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

Part Overview

The Bourns 2026-23-ALF is a Gas Discharge Tube (GDT) rated for 230 V DC spark-over voltage with 20 kA impulse discharge current capacity in a 3-pole configuration. This component is classified as Obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement.

Gas Discharge Tubes function as surge protection devices, conducting high-energy transients to ground while remaining non-conductive under normal operating conditions. The obsolete status of the 2026-23-ALF necessitates sourcing equivalent alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2026-23-ALF is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 230 V
• Impulse Discharge Current (8/20µs): 20000 A (20 kA)
• Tolerance: ±20%
• Number of Poles: 3
• Fail Short characteristic: No
• Package / Case: Cylinder No Lead, 3 Terminal
• Series: TRIGARD® 2026
• RoHS Status: ROHS3 Compliant

The substitute part 2026-23-A1LF meets all these criteria and is therefore electrically and mechanically interchangeable with the 2026-23-ALF.

Parameter Comparison

Engineering Selection Recommendations

The 2026-23-A1LF is the direct equivalent substitute for the obsolete 2026-23-ALF. Both components are manufactured by Bourns Inc. within the TRIGARD® 2026 series and share identical electrical specifications and mechanical form factors.

The primary distinction is product status: the 2026-23-A1LF maintains Active status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and equivalent regulatory certifications (REACH Unaffected, ECCN EAR99).

For new designs or component replacement in existing systems, the 2026-23-A1LF is the appropriate selection due to its active production status and guaranteed long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the 2026-23-A1LF be used as a direct replacement for the 2026-23-ALF?

A: Yes. Both components are electrically and mechanically identical, with matching voltage ratings (230 V DC spark-over), discharge current capacity (20 kA), pole configuration (3-pole), and physical packaging (Cylinder No Lead, 3 Terminal).

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The 2026-23-ALF is Obsolete, while the 2026-23-A1LF is Active. The 2026-23-A1LF is the current production equivalent and is recommended for all new applications and replacements.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance status and regulatory certifications (REACH Unaffected, ECCN EAR99).

Q: What does the packaging designation mean?

A: The 2026-23-ALF uses a standard packaging designation, while the 2026-23-A1LF is supplied in Bulk packaging. Both maintain the same physical form factor (Cylinder No Lead, 3 Terminal) and are functionally interchangeable.

Q: Are there inventory considerations for component selection?

A: The 2026-23-A1LF has confirmed active inventory (836 Pcs New Original In Stock) and ongoing production support. The 2026-23-ALF, being obsolete, has limited remaining inventory (1039 Pcs) with no future manufacturing planned.
