TIP30ATU Equivalent & Substitute Parts

Part Overview

The TIP30ATU is a PNP bipolar junction transistor manufactured by onsemi, rated for 60V collector-emitter breakdown voltage and 1A maximum collector current in a TO-220-3 through-hole package. This device is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and production continuity. The TIP30ATU delivers 2W maximum power dissipation with a 3MHz transition frequency, suitable for general-purpose switching and amplification applications requiring moderate current handling.

Substitute Part Grouping Explanation

Substitution of the TIP30ATU is determined by strict equivalence across the following electrical and mechanical parameters:

Mandatory Matching Criteria:

Transistor polarity: PNP configuration
Collector-emitter breakdown voltage: 60V maximum rating
Package type: TO-220-3 through-hole configuration
Mounting method: Through-hole assembly
Power dissipation capability: 2W maximum
Transition frequency: 3MHz

Allowable Variation Criteria:

Maximum collector current: Substitute may exceed 1A specification
DC current gain (hFE): Substitute may differ from specified minimum
Collector cutoff current: Substitute may differ from specified maximum
Vce saturation: Substitute may differ from specified maximum
Product status: Active status preferred over obsolete
Compliance certifications: Enhanced compliance acceptable

The TIP32AG qualifies as a direct substitute based on matching all mandatory criteria while providing enhanced electrical performance characteristics and active product status.

Engineering Selection Recommendations

TIP32AG as Primary Substitute:

The TIP32AG is the appropriate substitute for the obsolete TIP30ATU. Both devices share identical voltage ratings (60V), package configuration (TO-220-3), power dissipation (2W), and transition frequency (3MHz). The TIP32AG provides enhanced collector current capability (3A versus 1A), which does not restrict its use in applications designed for the TIP30ATU. The TIP32AG maintains active product status with RoHS3 compliance certification, ensuring long-term availability and regulatory alignment. Both devices carry REACH Unaffected status and identical ECCN/HTSUS classifications.

Compliance Considerations:

The TIP32AG incorporates RoHS3 compliance, whereas the TIP30ATU does not specify this certification. For applications requiring RoHS compliance, the TIP32AG satisfies regulatory requirements. Both devices are REACH Unaffected, indicating no restriction of use under REACH regulations.

Inventory and Supply:

The TIP32AG maintains active inventory status (2455 units in stock) compared to the TIP30ATU's obsolete classification, supporting production continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the TIP32AG directly replace the TIP30ATU in existing circuit designs?

A: Yes. The TIP32AG matches all mandatory electrical and mechanical parameters: 60V breakdown voltage, TO-220-3 package, 2W power rating, and 3MHz transition frequency. The higher collector current rating (3A) does not prevent substitution in circuits designed for 1A operation.

Q: What is the primary advantage of using TIP32AG over TIP30ATU?

A: The TIP32AG is an active product with current manufacturing support, whereas the TIP30ATU is obsolete. The TIP32AG also provides RoHS3 compliance certification and higher collector current capability (3A), offering design flexibility for future applications.

Q: Are there package differences between TIP30ATU and TIP32AG?

A: Both devices use the TO-220-3 through-hole package. The TIP32AG is supplied in tube packaging, while the TIP30ATU packaging type is not specified. The physical package dimensions and pin configuration are identical.

Q: Do operating temperature ranges differ between these devices?

A: The TIP30ATU specifies a maximum junction temperature of 150°C without a minimum rating. The TIP32AG specifies an operating range of −65°C to 150°C, providing defined low-temperature performance. Both devices support the same maximum operating temperature.

Q: What are the DC current gain differences?

A: The TIP30ATU specifies minimum hFE of 15 at 1A and 4V. The TIP32AG specifies minimum hFE of 10 at 3A and 4V. The TIP32AG's lower hFE at higher current does not restrict substitution in applications designed for the TIP30ATU.

Q: Are there moisture sensitivity differences?

A: The TIP30ATU specifies MSL 1 (Unlimited). The TIP32AG lists MSL as Not Applicable. Both classifications indicate minimal moisture sensitivity risk during storage and handling.
