Key Parameters

Substitute Part Grouping Explanation

The 170M6613 qualifies as a functional substitute based on the following critical parameters:

• Current Rating Match: Both parts are rated for 900A operation
• Voltage Rating Match: Both parts operate at 700V AC
• Manufacturer Consistency: Both manufactured by Eaton - Bussmann Electrical Division
• Product Status Advantage: 170M6613 is active, ensuring ongoing availability and support
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications
• Environmental Classification: Both maintain REACH Unaffected status

The primary distinction lies in mounting configuration: SPP-7B900 uses a blade-type fuse link requiring a holder, while 170M6613 employs bolt mount with a square rectangular form factor. This difference necessitates mechanical integration review during substitution.

Parameter Comparison

Engineering Selection Recommendations

The 170M6613 is the designated substitute for SPP-7B900 based on electrical parameter equivalence and active product status. Selection of 170M6613 provides:

• Continued availability through active manufacturing status
• Identical current and voltage ratings ensuring electrical compatibility
• Consistent regulatory classification (ECCN EAR99, HTSUS 8536.10.0040)
• Enhanced performance data including 200kA breaking capacity and 100000 melting I²t specifications
• CSA, CE, and UR approval certifications supporting industrial and electrical applications

Mechanical integration requires evaluation of the mounting transition from blade-type holder-based installation to bolt mount configuration. Physical dimensions of 170M6613 (2.008" L x 2.992" W x 3.622" H) must be verified against available mounting space and holder compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can SPP-7B900 and 170M6613 be used interchangeably without modification?

A: Both parts share identical electrical ratings (900A, 700V AC). However, mounting configuration differs: SPP-7B900 requires a dedicated holder with blade-type connection, while 170M6613 uses bolt mount with square rectangular form factor. Mechanical integration assessment is required before substitution.

Q: Why is SPP-7B900 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M6613 active status ensures ongoing procurement availability and manufacturer support for this electrical specification class.

Q: What are the key electrical parameters that make 170M6613 equivalent to SPP-7B900?

A: Current rating (900A), voltage rating (700V AC), and manufacturer (Eaton - Bussmann Electrical Division) are the primary equivalence criteria. Both parts maintain identical regulatory classifications (ECCN EAR99, HTSUS 8536.10.0040).

Q: Does 170M6613 provide additional performance specifications?

A: Yes. 170M6613 includes documented breaking capacity (200kA @ rated voltage) and melting I²t (100000), specifications not provided for SPP-7B900. These parameters support enhanced application analysis and safety verification.

Q: Are there environmental or compliance differences between these parts?

A: Both parts share REACH Unaffected status and identical ECCN/HTSUS classifications. 170M6613 carries CSA, CE, and UR approvals, supporting industrial and electrical applications across multiple regulatory jurisdictions.

Q: What physical dimensions should be considered during substitution?

A: 170M6613 dimensions are 2.008" L x 2.992" W x 3.622" H (51.00mm x 76.00mm x 92.00mm). Verify these dimensions against available mounting space and holder compatibility in the target installation.
