2N2914 Equivalent & Substitute Parts

Part Overview

The 2N2914 is a dual NPN bipolar junction transistor (BJT) array manufactured by Central Semiconductor Corp in a TO-78-6 metal can package. This component is classified as obsolete, with 848 pieces currently in stock. The 2N2914 operates at maximum collector current of 30mA, collector-emitter breakdown voltage of 45V, and maximum power dissipation of 600mW, with a transition frequency of 60MHz. Due to its obsolete status, equivalent substitute parts from active product lines are necessary for new designs and long-term supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the 2N2914 is based on the following critical parameters that must be maintained or exceeded:

Mandatory Compatibility Parameters:

Package / Case: TO-78-6 Metal Can (identical mechanical and electrical interface)
Transistor Type: 2 NPN (Dual) configuration
Voltage - Collector Emitter Breakdown (Max): 45V minimum
Mounting Type: Through Hole

Performance Parameters:

Current - Collector (Ic) (Max): 30mA or greater
Power - Max: 600mW or greater
Frequency - Transition: 60MHz or greater

The substitute parts MAT01AH, MAT01AHZ, MAT01GH, and MAT01GHZ from Analog Devices Inc. meet all mandatory compatibility requirements. These parts are matched-pair dual NPN transistor arrays in TO-78-6 packages with identical mechanical interfaces. All substitutes operate at 45V collector-emitter breakdown voltage, support 25mA collector current (within the 30mA specification), deliver 500mW power dissipation (within the 600mW specification), and feature 450MHz transition frequency (exceeding the 60MHz requirement).

Engineering Selection Recommendations

Product Status Consideration: The 2N2914 is classified as obsolete. All four substitute parts (MAT01AH, MAT01AHZ, MAT01GH, MAT01GHZ) are active products from Analog Devices Inc., ensuring long-term availability and supply chain stability.

Compliance and Certification: The 2N2914 is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for new equipment designs and procurement standards.

Electrical Compatibility: All substitute parts maintain the 45V collector-emitter breakdown voltage specification. The 25mA maximum collector current of the substitutes is within the 30mA specification of the 2N2914. The 500mW power dissipation of the substitutes is within the 600mW specification. The 450MHz transition frequency of the substitutes exceeds the 60MHz requirement, providing enhanced performance margin.

Packaging and Mechanical Interface: All substitute parts use the identical TO-78-6 metal can package with through-hole mounting, ensuring direct mechanical and electrical compatibility with existing PCB designs.

Variant Selection: MAT01AH and MAT01AHZ are functionally equivalent, with MAT01AHZ available in bulk packaging. MAT01GH and MAT01GHZ are functionally equivalent, with MAT01GHZ available in bulk packaging. The primary difference between the AH and GH variants is the maximum collector cutoff current specification (300nA versus 400nA), which does not affect substitution suitability for the 2N2914 application.

Frequently Asked Questions (FAQ)

Q: Can the MAT01 series parts directly replace the 2N2914 in existing designs?

A: Yes. The MAT01AH, MAT01AHZ, MAT01GH, and MAT01GHZ parts are direct mechanical and electrical substitutes for the 2N2914. All parts use the TO-78-6 metal can package with identical pinout and through-hole mounting. The electrical specifications of the substitutes meet or exceed the 2N2914 requirements for collector-emitter breakdown voltage (45V), collector current (25mA within the 30mA specification), and power dissipation (500mW within the 600mW specification).

Q: What is the difference between MAT01AH and MAT01GH?

A: Both MAT01AH and MAT01GH are dual NPN matched-pair transistor arrays in TO-78-6 packages with identical electrical performance for the 2N2914 substitution application. The primary difference is the maximum collector cutoff current specification: MAT01AH specifies 300nA maximum, while MAT01GH specifies 400nA maximum. This difference does not affect substitution suitability.

Q: What is the difference between MAT01AH and MAT01AHZ?

A: MAT01AH and MAT01AHZ are electrically identical parts. The primary difference is packaging: MAT01AH is supplied in standard packaging, while MAT01AHZ is supplied in bulk packaging. Both are suitable substitutes for the 2N2914.

Q: Why are the MAT01 substitutes rated for 25mA collector current when the 2N2914 is rated for 30mA?

A: The 25mA maximum collector current specification of the MAT01 series is within the 30mA specification of the 2N2914. This means the MAT01 parts can safely operate at currents up to 25mA, which covers the operating range of the 2N2914 in typical applications. If an application requires collector currents exceeding 25mA, the MAT01 series would not be suitable.

Q: Are the MAT01 substitutes RoHS compliant?

A: Yes. All MAT01 substitute parts (MAT01AH, MAT01AHZ, MAT01GH, MAT01GHZ) are ROHS3 compliant. The original 2N2914 is RoHS non-compliant. This compliance upgrade is beneficial for new designs and procurement requirements.

Q: What is the operating temperature range of the MAT01 substitutes?

A: All MAT01 substitute parts operate over the temperature range of -55°C to 150°C (junction temperature). The 2N2914 operating temperature specification was not provided in the available data.

Q: Can I use MAT01GHZ in bulk packaging for production assembly?

A: Yes. MAT01GHZ is supplied in bulk packaging and is electrically and mechanically identical to the other MAT01 variants. Bulk packaging is suitable for automated assembly processes and high-volume production.

Q: What is the transition frequency of the MAT01 substitutes compared to the 2N2914?

A: The MAT01 series has a transition frequency of 450MHz, which exceeds the 2N2914 specification of 60MHz. This higher frequency capability provides enhanced performance margin and is beneficial for applications requiring faster switching characteristics.
