Bourns 2035-42-C Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2035-42-C is a 2-pole gas discharge tube (GDT) rated for 420V 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 used for overvoltage protection in electronic circuits.

The 2035-42-C is classified as obsolete. Locating active equivalent parts is necessary to ensure continued availability for new designs and maintenance applications. The substitute part identified maintains identical electrical and mechanical specifications while offering active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2035-42-C is determined by the following critical parameters:

• Voltage - DC Spark Over (Nominal): 420 V
• Impulse Discharge Current (8/20µs): 5000A (5kA)
• Tolerance: ±15%
• Number of Poles: 2
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder
• Fail Short: No

The substitute part 2035-42-B matches all of these parameters exactly. Both parts belong to the Bourns 2035 series and share identical electrical ratings and mechanical form factors, making them functionally interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 2035-42-B is the direct substitute for the obsolete 2035-42-C. Both parts are manufactured by Bourns Inc. and carry identical electrical specifications and mechanical form factors. The primary distinction is product status: the 2035-42-B maintains active availability, whereas the 2035-42-C is obsolete.

Both parts share the same regulatory compliance profile (RoHS non-compliant, REACH Affected). Selection between these parts should be based on availability and supply chain requirements rather than technical performance, as they are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 2035-42-B directly replace the 2035-42-C in existing designs?

A: Yes. The 2035-42-B is electrically and mechanically identical to the 2035-42-C. Both parts have the same 420V DC spark-over voltage, 5000A impulse discharge current, 2-pole configuration, through-hole mounting, and axial cylinder package. Direct substitution is possible without circuit modification.

Q: Why is the 2035-42-C listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The 2035-42-B provides equivalent functionality and is the recommended active alternative for new designs and ongoing supply.

Q: Are there any compliance differences between these parts?

A: No. Both the 2035-42-C and 2035-42-B share identical RoHS and REACH compliance status. Both are RoHS non-compliant and REACH Affected.

Q: What is the tolerance specification for spark-over voltage?

A: Both parts have a ±15% tolerance on the 420V nominal DC spark-over voltage specification.

Q: Are these parts suitable for surface-mount applications?

A: No. Both the 2035-42-C and 2035-42-B are through-hole mounted components in axial cylinder packages. They are not designed for surface-mount assembly.
