Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A090C is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 90V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 3
• Fail Short characteristic: No
• Package / Case: Cylinder No Lead, 3 Terminal
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The SL1021A090C meets all specified parameters and is classified as Active, making it a direct functional equivalent for the obsolete SL1024A090C.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A090C is the direct substitute for the SL1024A090C. Both parts are manufactured by Littelfuse and share identical electrical ratings (90V spark-over, 10kA impulse discharge current) and mechanical specifications (3-pole, cylinder no-lead package). The SL1021A090C carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental requirements. The primary distinction is packaging format: SL1024A090C uses user-defined packaging while SL1021A090C is supplied in trays. Selection between these parts should be based on procurement requirements and packaging compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A090C be used as a direct replacement for the SL1024A090C?

A: Yes. Both parts are identical in electrical performance (90V spark-over, 10kA impulse discharge current) and mechanical configuration (3-pole, cylinder no-lead package). The SL1021A090C is the active equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is product status and packaging. The SL1024A090C is obsolete with user-defined packaging, while the SL1021A090C is active and supplied in trays. Electrical and mechanical specifications are identical.

Q: Are there any compliance differences between SL1024A090C and SL1021A090C?

A: No. Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Both carry the same ECCN (EAR99) and HTSUS classifications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (user-defined versus tray) does not affect electrical characteristics or performance. Selection should be based on assembly process requirements and handling procedures.

Q: What parameters must match for a valid substitution?

A: Valid substitution requires matching voltage rating (90V), impulse discharge current (10kA), pole count (3), fail-short characteristic (No), package type (cylinder no-lead, 3 terminal), and compliance certifications (ROHS3, MSL 1).
