Key Parameters

Substitute Part Grouping Explanation

The Bourns 2026-23-CLF qualifies as a direct substitute for the 2028-23-CLF based on matching electrical and mechanical specifications. Substitution eligibility is determined by the following criteria:

• Voltage - DC Spark Over (Nominal): 230 V
• Impulse Discharge Current (8/20µs): 20000A (20kA)
• Tolerance: ±20%
• Number of Poles: 3
• Fail Short: No
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (T-Shape)

The 2026-23-CLF maintains all critical electrical parameters and physical form factor compatibility, enabling direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 2026-23-CLF be used as a direct replacement for the 2028-23-CLF?

A: Yes. Both components share identical electrical specifications (230V DC spark-over, 20kA impulse discharge current, ±20% tolerance, 3-pole configuration) and identical physical packaging (Axial Cylinder, 3 Lead T-Shape through-hole mount). No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The 2028-23-CLF is obsolete, while the 2026-23-CLF is an active product from the TRIGARD® 2026 series. The 2026-23-CLF represents the current manufacturing equivalent with ongoing supply availability.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification. Regulatory requirements are satisfied by either component.

Q: Does the packaging format affect substitution?

A: The 2028-23-CLF original packaging is not specified in available data. The 2026-23-CLF is supplied in bulk packaging. The electrical and mechanical specifications remain unchanged regardless of packaging format.

Q: Are there any performance differences in overvoltage protection?

A: No. Both components provide identical overvoltage protection performance with matching spark-over voltage, discharge current capacity, and fail-short characteristics.
