Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7M1100 is based on the following critical electrical and mechanical parameters:

• Current Rating: 1.1kA (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)

The substitute part 170M6565 meets these core substitution criteria. Both components are rated for identical current and voltage specifications, require holder-based mounting, and are manufactured by the same supplier. The primary difference lies in the physical form factor: the SPP-7M1100 is a fuse link, while the 170M6565 is a rectangular blade-type fuse. This form factor change necessitates verification of holder compatibility before installation.

Parameter Comparison

Engineering Selection Recommendations

The 170M6565 is the identified substitute for the obsolete SPP-7M1100 based on matching electrical specifications (1.1kA, 700V AC) and holder-based mounting architecture. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity.

Key considerations for selection:

• The 170M6565 is RoHS Compliant, whereas RoHS status for the SPP-7M1100 is not specified
• The 170M6565 holds CSA and UR approvals, providing third-party certification for industrial applications
• Physical dimensions differ between the link-type SPP-7M1100 and the rectangular blade-type 170M6565 (51.00mm x 76.00mm x 92.00mm), requiring holder compatibility verification
• The 170M6565 provides specified breaking capacity (200kA) and melting I²t (190000), enabling precise circuit protection analysis

Selection of the 170M6565 is appropriate for applications where holder compatibility can be confirmed and where the rectangular blade form factor is acceptable within the existing installation.

Frequently Asked Questions (FAQ)

Q: Can the 170M6565 directly replace the SPP-7M1100 without modification?

A: Both components require holder-based mounting and share identical electrical ratings (1.1kA, 700V AC). However, the SPP-7M1100 is a fuse link type while the 170M6565 is a rectangular blade type. Direct replacement requires confirmation that the existing holder accommodates the 170M6565 form factor (51.00mm x 76.00mm x 92.00mm).

Q: Why is the SPP-7M1100 listed as obsolete?

A: The SPP-7M1100 carries obsolete product status, indicating it is no longer in active production. The 170M6565 substitute maintains active status, ensuring continued availability for new installations and replacements.

Q: What are the key electrical parameters that define substitution eligibility?

A: Current rating (1.1kA) and voltage rating (700V AC) are the primary electrical parameters determining substitution. Both the SPP-7M1100 and 170M6565 meet these specifications exactly.

Q: Does the 170M6565 meet compliance requirements?

A: The 170M6565 is RoHS Compliant and holds CSA and UR approvals. The SPP-7M1100 carries REACH Unaffected status. Compliance requirements should be evaluated against specific application standards.

Q: What is the significance of the breaking capacity specification?

A: The 170M6565 specifies a breaking capacity of 200kA at rated voltage, defining the maximum fault current the fuse can safely interrupt. This parameter is not specified for the SPP-7M1100 and should be verified against circuit protection requirements.
