Key Parameters

Substitute Part Grouping Explanation

The Eaton Bussmann CBC-35 is identified as a manufacturer-recommended substitute for the 0813035.ZXST. Substitution eligibility is determined by the following critical parameters:

• Current Rating: Both parts rated at 35A
• Actuator Type: Both feature automatic reset functionality
• Number of Poles: Both are single-pole configurations
• Mounting Type: Both utilize chassis mount design
• Voltage Rating - DC: Main part rated 12V; substitute rated 14V (higher voltage rating provides compatibility with 12V applications)

The CBC-35 maintains functional equivalence across all core electrical and mechanical parameters while offering improved compliance status and active production availability.

Parameter Comparison

Engineering Selection Recommendations

The CBC-35 from Eaton - Bussmann Electrical Division is the designated equivalent for the obsolete 0813035.ZXST. Selection of the CBC-35 is supported by:

• Identical current and pole ratings ensuring direct functional replacement
• Higher DC voltage rating (14V vs. 12V) providing margin for 12V applications
• Active production status ensuring long-term availability and supply chain continuity
• RoHS compliance meeting modern regulatory requirements, whereas the original part is RoHS non-compliant
• Equivalent HTSUS classification (8536.20.0020) confirming tariff and trade alignment

For applications requiring the original 0813035.ZXST, existing inventory of 843 pieces remains available. For new designs or long-term system support, the CBC-35 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can the CBC-35 directly replace the 0813035.ZXST in existing applications?

A: Yes. Both parts share identical current ratings (35A), automatic reset functionality, single-pole configuration, and chassis mount design. The CBC-35's higher voltage rating (14V) is compatible with 12V DC systems.

Q: What is the significance of the voltage rating difference (12V vs. 14V)?

A: The CBC-35 is rated for 14V DC, which exceeds the 12V requirement of the original part. A higher voltage rating indicates the component can safely operate at the lower voltage without performance degradation.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance indicates the part meets current environmental and regulatory standards for hazardous substance restrictions. The CBC-35's RoHS compliance makes it suitable for applications subject to modern regulatory requirements, whereas the original part does not meet these standards.

Q: Are there packaging considerations when switching to the CBC-35?

A: The CBC-35 is supplied in bulk packaging. Verify that bulk packaging meets your procurement and inventory management requirements compared to the original part's packaging specification.

Q: What is the inventory status for each part?

A: The original 0813035.ZXST has 843 pieces in stock as new original inventory. The CBC-35 has 1,148 pieces available. Both parts are currently available for procurement.
