Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A600RG 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
• Fail Short characteristic: Yes
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• RoHS Compliance: ROHS3 Compliant

The SL1021A600RF meets all substitution criteria. While the SL1024A600RG is obsolete and the SL1021A600RF is active, both components share identical electrical ratings, mechanical configuration, and regulatory compliance status, making them functionally interchangeable for the specified application.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A600RF is the direct substitute for the obsolete SL1024A600RG. Both components are manufactured by Littelfuse Inc. and maintain identical electrical performance specifications, mechanical form factor, and regulatory compliance certifications.

The SL1021A600RF carries active product status, ensuring ongoing availability and manufacturer support. Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Selection of the SL1021A600RF eliminates obsolescence risk while preserving full functional compatibility with existing circuit designs and PCB layouts.
