TIP30C Equivalent & Substitute Parts

Part Overview

The TIP30C is a PNP bipolar junction transistor manufactured by onsemi, rated for 100 V collector-emitter breakdown voltage and 1 A maximum collector current in a TO-220-3 through-hole package. This device is classified as obsolete, indicating that direct replacement with active production alternatives is necessary for new designs and ongoing procurement. The TIP30C remains functionally available in inventory but requires evaluation of equivalent parts that maintain active product status and compliance with current regulatory standards.

Substitute Part Grouping Explanation

Substitution of the TIP30C is determined by matching the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

Transistor Type: PNP
Voltage - Collector Emitter Breakdown (Max): 100 V
Mounting Type: Through Hole
Package / Case: TO-220-3

Flexible Parameters (Application-Dependent):

Current - Collector (Ic) (Max): Substitute parts may exceed the 1 A specification if the application permits higher current capability
Power - Max: Substitute parts may exceed the 2 W specification if thermal management is adequate
Frequency - Transition: Substitute parts may differ if frequency response requirements are not critical
Operating Temperature: Substitute parts with extended temperature ranges provide additional design margin

Substitute parts are grouped into two categories: Direct Equivalents (matching all electrical specifications within tolerance) and Higher-Capacity Alternatives (exceeding current or power ratings while maintaining voltage and package compatibility).

Engineering Selection Recommendations

TIP30CG (Direct Equivalent)

The TIP30CG is the primary substitute for the TIP30C. Both parts share identical electrical specifications: 100 V breakdown voltage, 1 A maximum collector current, 2 W power dissipation, and 3 MHz transition frequency. The TIP30CG maintains active product status and is RoHS3 compliant, addressing the obsolescence of the original TIP30C. Packaging differs only in supplier designation (Tube vs. unspecified for TIP30C), with both using the TO-220-3 case. This part is the recommended choice for direct replacement in existing designs.

TIP32CG (Higher-Current Alternative)

The TIP32CG provides 3 A maximum collector current while maintaining the 100 V voltage rating and TO-220-3 package. Power dissipation remains at 2 W. This part is suitable for applications requiring increased current capacity beyond the 1 A specification of the TIP30C. RoHS3 compliance and active product status make this a viable long-term alternative. Selection of this part requires verification that the application circuit can tolerate the higher current capability without adverse effects.

TIP42CG (Higher-Current Alternative)

The TIP42CG provides 6 A maximum collector current at 100 V breakdown voltage in the TO-220-3 package. Power dissipation is 2 W. This part is appropriate for applications with significantly higher current demands. RoHS3 compliance and active product status support its use in new designs. Circuit verification is required to ensure compatibility with the increased current rating.

KSA1010YTU (Higher-Current Alternative)

The KSA1010YTU provides 7 A maximum collector current at 100 V breakdown voltage in the TO-220-3 package. Power dissipation is rated at 1.5 W, which is lower than the TIP30C. Transition frequency is not specified. RoHS3 compliance and active product status are confirmed. This part is suitable for high-current applications but requires thermal design consideration due to the lower power rating.

BD912 (High-Power Alternative)

The BD912, manufactured by NTE Electronics, Inc, provides 15 A maximum collector current at 100 V breakdown voltage in the TO-220-3 package with 90 W power dissipation. This part is designed for high-power applications and offers substantially greater thermal capacity than the TIP30C. However, the BD912 is RoHS non-compliant, which may restrict its use in applications subject to RoHS regulations. Selection of this part requires confirmation that RoHS non-compliance is acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the TIP30CG be used as a direct replacement for the TIP30C?

A: Yes. The TIP30CG matches all electrical specifications of the TIP30C: 100 V breakdown voltage, 1 A maximum collector current, 2 W power dissipation, and 3 MHz transition frequency. Both use the TO-220-3 through-hole package. The TIP30CG is the recommended substitute due to its active product status and RoHS3 compliance.

Q: What is the difference between the TIP30C and TIP32CG?

A: The primary difference is maximum collector current: TIP30C is rated for 1 A, while TIP32CG is rated for 3 A. Both maintain 100 V breakdown voltage, 2 W power dissipation, 3 MHz transition frequency, and TO-220-3 packaging. The TIP32CG is suitable for applications requiring higher current capacity.

Q: Can I use the BD912 in place of the TIP30C?

A: The BD912 is electrically compatible with the TIP30C in terms of voltage rating (100 V) and package (TO-220-3). However, the BD912 is RoHS non-compliant, whereas the TIP30C is not subject to RoHS requirements due to its obsolete status. Use of the BD912 is restricted to applications where RoHS non-compliance is acceptable.

Q: Why do some substitute parts have higher current ratings than the TIP30C?

A: Higher-current alternatives (TIP32CG, TIP42CG, KSA1010YTU, BD912) are provided to support applications that exceed the 1 A specification of the TIP30C. These parts maintain the same 100 V voltage rating and TO-220-3 package, allowing them to function in circuits designed for the TIP30C while providing additional current capacity. Circuit verification is required to ensure the application can safely operate with the higher current capability.

Q: Are all substitute parts RoHS compliant?

A: No. The TIP30CG, KSA1010YTU, TIP32CG, and TIP42CG are RoHS3 compliant. The BD912 is RoHS non-compliant. Selection between compliant and non-compliant parts depends on regulatory requirements for the intended application.

Q: What is the significance of the TO-220-3 package for substitution?

A: The TO-220-3 package is a through-hole component with three leads (Base, Collector, Emitter for PNP transistors). All substitute parts listed maintain this package specification, ensuring mechanical and electrical compatibility with existing PCB layouts and circuit designs. No board redesign is required when substituting between these parts.

Q: Can I use the KSA1010YTU if my application requires 3 MHz transition frequency?

A: The KSA1010YTU does not specify a transition frequency value in the provided data. If 3 MHz transition frequency is a critical requirement for the application, the TIP30CG, TIP32CG, or TIP42CG are preferred, as all specify 3 MHz. Verification of the KSA1010YTU frequency response against application requirements is necessary before selection.

Q: What thermal considerations apply when selecting a substitute part?

A: The TIP30C is rated for 2 W power dissipation. Higher-current alternatives (TIP32CG, TIP42CG, KSA1010YTU) maintain or reduce this rating, while the BD912 provides 90 W dissipation. Selection of a higher-current part does not automatically provide better thermal performance; actual power dissipation depends on circuit operating conditions. The KSA1010YTU, with 1.5 W rating, may require additional thermal management compared to the TIP30C in high-current applications.
