GT-RLSA200SS Gas Discharge Tube Equivalent & Substitute Parts

Part Overview

The GT-RLSA200SS is a 2-pole gas discharge tube (GDT) manufactured by Lumex Opto/Components Inc., designed for overvoltage protection applications. This through-hole component features a 200V DC spark-over voltage rating and 1000A (1kA) impulse discharge current capacity with ±15% tolerance. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the critical parameters that define functional interchangeability in gas discharge tube applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GT-RLSA200SS are identified based on strict equivalence of the following parameters:

Critical Electrical Parameters:

• Voltage - DC Spark Over (Nominal): 200 V
• Impulse Discharge Current (8/20µs): 1000A (1kA)
• Number of Poles: 2
• Fail Short characteristic: No

Critical Mechanical Parameters:

• Mounting Type: Through Hole
• Functional package compatibility

Regulatory Compliance:

• RoHS3 Compliant status
• REACH Unaffected status

The substitute part B88069X8801B502 meets all critical electrical and mechanical requirements. Tolerance variation (±20% vs ±15%) represents a secondary parameter difference that does not prevent functional substitution when circuit design margins accommodate the broader tolerance range.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (GT-RLSA200SS): The GT-RLSA200SS maintains Active product status with 609 units in stock. This part is suitable for applications requiring radial package geometry and ±15% tolerance specification. ROHS3 compliance and REACH unaffected status satisfy regulatory requirements for most industrial and consumer applications.

Substitute Selection (B88069X8801B502): The B88069X8801B502 provides functional equivalence with 2376 units available in stock. This EPCOS - TDK Electronics component matches all critical electrical parameters and maintains identical regulatory compliance. The axial cylinder package geometry differs from the radial configuration, requiring PCB layout verification for mechanical fit. The ±20% tolerance is broader than the primary part; circuit design must confirm that this tolerance range remains within acceptable operating margins.

Both parts are Active products with ROHS3 compliance and REACH unaffected status, supporting long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can B88069X8801B502 replace GT-RLSA200SS in existing designs?

A: Electrical and functional replacement is supported. The substitute part matches the 200V spark-over voltage, 1kA impulse discharge current, 2-pole configuration, and through-hole mounting. Physical package geometry differs (axial cylinder vs radial), requiring verification that PCB footprint and lead spacing accommodate the substitute component.

Q: What is the impact of ±20% tolerance versus ±15% tolerance?

A: The substitute part B88069X8801B502 operates within a broader tolerance band. Circuit designs must confirm that protection thresholds and performance margins remain acceptable across the full ±20% tolerance range of the substitute component.

Q: Are both parts suitable for new designs?

A: Both GT-RLSA200SS and B88069X8801B502 maintain Active product status. Either part is appropriate for new designs. Selection should consider package geometry requirements, tolerance specifications, and inventory availability.

Q: Do both parts meet regulatory requirements?

A: Both components are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for applications subject to these standards.

Q: What is the difference between radial and axial cylinder packages?

A: Radial packages (GT-RLSA200SS) feature leads extending from the same end of the component body. Axial cylinder packages (B88069X8801B502) feature leads extending from opposite ends. PCB footprint, lead spacing, and mounting hole positioning differ between these geometries.
