SL1024A600C Equivalent & Substitute Parts

Part Overview

The SL1024A600C is a Gas Discharge Tube (GDT) rated for 600V DC spark-over voltage with 10kA impulse discharge current capacity in a 3-pole configuration. This component is classified as Obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

Gas Discharge Tubes serve as surge protection devices in electrical systems, providing rapid voltage clamping during transient overvoltage events. The obsolete status of the SL1024A600C necessitates evaluation of compatible alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A600C is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 600 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 3
• Package / Case: Cylinder No Lead, 3 Terminal
• Fail Short characteristic: No
• RoHS Status: ROHS3 Compliant

The SL1021A600C meets all specified electrical and mechanical requirements, differing only in product status (Active vs. Obsolete) and packaging format (Tray vs. standard packaging). These differences do not affect functional compatibility or performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A600C is a direct functional equivalent to the SL1024A600C. Both components are manufactured by Littelfuse Inc. and share identical electrical ratings, mechanical configuration, and regulatory compliance certifications.

The primary distinction is product status: the SL1024A600C is classified as Obsolete, while the SL1021A600C maintains Active status. This status difference reflects manufacturing lifecycle positioning and does not indicate performance degradation or incompatibility.

Both parts maintain ROHS3 compliance and identical export classification (EAR99), supporting equivalent regulatory and procurement requirements. The SL1021A600C is the appropriate selection for new designs and ongoing component replenishment where the SL1024A600C is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A600C be used as a direct replacement for the SL1024A600C?

A: Yes. Both components are electrically and mechanically identical, with matching 600V DC spark-over voltage, 10kA impulse discharge current, 3-pole configuration, and package specifications. The SL1021A600C is the active production equivalent.

Q: What is the significance of the Obsolete product status?

A: Obsolete status indicates the SL1024A600C is no longer in active production. The SL1021A600C represents the current production alternative with identical specifications, ensuring continued availability and supply chain continuity.

Q: Are there any differences in RoHS or regulatory compliance?

A: No. Both parts maintain ROHS3 compliance and identical ECCN (EAR99) and HTSUS classifications, supporting equivalent regulatory requirements and export considerations.

Q: Does packaging format affect functional compatibility?

A: No. Packaging format (Tray vs. standard) is a logistics consideration only and does not affect component performance, electrical characteristics, or mechanical fit within the application circuit.

Q: What parameters must remain identical for substitution?

A: Voltage rating (600V), discharge current capacity (10kA), pole count (3), package type (Cylinder No Lead, 3 Terminal), and fail-short characteristic (No) are the critical parameters determining substitution validity.
