BA08SFP-E2 Equivalent & Substitute Parts

Part Overview

The BA08SFP-E2 is a linear voltage regulator IC from Rohm Semiconductor, classified as a Power Management (PMIC) device. It delivers a fixed 8V positive output at 1A maximum current in a TO-252-5 surface mount package. The device is marked as "Not For New Designs," indicating it has been superseded in Rohm's product portfolio. Finding equivalent and substitute parts is necessary for applications requiring continued supply, design updates, or inventory optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA08SFP-E2 is determined by the following critical parameters:

• Output Voltage: Must be fixed at 8V
• Output Configuration: Must be positive
• Package Type: Must be TO-252-5 (DPAK, 4 Leads + Tab)
• Mounting Type: Must be surface mount
• Output Current: Must support minimum 1A (equal or greater)
• Input Voltage Range: Must accommodate maximum 25V input
• Protection Features: Must include over current, over temperature, and over voltage protection
• Compliance: Must maintain ROHS3 compliance

Two substitute parts meet these criteria: BA08CC0WFP-E2 (direct Rohm equivalent) and TL751M08QKVURQ1 (Texas Instruments alternative). Both maintain identical output specifications, package compatibility, and protection feature sets while offering improved product status or enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

BA08CC0WFP-E2 is the primary direct substitute. It is manufactured by Rohm Semiconductor with identical electrical specifications and package compatibility. The part carries Active product status, ensuring long-term availability and supply chain stability. Operating temperature range extends to 125°C compared to the original 85°C maximum, providing enhanced thermal margin. This part is recommended for applications requiring continuity with the original design while benefiting from improved lifecycle status.

TL751M08QKVURQ1 is a cross-manufacturer alternative from Texas Instruments. It maintains 8V fixed output, TO-252-5 package compatibility, and identical PSRR performance. The output current specification is 750mA, which is lower than the original 1A rating; this part is suitable only for applications with maximum current requirements not exceeding 750mA. The device includes reverse polarity protection as an additional feature and carries AEC-Q100 automotive qualification. Operating temperature range extends to 125°C. This part is recommended for automotive-grade applications or designs where 750mA output current is sufficient.

Frequently Asked Questions (FAQ)

Q: Can BA08CC0WFP-E2 be used as a direct drop-in replacement for BA08SFP-E2?

A: Yes. Both parts share identical output voltage (8V), output current (1A), input voltage rating (25V), package type (TO-252-5), and protection features. The BA08CC0WFP-E2 has an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C), which is a performance enhancement. Pin configuration and PCB footprint are identical.

Q: What is the key limitation of TL751M08QKVURQ1 as a substitute?

A: The output current rating is 750mA, compared to 1A for the BA08SFP-E2. This part is suitable only for applications where the maximum required output current does not exceed 750mA. If your design requires the full 1A output capability, TL751M08QKVURQ1 is not appropriate.

Q: Are all three parts in the same package?

A: Yes. All three parts use the TO-252-5 package (DPAK with 4 leads plus tab), ensuring identical PCB footprint and mounting compatibility.

Q: Why is BA08SFP-E2 marked "Not For New Designs"?

A: This designation indicates the part has been superseded in Rohm's product portfolio. BA08CC0WFP-E2 is the active replacement. For new designs, BA08CC0WFP-E2 is the recommended choice.

Q: Does TL751M08QKVURQ1 include additional protection compared to the original part?

A: Yes. TL751M08QKVURQ1 includes reverse polarity protection in addition to over current, over temperature, and over voltage protection. The original BA08SFP-E2 does not specify reverse polarity protection.

Q: What is the difference in operating temperature range?

A: BA08SFP-E2 operates from -40°C to 85°C. Both BA08CC0WFP-E2 and TL751M08QKVURQ1 operate from -40°C to 125°C, providing a 40°C higher maximum temperature rating. This is beneficial for applications in elevated ambient conditions or high-power dissipation environments.

Q: Is AEC-Q100 qualification relevant for my application?

A: AEC-Q100 qualification applies to automotive-grade components. If your application is automotive or requires automotive-grade reliability standards, TL751M08QKVURQ1 meets this requirement. For non-automotive applications, this qualification is not a selection criterion.
