BA17807T Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The BA17807T is a linear voltage regulator IC manufactured by Rohm Semiconductor, designed for positive fixed 7V output applications with 1A current capacity in a TO-220-3 Full Pack configuration. This device operates across an input voltage range up to 22V with a maximum dropout voltage of 2V at 1A typical operation.

The BA17807T carries a "Not For New Designs" product status, indicating it is a legacy component. Organizations requiring this functionality for new or ongoing production must evaluate qualified substitute parts that meet equivalent electrical and mechanical specifications while offering active product support and enhanced operational characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA17807T is determined by the following critical parameters:

• Output Voltage Configuration: Fixed 7V positive output (non-negotiable)
• Output Current Rating: Minimum 1A capacity
• Package/Mounting: TO-220-3 Full Pack, Through Hole configuration
• Input Voltage Tolerance: Maximum input voltage of 22V or greater
• Operating Temperature Range: Support for -40°C minimum and 85°C minimum upper limit
• Electrical Characteristics: Dropout voltage, quiescent current, and PSRR performance within acceptable operational margins

The BA07CC0T qualifies as a direct substitute based on matching output voltage (7V), output current (1A), package configuration (TO-220-3 Full Pack), and mounting type (Through Hole). The substitute demonstrates enhanced specifications in several parameters while maintaining full compatibility with existing circuit designs.

Engineering Selection Recommendations

The BA07CC0T is qualified as a direct substitute for the BA17807T based on electrical and mechanical parameter equivalence. Selection between these parts should consider the following factors:

Product Status: The BA07CC0T carries "Active" product status, ensuring ongoing manufacturer support, availability, and compliance updates. The BA17807T "Not For New Designs" designation indicates end-of-life status and potential supply constraints.

Compliance & Certifications: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Protection Features: The BA07CC0T integrates Over Current, Over Temperature, and Over Voltage protection mechanisms, providing enhanced circuit reliability compared to the BA17807T, which specifies no protection features.

Operating Temperature Range: The BA07CC0T supports extended operation to 125°C, compared to the BA17807T maximum of 85°C, offering greater thermal margin in applications subject to elevated ambient conditions.

Quiescent Current Performance: The BA07CC0T demonstrates 2.5 mA quiescent current versus 4.5 mA for the BA17807T, reducing standby power consumption in battery-powered or low-power applications.

Frequently Asked Questions (FAQ)

Q: Can BA07CC0T replace BA17807T in existing circuit designs?

A: Yes. Both devices provide identical 7V fixed output voltage, 1A output current capacity, and TO-220-3 Full Pack through-hole mounting. Pin configuration and electrical interface are compatible. Existing PCB layouts and circuit designs require no modification.

Q: What are the key differences between these parts?

A: The BA07CC0T offers three primary advantages: (1) Active product status with ongoing manufacturer support versus legacy "Not For New Designs" status; (2) Integrated protection features (Over Current, Over Temperature, Over Voltage) versus none specified on BA17807T; (3) Extended operating temperature range to 125°C versus 85°C maximum. The BA07CC0T also demonstrates lower quiescent current (2.5 mA vs 4.5 mA) and supports higher maximum input voltage (25V vs 22V).

Q: Are there any performance trade-offs when substituting BA07CC0T for BA17807T?

A: The BA17807T provides higher Power Supply Rejection Ratio (PSRR) at 69dB compared to BA07CC0T at 55dB (120Hz). Applications requiring maximum noise rejection may require circuit evaluation. All other electrical parameters remain equivalent or improved with the substitute part.

Q: What packaging differences exist between these parts?

A: Both parts use identical TO-220-3 Full Pack configuration with through-hole mounting. The primary packaging difference is supplier delivery format: BA17807T is supplied in Bulk packaging, while BA07CC0T is supplied in Tube packaging. This does not affect circuit compatibility or performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both BA17807T and BA07CC0T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component use in regulated markets.
