Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-4M80 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 80A (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 consistency)

The substitute part 170M3561 meets all substitution criteria. Although it differs in fuse type (Square vs. Stud Link) and package configuration (Rectangular Blade vs. Fuse Link), it maintains identical electrical ratings and is compatible with holder-based mounting systems. The 170M3561 is an active product, providing continuity of supply for the obsolete SPP-4M80.

Parameter Comparison

Engineering Selection Recommendations

The 170M3561 is the designated substitute for the obsolete SPP-4M80. Selection is based on:

• Identical electrical ratings (80A, 700VAC)
• Same manufacturer (Eaton - Bussmann Electrical Division)
• Active product status ensuring availability and supply continuity
• Holder-based mounting compatibility
• CSA and UR approvals provide regulatory compliance for industrial and electrical applications
• RoHS compliance status aligns with modern environmental standards

The 170M3561 is suitable for direct replacement in applications where the SPP-4M80 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the 170M3561 directly replace the SPP-4M80?

A: Yes. Both components share identical electrical ratings (80A, 700VAC) and require holder-based mounting. The 170M3561 is an active product from the same manufacturer, providing functional equivalence for the obsolete SPP-4M80.

Q: What is the difference between the SPP-4M80 and 170M3561?

A: The primary differences are fuse type (Stud Link vs. Square) and package configuration (Fuse Link vs. Rectangular Blade). These are mechanical variations that do not affect electrical performance when used with appropriate holders. The 170M3561 offers additional specifications including breaking capacity (200kA) and regulatory approvals (CSA, UR).

Q: Are there compatibility concerns with different holder types?

A: Both components require holder-based mounting systems. Verify that the holder used with the SPP-4M80 is compatible with the 170M3561's rectangular blade configuration before installation.

Q: What is the inventory status of these parts?

A: The SPP-4M80 has 1042 pieces in stock (obsolete status). The 170M3561 has 1093 pieces in stock and is actively produced.

Q: Do these fuses have the same regulatory approvals?

A: The 170M3561 carries CSA and UR approvals. Regulatory approval information for the SPP-4M80 is not specified in available documentation. Both components share the same ECCN (EAR99) and HTSUS classification.
