SPP-7M1000 Equivalent & Substitute Parts

Part Overview

The SPP-7M1000 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 1kA at 700V. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying equivalent substitute parts is essential for system maintenance, repair, and continued operation in electrical and industrial applications where this fuse type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7M1000 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 1kA (must match exactly)
• Voltage Rating: 700V AC (must match exactly)
• Mounting Type: Requires Holder (mechanical compatibility requirement)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Regulatory Compliance: REACH Unaffected and EAR99 classification (must be maintained)

The substitute part 170M6564 meets all these criteria. While it differs in fuse type classification (Square vs. Fuse Link designation) and package dimensions, it maintains electrical equivalence through identical current and voltage ratings, identical mounting requirements, and equivalent regulatory status.

Parameter Comparison

Engineering Selection Recommendations

The 170M6564 is the direct substitute for the obsolete SPP-7M1000 based on electrical equivalence. Both components share identical current (1kA) and voltage (700V) ratings, identical mounting requirements (holder-based installation), and identical export classification (EAR99). The 170M6564 is currently in active production status with 5300 units in stock, providing immediate availability for replacement applications.

The 170M6564 carries CSA and UR approvals and is RoHS compliant, meeting modern regulatory requirements. The specified breaking capacity of 200kA and melting I²t of 140000 provide documented performance characteristics for circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 170M6564 directly replace the SPP-7M1000 in existing installations?

A: Yes. Both components have identical current ratings (1kA) and voltage ratings (700V AC), identical mounting requirements (holder-based), and are manufactured by the same company. The electrical performance is equivalent for the specified circuit protection application.

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

A: These designations refer to physical form factor and internal construction. Both the SPP-7M1000 (Fuse Link) and 170M6564 (Square) are holder-mounted fuses with identical electrical ratings. The form factor difference does not affect electrical substitution when the holder is compatible with both designs.

Q: Why is the SPP-7M1000 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M6564 is the active production equivalent, ensuring continued availability for maintenance and replacement needs.

Q: Are there any compliance differences between the two parts?

A: Both parts share the same ECCN classification (EAR99) and HTSUS code (8536.10.0040). The 170M6564 includes CSA and UR approvals and is RoHS compliant, meeting current regulatory standards.

Q: What inventory status should I expect?

A: The SPP-7M1000 has 757 units in stock as legacy inventory. The 170M6564 has 5300 units in active stock, providing superior availability for new orders and replacements.
