Equivalent & Substitute Parts for 2N5884 PNP Power Transistor

Part Overview

The 2N5884 is a PNP bipolar junction transistor (BJT) rated for 80 V collector-emitter breakdown voltage and 25 A maximum collector current. This device is packaged in the TO-204 (TO-3) through-hole configuration and is designed for power amplification applications requiring high current handling capability. The 2N5884 is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement. Alternative parts must maintain compatibility with the electrical specifications and mechanical form factor of the original design.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2N5884 are classified into two categories based on electrical parameter compatibility:

Direct Equivalents maintain all critical electrical specifications including collector current rating (25 A), collector-emitter breakdown voltage (80 V), power dissipation (200 W), and transition frequency (4 MHz). These parts are pin-compatible and functionally interchangeable without circuit modification.

Similar Alternatives share the same transistor type (PNP), collector-emitter breakdown voltage (80 V), and package form factor (TO-204/TO-3) but differ in maximum collector current, power dissipation, or frequency response. These parts are suitable for applications where the full current or power rating of the 2N5884 is not required.

The substitution logic is based on the following key parameters:

• Transistor polarity (PNP)
• Collector-emitter breakdown voltage (80 V minimum)
• Package compatibility (TO-204/TO-3 through-hole)
• Collector current capability (25 A for direct equivalents; lower ratings for similar alternatives)
• Power dissipation rating (200 W for direct equivalents; lower ratings for similar alternatives)

Parameter Comparison

Engineering Selection Recommendations

2N5884 (Microchip Technology) is the primary direct equivalent. This part carries active product status and maintains the same base part number as the obsolete onsemi device. It is suitable for direct replacement in existing designs without electrical or mechanical modification.

2N6436 (Microchip Technology) is a direct equivalent classified as active. This part provides an alternative source for the 2N5884 specification and is available in bulk packaging.

2N5745 (Microchip Technology) is a similar alternative suitable for applications where the maximum collector current requirement is 20 A or less and power dissipation does not exceed 5 W. This part maintains the 80 V collector-emitter breakdown voltage and TO-204/TO-3 package compatibility. The reduced current and power ratings make this part unsuitable for designs requiring the full 25 A and 200 W capabilities of the 2N5884.

JAN2N5745 (Microchip Technology) is a military-grade variant (MIL-PRF-19500/433) with significantly reduced collector current rating (100 µA maximum). This part is not suitable as a general substitute for the 2N5884 due to its extremely limited current handling capability. This part is applicable only to low-signal military applications.

All substitute parts listed maintain RoHS non-compliance status consistent with the original 2N5884 device. REACH and ECCN classifications are identical across all parts.

Frequently Asked Questions (FAQ)

Q: Can the 2N5884 (Microchip) be used as a direct replacement for the 2N5884 (onsemi)?

A: Yes. Both parts share the same base part number and electrical specifications. The Microchip version is active and available for procurement, making it the primary substitute for the obsolete onsemi device.

Q: What is the difference between 2N6436 and 2N5884?

A: Both parts are direct equivalents with identical electrical ratings. The 2N6436 is an alternative part number from Microchip Technology that meets the same 80 V, 25 A, 200 W specification. Selection between these parts depends on availability and supplier preference.

Q: Can 2N5745 replace 2N5884 in all applications?

A: No. The 2N5745 has reduced maximum collector current (20 A versus 25 A) and significantly lower power dissipation (5 W versus 200 W). This part is suitable only for applications where these reduced ratings are acceptable. Designs requiring the full 25 A current or 200 W power capability must use 2N5884, 2N5884 (Microchip), or 2N6436.

Q: Is JAN2N5745 suitable as a substitute for 2N5884?

A: No. The JAN2N5745 is a military-grade device with a maximum collector current of 100 µA, making it unsuitable for general power amplification applications. This part is designed for low-signal military applications and does not meet the current or power requirements of the 2N5884.

Q: Are all substitute parts available in the same TO-204/TO-3 package?

A: Yes. All listed substitute parts use the TO-204AA or TO-3 through-hole package, ensuring mechanical compatibility with existing PCB designs and socket configurations.

Q: What is the temperature operating range difference between 2N5884 and 2N5745?

A: The 2N5884 operates from -65°C to 200°C, while 2N5745 and JAN2N5745 operate from -55°C to 200°C. Applications requiring operation below -55°C must use the 2N5884 or equivalent parts with the extended lower temperature rating.

Q: Are there RoHS-compliant alternatives to 2N5884?

A: No. All listed substitute parts, including the active Microchip versions, maintain RoHS non-compliant status consistent with the original 2N5884 device.
