Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A090RF is based on strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 90V
• 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 SL1021A090RF meets all substitution criteria as an active product offering identical electrical performance and mechanical compatibility with the obsolete SL1024A090RF.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A090RF is the direct substitute for the obsolete SL1024A090RF. Both components are manufactured by Littelfuse Inc. and maintain identical electrical ratings and mechanical form factors. The SL1021A090RF carries active product status, ensuring ongoing availability and supply chain continuity. Both parts meet ROHS3 compliance requirements and share equivalent moisture sensitivity classifications. The primary distinction is packaging format: the SL1024A090RF was supplied in standard packaging, while the SL1021A090RF is available in tray packaging. This packaging difference does not affect electrical or mechanical compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A090RF be used as a direct replacement for the SL1024A090RF?

A: Yes. The SL1021A090RF is electrically and mechanically equivalent to the SL1024A090RF across all critical parameters: 90V DC spark-over voltage, 10kA impulse discharge current, 3-pole configuration, through-hole mounting, and identical package geometry.

Q: What is the difference between the SL1024A090RF and SL1021A090RF?
