Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M6512 qualifies as an equivalent based on the following critical parameters:

• Current Rating: Both parts are rated for 800A
• Voltage Rating: Both parts are rated for 700V AC
• Mounting Type: Both require a holder for installation
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division
• Regulatory Compliance: Both share identical ECCN (EAR99) and HTSUS classifications

The primary difference is the package configuration: SPP-7K800 uses a fuse link package, while 170M6512 uses a rectangular blade package. Both configurations maintain the same electrical performance characteristics at the specified current and voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

The 170M6512 is an active product substitute for the obsolete SPP-7K800. Both components share identical electrical ratings (800A, 700V) and are manufactured by the same supplier. The 170M6512 carries active product status and maintains full compliance with regulatory requirements (ECCN EAR99, HTSUS 8536.10.0040).

The primary consideration for substitution is the physical package difference: the 170M6512 uses a rectangular blade configuration instead of the fuse link format. Compatibility depends on the holder design in the target application. Verify that the application's fuse holder accommodates the rectangular blade package dimensions (2.008" L x 2.992" W x 3.622" H).

Frequently Asked Questions (FAQ)

Q: Can 170M6512 directly replace SPP-7K800 in all applications?

A: Both parts have identical electrical ratings (800A, 700V) and require holder mounting. Substitution is electrically valid. Physical compatibility depends on whether the existing holder accepts the rectangular blade package format of the 170M6512.

Q: What is the key difference between these two fuse types?

A: The SPP-7K800 uses a fuse link package, while the 170M6512 uses a rectangular blade package. Both deliver the same electrical performance at 800A and 700V.

Q: Why is SPP-7K800 listed as obsolete?

A: SPP-7K800 is no longer in active production. The 170M6512 represents the current active equivalent from the same manufacturer.

Q: Are there any compliance differences between these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. Regulatory compliance is equivalent.

Q: What should I verify before substituting?

A: Confirm that your fuse holder is designed to accept the rectangular blade package configuration of the 170M6512. Electrical specifications are fully compatible.
