Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A230C is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 230 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 3
• Package / Case: Cylinder No Lead, 3 Terminal
• Fail Short Characteristic: No

The SL1021A230C qualifies as a direct substitute based on matching all critical parameters. While the SL1021A230C belongs to a different series (SL1021A versus SL1024A) and carries Active product status, it maintains identical electrical ratings and mechanical form factor, ensuring functional compatibility in applications currently utilizing the obsolete SL1024A230C.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A230C is the qualified substitute for the obsolete SL1024A230C. Selection of the SL1021A230C is supported by:

• Identical electrical performance: 230V DC spark-over voltage and 10kA impulse discharge current capacity
• Matching mechanical form factor: Cylinder No Lead, 3 Terminal package
• Equivalent regulatory compliance: Both parts maintain ROHS3 compliance and unlimited MSL rating
• Active product status: The SL1021A230C is currently in active production, ensuring long-term availability and supply chain continuity

For applications currently deployed with the SL1024A230C, direct replacement with the SL1021A230C requires no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A230C be used as a direct replacement for the SL1024A230C?

A: Yes. Both parts share identical electrical ratings (230V spark-over, 10kA discharge current), pole configuration (3-pole), and mechanical package (Cylinder No Lead, 3 Terminal). No circuit modifications are required.

Q: Why are the series designations different (SL1024A versus SL1021A)?

A: Series designation reflects internal Littelfuse product line organization. The SL1021A represents a current-generation equivalent within the same product family, offering the same functional performance as the obsolete SL1024A series.

Q: Are there compliance differences between these parts?

A: No. Both the SL1024A230C and SL1021A230C maintain ROHS3 compliance, unlimited MSL rating, and identical ECCN and HTSUS classifications.

Q: What is the difference in packaging between these parts?

A: The SL1024A230C packaging is listed as unspecified (-), while the SL1021A230C is supplied in Tray packaging. This represents a packaging format difference only and does not affect electrical or mechanical compatibility.

Q: Is the SL1021A230C available in inventory?

A: Yes. The SL1021A230C is classified as Active product status with 962 pieces in new original stock, ensuring availability for immediate procurement.
