Bourns 2026-40-A Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2026-40-A is a 3-pole gas discharge tube (GDT) rated for 400V DC spark-over voltage with 20kA impulse discharge current capacity. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The TRIGARD® 2026 series provides reliable overvoltage protection in multi-pole configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2026-40-A is determined by the following critical parameters:

• Voltage Rating (DC Spark Over): 400V nominal specification
• Impulse Discharge Current: 20kA (8/20µs waveform)
• Pole Configuration: 3-pole requirement
• Fail Mode: Non-shorting characteristic
• Package Type: Cylinder No Lead, 3 Terminal form factor
• Compliance Profile: RoHS non-compliant, REACH Affected status

Substitute parts must maintain equivalence across all these parameters to ensure functional and electrical compatibility within the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

The 2026-40-A1 shares identical manufacturer origin (Bourns Inc.) and series designation (TRIGARD® 2026) with the main part. The substitute maintains equivalent compliance classification (RoHS non-compliant, REACH Affected) and regulatory coding (ECCN: EAR99, HTSUS: 8536.30.8000).

The primary distinction is product status: the 2026-40-A is obsolete while the 2026-40-A1 is active. This status difference indicates ongoing availability and manufacturing support for the 2026-40-A1, making it the appropriate selection for applications requiring current component sourcing.

Electrical parameter equivalence (voltage, current, pole count) cannot be confirmed from the provided data for the 2026-40-A1. Component selection should be validated against complete technical specifications from the manufacturer before implementation.

Frequently Asked Questions (FAQ)

Q: What makes the 2026-40-A1 a suitable substitute for the 2026-40-A?

A: Both components are manufactured by Bourns Inc. within the TRIGARD® 2026 series and share identical compliance and regulatory classifications. The 2026-40-A1 is currently in active production status, addressing the obsolescence of the original part.

Q: Are the electrical ratings identical between these parts?

A: Complete electrical parameter data for the 2026-40-A1 is not provided in the available specifications. Confirmation of voltage rating, discharge current capacity, and pole configuration must be obtained from Bourns Inc. technical documentation.

Q: What is the significance of the "0.85MM LEAD" designation in the 2026-40-A1 description?

A: This designation indicates a specific lead dimension specification. Lead geometry may affect mechanical fit and soldering characteristics in the application circuit. Physical compatibility should be verified against the original mounting requirements.

Q: Can the 2026-40-A1 be used as a direct replacement without circuit modification?

A: Direct replacement feasibility depends on confirmation that all electrical parameters (voltage, current, pole configuration) match the original specification. Mechanical fit verification is also required based on the lead dimension change.

Q: What compliance considerations apply to both parts?

A: Both the 2026-40-A and 2026-40-A1 are RoHS non-compliant and REACH Affected. Applications subject to RoHS or REACH restrictions may require alternative component families. Both parts carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.30.8000).
