Substitute Part Grouping Explanation

Substitution for the SL1024B350C is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 350 V
• Impulse Discharge Current (8/20µs): 20000A (20kA)
• Number of Poles: 3
• Package / Case: Cylinder No Lead, 3 Terminal
• Fail Short characteristic: No

The SL1021B350C meets all substitution criteria. Both components are manufactured by Littelfuse Inc., share identical electrical ratings, pole configuration, and physical packaging. The primary distinction is product status: SL1021B350C is active and available, whereas SL1024B350C is obsolete.
