Bourns 2026-07-A Gas Discharge Tube Equivalent & Substitute Parts
Part Overview
The Bourns 2026-07-A is a 3-pole gas discharge tube (GDT) rated for 75V DC spark-over voltage with 20kA impulse discharge current capacity. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and procurement planning. The 2026-07-A1 serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering current availability.
Substiute Parts
Key Parameters
| Parameter | Value |
|---|---|
| Voltage - DC Spark Over (Nominal) | 75 V |
| Impulse Discharge Current (8/20µs) | 20000A (20kA) |
| Tolerance | ±20% |
| Number of Poles | 3 |
| Fail Short | No |
| Package / Case | Cylinder No Lead, 3 Terminal |
| Series | TRIGARD® 2026 |
Substitute Part Grouping Explanation
The 2026-07-A1 qualifies as a direct substitute based on matching all critical electrical parameters: 75V DC spark-over voltage, 20kA impulse discharge current, ±20% tolerance, 3-pole configuration, and identical mechanical packaging (Cylinder No Lead, 3 Terminal). Both parts belong to the TRIGARD® 2026 series and share the same base product number. The substitution is valid because the electrical performance envelope and physical form factor are identical across both part numbers.

| Product Status | Obsolete | Active |
| Packaging | - | Tube |
Engineering Selection Recommendations
For new designs or system replacements, the 2026-07-A1 is the appropriate selection. This part maintains active product status with current manufacturing support and availability. Both the original 2026-07-A and substitute 2026-07-A1 carry identical RoHS non-compliant and REACH Affected designations, with matching ECCN (EAR99) and HTSUS (8536.30.8000) classifications. The 2026-07-A1 is supplied in Tube packaging, providing standard handling and storage conditions for production environments.
Frequently Asked Questions (FAQ)
Q: Can the 2026-07-A1 be used as a direct replacement for the 2026-07-A?
A: Yes. The 2026-07-A1 is electrically and mechanically identical to the 2026-07-A. Both parts specify 75V DC spark-over voltage, 20kA impulse discharge current, 3-pole configuration, and Cylinder No Lead, 3 Terminal packaging. The substitution is valid for all applications where the original part was specified.
Q: What is the primary difference between these two part numbers?
A: The 2026-07-A is classified as obsolete, while the 2026-07-A1 maintains active product status. The 2026-07-A1 is the current production equivalent with ongoing manufacturer support and availability.
Q: Are there any compliance or certification differences?
A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS code (8536.30.8000).
Q: What packaging options are available?
A: The 2026-07-A1 is supplied in Tube packaging. The original 2026-07-A packaging designation was not specified in available documentation.
