SL1024A300RF Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The SL1024A300RF is a 3-pole gas discharge tube (GDT) rated for 300V 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 SL1024A300RF is classified as obsolete. Locating active equivalent models is necessary to ensure long-term supply chain continuity and access to current manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A300RF is based on electrical and mechanical parameter equivalence:

Critical Matching Parameters:

• Voltage - DC Spark Over (Nominal): 300 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 3
• Fail Short: Yes
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)

The SL1021A300RF meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete SL1024A300RF.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A300RF is the direct substitute for the SL1024A300RF. Both components are manufactured by Littelfuse Inc. and share identical electrical specifications, mechanical configuration, and regulatory compliance status.

The primary advantage of selecting the SL1021A300RF is its active product status, ensuring ongoing availability, manufacturing support, and compliance with current industry standards. Both parts maintain ROHS3 compliance and carry identical export classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the SL1021A300RF be used as a direct replacement for the SL1024A300RF?

A: Yes. Both components have identical voltage ratings (300V DC spark-over), discharge current capacity (10kA), pole configuration (3-pole), mounting type (through-hole), and package geometry (axial cylinder, 3-lead radial bend). Electrical and mechanical compatibility is complete.

Q: What is the difference between the SL1024A and SL1021A series?

A: The SL1024A series is obsolete, while the SL1021A series is active. Both series share the same electrical and mechanical specifications for equivalent voltage and current ratings. The series designation change reflects manufacturing evolution within the Littelfuse product line.

Q: Are there any packaging differences between these parts?

A: The SL1024A300RF is supplied in standard packaging, while the SL1021A300RF is supplied in tray packaging. Both use identical component geometry and lead configuration, so they are mechanically interchangeable in through-hole applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SL1024A300RF and SL1021A300RF are ROHS3 compliant, carry MSL rating of 1 (unlimited moisture sensitivity), and share the same ECCN (EAR99) and HTSUS classification (8536.30.8000).

Q: Why should I transition from SL1024A300RF to SL1021A300RF?

A: The SL1024A300RF is obsolete and subject to supply discontinuation. The SL1021A300RF is an active product with guaranteed long-term availability and manufacturing support from Littelfuse Inc., making it the recommended choice for new designs and ongoing production.
