Bourns 2028-35-C2LF Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2028-35-C2LF is a 3-pole gas discharge tube (GDT) rated for 350V DC spark-over voltage with 20kA impulse discharge current capacity. This component is designed for overvoltage protection in through-hole applications with axial cylinder configuration and radial lead bending. The 2028-35-C2LF is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2028-35-C2LF is determined by matching the following critical electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 350 V
• Impulse Discharge Current (8/20µs): 20000A (20kA)
• Tolerance: ±20%
• Number of Poles: 3
• Fail Short characteristic: No
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)

The Bourns 2026-35-C2LF meets all specified electrical and mechanical requirements and qualifies as a direct substitute. The primary distinction is product status: the 2028 series is obsolete while the 2026 series (TRIGARD® 2026) maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 2026-35-C2LF is the appropriate substitute for the obsolete 2028-35-C2LF. Both components share identical electrical specifications (350V spark-over, 20kA impulse current) and mechanical configuration (3-pole through-hole, axial cylinder package). The 2026 series maintains active production status and full compliance with ROHS3, REACH, and export control requirements (EAR99). Selection of the 2026-35-C2LF ensures design continuity with equivalent performance characteristics and sustained supply availability.

Frequently Asked Questions (FAQ)

Q: Can the 2026-35-C2LF be used as a direct replacement for the 2028-35-C2LF?

A: Yes. Both components meet identical electrical and mechanical specifications: 350V DC spark-over voltage, 20kA impulse discharge current, 3-pole configuration, and through-hole axial cylinder package with radial leads. The 2026 series is the active production equivalent.

Q: What is the primary reason for substitution?

A: The 2028-35-C2LF is classified as obsolete. The 2026-35-C2LF provides equivalent functionality with active product status and ongoing manufacturing support.

Q: Are there packaging differences between these parts?

A: The main part (2028-35-C2LF) is supplied in standard packaging, while the substitute (2026-35-C2LF) is supplied in tray packaging. Both maintain identical component specifications and through-hole mounting configuration.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 2028-35-C2LF and 2026-35-C2LF are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.30.8000.

Q: What are the critical parameters for substitution eligibility?

A: Substitution requires matching voltage rating (350V), impulse current capacity (20kA), pole count (3), fail-short characteristic (No), mounting type (through-hole), and package configuration (axial cylinder with radial leads).
