Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024B090C is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - DC Spark Over (Nom): 90 V
• Impulse Discharge Current (8/20µs): 20000A (20kA)
• Number of Poles: 3
• Package / Case: Cylinder No Lead, 3 Terminal
• Fail Short: No
• Mounting Type: User Defined

The SL1021B090C qualifies as a direct substitute based on identical values across all critical parameters. The primary distinction is product status: SL1021B090C is Active, whereas SL1024B090C is Obsolete. Both components share identical electrical ratings, mechanical configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SL1021B090C is the qualified substitute for the obsolete SL1024B090C. Both components are manufactured by Littelfuse Inc. and maintain identical electrical performance specifications, mechanical form factor, and regulatory compliance status (ROHS3 Compliant). The SL1021B090C carries Active product status, ensuring continued availability and manufacturer support. Selection of SL1021B090C eliminates obsolescence risk while preserving full functional equivalence in surge protection applications requiring 90V spark-over and 20kA impulse discharge capacity.

Frequently Asked Questions (FAQ)

Q: Can SL1021B090C be used as a direct replacement for SL1024B090C?

A: Yes. Both components share identical electrical ratings (90V spark-over, 20kA impulse discharge), mechanical configuration (3-pole, cylinder no-lead package), and compliance certifications. The SL1021B090C is the active production equivalent.

Q: What is the primary difference between these two parts?

A: Product status. SL1024B090C is Obsolete; SL1021B090C is Active. All electrical and mechanical parameters are identical.

Q: Are there packaging differences?

A: The SL1024B090C packaging is listed as "-" (unspecified). The SL1021B090C is supplied in Tray packaging. Both use the same Cylinder No Lead, 3 Terminal case style.

Q: Do both parts meet RoHS requirements?

A: Yes. Both SL1024B090C and SL1021B090C are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why should I transition from SL1024B090C to SL1021B090C?

A: The SL1024B090C is Obsolete, creating long-term supply and support risk. The SL1021B090C provides identical performance with Active status and ongoing manufacturer availability.
