Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIP32A-BP is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor polarity: PNP
• Maximum collector current: 3 A
• Package type: TO-220-3 through-hole configuration
• Vce saturation characteristics: 1.2 V @ 375 mA, 3 A
• DC current gain: minimum 10 @ 3 A, 4 V
• Power dissipation: 2 W maximum
• Transition frequency: 3 MHz

Voltage Rating Considerations: Substitute parts are grouped based on collector-emitter breakdown voltage. The TIP32A-BP specifies 60 V maximum. Substitutes with equal or higher voltage ratings are electrically compatible for applications designed around the 60 V specification. Substitutes with lower voltage ratings are not suitable for direct replacement in circuits requiring 60 V operation.

Compliance and Status: All substitute parts listed maintain ROHS3 compliance and EAR99 ECCN classification, ensuring regulatory compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

TIP32AG (onsemi) - Parametric Equivalent

The TIP32AG is a parametric equivalent to the TIP32A-BP. Both devices share identical electrical specifications: 60 V collector-emitter breakdown voltage, 3 A maximum collector current, 1.2 V Vce saturation, 10 minimum DC current gain, 2 W power rating, and 3 MHz transition frequency. The TIP32AG is manufactured by onsemi and carries Active product status, ensuring continued availability and support. Operating temperature range extends to -65°C, providing broader environmental coverage than the TIP32A-BP. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications. The TIP32AG is suitable for direct replacement in applications where the 60 V voltage specification is required.

TIP32G (onsemi) - Voltage-Derated Substitute

The TIP32G is a substitute part with reduced collector-emitter breakdown voltage of 40 V, compared to the 60 V specification of the TIP32A-BP. All other electrical parameters remain identical: 3 A maximum collector current, 1.2 V Vce saturation, 10 minimum DC current gain, 2 W power rating, and 3 MHz transition frequency. The TIP32G is manufactured by onsemi with Active product status. This part is suitable for applications where the circuit design operates at or below 40 V collector-emitter voltage. The TIP32G is not suitable for direct replacement in circuits designed for 60 V operation.

Both substitute parts are manufactured by onsemi, an established semiconductor manufacturer, and maintain full ROHS3 compliance and regulatory alignment with the original TIP32A-BP.

Frequently Asked Questions (FAQ)

Q: Can the TIP32AG be used as a direct replacement for the TIP32A-BP?

A: Yes. The TIP32AG meets all electrical and mechanical specifications of the TIP32A-BP, including 60 V collector-emitter breakdown voltage, 3 A maximum collector current, identical saturation characteristics, and TO-220-3 package configuration. Both parts are ROHS3 compliant.

Q: What is the key difference between the TIP32AG and TIP32G?

A: The primary difference is collector-emitter breakdown voltage. The TIP32AG is rated for 60 V, matching the TIP32A-BP specification. The TIP32G is rated for 40 V. All other electrical parameters are identical. Selection depends on the voltage requirements of the application circuit.

Q: Can the TIP32G replace the TIP32A-BP in all applications?

A: No. The TIP32G is suitable only for applications where the circuit design operates at or below 40 V collector-emitter voltage. For circuits designed around the 60 V specification, the TIP32G does not provide equivalent voltage headroom and is not a suitable replacement.

Q: Are the package configurations identical between all three parts?

A: Yes. The TIP32A-BP, TIP32AG, and TIP32G all use the TO-220-3 through-hole package configuration, ensuring mechanical compatibility and identical PCB footprints.

Q: What is the significance of the TIP32A-BP being marked "Not For New Designs"?

A: This designation indicates the part has been superseded by the manufacturer and is no longer recommended for new product development. However, the part remains available for legacy system support and maintenance. The TIP32AG and TIP32G, both with Active status, are the current production alternatives.

Q: Do all three parts meet the same compliance standards?

A: Yes. The TIP32A-BP, TIP32AG, and TIP32G are all ROHS3 compliant, carry EAR99 ECCN classification, and share identical HTSUS codes, ensuring regulatory compatibility across all three parts.

Q: What is the operating temperature range for each part?

A: The TIP32A-BP specifies a maximum junction temperature of 150°C. The TIP32AG and TIP32G both specify an operating temperature range of -65°C to 150°C, providing extended low-temperature capability.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Current inventory levels differ: TIP32A-BP has 632 units in stock, TIP32AG has 2455 units, and TIP32G has 2504 units. For applications requiring immediate availability, the onsemi alternatives offer higher stock levels.
