Key Parameters

Substitute Part Grouping Explanation

The 170M3614 serves as a functional substitute based on the following critical parameters:

• Voltage Rating: Both parts operate at 700V AC, ensuring electrical compatibility
• Manufacturer: Both manufactured by Eaton - Bussmann Electrical Division, maintaining design consistency and quality standards
• Current Rating: The 170M3614 is rated at 160A, providing equivalent or superior current handling capacity relative to the 150A SPP-4B150
• Regulatory Compliance: Both parts carry ECCN EAR99 classification and maintain equivalent export control status
• Approval Agencies: The 170M3614 holds CE, CSA, and UR certifications, meeting industrial and electrical application standards

The primary distinction lies in mounting configuration: the SPP-4B150 requires a separate holder, while the 170M3614 features bolt mount construction. This difference necessitates mechanical integration assessment during substitution.

Parameter Comparison

Engineering Selection Recommendations

The 170M3614 is an active, production component manufactured by the same supplier as the obsolete SPP-4B150. Selection of this substitute is supported by:

• Voltage and current rating compatibility within the specified electrical parameters
• Active product status ensuring long-term availability and supply chain stability
• RoHS compliance status providing environmental and regulatory alignment
• Equivalent ECCN classification maintaining export control consistency
• Approval certifications (CE, CSA, UR) meeting industrial electrical standards

Mechanical integration requires evaluation of the bolt mount configuration against the original holder-based mounting scheme to ensure proper installation within existing electrical enclosures and systems.

Frequently Asked Questions (FAQ)

Q: Can the 170M3614 directly replace the SPP-4B150 in existing installations?

A: Electrical compatibility is established through matching voltage ratings (700V) and equivalent current capacity (160A vs. 150A). However, the mounting configuration differs: the SPP-4B150 requires a separate holder, while the 170M3614 uses bolt mount construction. Physical integration assessment is necessary to confirm mechanical compatibility with existing mounting infrastructure.

Q: What are the key parameters determining substitution eligibility?

A: Voltage rating, current rating, manufacturer consistency, and regulatory compliance status are the primary criteria. Both parts operate at 700V, are manufactured by Eaton - Bussmann Electrical Division, and carry equivalent ECCN classifications. The 160A rating of the 170M3614 meets or exceeds the 150A requirement of the SPP-4B150.

Q: Why is the SPP-4B150 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 170M3614 represents the active alternative within the Eaton - Bussmann product portfolio, ensuring continued availability and supply chain support.

Q: Are there compliance differences between these parts?

A: Both parts carry ECCN EAR99 classification. The 170M3614 additionally specifies RoHS compliance, indicating alignment with current environmental regulations. This represents an enhancement rather than a limitation for substitution purposes.

Q: What is the significance of the breaking capacity specification?

A: The 170M3614 specifies 200kA breaking capacity at rated voltage, indicating the maximum fault current the fuse can safely interrupt. This parameter is not provided for the SPP-4B150 in the available data.
