SL1011B090C Equivalent & Substitute Parts

Part Overview

The SL1011B090C is a Gas Discharge Tube (GDT) rated for 90V DC spark-over voltage with 10kA impulse discharge current capacity in a 2-pole configuration. This component is classified as Obsolete, which necessitates identification of active equivalent alternatives for continued system design and procurement. The SL1011B series has been superseded by the SL1411A series while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1011B090C is based on strict equivalence of the following electrical and mechanical parameters:

• Voltage - DC Spark Over (Nominal): 90 V
• Impulse Discharge Current (8/20µs): 10000A (10kA)
• Number of Poles: 2
• Fail Short characteristic: No
• Package / Case: Cylinder No Lead
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The SL1411A090C meets all these criteria and represents the active product line successor to the obsolete SL1011B series.

Parameter Comparison

Engineering Selection Recommendations

The SL1411A090C is the direct equivalent for the obsolete SL1011B090C. Both components share identical electrical ratings, mechanical form factor, and regulatory compliance status. The SL1411A090C is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance and carry identical export classification (EAR99) and tariff codes (HTSUS 8536.30.8000). Selection of the SL1411A090C eliminates obsolescence risk while preserving all functional and physical compatibility requirements.

Frequently Asked Questions (FAQ)

Q: Can the SL1411A090C be used as a direct replacement for the SL1011B090C?

A: Yes. Both components are electrically and mechanically identical across all specified parameters: 90V DC spark-over voltage, 10kA impulse discharge current, 2-pole configuration, and Cylinder No Lead package. The SL1411A090C represents the active product line continuation.

Q: What is the difference between the SL1011B and SL1411A series?

A: The SL1011B series is obsolete, while the SL1411A series is active. No electrical or mechanical differences exist between these specific part numbers. The series designation change reflects product line consolidation by the manufacturer.

Q: Are there any packaging differences between these parts?

A: No. Both the SL1011B090C and SL1411A090C use identical Cylinder No Lead packaging. The standard packaging for the SL1411A090C is Bulk, which is suitable for production environments.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS (8536.30.8000) classifications.

Q: Is there a difference in availability or lead time?

A: The SL1411A090C is in active production status, ensuring standard lead times and ongoing availability. The SL1011B090C is obsolete and subject to limited remaining inventory.
