Engineering Selection Recommendations

The BA178M07FP-E2 is the direct active equivalent for the obsolete BA78M07FP-E2. Selection of the BA178M07FP-E2 is supported by:

• Identical electrical specifications across all critical parameters (output voltage, output current, input voltage range, dropout voltage, PSRR)
• Identical package footprint and pinout (TO-252-3, DPAK)
• Identical operating temperature range (-40°C ~ 85°C)
• Active product status ensuring long-term availability
• ROHS3 compliance and REACH unaffected status maintained
• Same manufacturer (Rohm Semiconductor) ensuring design continuity

The substitute part is suitable for direct PCB replacement without circuit modification or re-qualification when the original part number is no longer available.

Frequently Asked Questions (FAQ)

Q: Can BA178M07FP-E2 be used as a direct replacement for BA78M07FP-E2?

A: Yes. Both parts share identical electrical specifications for output voltage (7V), output current (500mA), input voltage range (22V max), dropout voltage (2V @ 500mA), and operating temperature range (-40°C ~ 85°C). The package footprint and pinout are identical (TO-252-3, DPAK).

Q: What is the difference between the two part numbers?

A: The BA178M07FP-E2 is the active production equivalent of the obsolete BA78M07FP-E2. Both are manufactured by Rohm Semiconductor with identical electrical and mechanical specifications. The primary difference is product status: BA78M07FP-E2 is obsolete while BA178M07FP-E2 is active.

Q: Are there differences in quiescent current between these parts?

A: The BA178M07FP-E2 specifies a quiescent current (Iq) of 4.5 mA compared to 6 mA for the BA78M07FP-E2. This represents improved power efficiency in the substitute part and does not affect functional compatibility.

Q: Do both parts have the same package footprint?

A: Yes. Both the BA78M07FP-E2 and BA178M07FP-E2 use the TO-252-3 package (DPAK with 2 Leads + Tab, SC-63 designation). PCB layout and footprint remain unchanged.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) and Tape & Reel (TR) are supply formats only. The BA78M07FP-E2 is supplied in Cut Tape format while BA178M07FP-E2 is supplied in Tape & Reel format. Both formats contain identical components; the difference is in packaging and handling for production environments.

Q: Are both parts RoHS compliant?

A: Yes. Both BA78M07FP-E2 and BA178M07FP-E2 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.
