BA10FP-E2 Equivalent & Substitute Parts

Part Overview

The BA10FP-E2 is a linear voltage regulator IC from Rohm Semiconductor designed for positive fixed 10V output at 1A current capacity in a TO-252-3 surface mount package. This device is classified as Not For New Designs, indicating it has reached end-of-life status. Finding equivalent substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original component is no longer readily available or where design flexibility permits alternative sources.

Substitute Part Grouping Explanation

Substitute parts for the BA10FP-E2 are selected based on the following critical parameters that determine functional compatibility:

Fixed output voltage of 10V
Surface mount TO-252-3 package compatibility
Positive output configuration
Over current and over temperature protection
ROHS3 compliance
Output current capacity at or above the application requirement

The two identified substitutes meet these core criteria while offering active product status and improved availability. Output current ratings differ from the original 1A specification; applications must verify that the substitute's current rating meets or exceeds the circuit requirement.

Engineering Selection Recommendations

Both substitute parts are active products from Texas Instruments with ROHS3 compliance, providing superior availability compared to the BA10FP-E2.

TL750M10CKVURG3 is the primary substitute candidate. It maintains the 10V fixed output voltage, operates at 750mA output current, and includes reverse polarity protection. The maximum input voltage of 26V exceeds the original 25V specification. This part is suitable for applications where the 750mA current rating meets or exceeds the circuit requirement.

UA78M10CKVURG3 is a secondary substitute option. It provides the same 10V fixed output voltage with 500mA output current capacity and the highest PSRR rating (80dB) among the three parts. The maximum input voltage of 28V provides additional margin. This part is suitable only for applications requiring 500mA or less output current.

Both substitutes operate across the 0°C to 125°C temperature range, which is wider than the original -40°C to 85°C range. Applications requiring the original lower temperature limit must confirm compatibility with the substitute's minimum operating temperature.

Frequently Asked Questions (FAQ)

Q: Can TL750M10CKVURG3 directly replace BA10FP-E2 in all applications?

A: Direct replacement is possible only if the application's maximum output current requirement does not exceed 750mA. The 750mA rating is lower than the original 1A specification. Verify the circuit's actual current draw before substitution.

Q: What is the difference between the two substitute parts?

A: TL750M10CKVURG3 provides 750mA output current with 0.6V dropout voltage. UA78M10CKVURG3 provides 500mA output current with 2V dropout voltage but offers superior PSRR performance at 80dB. Select based on the application's current and noise rejection requirements.

Q: Are the substitute parts pin-compatible with BA10FP-E2?

A: All three parts use the TO-252-3 DPAK package with identical pinout configuration (2 leads plus tab). Physical and electrical pin compatibility is confirmed.

Q: What is the impact of the different operating temperature ranges?

A: BA10FP-E2 operates from -40°C to 85°C. Both substitutes operate from 0°C to 125°C. Applications requiring operation below 0°C cannot use the substitute parts. Applications within the 0°C to 85°C range are compatible with both substitutes.

Q: Do the substitute parts include the same protection features?

A: All three parts include over current and over temperature protection. TL750M10CKVURG3 adds reverse polarity protection. UA78M10CKVURG3 includes short circuit protection. The BA10FP-E2 includes over voltage protection, which is not explicitly listed for the substitutes.

Q: What is the Moisture Sensitivity Level difference?

A: BA10FP-E2 has MSL 1 (unlimited shelf life). Both substitutes have MSL 3 (168 hours at 60% relative humidity and 30°C). This affects storage and handling requirements for the substitute parts.
