Bourns 2026-23-AY Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The Bourns 2026-23-AY is a Gas Discharge Tube (GDT) rated for 230V with 20% tolerance and 20kA surge capacity, configured as a single-pole component. This part is classified as obsolete and is no longer in active production. Due to its obsolete status and non-compliance with RoHS standards, sourcing equivalent or substitute components is necessary for new designs, production continuity, or system upgrades. The 2026-23-AY remains available in limited inventory (825 pcs) but should be replaced with active alternatives for long-term reliability and regulatory compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2026-23-AY is determined by the following critical electrical and mechanical parameters:

• Voltage Rating: 230V nominal operating voltage
• Surge Current Capacity: 20kA minimum surge handling capability
• Configuration: Single-pole gas discharge tube architecture
• Manufacturer Compatibility: Bourns Inc. product line ensures mechanical and electrical consistency

The substitute part 2026-23-A1 meets these core substitution criteria. Both components are manufactured by Bourns Inc. and share identical voltage and surge specifications. The primary distinction lies in product status and compliance posture: the 2026-23-A1 is active in production and carries EAR99 export classification, whereas the 2026-23-AY is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 2026-23-A1 is the appropriate substitute for the 2026-23-AY based on the following factors:

• Product Status: The 2026-23-A1 maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete 2026-23-AY.
• Electrical Equivalence: Both components share identical 230V voltage rating and single-pole configuration, confirming functional compatibility in circuit applications.
• Compliance and Export: The 2026-23-A1 carries EAR99 classification, providing clearer export and regulatory documentation compared to the OBSOLETE designation of the 2026-23-AY. Both remain non-compliant with RoHS and are REACH Affected.
• Inventory Availability: The 2026-23-A1 has higher current stock (1066 pcs) relative to the 2026-23-AY (825 pcs), supporting procurement reliability.

For new designs or production transitions, the 2026-23-A1 is the recommended selection. For legacy system maintenance where the 2026-23-AY must be retained, the 2026-23-A1 serves as a direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can the 2026-23-A1 directly replace the 2026-23-AY in existing circuits?

A: Yes. Both components are single-pole gas discharge tubes rated for 230V operation from Bourns Inc. They share identical voltage and configuration specifications, confirming direct functional substitution in circuit applications.

Q: What is the primary reason to transition from 2026-23-AY to 2026-23-A1?

A: The 2026-23-AY is classified as obsolete and no longer in active production. The 2026-23-A1 is an active product with ongoing manufacturing support, ensuring supply chain continuity and regulatory documentation clarity.

Q: Are there any compliance differences between these parts?

A: Both components are RoHS non-compliant and REACH Affected. The 2026-23-A1 carries EAR99 export classification, whereas the 2026-23-AY is marked OBSOLETE. For applications requiring RoHS compliance, neither part is suitable.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by voltage rating (230V), surge current capacity (20kA), and single-pole configuration. Both the 2026-23-AY and 2026-23-A1 meet these criteria, confirming their equivalence.

Q: Is the lead specification difference between these parts significant?

A: The 2026-23-A1 specifies 0.85MM lead dimensions. This represents a mechanical packaging detail. Confirm lead compatibility with your PCB footprint and assembly process before implementation.

Q: Which part should be selected for new designs?

A: The 2026-23-A1 should be selected for new designs due to its active production status, higher inventory availability, and clearer regulatory classification.
