SPP-4H100 Equivalent & Substitute Parts

Part Overview

The SPP-4H100 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 100A at 700V operation. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for system maintenance, repair, and continued operational support where original inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SPP-4H100 is determined by alignment of the following critical electrical and mechanical parameters:

• Current Rating: 100A
• Voltage Rating: 700V (AC)
• Manufacturer: Eaton - Bussmann Electrical Division
• Regulatory Compliance: ECCN EAR99, HTSUS 8536.10.0040

The substitute part 170M3762 meets these core requirements. While the mounting configuration differs (bolt mount versus holder-based), both components operate within the same electrical specification envelope and are manufactured by the same supplier, ensuring compatibility within systems designed for 100A/700V fuse protection.

Parameter Comparison

Engineering Selection Recommendations

The 170M3762 serves as the active substitute for the obsolete SPP-4H100. Both components share identical electrical ratings (100A, 700V) and are manufactured by Eaton - Bussmann Electrical Division under the same regulatory classification (ECCN EAR99, HTSUS 8536.10.0040).

The 170M3762 is currently in active production status with 868 units available in inventory, whereas the SPP-4H100 is obsolete with limited remaining stock (736 units). The substitute part includes documented breaking capacity (200kA) and melting I²t characteristics (360), providing enhanced specification transparency for system design validation.

Installation requires mechanical accommodation for the bolt mount configuration of the 170M3762 in place of the holder-based mounting of the original SPP-4H100. This substitution is appropriate for new installations and system upgrades where mounting infrastructure can be adapted to the rectangular bolt mount form factor.

Frequently Asked Questions (FAQ)

Q: Can the 170M3762 directly replace the SPP-4H100 without modification?

A: Both components meet the same electrical requirements (100A, 700V). However, the mounting configuration differs: the SPP-4H100 requires a holder, while the 170M3762 uses bolt mount. Installation requires mechanical adaptation to accommodate the different mounting method.

Q: What is the significance of the obsolete status of the SPP-4H100?

A: Obsolete status indicates the part is no longer manufactured. The 170M3762 is an active product from the same manufacturer, ensuring continued availability and supply chain reliability for future maintenance and replacement needs.

Q: Are there compliance differences between the two parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M3762 carries RoHS Compliant certification, whereas the SPP-4H100 specification does not document RoHS status.

Q: What is the breaking capacity significance?

A: The 170M3762 specifies a breaking capacity of 200kA at rated voltage. This parameter defines the maximum fault current the fuse can safely interrupt. The SPP-4H100 breaking capacity is not provided in available documentation.

Q: How do the physical dimensions compare?

A: The 170M3762 dimensions are 1.969" L x 1.772" W x 2.323" H (50.00mm x 45.00mm x 59.00mm). The SPP-4H100 dimensions are not specified. Physical form factor differences reflect the distinct mounting approaches (bolt mount versus holder-based).
