SL1024A260RG Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The SL1024A260RG 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 classified as obsolete. Due to its obsolete status, identifying active equivalent parts is essential for ongoing design support, maintenance, and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A260RG is determined by strict equivalence across the following critical parameters:

• Voltage Rating: 260V DC spark-over voltage (nominal)
• Discharge Current: 10kA impulse discharge current (8/20µs waveform)
• Pole Configuration: 3-pole architecture
• Fail Mode: Short-circuit failure characteristic
• Mounting and Package: Through-hole axial cylinder with 3 radial leads
• Compliance: ROHS3 compliance and MSL rating

The identified substitute maintains identical electrical performance specifications and mechanical compatibility with the original part, with the primary distinction being product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A260RF is a direct functional equivalent to the SL1024A260RG. Both components are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters. The primary advantage of the SL1021A260RF is its active product status, ensuring ongoing availability and supply chain continuity.

Both parts maintain ROHS3 compliance and carry identical export classification (EAR99) and tariff codes (HTSUS 8536.30.8000). The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either component.

Selection between these parts should be based on supply availability and procurement lead times, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A260RF be used as a direct replacement for the SL1024A260RG?

A: Yes. Both components share identical voltage ratings (260V DC spark-over), discharge current capacity (10kA), pole configuration (3-pole), fail-short characteristic, mounting type (through-hole), and package geometry (axial cylinder with 3 radial leads). Electrical and mechanical compatibility is complete.

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

A: The series designation reflects different product generations within the Littelfuse GDT portfolio. The SL1021A series represents the current active product line, while the SL1024A series is obsolete. Electrical performance and mechanical specifications are equivalent for the 260V 10kA 3-pole configuration.

Q: Are there any packaging differences between these parts?

A: The SL1024A260RG is supplied without specified packaging, while the SL1021A260RF is supplied in tray packaging. Both components use identical axial cylinder, 3-lead radial-bend package geometry suitable for through-hole PCB mounting.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SL1024A260RG and SL1021A260RF are ROHS3 compliant, carry MSL rating 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8536.30.8000) classifications.

Q: Why is the SL1024A260RG listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The SL1021A260RF represents the current equivalent offering from Littelfuse Inc. for this electrical specification.
