SL1024A500RF Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The SL1024A500RF is a 3-pole gas discharge tube (GDT) rated for 500V DC spark-over voltage with 10kA impulse discharge current capacity. Designed for through-hole mounting in axial cylinder configuration, this component is used for transient overvoltage protection in telecommunications and industrial applications.

The SL1024A500RF is classified as obsolete. Identifying qualified substitute parts ensures design continuity and maintains supply chain reliability for applications requiring equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A500RF is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 500 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 3
• Fail Short characteristic: Yes
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SL1021A500RF meets all substitution criteria and is qualified as a direct equivalent for the obsolete SL1024A500RF.

Parameter Comparison
