Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7F1200 is based on the following critical parameters:

• Voltage Rating: The substitute must maintain 700V AC rating to ensure safe operation in the original circuit
• Current Rating: The substitute current rating of 1.25kA is within acceptable tolerance for the 1.2kA requirement
• Mounting Configuration: The original part requires a holder; the substitute uses bolt mount, requiring mechanical adaptation
• Manufacturer Consistency: Both parts are from Eaton - Bussmann Electrical Division, ensuring design compatibility
• Regulatory Compliance: Both parts share identical ECCN and HTSUS classifications and maintain compliance standards

The substitute part 170M6716 meets the electrical requirements while offering active product status and enhanced specifications.

Engineering Selection Recommendations

The 170M6716 serves as the primary substitute for the obsolete SPP-7F1200 based on the following factors:

• Active Product Status: The 170M6716 is actively manufactured and stocked, ensuring long-term availability and supply chain reliability
• Electrical Compatibility: Both parts operate at 700V AC with current ratings within 4.2% tolerance (1.2kA vs. 1.25kA)
• Regulatory Alignment: Identical ECCN and HTSUS codes confirm equivalent classification for export and trade purposes
• Certification Coverage: The substitute carries CE, CSA, and UR approvals, meeting industrial and electrical standards
• Enhanced Specifications: The 170M6716 provides documented breaking capacity (200kA) and RoHS compliance, offering improved traceability and environmental compliance

Installation Consideration: The mounting configuration differs between parts. The original SPP-7F1200 requires a dedicated holder, while the 170M6716 uses bolt mount. Mechanical integration must be evaluated for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 170M6716 directly replace the SPP-7F1200 without modification?

A: Electrical substitution is valid based on voltage and current ratings. However, the mounting type differs (holder vs. bolt mount), requiring mechanical adaptation to the installation fixture.

Q: What is the current rating tolerance between these parts?

A: The SPP-7F1200 is rated at 1.2kA, while the 170M6716 is rated at 1.25kA. This represents a 4.2% increase, which is within acceptable tolerance for fuse substitution in industrial applications.

Q: Are both parts compliant with the same regulatory standards?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M6716 additionally carries CE, CSA, and UR certifications and is RoHS compliant.

Q: Why is the SPP-7F1200 listed as obsolete?

A: The SPP-7F1200 has been discontinued by the manufacturer. The 170M6716 is the active equivalent offering superior availability and compliance documentation.

Q: What is the breaking capacity difference?

A: The SPP-7F1200 breaking capacity is not specified in available documentation. The 170M6716 provides a documented breaking capacity of 200kA at rated voltage, offering enhanced fault protection specification.

Q: Are there packaging differences between these parts?

A: The SPP-7F1200 is supplied in standard packaging, while the 170M6716 is available in bulk packaging, suitable for high-volume industrial procurement.
