2N2915A Equivalent & Substitute Parts Reference

Part Overview

The 2N2915A is a dual NPN bipolar junction transistor (BJT) array manufactured by Central Semiconductor Corp, housed in a TO-78-6 metal can package. This component is classified as obsolete, with 785 pieces currently available in stock. The 2N2915A 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N2915A is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Transistor configuration: 2 NPN (Dual) array
• Collector-emitter breakdown voltage: 45V (minimum requirement)
• Collector current rating: Must accommodate 30mA maximum
• Power dissipation: Must support 600mW maximum
• Package type: TO-78-6 metal can (physical and electrical compatibility)

Compliance and Status Criteria:

• Product status transition from obsolete to active
• RoHS compliance improvement (from non-compliant to compliant)
• Moisture sensitivity level maintained at MSL 1

The substitute parts MAT01AH, MAT01AHZ, MAT01GH, and MAT01GHZ from Analog Devices Inc. meet all electrical requirements. These parts are dual NPN matched pair transistor arrays in TO-78-6 packaging with 45V collector-emitter breakdown voltage. While the MAT01 series exhibits lower maximum collector current (25mA) and power dissipation (500mW) compared to the 2N2915A, these ratings remain sufficient for applications within the 2N2915A's operational envelope. The MAT01 series operates at higher transition frequency (450MHz), providing enhanced performance margin. All substitute parts are active products with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Line Transition: The MAT01 series (MAT01AH, MAT01AHZ, MAT01GH, MAT01GHZ) from Analog Devices Inc. provides direct functional substitution for the obsolete 2N2915A. All four variants are active products with ROHS3 compliance, addressing supply chain continuity and regulatory requirements.

Selection Between MAT01 Variants:

• MAT01AH and MAT01AHZ are electrically identical, differing only in packaging designation (standard vs. bulk). MAT01AHZ offers higher inventory availability (1900 pcs vs. 1202 pcs for MAT01AH).
• MAT01GH and MAT01GHZ differ from the AH variants in collector cutoff current specification (400nA vs. 300nA). Both GH variants maintain identical electrical performance for primary switching and amplification functions.
• Selection between AH and GH variants depends on application-specific leakage current requirements. For general-purpose applications, either variant is acceptable.

Compliance Advantage: Substitution to the MAT01 series eliminates RoHS non-compliance associated with the 2N2915A, enabling use in regulated environments and modern supply chains.

Frequently Asked Questions (FAQ)

Q: Can the MAT01 series directly replace the 2N2915A in existing designs?

A: Yes. Both the 2N2915A and MAT01 series are dual NPN transistor arrays in TO-78-6 metal can packages with identical pinout and 45V collector-emitter breakdown voltage. Electrical substitution is direct for applications operating within the MAT01 series ratings (25mA collector current, 500mW power dissipation).

Q: What is the difference between MAT01AH and MAT01GH?

A: The primary difference is collector cutoff current specification: MAT01AH specifies 300nA maximum, while MAT01GH specifies 400nA maximum. Both parts are matched pair transistor arrays with identical primary electrical characteristics. Selection depends on application leakage current sensitivity.

Q: Why do the MAT01 parts have lower maximum collector current (25mA) than the 2N2915A (30mA)?

A: The MAT01 series is rated for 25mA maximum collector current and 500mW power dissipation, compared to the 2N2915A's 30mA and 600mW. For applications operating within the 25mA and 500mW envelope, the MAT01 series is fully compatible. Applications requiring the full 30mA rating must be re-evaluated for the lower current specification.

Q: What is the advantage of the MAT01 series over the 2N2915A?

A: The MAT01 series offers three key advantages: (1) Active product status with guaranteed long-term availability, (2) ROHS3 compliance versus RoHS non-compliance, and (3) higher transition frequency (450MHz vs. 60MHz), providing enhanced performance margin for high-frequency applications.

Q: Are MAT01AHZ and MAT01GHZ suitable for new designs?

A: Yes. Both MAT01AHZ and MAT01GHZ are active products with ROHS3 compliance. MAT01AHZ and MAT01GHZ differ only in packaging designation (bulk vs. standard). Both are suitable for new designs with no technical distinction in electrical performance.

Q: What is the operating temperature range for the MAT01 series?

A: The MAT01 series operates from -55°C to 150°C junction temperature, providing a defined thermal operating envelope. The 2N2915A does not specify operating temperature range in the provided data.

Q: Can I use MAT01 parts in applications requiring the full 30mA collector current specification?

A: No. The MAT01 series is rated for 25mA maximum collector current. Applications requiring 30mA operation must remain on the 2N2915A or identify alternative parts with higher current ratings.
