TIP32A PBFREE Equivalent & Substitute Parts

Part Overview

The TIP32A PBFREE is a PNP bipolar junction transistor manufactured by Central Semiconductor Corp, designed for general-purpose switching and amplification applications. This device features a 60 V collector-emitter breakdown voltage, 3 A maximum collector current, and 40 W power dissipation capability in a Through Hole TO-220-3 package. The main part is classified as Obsolete, necessitating identification of active equivalent alternatives to ensure design continuity and procurement availability for new production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the TIP32A PBFREE is determined by strict electrical and mechanical parameter matching within the PNP bipolar transistor category. The following criteria establish valid substitution relationships:

Primary Matching Criteria:

• Transistor Type: PNP (mandatory)
• Current - Collector (Ic) Max: 3 A (mandatory)
• Voltage - Collector Emitter Breakdown (Max): 60 V (mandatory)
• Vce Saturation (Max) @ Ib, Ic: 1.2 V @ 375mA, 3A (mandatory)
• Current - Collector Cutoff (Max): 300 µA (mandatory)
• Frequency - Transition: 3 MHz (mandatory)
• Operating Temperature Range: -65°C to 150°C (mandatory)
• Mounting Type: Through Hole (mandatory)
• Package / Case: TO-220-3 (mandatory)

Secondary Considerations:

• Power dissipation capability (40 W for main part; variations noted in substitutes)
• DC Current Gain (hFE) specifications (variations noted in substitutes)
• Product Status and RoHS compliance

Identified substitutes meet all primary matching criteria. Variations in power rating and DC current gain are documented in the parameter comparison table and do not preclude substitution when application requirements are satisfied.

Engineering Selection Recommendations

TIP32AG (onsemi) - MFR Recommended Substitute: The TIP32AG is the manufacturer-recommended equivalent, supplied by onsemi in Active product status. This part maintains electrical equivalence across all primary parameters and carries ROHS3 compliance certification. The reduced power rating (2 W versus 40 W) and lower DC current gain specification (10 @ 3A, 4V versus 25 @ 1A, 4V) represent documented variations. Selection of this part is appropriate when onsemi supply chain and Active product status are prioritized.

TIP32A (Solid State Inc.) - Parametric Equivalent: The TIP32A from Solid State Inc. provides parametric equivalence with identical electrical specifications to the original TIP32A PBFREE, including 40 W power rating and 25 @ 1A, 4V DC current gain. This part is in Active product status and offers the highest inventory availability (36300 Pcs). Selection of this part is appropriate when full electrical equivalence and maximum supply availability are required.

Both substitutes satisfy the mandatory electrical and mechanical criteria for direct replacement in applications designed for the TIP32A PBFREE. Selection between them depends on supply chain requirements, inventory availability, and application-specific power dissipation demands.

Frequently Asked Questions (FAQ)

Q: Can the TIP32AG (onsemi) be used as a direct replacement for the TIP32A PBFREE?

A: The TIP32AG meets all mandatory electrical parameters: 3 A collector current, 60 V breakdown voltage, 1.2 V saturation voltage, 300 µA cutoff current, 3 MHz transition frequency, and identical operating temperature range. The TO-220-3 Through Hole package is identical. The reduced power rating (2 W) and lower DC current gain (10 @ 3A, 4V) are documented variations. Direct replacement is valid when application power dissipation does not exceed 2 W.

Q: What is the difference between the TIP32AG and the TIP32A from Solid State Inc.?

A: Both parts are electrically equivalent to the original TIP32A PBFREE across all primary parameters. The key difference is power rating: TIP32AG is rated 2 W, while the Solid State Inc. TIP32A is rated 40 W. DC current gain specifications also differ: TIP32AG specifies 10 @ 3A, 4V; Solid State Inc. TIP32A specifies 25 @ 1A, 4V. Selection depends on application power requirements and gain specifications.

Q: Are both substitutes in the same package?

A: Both substitutes use the TO-220-3 Through Hole package, identical to the original TIP32A PBFREE. Physical mounting and PCB layout compatibility are maintained.

Q: What is the significance of the Obsolete status for the original TIP32A PBFREE?

A: Obsolete status indicates the part is no longer manufactured by Central Semiconductor Corp. Both identified substitutes are in Active product status, ensuring long-term supply availability and continued manufacturing support.

Q: Are both substitutes RoHS3 compliant?

A: Both the TIP32AG (onsemi) and TIP32A (Solid State Inc.) are ROHS3 compliant, matching the compliance status of the original TIP32A PBFREE.
