SL1024A090RG Equivalent & Substitute Parts

Part Overview

The SL1024A090RG is a Gas Discharge Tube (GDT) rated for 90V DC spark-over voltage with 10kA impulse discharge current capacity. This component is designed for 3-pole through-hole applications and features fail-short characteristics for overvoltage protection in electronic circuits.

The SL1024A090RG is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1024A090RG is determined by strict equivalence across the following critical parameters:

• Voltage - DC Spark Over (Nominal): 90 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 3
• Fail Short: Yes
• Mounting Type: Through Hole
• Package / Case: Axial Cylinder, 3 Lead (Radial Bend)

The SL1021A090RF meets all these criteria and is classified as an active product from the same manufacturer (Littelfuse Inc.), making it a direct functional equivalent for the obsolete SL1024A090RG.

Parameter Comparison

Engineering Selection Recommendations

The SL1021A090RF is the direct substitute for the obsolete SL1024A090RG. Both components are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters.

The SL1021A090RF carries active product status, ensuring ongoing availability and manufacturer support. Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) ratings, confirming compatibility with standard manufacturing and storage environments.

The SL1021A090RF is supplied in tray packaging, whereas the original part number does not specify packaging format. This difference does not affect functional performance or circuit-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SL1021A090RF be used as a direct replacement for the SL1024A090RG?

A: Yes. The SL1021A090RF is a direct functional equivalent. Both components share identical voltage ratings (90V DC spark-over), discharge current capacity (10kA), pole configuration (3-pole), fail-short behavior, mounting type (through-hole), and package form factor (Axial Cylinder, 3 Lead with Radial Bend).

Q: Why is the SL1024A090RG classified as obsolete?

A: The SL1024A090RG is no longer in active production. The SL1021A090RF from the same manufacturer serves as the current active equivalent and should be used for new designs and ongoing supply requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SL1024A090RG and SL1021A090RF maintain identical RoHS3 compliance and MSL 1 (Unlimited) ratings. Both carry ECCN EAR99 and HTSUS 8536.30.8000 classifications.

Q: Does the packaging difference (tray vs. unspecified) affect compatibility?

A: No. Packaging format does not affect electrical performance or circuit-level functionality. The tray packaging of the SL1021A090RF is a supply-chain consideration only and does not impact component operation or installation.

Q: What are the critical parameters for GDT substitution?

A: For Gas Discharge Tubes, the critical parameters are voltage rating (DC spark-over), impulse discharge current capacity, number of poles, fail-short behavior, mounting type, and physical package form factor. All of these must match between the original and substitute component.
