SL1024A600R Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The SL1024A600R is a 3-pole gas discharge tube (GDT) rated for 600V 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 industrial and telecommunications applications.

The SL1024A600R is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A600R is based on strict equivalence of electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - DC Spark Over (Nominal): 600 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 3
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• Fail Short Characteristic: No

The SL1021A600R meets all critical electrical and mechanical requirements for direct substitution. Both parts share identical voltage ratings, current capacity, pole configuration, mounting method, and package geometry. The substitute maintains equivalent environmental compliance (ROHS3, MSL 1) and regulatory classification (EAR99, HTSUS 8536.30.8000).

Parameter Comparison

Engineering Selection Recommendations

The SL1021A600R is the direct equivalent substitute for the obsolete SL1024A600R. Both components are manufactured by Littelfuse and provide identical electrical performance and mechanical compatibility.

Selection Basis:

The SL1021A600R offers the advantage of active product status, ensuring continued availability and supply chain support. Both parts maintain equivalent compliance certifications (ROHS3, EAR99) and regulatory classifications. The substitute is available in tray packaging, supporting production and inventory management requirements.

For applications currently using the SL1024A600R, direct replacement with the SL1021A600R requires no circuit redesign or application modification. Pin configuration, mounting footprint, and electrical characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A600R be used as a direct replacement for the SL1024A600R?

A: Yes. Both components share identical electrical ratings (600V DC spark-over, 10kA impulse discharge current), pole configuration (3-pole), mounting method (through-hole), and package geometry (axial cylinder, 3-lead radial bend). No circuit modification is required.
