Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BA09CC0FP-E2 are qualified based on the following critical parameters:

• Fixed output voltage of 9V
• Surface Mount TO-252-3 package compatibility
• Maximum input voltage rating of 25V or greater
• Protection features including Over Current and Over Temperature
• Active product status with current manufacturing availability
• ROHS3 compliance

The UA78M09CKVURG3 from Texas Instruments meets these substitution criteria. While the output current rating differs (500mA versus 1A), this part qualifies as a substitute in applications where the lower current capacity is acceptable within the circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the BA09CC0FP-E2 and UA78M09CKVURG3 are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current production designs. Selection between these parts depends on output current requirements: the BA09CC0FP-E2 supports 1A output, while the UA78M09CKVURG3 is rated for 500mA maximum output. The UA78M09CKVURG3 offers superior PSRR performance (80dB versus 55dB at 120Hz) and a slightly higher maximum input voltage rating (26V versus 25V). Operating temperature range differs, with the BA09CC0FP-E2 supporting extended low-temperature operation (-40°C minimum versus 0°C minimum).

Frequently Asked Questions (FAQ)

Q: Can the UA78M09CKVURG3 directly replace the BA09CC0FP-E2 in all applications?

A: Direct substitution is possible only in applications where the circuit load current does not exceed 500mA. The UA78M09CKVURG3 is rated for 500mA maximum output current, compared to the BA09CC0FP-E2 at 1A. Verify circuit current requirements before substitution.

Q: Are the packages mechanically identical?

A: Both parts use the TO-252-3 DPAK package with 2 leads plus tab configuration. PCB footprints are compatible for direct substitution without layout modification.

Q: What is the difference in dropout voltage between these parts?

A: The BA09CC0FP-E2 does not specify maximum dropout voltage in the provided data. The UA78M09CKVURG3 specifies 2V dropout at 350mA output current.

Q: Do both parts include thermal protection?

A: Yes, both the BA09CC0FP-E2 and UA78M09CKVURG3 include Over Temperature protection as part of their integrated protection feature set.

Q: Which part has better noise performance?

A: The UA78M09CKVURG3 provides superior Power Supply Rejection Ratio (PSRR) at 80dB (120Hz) compared to the BA09CC0FP-E2 at 55dB (120Hz), resulting in better rejection of input voltage ripple and noise.

Q: Are there temperature range considerations for substitution?

A: The BA09CC0FP-E2 operates from -40°C to 125°C, while the UA78M09CKVURG3 operates from 0°C to 125°C. Applications requiring operation below 0°C must use the BA09CC0FP-E2.
