2N2917 Equivalent & Substitute Parts Reference

Part Overview

The 2N2917 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 885 pieces currently available in stock. The 2N2917 operates at a 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 2N2917 is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the TO-78-6 metal can through-hole package to ensure mechanical and electrical compatibility with existing PCB layouts.

Electrical Ratings: Substitute parts must meet or exceed the voltage rating (45V collector-emitter breakdown) and support the required collector current. The 2N2917 specifies a maximum collector current of 30mA; substitute parts with lower maximum ratings (25mA) remain functionally compatible for applications operating within the 25mA threshold.

Transistor Configuration: All substitutes must be dual NPN transistor arrays to maintain functional equivalence.

Compliance Status: The 2N2917 is RoHS non-compliant and obsolete. Active substitute parts from the MAT01 series (Analog Devices Inc.) are ROHS3 compliant and maintain active product status, providing improved supply chain reliability and regulatory compliance.

The MAT01 series substitutes (MAT01AH, MAT01AHZ, MAT01GH, MAT01GHZ) are matched-pair transistor arrays with enhanced performance characteristics, including higher transition frequency (450MHz versus 60MHz) and lower power dissipation (500mW versus 600mW), while maintaining the same 45V voltage rating and TO-78-6 package.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes: MAT01AH, MAT01AHZ, MAT01GH, and MAT01GHZ are direct functional equivalents for the 2N2917 in TO-78-6 package applications.

Compliance Advantage: All MAT01 series substitutes are ROHS3 compliant, addressing regulatory requirements that the obsolete 2N2917 does not meet. This compliance status is essential for new product designs and applications subject to RoHS directives.

Active Product Status: The MAT01 series maintains active product status with Analog Devices Inc., ensuring long-term availability and supply chain stability. The 2N2917's obsolete classification presents supply risk for ongoing production and field replacements.

Current Rating Consideration: The MAT01 series specifies a maximum collector current of 25mA, compared to the 2N2917's 30mA rating. Applications requiring collector currents between 25mA and 30mA must be evaluated against actual circuit operating points. For applications operating at or below 25mA, substitution is direct.

Performance Enhancement: The MAT01 series provides superior frequency performance (450MHz transition frequency versus 60MHz), lower power dissipation (500mW versus 600mW), and matched-pair characteristics that improve circuit performance in precision applications.

Packaging and Inventory: All substitute parts are available in TO-78-6 metal can through-hole packages with substantial inventory levels (1202 to 1900 pieces), supporting both prototype and production requirements.

Frequently Asked Questions (FAQ)

Q: Can MAT01 series parts directly replace the 2N2917 in existing designs?

A: Yes, for applications operating at collector currents of 25mA or below. The MAT01 series maintains the same 45V voltage rating, TO-78-6 package, and dual NPN configuration. Applications requiring collector currents between 25mA and 30mA require circuit evaluation to confirm operation within the 25mA maximum rating of the substitute.

Q: What is the difference between MAT01AH, MAT01AHZ, MAT01GH, and MAT01GHZ?

A: All four parts are functionally equivalent dual NPN matched-pair transistor arrays in TO-78-6 packages with identical electrical ratings. The primary differences are collector cutoff current specifications (MAT01AH and MAT01AHZ specify 300nA maximum; MAT01GH and MAT01GHZ specify 400nA maximum) and packaging format (MAT01GHZ is supplied in bulk packaging). Selection depends on application requirements for leakage current and packaging preferences.

Q: Why is the 2N2917 classified as obsolete?

A: The 2N2917 is no longer in active production by Central Semiconductor Corp. Obsolete classification indicates the manufacturer has discontinued the product line. Existing inventory is limited to available stock, and long-term supply cannot be guaranteed.

Q: Are the MAT01 series parts RoHS compliant?

A: Yes, all MAT01 series parts (MAT01AH, MAT01AHZ, MAT01GH, MAT01GHZ) are ROHS3 compliant. The 2N2917 is RoHS non-compliant. This compliance difference is significant for new designs and applications subject to RoHS directives.

Q: What is the significance of the matched-pair designation in the MAT01 series?

A: The MAT01 series are matched-pair transistor arrays, meaning the two transistors within each package are characterized for closely matched electrical parameters. This is beneficial for precision applications requiring balanced performance between the two transistors, such as differential amplifiers and balanced circuits. The 2N2917 does not specify matched-pair characteristics.

Q: Can I use MAT01 parts in applications originally designed for the 2N2917?

A: Yes, provided the application operates at collector currents of 25mA or below and does not require the specific performance characteristics of the 2N2917. The MAT01 series offers superior frequency response and lower power dissipation, making them suitable for most applications. Verify that the 25mA maximum collector current rating is compatible with your circuit design.

Q: What is the difference between MAT01GHZ and MAT01GH?

A: MAT01GHZ and MAT01GH are electrically identical. The primary difference is packaging format: MAT01GHZ is supplied in bulk packaging, while MAT01GH uses standard packaging. Both are ROHS3 compliant and active products with identical electrical specifications.
