Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SA06830R is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor type must be PNP
• Maximum collector current must be greater than or equal to 1 A
• Collector-emitter breakdown voltage must be greater than or equal to 25 V
• Maximum power dissipation must be greater than or equal to 1 W
• Transition frequency must support the intended application frequency range

Mechanical Compatibility Criteria:

• Mounting type must be through-hole
• Package must be physically compatible with TO-92 form factor or equivalent E-Line configuration

The ZTX549 manufactured by Diodes Incorporated meets these substitution criteria. It is a PNP transistor with 1 A maximum collector current, 30 V collector-emitter breakdown voltage, 1 W power rating, and through-hole E-Line packaging compatible with TO-92 footprints.

Parameter Comparison

Engineering Selection Recommendations

The ZTX549 is a suitable substitute for the 2SA06830R based on the following factors:

Electrical Performance: The ZTX549 exceeds the electrical specifications of the 2SA06830R. It provides a higher collector-emitter breakdown voltage (30 V versus 25 V), supporting operation in circuits designed for the original part. The maximum collector current (1 A) and power dissipation (1 W) are identical. The transition frequency of the ZTX549 (100 MHz) is lower than the 2SA06830R (200 MHz); this difference is acceptable for applications not requiring the higher frequency performance of the original part.

Mechanical Compatibility: The ZTX549 is packaged in an E-Line configuration that is physically compatible with TO-92 footprints, enabling direct board-level substitution without layout modifications.

Product Status and Compliance: The ZTX549 is an active product with current manufacturing support and availability. It is ROHS3 compliant, meeting modern regulatory requirements. The 2SA06830R is obsolete and non-compliant with current environmental standards.

Thermal Performance: The ZTX549 supports a maximum operating temperature of 200°C, exceeding the 2SA06830R specification of 150°C, providing additional thermal margin in applications with elevated ambient conditions.

Frequently Asked Questions (FAQ)

Q: Can the ZTX549 be used as a direct replacement for the 2SA06830R in existing circuit designs?

A: Yes. The ZTX549 meets or exceeds all critical electrical parameters of the 2SA06830R. The E-Line package is physically compatible with TO-92 through-hole footprints, enabling direct substitution without circuit board modifications.

Q: What is the significance of the difference in transition frequency between the two parts?

A: The 2SA06830R has a transition frequency of 200 MHz, while the ZTX549 has 100 MHz. For applications operating below 100 MHz, this difference is not significant. For circuits requiring operation above 100 MHz, the frequency limitation of the ZTX549 must be evaluated against the specific application requirements.

Q: Are there differences in saturation voltage characteristics between these parts?

A: Yes. The 2SA06830R specifies a maximum saturation voltage of 400 mV at 50 mA base current and 500 mA collector current. The ZTX549 specifies 750 mV at 200 mA base current and 2 A collector current. These measurements are taken at different operating points and cannot be directly compared. Circuit designs should be evaluated based on the specific bias conditions used in the application.

Q: What is the difference in DC current gain between the two transistors?

A: The 2SA06830R specifies a minimum DC current gain (hFE) of 120 at 500 mA collector current and 10 V collector-emitter voltage. The ZTX549 specifies a minimum hFE of 100 at 500 mA collector current and 2 V collector-emitter voltage. Both parts provide sufficient current gain for typical switching applications. Circuit designs relying on specific gain values should account for the measurement conditions and part-to-part variation.

Q: Is the ZTX549 available in the same packaging as the 2SA06830R?

A: The 2SA06830R uses a TO-92L-A1 package (long body TO-92). The ZTX549 uses an E-Line package, which is physically compatible with standard TO-92 footprints. Both are three-lead through-hole packages suitable for insertion into PCB holes with 0.1-inch lead spacing.

Q: What is the compliance status of each part?

A: The 2SA06830R is RoHS non-compliant and obsolete. The ZTX549 is ROHS3 compliant and an active product with current manufacturing support. For new designs or systems requiring regulatory compliance, the ZTX549 is the appropriate selection.
