SPP-7F1000 Equivalent & Substitute Parts

Part Overview

The SPP-7F1000 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 1kA at 700V. This component is part of the Semitron™ SPP series and requires a dedicated holder for installation. The part is currently obsolete, making identification of suitable substitute components essential for system maintenance and replacement applications. Obsolete status necessitates sourcing of functionally equivalent alternatives that maintain electrical and mechanical compatibility with existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7F1000 is based on electrical parameter alignment and regulatory compliance. The primary substitute, 170M6714, shares the critical electrical specifications: 1kA current rating and 700VAC voltage rating. Both components are manufactured by Eaton - Bussmann Electrical Division, ensuring consistency in design standards and quality control.

The key parameters determining substitution eligibility are:

• Current Rating: 1kA (identical)
• Voltage Rating: 700V AC (identical)
• Manufacturer: Eaton - Bussmann Electrical Division (same source)
• Regulatory Compliance: Both carry ECCN EAR99 and HTSUS 8536.10.0040 classifications

The 170M6714 differs in mounting configuration (bolt mount versus holder-based installation) and fuse form factor (square versus blade), which may require mechanical adaptation in the installation environment.

Parameter Comparison

Engineering Selection Recommendations

The 170M6714 is the designated substitute for the obsolete SPP-7F1000 based on electrical parameter equivalence. Both components maintain identical current and voltage ratings (1kA at 700V), ensuring electrical compatibility in circuit protection applications.

The 170M6714 carries active product status with current manufacturing support, whereas the SPP-7F1000 is obsolete. The substitute component holds multiple regulatory approvals (CE, CSA, UR) and RoHS compliance, providing enhanced regulatory alignment for modern installations.

Mechanical integration requires consideration: the SPP-7F1000 uses a blade-type fuse requiring a dedicated holder, while the 170M6714 employs bolt-mount configuration with square form factor. Installation environments must accommodate this mounting difference through appropriate hardware or adapter solutions.

Frequently Asked Questions (FAQ)

Q: Can the 170M6714 directly replace the SPP-7F1000 without modification?

A: Electrical compatibility is confirmed through identical current and voltage ratings. Mechanical installation requires assessment of the existing mounting infrastructure. The SPP-7F1000 blade-type holder configuration differs from the 170M6714 bolt-mount design, necessitating evaluation of available mounting space and fastening capability.

Q: What are the critical electrical parameters for substitution?

A: Current rating (1kA) and voltage rating (700V AC) are the primary electrical parameters determining substitution eligibility. Both the SPP-7F1000 and 170M6714 meet these specifications identically.

Q: Why is the 170M6714 recommended over other potential alternatives?

A: The 170M6714 is the specified substitute based on manufacturer designation and electrical parameter alignment. Both components originate from Eaton - Bussmann Electrical Division, ensuring consistency in design standards and quality assurance protocols.

Q: What is the significance of the 200kA breaking capacity on the 170M6714?

A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt at rated voltage. The 170M6714 specification of 200kA at rated voltage provides documented fault-handling capability for circuit protection applications.

Q: Are there regulatory compliance differences between these components?

A: The 170M6714 holds CE, CSA, and UR approvals with RoHS compliance status. The SPP-7F1000 specifications do not document these certifications. Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications for export and tariff purposes.

Q: What does the Melting I²t value represent?

A: Melting I²t (140000.0 for the 170M6714) quantifies the thermal energy required to melt the fuse element. This parameter characterizes fuse response time and thermal behavior under fault conditions.
