2N5116 JFET P-Channel Transistor: Equivalent & Substitute Parts

Part Overview

The 2N5116 is a P-channel JFET (Junction Field-Effect Transistor) in TO-206AA (TO-18) metal can package, rated for 30V operation and 500mW power dissipation. Manufactured by Vishay Siliconix, this component is classified as obsolete. Due to its obsolete status and limited availability from the original manufacturer, identifying qualified substitute parts is essential for design continuity and procurement reliability. Substitute parts must maintain electrical compatibility across voltage ratings, power handling, and package specifications while meeting modern compliance requirements where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2N5116 is determined by the following criteria:

• FET Type: Must be P-Channel JFET
• Package / Case: Must be TO-206AA or TO-18-3 Metal Can (through-hole)
• Voltage Rating: Minimum 30V breakdown voltage (V(BR)GSS) or equivalent drain-source voltage (Vdss)
• Power Rating: Minimum 500mW power dissipation capability
• Mounting Type: Through-hole configuration required

All substitute parts listed below satisfy these core electrical and mechanical parameters, ensuring direct functional replacement in existing circuit designs without layout or footprint modifications.

Engineering Selection Recommendations

Active Product Substitutes: The 2N5116 (Solid State Inc.), 2N5114, 2N5115, and MV2N5116 (all Microchip Technology) are all active products with current manufacturing status, providing superior long-term availability compared to the obsolete Vishay Siliconix original.

Military-Grade Options: The 2N5114, 2N5115, and MV2N5116 from Microchip Technology carry military-grade qualification (MIL-PRF-19500) and extended operating temperature range (-65°C to 200°C), suitable for applications requiring enhanced reliability and environmental performance.

RoHS Compliance: The 2N5116 from Solid State Inc. is ROHS3 compliant, meeting modern environmental and regulatory requirements. The Microchip alternatives maintain RoHS non-compliant status consistent with the original part.

Electrical Performance Variation: While all substitutes maintain the 30V voltage rating and 500mW power specification, RDS(On) values vary (75Ohms to 150Ohms) and drain current characteristics differ. Selection should account for circuit-specific impedance and current requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace a 2N5116 with any of these substitute parts?

A: Yes, all listed substitutes are electrically and mechanically compatible. They share identical TO-206AA (TO-18) packaging, 30V voltage rating, and 500mW power capability. Pin configuration and functional behavior remain consistent across all variants.

Q: What is the primary reason to substitute the original 2N5116?

A: The original 2N5116 from Vishay Siliconix is obsolete. Active alternatives from Solid State Inc. and Microchip Technology ensure reliable procurement and long-term supply chain stability.

Q: Are there differences in on-resistance (RDS(On)) between substitutes?

A: Yes. The 2N5114 offers the lowest RDS(On) at 75 Ohms, while the 2N5116 from Solid State Inc. has the highest at 150 Ohms. The 2N5115 and MV2N5116 are rated at 100 Ohms. Circuit designs sensitive to channel resistance should account for these variations.

Q: Which substitute offers the best environmental performance?

A: The 2N5114, 2N5115, and MV2N5116 from Microchip Technology provide military-grade qualification (MIL-PRF-19500) and extended temperature range (-65°C to 200°C), exceeding standard commercial specifications.

Q: Is RoHS compliance a factor in selecting a substitute?

A: The 2N5116 from Solid State Inc. is ROHS3 compliant, meeting modern environmental directives. If RoHS compliance is a design requirement, this option is preferred. The Microchip alternatives maintain non-compliant status matching the original part.

Q: Do all substitutes have the same package footprint?

A: Yes. All substitutes use TO-206AA (TO-18-3 Metal Can) through-hole packaging with identical pin configuration and mechanical dimensions. No PCB layout modifications are required.
