SL1024A260RF Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The SL1024A260RF is a 3-pole gas discharge tube (GDT) rated for 260V DC spark-over voltage with 10kA impulse discharge current capacity. Designed for through-hole mounting in axial cylinder configuration, this component is used for overvoltage protection in telecommunications, power supply, and industrial control applications.

The SL1024A260RF 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 SL1024A260RF is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 260 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

The SL1021A260RF meets all substitution criteria. Both parts are manufactured by Littelfuse Inc., share identical electrical ratings, mechanical configuration, and environmental compliance certifications. The primary distinction is product status: SL1024A260RF is obsolete, while SL1021A260RF is active production.

Parameter Comparison

Engineering Selection Recommendations

For new designs or ongoing production requiring 260V, 10kA, 3-pole gas discharge tube protection, the SL1021A260RF is the appropriate selection. This part maintains active production status with Littelfuse Inc., ensuring long-term supply chain availability and consistent manufacturing quality.

For field replacement or retrofit applications where the SL1024A260RF was originally specified, the SL1021A260RF provides direct functional equivalence. Both parts carry ROHS3 compliance and identical electrical performance characteristics, supporting seamless integration into existing circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A260RF directly replace the SL1024A260RF in existing designs?

A: Yes. Both parts share identical electrical ratings (260V spark-over, 10kA impulse current), mechanical configuration (3-pole through-hole axial cylinder), and environmental compliance. No circuit redesign is required.

Q: What is the difference between the SL1024A260RF and SL1021A260RF?

A: The primary difference is product status. The SL1024A260RF is obsolete, while the SL1021A260RF is in active production. Electrical and mechanical specifications are equivalent.

Q: Are there packaging differences between these parts?

A: The SL1024A260RF is supplied in standard packaging, while the SL1021A260RF is supplied in tray packaging. Both use identical axial cylinder, 3-lead radial bend case configuration suitable for through-hole mounting.

Q: Do both parts meet current RoHS requirements?

A: Yes. Both the SL1024A260RF and SL1021A260RF are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be specified for new procurement?

A: The SL1021A260RF should be specified for new designs and ongoing production due to its active product status and assured supply availability from Littelfuse Inc.
