SSC_N230/02 Equivalent & Substitute Parts

Part Overview

The SSC_N230/02 is a gas discharge tube (GDT) rated for 230 V DC spark over voltage with an impulse discharge current capacity of 20000A (20kA). This component is designed for 2-pole chassis and stud mount applications, providing overvoltage protection in electrical systems. The SSC_N230/02 is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this protection topology is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSC_N230/02 is determined by the following critical parameters:

Primary Matching Criteria:

• Impulse discharge current capacity (8/20µs waveform)
• Voltage rating (DC spark over nominal value)
• Number of poles
• Fail short characteristic
• Regulatory compliance (REACH, ECCN)

Substitution Logic:

The SSC_N230/02 has two manufacturer-recommended substitutes from Huber+Suhner, Inc., each addressing different application requirements:

Substitute 1: 3402.17.3002 maintains the same impulse discharge current (20kA) and pole count (2 poles) as the original part. The primary difference is the mounting configuration, which changes from chassis/stud mount to free hanging (in-line). This substitute is suitable for applications where the mechanical mounting interface can accommodate in-line configuration while preserving the electrical protection characteristics.

Substitute 2: 9071.99.0547 (73_Z-0-0-547) maintains the same voltage rating (230 V) and fail short characteristic as the original part. This substitute increases the impulse discharge current capacity to 30kA and reduces the pole count to 1 pole. The mounting type changes to surface mount with cartridge packaging. This substitute is applicable in designs where higher surge current capacity is acceptable and single-pole protection is sufficient.

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalence:

Part 3402.17.3002 provides the closest electrical match to the SSC_N230/02, maintaining identical impulse discharge current (20kA) and pole count (2 poles). Both parts are manufactured by Huber+Suhner, Inc., and share identical fail short characteristics and regulatory compliance status (REACH Unaffected, EAR99). Selection of this substitute is appropriate when the application can accommodate a change from chassis/stud mount to free hanging (in-line) mechanical configuration. This part is currently in active production status with 763 units in stock.

For Enhanced Surge Protection:

Part 9071.99.0547 (73_Z-0-0-547) offers increased impulse discharge current capacity (30kA versus 20kA) while maintaining the 230 V voltage rating. This substitute is suitable for applications requiring higher surge current handling capability. The reduction from 2 poles to 1 pole and the change to surface mount configuration require circuit topology evaluation. This part is currently in active production status with 991 units in stock and includes RoHS3 compliance certification.

Regulatory and Compliance Considerations:

All three parts (main and substitutes) maintain REACH Unaffected status and EAR99 ECCN classification, ensuring consistent regulatory treatment across substitution options.

Frequently Asked Questions (FAQ)

Q: Can 3402.17.3002 be used as a direct replacement for SSC_N230/02?

A: Part 3402.17.3002 is electrically equivalent in terms of voltage rating, impulse discharge current (20kA), pole count (2), and fail short characteristic. The primary difference is the mounting type: 3402.17.3002 uses free hanging (in-line) configuration while SSC_N230/02 uses chassis/stud mount. Substitution is valid when the mechanical mounting interface can be adapted to accommodate in-line configuration.

Q: What are the key differences between the two substitute parts?

A: Part 3402.17.3002 maintains the same impulse discharge current (20kA) and pole count (2) as the original SSC_N230/02, with a change to in-line mounting. Part 9071.99.0547 increases impulse discharge current to 30kA, reduces pole count to 1, and uses surface mount configuration. The voltage rating remains 230 V for both substitutes.

Q: Is 9071.99.0547 suitable for applications requiring 2-pole protection?

A: Part 9071.99.0547 is a 1-pole device, whereas SSC_N230/02 is a 2-pole device. Substitution requires evaluation of the circuit topology to determine whether single-pole protection is sufficient for the intended application.

Q: What is the significance of the increased 30kA rating in 9071.99.0547?

A: The 30kA impulse discharge current rating in 9071.99.0547 provides higher surge current handling capacity compared to the 20kA rating of SSC_N230/02. This increased capacity is applicable in systems experiencing higher transient surge currents while maintaining the same 230 V spark over voltage.

Q: Are all three parts compliant with the same regulatory standards?

A: All three parts (SSC_N230/02, 3402.17.3002, and 9071.99.0547) maintain REACH Unaffected status and EAR99 ECCN classification. Part 9071.99.0547 additionally carries RoHS3 compliance certification.

Q: What packaging differences exist between the substitutes?

A: SSC_N230/02 uses standard packaging (not specified in detail). Part 3402.17.3002 is supplied in bulk packaging. Part 9071.99.0547 uses cartridge package type and is supplied in bulk packaging.

Q: Which substitute should be selected for new designs?

A: Selection depends on specific application requirements. For applications requiring 2-pole protection with 20kA capacity and in-line mounting capability, select 3402.17.3002. For applications where 1-pole protection with 30kA capacity and surface mount configuration are acceptable, select 9071.99.0547. Both parts are in active production status.
