Engineering Selection Recommendations

BA7809FP-E2 maintains full electrical and mechanical compatibility with BA09FP-E2. Both devices are manufactured by Rohm Semiconductor, share identical output specifications (9V, 1A), operate across the same temperature range (-40°C ~ 85°C), and are housed in the same TO-252-3 package. Both are Active status products with ROHS3 compliance.

UA78M09CKVURG3 (Texas Instruments) provides an alternative with identical 9V output and TO-252-3 packaging. This device is suitable for applications where output current requirements do not exceed 500mA. The extended operating temperature range (0°C ~ 125°C) and higher PSRR (80dB) may benefit specific system designs. Active product status and ROHS3 compliance are maintained.

Selection between these substitutes depends on output current requirements and operating temperature specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can BA7809FP-E2 directly replace BA09FP-E2 in existing designs?

A: Yes. Both parts deliver 9V fixed output at 1A maximum current, operate across -40°C to 85°C, and use identical TO-252-3 (DPAK) packaging. PCB layout and schematic connections remain unchanged.

Q: Is UA78M09CKVURG3 suitable for all BA09FP-E2 applications?

A: UA78M09CKVURG3 is suitable only for applications where maximum output current does not exceed 500mA. If your circuit requires the full 1A output capability of BA09FP-E2, this substitute is not appropriate.

Q: What are the package compatibility requirements?

A: All three parts use TO-252-3 (DPAK) packaging with 2 Leads + Tab configuration (SC-63). This ensures mechanical and thermal compatibility on existing PCBs without layout modifications.

Q: Are all substitutes RoHS compliant?

A: Yes. BA09FP-E2, BA7809FP-E2, and UA78M09CKVURG3 are all ROHS3 compliant, meeting regulatory requirements for electronic component manufacturing and assembly.

Q: What protection features are included in each part?

A: BA09FP-E2 includes Over Current, Over Temperature, and Over Voltage protection. BA7809FP-E2 includes Over Current and Over Temperature protection. UA78M09CKVURG3 includes Over Current, Over Temperature, and Short Circuit protection.
