SPP-4F100 Equivalent & Substitute Parts

Part Overview

The SPP-4F100 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 100A at 700V operation. This component is classified as obsolete, requiring identification of active equivalent alternatives for continued system support and procurement. The part operates as a blade-mounted fuse element designed for electrical protection in industrial applications. Locating suitable substitutes is essential for maintaining system functionality and ensuring compliance with current component availability standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-4F100 is determined by alignment of critical electrical and mechanical parameters:

Electrical Parameters: Current rating (100A) and voltage rating (700V AC) must match or exceed the original specification to maintain protective function and system compatibility.

Mechanical Parameters: Mounting configuration and physical form factor determine physical fit within existing holder assemblies. The SPP-4F100 requires a dedicated holder; substitute parts must be compatible with the same mounting infrastructure.

Compliance Parameters: ECCN classification (EAR99) and REACH status ensure regulatory consistency. Active product status is preferred to guarantee long-term availability and support.

The substitute part 170M3712 satisfies these criteria through equivalent current and voltage ratings, shared manufacturer origin, and active product status, despite differing in mounting style (bolt mount versus blade mount requiring holder).

Parameter Comparison

Engineering Selection Recommendations

The 170M3712 serves as the primary substitute for the obsolete SPP-4F100 based on the following factors:

Electrical Equivalence: Both components maintain identical current (100A) and voltage (700V AC) ratings, ensuring equivalent protective performance within the electrical circuit.

Manufacturer Continuity: Both parts originate from Eaton - Bussmann Electrical Division, maintaining design consistency and quality standards.

Regulatory Compliance: Both components share EAR99 ECCN classification and equivalent compliance profiles, supporting seamless integration into regulated procurement workflows.

Active Availability: The 170M3712 holds active product status with documented inventory (1184 units), ensuring reliable procurement compared to the obsolete SPP-4F100.

Mechanical Consideration: The 170M3712 employs bolt mount configuration rather than blade mount with holder. System integration requires verification that the mounting infrastructure can accommodate this alternative form factor.

Frequently Asked Questions (FAQ)

Q: Can the 170M3712 directly replace the SPP-4F100 without modification?

A: Electrical parameters are equivalent (100A, 700V AC). However, the 170M3712 uses bolt mount configuration while the SPP-4F100 requires a blade holder. Physical installation requires compatible mounting infrastructure. Mechanical adaptation may be necessary depending on existing system design.

Q: What are the key parameters that determine substitution eligibility?

A: Current rating (100A), voltage rating (700V AC), and manufacturer origin (Eaton - Bussmann) are the primary electrical criteria. Mounting type and form factor determine physical compatibility with existing holder or mounting assemblies.

Q: Why is the SPP-4F100 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M3712 represents the active alternative within the Eaton - Bussmann product line for equivalent electrical protection requirements.

Q: Are there compliance differences between these parts?

A: Both components share EAR99 ECCN classification. The 170M3712 includes CSA and UR approvals, providing additional third-party certification. REACH status remains consistent across both parts.

Q: What is the significance of the 200kA breaking capacity specification?

A: The 170M3712 specifies 200kA breaking capacity at rated voltage, indicating the maximum fault current the fuse can safely interrupt. This specification is not provided for the SPP-4F100 but represents standard performance data for the substitute component.
