2N5114 JFET P-Channel Transistor: Equivalent & Substitute Parts

Part Overview

The 2N5114 is a P-channel JFET (Junction Field-Effect Transistor) in TO-206AA (TO-18) metal can package, rated for 30 V operation and 500 mW power dissipation. Originally manufactured by Vishay Siliconix, this part is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2N5114 is determined by the following mandatory parameters:

• Drain to Source Voltage (Vdss): Must be ≥ 30 V
• Power Dissipation: Must be ≥ 500 mW
• FET Type: Must be P-Channel
• Package: Must be TO-206AA or TO-18 metal can (through hole)
• Input Capacitance (Ciss): Must be ≤ 25 pF @ 15V

All substitute parts listed below meet these electrical and mechanical requirements and are pin-compatible with the original 2N5114 in identical package configurations.

Engineering Selection Recommendations

For Active Production and New Designs:

The Microchip Technology 2N5114 is the primary substitute. It maintains identical part numbering, carries active product status, holds military-grade qualification (MIL-PRF-19500), and meets all electrical and mechanical parameters of the original Vishay part. This option provides the highest compatibility assurance and supply chain stability.

For Applications Requiring RoHS3 Compliance:

The Solid State Inc. 2N5116 is suitable when RoHS3 compliance is mandatory. It meets all core electrical parameters and package requirements. Note that RoHS compliance status differs from the original part.

For Drain Current Optimization:

The Microchip 2N5115 offers an alternative with lower drain current (Idss = 60 mA @ 15V) and higher on-resistance (RDS(On) = 100 Ohms) compared to the Microchip 2N5114 (Idss = 90 mA @ 18V, RDS(On) = 75 Ohms). Selection between these variants depends on circuit requirements for current handling and switching characteristics.

All substitute parts are through-hole mounted in identical TO-18 metal can packages and are pin-compatible with the original 2N5114.

Frequently Asked Questions (FAQ)

Q: Can the 2N5114 be directly replaced with the Microchip 2N5114?

A: Yes. Both parts share identical part numbering, package configuration (TO-206AA/TO-18), and pin assignments. The Microchip version is an active product with military qualification, making it the direct functional equivalent.

Q: What is the difference between 2N5114 and 2N5115?

A: Both are P-channel JFETs in TO-18 packages with 30 V Vdss and 500 mW power rating. The 2N5115 has lower drain current (60 mA @ 15V vs. 90 mA @ 18V) and higher on-resistance (100 Ohms vs. 75 Ohms). Selection depends on whether lower current or lower resistance is required for the application.

Q: Is the 2N5116 from Solid State Inc. a suitable replacement?

A: Yes, the 2N5116 meets all core electrical parameters (30 V Vdss, 500 mW, P-channel, 25 pF Ciss) and uses the identical TO-18 package. It is suitable for applications where RoHS3 compliance is required. On-resistance is higher at 150 Ohms.

Q: Are all substitute parts pin-compatible?

A: Yes. All listed substitutes use the TO-206AA (TO-18) metal can package with identical pin configurations, enabling direct board-level replacement without layout modifications.

Q: What compliance certifications apply to these substitutes?

A: The Microchip 2N5114 and 2N5115 carry MIL-PRF-19500 military qualification. The Solid State Inc. 2N5116 is RoHS3 compliant. All parts are EAR99 classified and REACH unaffected.

Q: Why is the original Vishay 2N5114 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production by the original manufacturer. Active substitutes from Microchip Technology and Solid State Inc. ensure continued availability and design support.
