Equivalent & Substitute Parts for Bourns 2035-20-C Gas Discharge Tube

Part Overview

The Bourns 2035-20-C is a Gas Discharge Tube (GDT) rated for 200V DC spark-over voltage with 5000A (5kA) impulse discharge current capacity in a 2-pole through-hole configuration. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement. The 2035-20-C maintains electrical and mechanical specifications consistent with the active 2035 series, enabling direct functional replacement where packaging and compliance requirements align.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2035-20-C is based on electrical parameter equivalence within the Bourns 2035 series. The substitute part 2035-20-B maintains identical electrical specifications: 200V DC spark-over voltage, 5000A impulse discharge current, ±15% tolerance, 2-pole configuration, and through-hole axial cylinder packaging. The primary distinction is product status (active versus obsolete) and packaging format (bulk versus standard). Both parts share the same base product number (2035), confirming functional interchangeability for applications requiring these specific electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 2035-20-B is the direct substitute for the obsolete 2035-20-C. Both components are classified as RoHS non-compliant and REACH Affected with identical ECCN designation (EAR99). The 2035-20-B carries active product status, ensuring continued availability and manufacturer support. Selection of the 2035-20-B is appropriate for applications requiring 200V DC spark-over protection with 5kA impulse discharge capacity in through-hole axial cylinder form factor. Compliance requirements remain unchanged between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the 2035-20-B directly replace the 2035-20-C in existing designs?

A: Yes. The 2035-20-B provides electrical and mechanical equivalence to the 2035-20-C. Both components share identical voltage rating (200V DC spark-over), impulse discharge current (5kA), pole configuration (2-pole), mounting type (through-hole), and package form (axial cylinder). The primary difference is product status; the 2035-20-B is active while the 2035-20-C is obsolete.

Q: What is the significance of the packaging difference between these parts?

A: The 2035-20-C is supplied in standard packaging while the 2035-20-B is supplied in bulk packaging. This distinction affects procurement and inventory management but does not alter electrical performance or mechanical compatibility in circuit applications.

Q: Are there compliance considerations when substituting these parts?

A: Both the 2035-20-C and 2035-20-B carry identical compliance designations: RoHS non-compliant, REACH Affected, and ECCN EAR99. No compliance changes result from substitution.

Q: What electrical parameters define substitution eligibility for this GDT series?

A: Substitution within the 2035 series is determined by matching voltage rating (200V DC spark-over), impulse discharge current (5kA), tolerance (±15%), pole count (2), fail-short characteristic (No), and through-hole mounting configuration. The 2035-20-B meets all these criteria.
