Bourns 2036-40-C2 Gas Discharge Tube: Equivalent & Substitute Parts

Part Overview

The Bourns 2036-40-C2 is a 3-pole gas discharge tube (GDT) rated for 400V DC spark-over voltage with 10kA impulse discharge current capacity. This component is designed for overvoltage protection in through-hole applications using an axial cylinder configuration with radial bend leads. The 2036-40-C2 is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2036-40-C2 is determined by matching the following critical electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 400 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Tolerance: ±20%
• Number of Poles: 3
• Fail Short characteristic: No
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• Series: Mini-TRIGARD™ 2036

The 2036-40-B2 meets all specified electrical and mechanical requirements, differing only in product status (active vs. obsolete) and packaging format (tray vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The 2036-40-B2 is the direct substitute for the obsolete 2036-40-C2. Both components are manufactured by Bourns Inc. within the Mini-TRIGARD™ 2036 series and share identical electrical specifications and mechanical form factors. The 2036-40-B2 maintains active product status, ensuring continued availability and supply chain reliability.
