Substitute Part Grouping Explanation

The substitute part 170M6516 is identified as a functional alternative based on the following critical parameters:

• Voltage Rating Compatibility: Both parts operate at 700V AC, ensuring electrical system compatibility
• Current Rating Proximity: The substitute is rated at 1.25kA, representing a 4.2% increase over the original 1.2kA specification, within acceptable tolerance for fuse substitution in industrial applications
• Mounting Configuration: Both require holder-mounted installation, maintaining mechanical compatibility with existing assemblies
• Manufacturer Consistency: Both are manufactured by Eaton - Bussmann Electrical Division, ensuring design and quality standards alignment
• Regulatory Compliance: Both carry REACH Unaffected status and EAR99 ECCN classification

Parameter Comparison

Engineering Selection Recommendations

The 170M6516 is an active, in-stock alternative to the obsolete SPP-7K1200. Selection of this substitute is based on:

• Product Status: The 170M6516 maintains active manufacturing and distribution status, ensuring long-term availability and supply chain reliability
• Regulatory Compliance: Both parts share identical ECCN classification (EAR99) and HTSUS codes (8536.10.0040), confirming regulatory equivalence
• Electrical Compatibility: Matching 700V AC voltage rating and closely matched current rating (1.25kA vs. 1.2kA) ensure functional compatibility in the target application
• Mechanical Compatibility: Both require holder-mounted installation, maintaining assembly compatibility with existing infrastructure
• Third-Party Certifications: The 170M6516 carries CSA and UR approvals, providing additional assurance of safety and performance standards

Frequently Asked Questions (FAQ)

Q: Can the 170M6516 directly replace the SPP-7K1200 in existing installations?

A: Yes, provided the existing holder assembly is compatible with the rectangular blade package format of the 170M6516. Both parts require holder-mounted installation and operate at identical voltage ratings (700V AC).

Q: What is the significance of the current rating difference (1.2kA vs. 1.25kA)?

A: The 170M6516 is rated 4.2% higher in current capacity. This represents a minor increase and is acceptable for substitution in applications where the original 1.2kA specification was not a critical design constraint. System designers should confirm that the higher current rating does not conflict with circuit protection requirements.

Q: Why is the SPP-7K1200 classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this component. The 170M6516 is an active alternative that fulfills the same electrical and mechanical function.

Q: Are there any package or dimensional differences between these parts?

A: Yes. The SPP-7K1200 is a fuse link, while the 170M6516 is a square fuse with rectangular blade configuration. The 170M6516 dimensions are 2.008" L x 2.992" W x 3.622" H (51.00mm x 76.00mm x 92.00mm). Compatibility depends on the holder assembly design.

Q: What certifications apply to the 170M6516?

A: The 170M6516 carries CSA and UR approvals, indicating compliance with North American safety standards for electrical components.
