BA07T Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The BA07T is a linear voltage regulator IC manufactured by Rohm Semiconductor, designed for positive fixed output regulation at 7V with 1A output current capacity. This Through Hole mounted device in TO-220-3 Full Pack configuration is actively produced and suitable for new designs. Finding equivalent and substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements where alternative electrical or mechanical parameters are acceptable within system tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA07T is determined by the following critical parameters that must remain consistent or within acceptable tolerances:

• Output Voltage (Fixed): Must be 7V to maintain circuit voltage requirements
• Output Current Capacity: Must be 1A or greater to support load specifications
• Package / Case: Must be TO-220-3 Full Pack to ensure mechanical and thermal compatibility
• Mounting Type: Must be Through Hole for PCB assembly compatibility
• Operating Temperature Range: Must support -40°C ~ 85°C minimum
• Output Configuration: Must be Positive Fixed output type
• Number of Regulators: Must be single regulator (1 output)

The BA17807T qualifies as a substitute part based on these criteria. While certain electrical parameters differ (Input Voltage Max: 22V vs 25V; Quiescent Current: 4.5mA vs 2.5mA), these variations remain within acceptable substitution tolerances for the specified output voltage and current ratings.

Engineering Selection Recommendations

The BA07T is the preferred choice for new designs due to its Active product status and full compliance with current manufacturing standards. The BA17807T is electrically compatible as a substitute part, meeting the core functional requirements of 7V fixed output at 1A current capacity with identical package and mounting specifications. However, the BA17807T carries a "Not For New Designs" status, indicating it is in end-of-life phase.

Selection between these parts should be based on:

• New Designs: Specify BA07T to ensure long-term availability and manufacturer support
• Existing Inventory or Legacy Systems: BA17807T remains functionally compatible provided the reduced maximum input voltage (22V vs 25V) and increased quiescent current (4.5mA vs 2.5mA) are acceptable within system design margins
• Compliance Requirements: Both parts are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements

Frequently Asked Questions (FAQ)

Q: Can BA17807T be used as a direct replacement for BA07T in new designs?

A: While BA17807T is electrically compatible, it is designated "Not For New Designs" by the manufacturer. New designs should specify BA07T to ensure supply continuity and manufacturer support throughout the product lifecycle.

Q: What is the impact of the 3V difference in maximum input voltage (25V vs 22V)?

A: The BA07T supports input voltages up to 25V, while BA17807T supports up to 22V. If your application requires input voltages between 22V and 25V, BA07T must be used. For applications with maximum input voltage at or below 22V, BA17807T is acceptable.

Q: Are the package and mounting specifications identical?

A: Yes. Both BA07T and BA17807T use TO-220-3 Full Pack configuration with Through Hole mounting. They are mechanically and thermally interchangeable from a PCB assembly perspective.

Q: Does the higher quiescent current of BA17807T affect circuit performance?

A: BA17807T has a quiescent current of 4.5mA compared to BA07T's 2.5mA. This 2mA difference may impact power consumption in battery-powered or low-power applications. Verify that your system power budget accommodates this increase.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both BA07T and BA17807T are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What does "Not For New Designs" mean for BA17807T?

A: This designation indicates the part is in end-of-life phase. While existing inventory may be available, the manufacturer does not recommend its use in new product designs. Existing stock may be used for legacy system support or repairs.
