Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A230CF 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
• Fail Short characteristic: Yes
• Package / Case: Cylinder No Lead, 3 Terminal
• Mounting Type: User Defined

The substitute part SL1021A230CF meets all these criteria and is manufactured by the same supplier (Littelfuse Inc.), ensuring functional and mechanical compatibility. The primary distinction is product status: SL1021A230CF is active and available, whereas SL1024A230CF is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A230CF is the direct substitute for the obsolete SL1024A230CF. Both components share identical electrical ratings (230V spark-over, 10kA impulse discharge current), mechanical configuration (3-pole, cylinder no-lead package), and regulatory compliance (ROHS3 Compliant). The SL1021A230CF is currently in active production status with confirmed inventory availability, making it the appropriate selection for new designs, production continuity, and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A230CF be used as a direct replacement for the SL1024A230CF?

A: Yes. Both components are electrically and mechanically equivalent across all critical parameters: 230V DC spark-over voltage, 10kA impulse discharge current, 3-pole configuration, and identical package type. The SL1021A230CF is the active production equivalent.

Q: What is the difference between the SL1024A230CF and SL1021A230CF?
