SL1024B600R Equivalent & Substitute Parts

Part Overview

The SL1024B600R is a Gas Discharge Tube (GDT) rated for 600V DC spark-over voltage with 20kA impulse discharge current capacity in a 3-pole through-hole configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Gas Discharge Tubes serve as surge protection devices in electrical circuits. The obsolete status of the SL1024B600R necessitates locating substitute components that maintain identical electrical performance and mechanical compatibility to ensure system reliability and continuity of supply.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SL1024B600R are identified based on strict equivalence of the following electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 600 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
• RoHS3 Compliance

The Bourns Inc. 2026-60-C2LF meets all substitution criteria. This part maintains identical electrical ratings and mechanical form factor, ensuring direct functional replacement in applications previously specified for the SL1024B600R.

Parameter Comparison

Engineering Selection Recommendations

The 2026-60-C2LF from Bourns Inc. is the qualified substitute for the obsolete SL1024B600R. Selection is based on:

• Identical electrical performance: 600V DC spark-over and 20kA impulse discharge current
• Mechanical compatibility: Through-hole mounting with axial cylinder form factor and 3-lead radial bend configuration
• Regulatory compliance: Both components meet ROHS3 requirements
• Product availability: The 2026-60-C2LF maintains active product status with established supply chain availability

The tolerance specification of ±20% on the 2026-60-C2LF does not affect substitution validity, as tolerance ranges define acceptable manufacturing variation within the same electrical class and do not alter functional equivalence for surge protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 2026-60-C2LF directly replace the SL1024B600R in existing designs?

A: Yes. Both components share identical voltage ratings (600V DC spark-over), discharge current capacity (20kA), pole configuration (3-pole), and mechanical form factor (through-hole, axial cylinder with radial bend leads). Direct substitution is valid without circuit modification.

Q: What is the significance of the ±20% tolerance on the 2026-60-C2LF?

A: Tolerance specifications define the acceptable range of manufacturing variation around the nominal spark-over voltage. The ±20% tolerance on the 2026-60-C2LF indicates that individual units may spark over between 480V and 720V, while maintaining the 600V nominal rating. This is standard for gas discharge tubes and does not prevent substitution.

Q: Are there any compliance differences between these parts?

A: Both components are ROHS3 compliant. The 2026-60-C2LF carries additional REACH Unaffected designation. Both share identical ECCN (EAR99) and HTSUS (8536.30.8000) classifications.

Q: Why is the SL1024B600R obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life decisions unrelated to technical performance. The 2026-60-C2LF provides equivalent functionality with active manufacturer support and supply availability.

Q: Does packaging format affect substitution?

A: The SL1024B600R is supplied in standard packaging, while the 2026-60-C2LF is supplied in trays. Packaging format does not affect electrical or mechanical compatibility. Tray packaging is standard for active production components and may offer improved handling and storage benefits.
