MC7806ACT Equivalent & Substitute Parts

Part Overview

The MC7806ACT is a linear voltage regulator IC from onsemi, designed to provide a fixed positive 6V output at 1A current capacity in a TO-220-3 package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Linear voltage regulators in this category are fundamental power management components used in applications requiring stable DC voltage conversion from higher input voltages. The MC7806ACT series operates across a wide input voltage range up to 35V and includes integrated over-temperature and short-circuit protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MC7806ACT is determined by strict alignment of electrical and mechanical parameters:

Direct Equivalents maintain identical output voltage (6V), output current rating (1A minimum), input voltage tolerance (35V max), dropout voltage characteristics, quiescent current, PSRR, and TO-220-3 package configuration. These parts are pin-compatible and functionally interchangeable without circuit modification.

Similar Substitutes share the same output voltage (6V), input voltage rating (35V max), dropout voltage, quiescent current, PSRR, and package type, but may have higher output current ratings (1.5A or greater). These parts are backward-compatible in applications where the original 1A rating is sufficient, as higher-rated regulators can supply equal or lesser current without performance degradation.

Substitution eligibility is restricted to parts meeting all of the following criteria:

• Output voltage: 6V fixed
• Input voltage maximum: 35V
• Package / Case: TO-220-3
• Mounting type: Through Hole
• Protection features: Over Temperature and Short Circuit

Parameter Comparison

Engineering Selection Recommendations

MC7806ACTG is the direct equivalent from onsemi. This part maintains identical electrical specifications and TO-220-3 package configuration as the MC7806ACT. The primary distinction is RoHS3 compliance status, making MC7806ACTG suitable for applications with regulatory compliance requirements. Both parts are classified as obsolete.

L7806ABV from STMicroelectronics is a similar substitute with higher output current capacity (1.5A versus 1A). This part meets all core electrical and mechanical substitution criteria and provides an extended operating temperature range (-40°C to 125°C versus 0°C to 125°C). L7806ABV is RoHS3 compliant and suitable for applications requiring broader temperature operation or higher current headroom. The higher current rating does not create incompatibility in circuits designed for 1A operation.

Selection between MC7806ACTG and L7806ABV depends on regulatory compliance requirements and temperature range specifications of the target application. Both parts are functionally equivalent for standard 6V, 1A regulator applications in TO-220 packages.

Frequently Asked Questions (FAQ)

Q: Can MC7806ACTG be used as a direct replacement for MC7806ACT?

A: Yes. MC7806ACTG is electrically and mechanically identical to MC7806ACT, with the same 6V output, 1A current rating, TO-220-3 package, and protection features. The primary difference is RoHS3 compliance status.

Q: Is L7806ABV compatible with circuits designed for MC7806ACT?

A: Yes. L7806ABV shares the same output voltage (6V), input voltage rating (35V max), dropout voltage, quiescent current, PSRR, and TO-220-3 package. The higher output current rating (1.5A) does not create incompatibility; the regulator will operate correctly in applications requiring 1A or less.

Q: What is the significance of the extended temperature range in L7806ABV?

A: L7806ABV operates from -40°C to 125°C, compared to 0°C to 125°C for MC7806ACT. This extended lower temperature limit is relevant only for applications requiring operation below 0°C. For standard room-temperature and elevated-temperature applications, both parts perform identically.

Q: Are all three parts pin-compatible?

A: Yes. All three parts (MC7806ACT, MC7806ACTG, and L7806ABV) use the TO-220-3 package with identical pin configuration, allowing direct PCB substitution without layout modification.

Q: Why is RoHS compliance status different between these parts?

A: MC7806ACT predates RoHS3 regulations and is marked as non-compliant. MC7806ACTG and L7806ABV are manufactured to meet ROHS3 compliance standards, making them suitable for applications with regulatory requirements or procurement policies mandating RoHS compliance.
