BA78M06CP-E2 Equivalent & Substitute Parts

Part Overview

The BA78M06CP-E2 is a linear voltage regulator IC from Rohm Semiconductor designed for positive fixed 6V output applications with 500mA current capacity in a TO-220-3 cropped leads package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The BA78M06CP-E2 provides regulated 6V output with integrated over-current and over-temperature protection, suitable for applications requiring stable low-voltage power distribution in through-hole mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA78M06CP-E2 is determined by the following critical parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Output voltage: 6V fixed
• Package type: TO-220-3 cropped leads
• Mounting type: Through hole
• Output configuration: Positive
• Protection features: Over current and over temperature protection

Flexible Parameters (May Vary Within Limits):

• Current output capacity: May be equal to or greater than 500mA
• Input voltage maximum: Must accommodate 21V or higher
• Quiescent current: Minor variations acceptable
• PSRR: Minor variations acceptable

The BA7806CP-E2 qualifies as a direct substitute because it maintains identical output voltage (6V), identical package configuration (TO-220-3 cropped leads), identical input voltage rating (21V max), identical protection features, and identical operating temperature range. The primary difference is increased current output capacity (1A versus 500mA), which represents an enhancement rather than a limitation for the BA78M06CP-E2 application space.

Engineering Selection Recommendations

The BA7806CP-E2 is the qualified substitute for the obsolete BA78M06CP-E2. Selection is based on the following engineering criteria:

Compliance & Regulatory Status: Both parts maintain ROHS3 compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001), ensuring no change in supply chain or export documentation requirements.

Product Availability: The BA7806CP-E2 carries active product status with 3160 units in stock, compared to the obsolete BA78M06CP-E2 with limited remaining inventory of 1030 units. This availability differential supports long-term production continuity.

Electrical Compatibility: The BA7806CP-E2 maintains identical output voltage regulation (6V), identical maximum input voltage (21V), identical dropout voltage specification (2V typical), and identical protection architecture. The increased current output capacity (1A versus 500mA) provides design margin without introducing incompatibility.

Thermal & Environmental Consistency: Operating temperature range remains -40°C to 85°C across both parts, ensuring thermal performance equivalence in target applications.

Package & Mechanical Compatibility: Both parts use identical TO-220-3 cropped leads packaging with through-hole mounting, requiring no PCB redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can BA7806CP-E2 directly replace BA78M06CP-E2 without circuit modification?

A: Yes. The BA7806CP-E2 maintains identical output voltage (6V), input voltage rating (21V max), package configuration (TO-220-3 cropped leads), and protection features. No circuit modification is required. The increased current capacity (1A versus 500mA) represents a design enhancement.

Q: What is the primary difference between these two parts?

A: The BA7806CP-E2 provides 1A output current capacity compared to the BA78M06CP-E2's 500mA capacity. All other electrical and mechanical specifications remain equivalent. The BA7806CP-E2 also carries active product status versus obsolete status for the BA78M06CP-E2.

Q: Are there any thermal or reliability differences?

A: Both parts operate across the identical temperature range (-40°C to 85°C) and include identical protection features (over-current and over-temperature). The quiescent current differs slightly (8mA versus 6mA), and PSRR differs marginally (73dB versus 74dB at 120Hz), but these variations do not affect functional equivalence in standard 6V regulator applications.

Q: Is PCB layout modification necessary when substituting BA7806CP-E2 for BA78M06CP-E2?

A: No. Both parts use identical TO-220-3 cropped leads packaging with through-hole mounting. Pin configuration and mechanical footprint are identical, requiring no PCB layout changes.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. No change in regulatory documentation or supply chain procedures is required.

Q: Why is BA78M06CP-E2 classified as obsolete?

A: The BA78M06CP-E2 has reached end-of-life status with Rohm Semiconductor. The BA7806CP-E2 represents the active product continuation with enhanced current capacity and ongoing manufacturing support.
