SPP-7E1100 Equivalent & Substitute Parts

Part Overview

The SPP-7E1100 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 1.1kA at 700V. This component is classified as obsolete, requiring identification of active equivalent parts for continued system support and procurement. The transition to substitute components is necessary due to product discontinuation and the need for reliable sourcing from active inventory.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-7E1100 is based on electrical parameter alignment and mechanical compatibility. The primary substitute, 170M6665, maintains the critical electrical specifications: 1.1kA current rating and 700VAC voltage rating. Both components are manufactured by Eaton - Bussmann Electrical Division, ensuring consistency in design standards and performance characteristics.

The key parameters determining substitution eligibility are:

• Current Rating: 1.1kA (identical)
• Voltage Rating: 700V AC (identical)
• Manufacturer: Eaton - Bussmann Electrical Division (same source)
• ECCN and HTSUS Classification: EAR99 and 8536.10.0040 (identical regulatory classification)

The 170M6665 differs in mounting configuration (bolt mount versus holder requirement) and package form factor (rectangular blade versus fuse link), but these represent mechanical variations that do not affect the core electrical function when properly integrated into the target application.

Parameter Comparison

Engineering Selection Recommendations

The 170M6665 is the designated substitute for the obsolete SPP-7E1100 based on electrical parameter equivalence. Both components share identical current and voltage ratings (1.1kA, 700V) and are manufactured by the same supplier, ensuring consistent performance standards.

The 170M6665 is classified as active product status with substantial inventory availability (5400 pieces), providing reliable long-term procurement support. The component carries identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.10.0040) and holds relevant certifications (CE, CSA, UR).

Selection of the 170M6665 requires mechanical integration assessment, as the bolt mount configuration and rectangular blade package differ from the original holder-based design. The application circuit must accommodate these physical variations to ensure proper installation and electrical continuity.

Frequently Asked Questions (FAQ)

Q: What are the critical electrical parameters for substitution? A: Current rating (1.1kA) and voltage rating (700V AC) are the primary electrical parameters determining substitution eligibility. The 170M6665 maintains both specifications identically to the SPP-7E1100.

Q: How do the mounting types differ between these components? A: The SPP-7E1100 requires a separate holder assembly for installation, while the 170M6665 uses bolt mount configuration. The application circuit design must accommodate the bolt mount interface of the substitute component.

Q: What is the significance of the breaking capacity specification? A: The 170M6665 specifies a breaking capacity of 200kA at rated voltage. This parameter indicates the maximum fault current the fuse can safely interrupt. The SPP-7E1100 breaking capacity is not provided in available documentation.

Q: Are there regulatory or compliance differences? A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M6665 holds CE, CSA, and UR certifications. No compliance barriers exist for substitution.

Q: Why is the 170M6665 recommended despite packaging differences? A: The 170M6665 is the only active equivalent part from Eaton - Bussmann Electrical Division with matching electrical specifications. The packaging difference (rectangular blade versus fuse link) is a mechanical consideration that must be addressed during circuit redesign or adapter integration.

Q: What is the Melting I²t value and why does it matter? A: The Melting I²t (190000 for the 170M6665) represents the thermal energy required to melt the fuse element. This parameter affects response time characteristics and thermal coordination with upstream protective devices in the electrical system.
