -40°C to 125°C. The part is currently in active production status with substantial inventory availability (10,300 units).
Substitute parts are necessary when the BA2902FV-E2 becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications permit operation with equivalent electrical characteristics. Substitute selection must maintain compatibility with the four-circuit amplifier configuration, surface mount mounting type, and the specified electrical performance parameters.

Substitute Part Grouping Explanation
Substitution of the BA2902FV-E2 is determined by the following critical parameters:
Mandatory Compatibility Criteria:
- Four-circuit operational amplifier configuration
- Surface mount mounting type
- Supply voltage range minimum of 3V and maximum of at least 26V
- Operating temperature range encompassing -40°C to 125°C
- RoHS3 compliance and MSL 1 rating
- Package case width of 4.40mm (14-LSSOP or 14-TSSOP formats)
Electrical Performance Parameters:
- Input bias current of 20 nA or lower
- Input offset voltage of 3 mV or lower
- Output current per channel of 30 mA or higher
- Gain bandwidth product of 500 kHz or higher
Substitute parts are grouped into two categories based on packaging format: Cut Tape (CT) & Digi-Reel® packaging matching the original format, and Tape & Reel (TR) packaging for alternative supply methods. Parts with obsolete or last-time-buy status are included where electrical and mechanical specifications remain compatible, though active-status alternatives are preferred for new designs.

Engineering Selection Recommendations
Primary Substitutes (Active Status):
LM224DTBR2G and LM2902DTBR2G from onsemi are active-status alternatives with identical package dimensions (14-TSSOP, 0.173", 4.40mm width) and compatible electrical specifications. Both devices maintain the 4-circuit configuration, 3V to 32V supply range, and -40°C to 125°C operating temperature envelope. LM2902DTBR2G specifically extends the operating temperature to 105°C and is available in Cut Tape & Digi-Reel® packaging, matching the original supply format.
LM2902KAVQPWR from Texas Instruments is an active-status part with AEC-Q100 automotive qualification. This device maintains full compatibility with the BA2902FV-E2 across all critical parameters, including the -40°C to 125°C temperature range and 3V to 30V supply span. The automotive-grade qualification provides additional reliability assurance for applications requiring automotive-level component standards.
Secondary Substitutes (Last Time Buy / Obsolete Status):
LM2902KDB and LM2902KPW from Texas Instruments carry Last Time Buy status. These parts maintain electrical compatibility but feature a wider 14-SSOP package (0.209", 5.30mm width) in the case of LM2902KDB, requiring PCB layout modification. LM2902KPW maintains the 14-TSSOP format and is suitable for applications where inventory consolidation is acceptable.
LM2902KPWR, LM2902KVQPWR, LM2902PT, LM2902PW, and LM2902PWR are obsolete or not-for-new-designs parts from Rohm Semiconductor and Texas Instruments. These devices maintain electrical and mechanical compatibility with the BA2902FV-E2 but should not be selected for new design implementations. These parts are listed for reference in legacy system maintenance and component replacement scenarios only.
Compliance and Certification:
All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001, maintaining consistent regulatory and tariff classification with the original BA2902FV-E2.
Frequently Asked Questions (FAQ)
Q: Can LM224DTBR2G be used as a direct replacement for BA2902FV-E2?
A: LM224DTBR2G is electrically compatible with the BA2902FV-E2 across all critical parameters: 4-circuit configuration, 3V to 32V supply range, and -40°C to 125°C operating temperature. However, the operating temperature minimum is -25°C rather than -40°C, which may restrict use in applications requiring full -40°C operation. Package dimensions are identical (14-TSSOP, 0.173", 4.40mm width). Verify application temperature requirements before selection.
Q: What is the difference between 14-LSSOP and 14-TSSOP packages?
A: Both packages maintain identical width dimensions (0.173", 4.40mm) and are mechanically compatible with the same PCB footprints. The primary difference is in the lead configuration and thermal characteristics. The BA2902FV-E2 uses 14-LSSOP format, while most substitute parts use 14-TSSOP format. Both formats are surface mount packages suitable for automated assembly processes.
Q: Why does LM2902KDB have a different package width (0.209", 5.30mm)?
A: LM2902KDB uses a 14-SSOP package format rather than the 14-TSSOP format of the BA2902FV-E2. This wider package (5.30mm versus 4.40mm) requires PCB layout modification and is not a direct footprint replacement. This part is listed as Last Time Buy status and should not be selected for new designs unless existing PCB layouts accommodate the wider package.
Q: Is LM2902KAVQPWR suitable for automotive applications?
A: LM2902KAVQPWR carries AEC-Q100 automotive qualification and is designated as an automotive-grade component. This part is suitable for automotive applications requiring automotive-level component standards. All other substitute parts lack automotive qualification and should not be used in automotive applications without additional qualification review.
Q: Can obsolete parts like LM2902PWR be used in new designs?
A: LM2902PWR and other obsolete-status parts should not be selected for new design implementations. These parts are listed for reference in legacy system maintenance and component replacement scenarios only. For new designs, select from active-status alternatives: LM224DTBR2G, LM2902DTBR2G, or LM2902KAVQPWR.
Q: What is the significance of the input bias current difference between BA2902FV-E2 (20 nA) and LM224DTBR2G (90 nA)?
A: The BA2902FV-E2 specifies 20 nA input bias current, while LM224DTBR2G specifies 90 nA. This 4.5x difference may affect circuit performance in high-impedance applications where input bias current contributes to offset errors. Applications with input impedances below 1 MΩ are generally unaffected. Verify input bias current requirements for your specific application before substitution.
Q: Are all substitute parts RoHS3 compliant?
A: Yes, all substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. All parts are also classified under ECCN EAR99 and HTSUS 8542.33.0001, maintaining consistent regulatory classification with the original BA2902FV-E2.
Q: What packaging formats are available for substitute parts?
A: Substitute parts are available in three packaging formats: Cut Tape (CT) & Digi-Reel® (matching the original BA2902FV-E2 format), Tape & Reel (TR) for alternative supply methods, and Tube packaging for some obsolete variants. Select packaging format based on manufacturing process requirements and inventory management practices.
