Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7K1100 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 1.1kA (must match exactly)
• Voltage Rating: 700V AC (must match exactly)
• Mounting Type: Requires Holder (mechanical compatibility requirement)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design consistency)

The substitute part 170M6515 meets all substitution criteria. Both components share identical current and voltage ratings, require holder mounting, and are manufactured by the same supplier. The transition from fuse link to square/rectangular form factor is acceptable within the same holder system, provided mechanical dimensions are compatible with the existing installation.

Parameter Comparison

Engineering Selection Recommendations

The 170M6515 is the qualified substitute for the obsolete SPP-7K1100. Selection is based on the following factors:

• Electrical equivalence: Both components are rated 1.1kA at 700V AC, ensuring identical circuit protection performance.
• Manufacturer consistency: Both are manufactured by Eaton - Bussmann Electrical Division, maintaining design and quality standards.
• Product status: The 170M6515 is active and in stock (989 pcs available), providing immediate availability for replacement applications.
• Compliance alignment: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, ensuring regulatory consistency.
• Mechanical compatibility: Both require holder mounting, maintaining installation compatibility with existing systems.

The form factor change from fuse link to rectangular blade configuration requires verification that the holder system accommodates the 170M6515 dimensions (51.00mm L x 76.00mm W x 92.00mm H).

Frequently Asked Questions (FAQ)

Q: Can the 170M6515 directly replace the SPP-7K1100 without modification?

A: The 170M6515 meets all electrical specifications (1.1kA, 700V AC) and mounting requirements (requires holder). However, the form factor differs (rectangular blade vs. fuse link). Direct replacement is possible only if the existing holder system is designed to accept the 170M6515 dimensions.

Q: What are the critical parameters for substitution?

A: Current rating (1.1kA), voltage rating (700V AC), and mounting type (requires holder) are the determining factors. Both the SPP-7K1100 and 170M6515 match these parameters exactly.

Q: Why is the SPP-7K1100 obsolete?

A: Product status is provided as obsolete in the manufacturer's database. The 170M6515 is the active equivalent and recommended for new designs and replacements.

Q: Are there compliance or regulatory differences between these parts?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. No regulatory barriers exist for substitution.

Q: What is the breaking capacity of the SPP-7K1100?

A: Breaking capacity is not specified for the SPP-7K1100. The 170M6515 provides 200kA breaking capacity at rated voltage, which may exceed the original design specification.

Q: How do the physical dimensions affect substitution?

A: The 170M6515 measures 51.00mm L x 76.00mm W x 92.00mm H. Compatibility depends on whether the existing holder system accommodates these dimensions. Physical verification is required before installation.
