SPP-5F500 Equivalent & Substitute Parts

Part Overview

The SPP-5F500 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 500A at 700V with blade mounting. This component is classified as obsolete and requires a holder for operation. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for system maintenance, repair, and continued operational support where original inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M4714 is identified as functionally equivalent based on the following critical parameters:

• Current Rating: Both parts are rated for 500A
• Voltage Rating: Both parts are rated for 700V AC
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division
• Compliance: Both share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications
• Regulatory Status: Both are REACH Unaffected

The 170M4714 differs in mounting configuration (bolt mount versus blade mount holder requirement) and fuse type classification (square versus link), but maintains electrical equivalence in current and voltage ratings, making it suitable for applications requiring 500A / 700V protection.

Parameter Comparison

Engineering Selection Recommendations

The 170M4714 is an active product substitute for the obsolete SPP-5F500, providing equivalent electrical protection at 500A / 700V. Selection of the 170M4714 is supported by:

• Product Availability: Active status ensures continued supply and support
• Regulatory Compliance: Identical ECCN and HTSUS classifications confirm regulatory equivalence
• Electrical Equivalence: Matching current and voltage ratings ensure functional compatibility in 500A / 700V circuits
• Manufacturer Continuity: Both parts originate from Eaton - Bussmann Electrical Division, ensuring design consistency and quality standards

Substitution requires verification that the bolt mount configuration of the 170M4714 is compatible with the installation environment, as this differs from the holder-based mounting of the SPP-5F500.

Frequently Asked Questions (FAQ)

Q: Can the 170M4714 directly replace the SPP-5F500?

A: Both parts provide 500A / 700V protection and are manufactured by the same supplier. However, the mounting configuration differs: the SPP-5F500 requires a holder, while the 170M4714 uses bolt mount. Installation compatibility depends on the existing mounting infrastructure.

Q: What are the key electrical parameters for substitution?

A: Current rating (500A) and voltage rating (700V) are the primary parameters determining substitution eligibility. Both parts meet these specifications.

Q: Why is the SPP-5F500 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M4714 is an active alternative that maintains electrical equivalence.

Q: Are there compliance differences between these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, confirming regulatory equivalence for export and trade purposes.

Q: What is the difference between "Fuse Link" and "Square" fuse types?

A: These designations refer to physical form factor and mounting method. The SPP-5F500 is a link-type fuse requiring a holder; the 170M4714 is a square-type fuse with bolt mount. Both provide equivalent electrical protection at the specified ratings.
