Bourns 2026-47-A Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2026-47-A is a 3-pole gas discharge tube (GDT) rated for 470V 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 2026-47-A is determined by the following critical parameters:

• Voltage Rating (DC Spark Over): 470V 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 compatibility in existing circuit designs and protection schemes.

Parameter Comparison

Engineering Selection Recommendations

The 2026-47-A1 shares the same manufacturer (Bourns Inc.), series designation (TRIGARD® 2026), and voltage rating (470V) as the obsolete 2026-47-A. The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain identical RoHS non-compliant and REACH Affected compliance profiles, with matching ECCN and HTSUS classifications.

The primary distinction is the transition from Obsolete to Active status, which supports long-term procurement reliability. Compliance and regulatory classifications remain consistent between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the 2026-47-A1 directly replace the 2026-47-A in existing designs?

A: Both parts are manufactured by Bourns Inc. within the TRIGARD® 2026 series and share the 470V DC spark-over rating. The 2026-47-A1 carries Active product status, whereas the 2026-47-A is Obsolete. Compliance profiles (RoHS non-compliant, REACH Affected) are identical. Detailed electrical specifications for the 2026-47-A1 should be cross-referenced with design requirements.

Q: What is the significance of the Obsolete status for the 2026-47-A?

A: Obsolete classification indicates the part is no longer in active production. Identifying active substitute parts ensures continued availability for maintenance, repairs, and new implementations. The 2026-47-A1 provides an active alternative within the same product family.

Q: Are there differences in the package or terminal configuration between these parts?

A: The 2026-47-A specifies Cylinder No Lead, 3 Terminal packaging. The 2026-47-A1 description references 0.85MM lead specification. Physical form factor compatibility should be confirmed against specific application requirements and PCB layouts.

Q: Do both parts share the same regulatory and compliance status?

A: Yes. Both the 2026-47-A and 2026-47-A1 are RoHS non-compliant and REACH Affected, with identical ECCN (EAR99) and HTSUS (8536.30.8000) classifications.
