Bourns 2035-60-B Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2035-60-B is a 2-pole gas discharge tube (GDT) rated for 600V DC spark-over voltage with 5000A (5kA) impulse discharge current capacity. This component is designed for through-hole mounting in axial cylinder configuration and is currently in active production status. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize inventory management, and maintain design continuity when the primary part becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution of the Bourns 2035-60-B is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 600 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 CG5600L meets all these substitution criteria. Both parts are functionally equivalent gas discharge tubes with identical electrical ratings and mechanical form factors. Substitution is valid when these parameters align exactly across the main part and candidate substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 2035-60-B and Littelfuse CG5600L are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Compliance Requirements: The Littelfuse CG5600L offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental and regulatory requirements. The Bourns 2035-60-B is RoHS non-compliant and REACH affected, which may restrict its use in certain markets or applications.

Packaging Considerations: The Bourns part is supplied in bulk packaging, while the Littelfuse part is supplied in cut tape format. Packaging selection depends on assembly process requirements and inventory management practices.

Supply Chain: Both parts are in active production with confirmed inventory availability, ensuring continuity of supply for either selection.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse CG5600L directly replace the Bourns 2035-60-B in existing designs?

A: Yes. Both parts share identical electrical ratings (600V DC spark-over, 5000A impulse discharge current), identical pole configuration (2-pole), and identical mechanical form factor (through-hole axial cylinder). Direct substitution is electrically and mechanically valid.

Q: What is the difference in tolerance specifications between these parts?

A: The Bourns 2035-60-B specifies ±15% tolerance on spark-over voltage. The Littelfuse CG5600L does not provide a published tolerance specification in the available data. Design validation should confirm whether this difference affects circuit performance requirements.

Q: Are there packaging implications for using the Littelfuse substitute?

A: Yes. The Bourns part is supplied in bulk packaging, while the Littelfuse part is supplied in cut tape format. Assembly processes optimized for bulk components may require adjustment for cut tape handling. Inventory management and component feeding systems should be evaluated accordingly.

Q: Which part should be selected for new designs?

A: Selection should prioritize application compliance requirements. For designs requiring RoHS3 compliance or REACH unaffected status, the Littelfuse CG5600L is the appropriate choice. For applications without these regulatory constraints, either part is functionally equivalent.

Q: Are both parts currently available?

A: Yes. The Bourns 2035-60-B has 900 pieces in stock, and the Littelfuse CG5600L has 2821 pieces in stock, both listed as new original inventory.
