SL1024B230R Gas Discharge Tube - Equivalent & Substitute Parts

Part Overview

The SL1024B230R is a 3-pole gas discharge tube (GDT) rated for 230V DC spark-over voltage with an impulse discharge current capacity of 20kA (8/20µs). Manufactured by Littelfuse Inc., this component is designed for through-hole mounting applications requiring overvoltage protection in multi-pole configurations.

The SL1024B230R is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL1024B230R is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 230 V
• Impulse Discharge Current (8/20µs): 20000A (20kA)
• Number of Poles: 3
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)
• Fail Short Characteristic: No

The SL1021B230R meets all substitution criteria. While classified as active (versus obsolete), it maintains identical electrical ratings, mechanical configuration, and environmental compliance specifications.

Parameter Comparison

Engineering Selection Recommendations

The SL1021B230R is the direct equivalent substitute for the SL1024B230R. Both components are manufactured by Littelfuse Inc. and share identical electrical performance specifications, mechanical form factors, and environmental compliance certifications.

The primary distinction is product status: the SL1024B230R is obsolete, while the SL1021B230R is active. The SL1021B230R is available in tray packaging and maintains full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current production requirements.

Frequently Asked Questions (FAQ)

Q: Can the SL1021B230R be used as a direct replacement for the SL1024B230R?

A: Yes. Both components are electrically and mechanically equivalent. They share identical 230V DC spark-over voltage, 20kA impulse discharge current rating, 3-pole configuration, through-hole mounting, and axial cylinder package geometry.

Q: What is the difference between the SL1024B230R and SL1021B230R?

A: The primary difference is product lifecycle status. The SL1024B230R is obsolete, while the SL1021B230R is active. The SL1021B230R is supplied in tray packaging. All electrical, mechanical, and compliance specifications are identical.

Q: Are there packaging differences between these parts?

A: The SL1024B230R and SL1021B230R use the same axial cylinder, 3-lead radial bend package. The SL1021B230R is supplied in tray packaging format, which is standard for active production components.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the SL1024B230R and SL1021B230R are ROHS3 compliant. The SL1021B230R additionally carries REACH unaffected status, confirming compliance with current environmental regulations.

Q: Can I use these parts interchangeably in my circuit design?

A: Yes. The identical electrical ratings (230V spark-over, 20kA impulse current), mechanical configuration (3-pole through-hole), and fail-short characteristics ensure direct interchangeability in circuit applications.
