Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7K900 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 900A (exact match required)
• Voltage Rating: 700V AC (exact match required)
• Mounting Type: Requires Holder (mechanical compatibility)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)

The substitute part 170M6513 meets all substitution criteria. It maintains identical current and voltage ratings, operates within the same holder-based mounting architecture, and is manufactured by the same supplier. The transition from fuse link to rectangular blade configuration represents a form factor change while preserving electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The 170M6513 is the designated substitute for the obsolete SPP-7K900. Both components share identical electrical ratings (900A, 700V AC) and are manufactured by Eaton - Bussmann Electrical Division, ensuring design and performance compatibility within holder-based mounting systems.

The 170M6513 holds active product status with current manufacturing support, whereas the SPP-7K900 is obsolete. The substitute part carries CSA and UR approvals and is RoHS compliant, providing enhanced regulatory alignment for new installations and system upgrades.

The form factor transition from fuse link to rectangular blade configuration requires mechanical verification that the holder assembly accommodates the substitute part's dimensions (2.008" L x 2.992" W x 3.622" H).

Frequently Asked Questions (FAQ)

Q: Can the 170M6513 directly replace the SPP-7K900 in existing systems?

A: Electrical compatibility is confirmed through identical current and voltage ratings. Mechanical compatibility depends on holder design. The substitute part's rectangular blade configuration must fit within the existing holder assembly. Physical dimension verification is required before installation.

Q: What is the primary reason for substitution?

A: The SPP-7K900 is classified as obsolete. The 170M6513 is an active product with current manufacturing availability and ongoing supplier support.

Q: Are there regulatory differences between these parts?

A: The 170M6513 carries CSA and UR approvals and is RoHS compliant. The SPP-7K900 regulatory status is not fully specified in available documentation. The substitute part provides enhanced regulatory alignment for applications requiring current compliance certifications.

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

A: Current rating (900A) and voltage rating (700V AC) are the primary electrical parameters. Both parts meet these specifications identically. Breaking capacity (200kA) and melting I²t (100000) are additional performance characteristics of the substitute part.

Q: Does the package change affect functionality?

A: The transition from fuse link to rectangular blade represents a form factor change. Electrical performance remains equivalent. Mechanical compatibility with the holder assembly must be confirmed through dimensional analysis and installation verification.
