Parameter Comparison

Engineering Selection Recommendations

The 170M4564 is the direct substitute for SPP-5M500 based on matching electrical ratings (500A, 700V) and identical regulatory classifications. The substitute part is currently active in production with documented inventory availability, whereas the original part is obsolete. Both components are manufactured by the same supplier and share identical trade classification codes, ensuring regulatory and procurement consistency.

The 170M4564 provides additional documented specifications including breaking capacity (200kA) and melting I²t (25000), which are not specified for the original part but represent standard performance characteristics for this current and voltage class.

Frequently Asked Questions (FAQ)

Q: Can 170M4564 directly replace SPP-5M500 in existing installations?

A: Yes. Both parts share identical current rating (500A), voltage rating (700V), and mounting requirements (holder-based installation). The substitute is manufactured by the same supplier and carries the same regulatory classifications.

Q: What is the difference between the package types listed?

A: SPP-5M500 is designated as a "Fuse Link" while 170M4564 is specified as "Rectangular, Blade." Both require external holders for installation. The physical form factor difference does not affect electrical compatibility when used with appropriate holders.

Q: Why is SPP-5M500 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 170M4564 substitute is actively manufactured and stocked, making it the recommended choice for new installations and replacements.

Q: Are there compliance differences between the two parts?

A: No. Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, indicating equivalent regulatory treatment for export and trade purposes.

Q: What additional specifications does 170M4564 provide?

A: The substitute part includes documented breaking capacity of 200kA at rated voltage and melting I²t of 25000. These specifications define the fuse's performance under fault conditions and are standard for 500A, 700V fuses in this class.
