TIP30B-BP Equivalent & Substitute Parts

Part Overview

The TIP30B-BP is a PNP bipolar junction transistor manufactured by Micro Commercial Co, rated for 80 V collector-emitter breakdown voltage and 1 A maximum collector current in a TO-220AB through-hole package. This component is classified as obsolete, making identification of suitable substitute parts necessary for ongoing design support and production continuity. The TIP30B-BP delivers 30 W maximum power dissipation with a 3 MHz transition frequency, suitable for general-purpose switching and amplification applications requiring moderate current and voltage ratings.

Substitute Part Grouping Explanation

Substitution of the TIP30B-BP is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Transistor type must be PNP
Package must be TO-220-3 (TO-220AB supplier device package)
Mounting type must be Through Hole
Transition frequency must be 3 MHz or greater
Collector-emitter breakdown voltage must equal or exceed 80 V
Maximum collector current must equal or exceed 1 A
RoHS3 compliance required

The TIP32C-BP meets all substitution criteria. While the TIP32C-BP exhibits higher maximum ratings in collector current (3 A), collector-emitter breakdown voltage (100 V), and different saturation characteristics, these parameters remain within acceptable substitution boundaries for applications designed for the TIP30B-BP. The identical package, mounting type, transition frequency, and compliance certifications ensure mechanical and electrical compatibility.

Engineering Selection Recommendations

The TIP32C-BP is the designated substitute for the obsolete TIP30B-BP. Selection of the TIP32C-BP is supported by the following factors:

Product Status: The TIP32C-BP maintains active product status with confirmed inventory availability (4568 pcs), whereas the TIP30B-BP is obsolete. This ensures long-term supply chain continuity and manufacturing support.

Compliance Certifications: Both components maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with current manufacturing and environmental standards.

Electrical Compatibility: The TIP32C-BP provides equal or superior electrical performance across all critical parameters. The higher collector-emitter breakdown voltage (100 V vs. 80 V) and collector current rating (3 A vs. 1 A) establish a conservative design margin for applications originally specified for the TIP30B-BP.

Mechanical Compatibility: Identical TO-220-3 package and through-hole mounting configuration ensure direct physical substitution without PCB redesign or mechanical rework.

Frequency Performance: Both components operate at 3 MHz transition frequency, maintaining equivalent switching characteristics for the intended application class.

Frequently Asked Questions (FAQ)

Q: Can the TIP32C-BP directly replace the TIP30B-BP in existing designs?

A: Yes. The TIP32C-BP is mechanically and electrically compatible with the TIP30B-BP. Both components use the TO-220-3 package with identical pin configuration and through-hole mounting. The TIP32C-BP provides equal or superior electrical performance across all critical parameters.

Q: What are the key differences between the TIP30B-BP and TIP32C-BP?

A: The primary differences are collector-emitter breakdown voltage (80 V vs. 100 V), maximum collector current (1 A vs. 3 A), maximum power dissipation (30 W vs. 2 W), and product status (obsolete vs. active). The TIP32C-BP offers higher voltage and current ratings, establishing a conservative design margin.

Q: Are there any package or pinout differences?

A: No. Both components use the TO-220-3 package with identical pinout. Direct PCB substitution is possible without modification.

Q: What is the significance of the TIP30B-BP being obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by the original supplier. The TIP32C-BP, with active product status and confirmed inventory, provides supply chain continuity for new production and design support.

Q: Do both components meet current environmental compliance standards?

A: Yes. Both the TIP30B-BP and TIP32C-BP are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, meeting current manufacturing and environmental requirements.

Q: What is the operating temperature range for both components?

A: Both components operate across a junction temperature range of -55°C to 150°C, providing identical thermal performance specifications.

Q: Are there any DC current gain differences that affect circuit design?

A: Yes. The TIP30B-BP specifies a minimum DC current gain (hFE) of 40 at 200 mA and 4 V, while the TIP32C-BP specifies a minimum of 10 at 3 A and 4 V. For applications operating at lower collector currents, the TIP30B-BP exhibits higher current gain. However, the TIP32C-BP remains suitable for designs originally specified for the TIP30B-BP.
