Bourns 2028-23-C2LF Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The Bourns 2028-23-C2LF is a 3-pole gas discharge tube (GDT) rated for 230V DC spark-over voltage with 20kA impulse discharge current capacity. This component is designed for through-hole mounting in axial cylinder configuration with radial bend leads. The 2028-23-C2LF is currently listed as obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2028-23-C2LF is determined by matching the following critical electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 230 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 substitute part 2026-23-C2LF meets all specified parameters and represents an active product alternative within the Bourns TRIGARD® 2026 series.

Parameter Comparison

Engineering Selection Recommendations

The 2026-23-C2LF serves as the direct substitute for the obsolete 2028-23-C2LF. Both components share identical electrical specifications (230V spark-over, 20kA impulse discharge current) and mechanical configuration (3-pole through-hole axial cylinder package). The 2026-23-C2LF maintains active product status within the Bourns TRIGARD® 2026 series and carries equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99). Selection of the 2026-23-C2LF eliminates obsolescence risk while preserving full functional compatibility in circuit protection applications requiring 230V three-pole gas discharge tube performance.

Frequently Asked Questions (FAQ)

Q: Can the 2026-23-C2LF directly replace the 2028-23-C2LF in existing designs?

A: Yes. Both components share identical electrical ratings (230V spark-over, 20kA impulse discharge current, ±20% tolerance), pole configuration (3-pole), and mechanical package (axial cylinder, 3-lead radial bend through-hole mounting). No circuit modifications are required.

Q: What is the difference between the 2028 and 2026 series?

A: The 2028 series is obsolete. The 2026 series (TRIGARD® 2026) represents the active product line from Bourns Inc. with equivalent electrical and mechanical specifications for this voltage and current rating.

Q: Are there packaging differences between these parts?

A: The main part (2028-23-C2LF) is supplied in standard packaging, while the substitute (2026-23-C2LF) is supplied in tray packaging. Both maintain the same axial cylinder, 3-lead radial bend through-hole component form factor.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 2028-23-C2LF and 2026-23-C2LF are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.30.8000.

Q: What is the impulse discharge current specification?

A: Both components are rated for 20000A (20kA) impulse discharge current at 8/20 microsecond waveform, with ±20% tolerance.
