SPP-4E100 Equivalent & Substitute Parts

Part Overview

The SPP-4E100 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 parts for continued system support and procurement. The part requires a dedicated holder for installation and is part of the Semitron™ SPP series. Due to its obsolete status, sourcing active alternatives is necessary for maintenance and new installations.

Key Parameters

Substitute Part Grouping Explanation

The 170M3662 qualifies as a functional equivalent based on the following critical parameters:

• Current Rating: Both parts rated at 100A
• Voltage Rating: Both parts rated at 700V (AC)
• Manufacturer: Same manufacturer (Eaton - Bussmann Electrical Division)
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS classifications
• Moisture Sensitivity: Both parts have compatible MSL ratings

The primary difference is the mounting configuration: SPP-4E100 uses a blade-type fuse link requiring a separate holder, while 170M3662 employs bolt mount with a rectangular/square form factor. This distinction affects installation methodology but does not alter the electrical protection characteristics at the specified current and voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

The 170M3662 is an active product suitable for replacing the obsolete SPP-4E100 in applications requiring 100A protection at 700V. Both components share identical electrical ratings and regulatory classifications. The 170M3662 carries active product status with CSA and UR approvals, ensuring continued availability and compliance support.

Selection of the 170M3662 requires verification that the bolt mount configuration is compatible with the existing installation framework. The transition from blade-type fuse link to square bolt mount necessitates mechanical integration assessment within the target circuit protection assembly.

Frequently Asked Questions (FAQ)

Q: Can the 170M3662 directly replace the SPP-4E100 without modification?

A: Both parts provide identical electrical protection at 100A and 700V. However, the mounting interface differs: SPP-4E100 uses a blade fuse link requiring a separate holder, while 170M3662 employs bolt mount. Installation compatibility depends on the existing holder or mounting bracket design.

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

A: Current rating (100A), voltage rating (700V), and manufacturer (Eaton - Bussmann Electrical Division) are the primary criteria. Both parts meet these specifications and share identical regulatory classifications (ECCN EAR99, HTSUS 8536.10.0040).

Q: Why is the SPP-4E100 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 170M3662 remains in active production, providing a supported alternative for ongoing procurement and system maintenance.

Q: Are there compliance differences between these parts?

A: Both parts are REACH Unaffected and classified under EAR99. The 170M3662 carries RoHS Compliant status with CSA and UR approvals, providing additional regulatory documentation for industrial applications.

Q: What is the significance of the 200kA breaking capacity specification on the 170M3662?

A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt. This specification is provided for the 170M3662 but not documented for the obsolete SPP-4E100. Verify that 200kA breaking capacity meets the fault current requirements of your circuit protection design.
