BA178M07T Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The BA178M07T is an active linear voltage regulator IC manufactured by Rohm Semiconductor, classified as a Power Management (PMIC) component. This positive fixed output regulator delivers 500mA at 7V output with a maximum input voltage of 22V and is packaged in TO-220-3 Full Pack configuration for through-hole mounting applications. The part is actively produced and ROHS3 compliant, making it suitable for industrial and commercial power supply designs requiring regulated 7V output at moderate current levels. Alternative models may be required when application specifications demand higher output current capacity, extended operating temperature ranges, or enhanced protection features.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA178M07T is determined by the following critical parameters that must remain compatible:

• Output Voltage (Fixed): Must be 7V to maintain circuit voltage requirements
• Package / Case: Must be TO-220-3 Full Pack to ensure mechanical and thermal compatibility with existing PCB layouts
• Mounting Type: Must be Through Hole to match board assembly specifications
• Output Configuration: Must be Positive to maintain polarity requirements
• Output Type: Must be Fixed to ensure stable regulated output

The BA07CC0T qualifies as a substitute because it maintains identical output voltage (7V), identical package configuration (TO-220-3 Full Pack), identical mounting type (Through Hole), and identical output configuration and type. The BA07CC0T provides enhanced specifications including higher output current capacity (1A versus 500mA), lower quiescent current (2.5 mA versus 4.5 mA), extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), and integrated protection features (Over Current, Over Temperature, Over Voltage).

Parameter Comparison

Engineering Selection Recommendations

Both the BA178M07T and BA07CC0T are active products from Rohm Semiconductor with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The BA178M07T is appropriate for applications with current requirements not exceeding 500mA and operating temperatures within -40°C to 85°C, where the higher PSRR specification (71dB) provides superior power supply rejection ratio performance.

The BA07CC0T is appropriate for applications requiring higher output current capacity (up to 1A), extended operating temperature range (-40°C to 125°C), or integrated protection against overcurrent, overtemperature, and overvoltage conditions. The lower quiescent current (2.5 mA) makes it suitable for battery-powered or low-power standby applications.

Both parts maintain identical mechanical compatibility through TO-220-3 Full Pack packaging and through-hole mounting, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can BA07CC0T directly replace BA178M07T in existing designs?

A: Yes. Both parts share identical output voltage (7V), package configuration (TO-220-3 Full Pack), and mounting type (Through Hole). The BA07CC0T provides higher current capacity (1A versus 500mA) and integrated protection features, making it a functionally superior substitute. No PCB modifications are required.

Q: What are the key differences between these two regulators?

A: The primary differences are output current rating (BA178M07T: 500mA; BA07CC0T: 1A), operating temperature range (BA178M07T: -40°C ~ 85°C; BA07CC0T: -40°C ~ 125°C), quiescent current (BA178M07T: 4.5 mA; BA07CC0T: 2.5 mA), PSRR performance (BA178M07T: 71dB; BA07CC0T: 55dB), and protection features (BA07CC0T includes Over Current, Over Temperature, and Over Voltage protection).

Q: Are there any thermal or mechanical considerations when substituting?

A: Both parts use identical TO-220-3 Full Pack packaging with through-hole mounting. Thermal management requirements depend on application current draw and ambient temperature. The BA07CC0T's higher current rating (1A) may require thermal analysis if operating near maximum specifications in high-temperature environments.

Q: Do both parts meet current compliance standards?

A: Yes. Both BA178M07T and BA07CC0T are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial electronics manufacturing.

Q: Which part should be selected for new designs?

A: For new designs, the BA07CC0T is recommended due to its active product status, extended operating temperature range, integrated protection features, and lower quiescent current consumption, provided the application does not require the superior PSRR performance of the BA178M07T.
