Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7B1100 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 1.1kA (must match exactly)
• Voltage Rating: 700V AC (must match exactly)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design compatibility)
• Regulatory Compliance: REACH Unaffected and EAR99 classification maintained across substitutes

The substitute part 170M6615 meets these core electrical requirements. However, the mounting configuration differs: the SPP-7B1100 uses blade-type holder mounting, while the 170M6615 employs bolt mount configuration. This mechanical difference requires evaluation of the installation environment and holder compatibility before substitution.

Parameter Comparison

Engineering Selection Recommendations

The 170M6615 provides electrical equivalence to the SPP-7B1100 with identical current and voltage ratings from the same manufacturer. The substitute part carries active product status with current availability (5200 pcs in stock versus 1011 pcs for the obsolete SPP-7B1100), ensuring long-term supply reliability.

The 170M6615 holds multiple regulatory approvals (CE, CSA, UR) and RoHS compliance, meeting modern environmental and safety standards. Both parts maintain EAR99 export classification and REACH compliance status.

The primary consideration for substitution is the mechanical mounting interface: the SPP-7B1100 requires a blade-type holder, while the 170M6615 uses bolt mount configuration. Selection of the 170M6615 requires confirmation that the installation environment supports bolt mount installation or that appropriate adapter hardware is available.

Frequently Asked Questions (FAQ)

Q: Can the 170M6615 directly replace the SPP-7B1100 in existing installations?

A: Electrical compatibility is confirmed (1.1kA, 700V). Mechanical compatibility depends on the holder type in your installation. The SPP-7B1100 uses blade mounting, while the 170M6615 uses bolt mount. Direct physical substitution requires compatible mounting hardware.

Q: What are the key electrical parameters that must match for substitution?

A: Current rating (1.1kA) and voltage rating (700V AC) must match exactly. Both parts meet these requirements. The breaking capacity (200kA for 170M6615) and melting I²t (190000.0 for 170M6615) provide additional performance data for the substitute.

Q: Why is the SPP-7B1100 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M6615 is an active product with current manufacturing and distribution, making it the preferred long-term sourcing option.

Q: Are there compliance differences between these parts?

A: The 170M6615 carries CE, CSA, and UR approvals plus RoHS compliance. Both parts maintain EAR99 export classification. The substitute meets current regulatory requirements for industrial and electrical applications.

Q: What is the inventory situation for each part?

A: SPP-7B1100 has 1011 pcs available (obsolete status). 170M6615 has 5200 pcs available (active product). The substitute offers significantly better availability for ongoing supply needs.
