Bourns 2035-23-B Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2035-23-B is a Gas Discharge Tube (GDT) rated for 230V DC spark-over voltage with 5000A (5kA) impulse discharge current capacity in a 2-pole through-hole configuration. This component is designed for overvoltage protection applications requiring fast transient suppression. The part is currently active in production. Substitute parts may be required due to inventory availability, packaging preferences, or specific compliance requirements for end-application deployment.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 2035-23-B is determined by the following critical parameters:

• Voltage - DC Spark Over (Nominal): 230 V
• Impulse Discharge Current (8/20µs): 5000A (5kA)
• Number of Poles: 2
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder
• Fail Short Characteristic: No

The Littelfuse CG5230L meets all electrical and mechanical substitution criteria. Both components share identical spark-over voltage, impulse discharge current rating, pole configuration, mounting type, and package form factor. Differences in packaging format (bulk versus cut tape) and compliance certifications do not affect functional interchangeability in the circuit application.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 2035-23-B and Littelfuse CG5230L are active production components with identical electrical performance specifications. Selection between these parts should be based on:

• Packaging format requirements: The Bourns part is supplied in bulk packaging, while the Littelfuse part is supplied in cut tape format. Choose based on assembly process and quantity requirements.
• Compliance requirements: The Littelfuse CG5230L carries ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental compliance mandates. The Bourns part is RoHS non-compliant and REACH affected.
• Inventory and lead time: Both parts are in active stock. Selection may depend on supplier availability and delivery schedules.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse CG5230L directly replace the Bourns 2035-23-B in existing designs?

A: Yes. Both components share identical electrical ratings (230V spark-over, 5kA impulse discharge current), pole configuration (2-pole), mounting type (through-hole), and package form factor (axial cylinder). No circuit redesign is required.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging is supplied as loose components suitable for manual assembly or small-volume applications. Cut tape packaging is pre-formatted on carrier tape for automated pick-and-place assembly equipment. The choice depends on manufacturing process requirements.

Q: Does the tolerance difference (±15% for Bourns versus no specified tolerance for Littelfuse) affect substitution?

A: Tolerance specifications define the acceptable variation range for the spark-over voltage. Both parts are designed to operate at 230V nominal. The absence of a stated tolerance for the Littelfuse part does not indicate inferior performance; it reflects different manufacturer specification practices. Both are suitable for the same application.

Q: Are there compliance implications when switching from the Bourns to the Littelfuse part?

A: Yes. The Littelfuse CG5230L is ROHS3 compliant and REACH unaffected, while the Bourns 2035-23-B is RoHS non-compliant and REACH affected. If your end application or market requires RoHS or REACH compliance, the Littelfuse part is the appropriate choice.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both parts are active production components from established manufacturers. Selection should be based on your specific reliability requirements, compliance certifications needed, and supply chain preferences. Consult application-specific design documentation for any additional qualification requirements.
