Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A300C is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 300 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
• Moisture Sensitivity Level: 1 (Unlimited)

The SL1021A300C meets all these criteria and is classified as Active, making it a direct functional equivalent for the obsolete SL1024A300C.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A300C is the direct substitute for the obsolete SL1024A300C. Both components are manufactured by Littelfuse and share identical electrical and mechanical specifications across all critical parameters. The SL1021A300C carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, confirming compatibility in regulated environments. The SL1021A300C is supplied in Tray packaging, whereas the SL1024A300C packaging designation was not specified; this represents the only operational difference between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A300C directly replace the SL1024A300C in existing designs?

A: Yes. Both components share identical voltage ratings (300V DC spark-over), discharge current capacity (10kA), pole configuration (3-pole), package type (Cylinder No Lead, 3 Terminal), and fail-short characteristics. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The SL1024A300C is classified as Obsolete. The SL1021A300C is an Active equivalent part from the same manufacturer, ensuring continued procurement and supply availability.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant with identical Moisture Sensitivity Level ratings (MSL 1 - Unlimited), confirming equivalence in regulated applications.

Q: Does packaging differ between these parts?

A: The SL1024A300C packaging was not specified in available documentation. The SL1021A300C is supplied in Tray packaging. This represents a supply-chain consideration only and does not affect electrical or mechanical performance.

Q: Are both parts suitable for 300V surge protection applications?

A: Yes. Both the SL1024A300C and SL1021A300C are rated for 300V DC spark-over voltage with 10kA impulse discharge current capacity, making them suitable for identical surge protection circuit applications.
