Bourns 2036-40-C2LF Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2036-40-C2LF is a Gas Discharge Tube (GDT) rated for 400V DC spark-over voltage with 10kA impulse discharge current capacity in a 3-pole through-hole configuration. This component is classified as Obsolete, necessitating identification of active equivalent parts for continued system design and procurement. The Mini-TRIGARD™ 2036 series provides direct functional alternatives with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2036-40-C2LF is determined by strict equivalence across the following critical 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 substitute part 2036-40-B2LF meets all these criteria and is manufactured by Bourns Inc. within the same product series. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The 2036-40-B2LF is the direct functional equivalent for the obsolete 2036-40-C2LF. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part maintains identical electrical performance and mechanical form factor. The primary difference is product status: the 2036-40-B2LF is Active and available through standard procurement channels, while the 2036-40-C2LF is Obsolete. Packaging format differs (Tray versus Tube), which may affect procurement quantities and handling procedures but does not impact component functionality or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the 2036-40-B2LF directly replace the 2036-40-C2LF in existing designs?

A: Yes. Both components share identical electrical specifications (400V DC spark-over, 10kA impulse discharge current), mechanical configuration (3-pole through-hole, axial cylinder package), and tolerance (±20%). No circuit redesign is required.

Q: What is the difference between the Tube and Tray packaging formats?

A: Tube and Tray are packaging and delivery formats that do not affect component performance. Tube packaging typically contains fewer units per package, while Tray packaging accommodates higher quantities. Selection depends on procurement volume requirements and handling procedures.

Q: Are both parts compliant with current regulations?

A: Yes. Both the 2036-40-C2LF and 2036-40-B2LF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the 2036-40-C2LF listed as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The 2036-40-B2LF, with identical specifications, is the active equivalent available for new designs and procurement.

Q: Are there any electrical performance differences between these parts?

A: No. Both components have identical voltage ratings, impulse discharge current capacity, tolerance, pole configuration, and fail-short characteristics. Electrical performance is equivalent.
