TIP32A Equivalent & Substitute Parts

Part Overview

The TIP32A is a PNP bipolar junction transistor manufactured by STMicroelectronics, rated for 60 V collector-emitter breakdown voltage and 3 A maximum collector current in a TO-220 through-hole package. This device is classified as obsolete, making identification of active equivalent parts necessary for ongoing design support and procurement continuity. The TIP32A serves in applications requiring medium-power PNP switching and amplification functions within the specified voltage and current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP32A is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

Electrical Parameters (Must Match):

• Transistor Type: PNP
• Current - Collector (Ic) Max: 3 A
• Voltage - Collector Emitter Breakdown (Max): 60 V
• Vce Saturation (Max) @ Ib, Ic: 1.2 V @ 375mA, 3A
• Current - Collector Cutoff (Max): 300 µA
• DC Current Gain (hFE) Min @ Ic, Vce: 10 @ 3A, 4V
• Power - Max: 2 W

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-220-3

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The TIP32AG meets all specified electrical and mechanical parameters and maintains equivalent compliance certifications, establishing it as a direct substitute for the obsolete TIP32A.

Parameter Comparison

Engineering Selection Recommendations

The TIP32AG manufactured by onsemi is a direct electrical and mechanical equivalent to the obsolete TIP32A. Both devices share identical ratings for collector current, collector-emitter breakdown voltage, saturation voltage, cutoff current, DC current gain, and power dissipation. Both are packaged in TO-220-3 through-hole configuration and maintain ROHS3 compliance and REACH unaffected status.

The primary distinction is product status: the TIP32A is obsolete while the TIP32AG is active. The TIP32AG provides ongoing availability and supply chain continuity for applications currently using or designed around TIP32A specifications. The electrical performance and compliance profile of the TIP32AG ensures functional equivalence in existing circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can the TIP32AG directly replace the TIP32A in existing designs?

A: Yes. The TIP32AG meets all electrical specifications of the TIP32A, including collector current rating (3 A), collector-emitter breakdown voltage (60 V), saturation voltage (1.2 V @ 375mA, 3A), and DC current gain (10 @ 3A, 4V). Both devices use the TO-220-3 package and maintain identical compliance certifications.

Q: What is the primary reason to substitute the TIP32A?

A: The TIP32A is classified as obsolete. The TIP32AG is an active product from onsemi that provides equivalent electrical and mechanical performance with assured long-term availability.

Q: Are there any differences in operating temperature range between these devices?

A: The TIP32A specifies a maximum operating temperature of 150°C. The TIP32AG specifies an operating temperature range of −65°C to 150°C. Both devices operate within the same maximum temperature limit; the TIP32AG provides extended lower temperature capability.

Q: Do both devices have the same package configuration?

A: Yes. Both the TIP32A and TIP32AG use the TO-220-3 through-hole package, ensuring mechanical compatibility in PCB layouts and thermal management designs.

Q: Are compliance certifications equivalent?

A: Yes. Both devices are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What is the difference in packaging format between the two parts?

A: The TIP32A is supplied in standard packaging, while the TIP32AG is supplied in tube packaging. Both formats contain the same device; the packaging format does not affect electrical performance or circuit compatibility.
