SPP-4H175 Equivalent & Substitute Parts

Part Overview

The SPP-4H175 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated at 175A with a 700V voltage rating. This component is classified as obsolete, requiring identification of suitable alternatives for continued system support and procurement planning. The obsolete status necessitates substitute part evaluation to maintain electrical system integrity and operational continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-4H175 is based on the following critical electrical and mechanical parameters:

• Voltage Rating: 700V AC compatibility
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer ensures design consistency)
• Mounting compatibility: Holder-based or bolt-mount configurations
• Current protection characteristics: Fuse class and response time alignment
• Regulatory compliance: REACH and ECCN classification alignment

The substitute part 170M3765 shares the same voltage rating (700V), manufacturer, and regulatory classification. However, the current rating differs (200A vs. 175A), and the mounting type transitions from holder-based to bolt-mount configuration. These differences require engineering evaluation for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

The 170M3765 represents an active product alternative from the same manufacturer with matching voltage rating and regulatory classification. Selection of this substitute requires verification that:

• The 200A current rating is appropriate for the circuit protection requirement (higher than the original 175A rating)
• The bolt-mount configuration is compatible with existing holder or mounting infrastructure
• The rectangular blade package accommodates the mechanical installation space

The active product status of 170M3765 ensures ongoing availability and compliance with current manufacturing standards, including RoHS compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the 170M3765 directly replace the SPP-4H175 in existing installations?

A: Direct replacement requires verification of mounting compatibility. The SPP-4H175 uses a holder-based configuration, while the 170M3765 employs bolt-mount design. Mechanical integration must be confirmed before substitution.

Q: What is the significance of the current rating difference (175A vs. 200A)?

A: The 170M3765 provides higher current protection at 200A compared to the original 175A rating. This difference affects circuit protection characteristics and must be evaluated against the specific application's current requirements.

Q: Are both parts compliant with the same regulatory standards?

A: Both parts share EAR99 ECCN classification. The 170M3765 carries RoHS Compliant certification, while the SPP-4H175 status is not specified in available data. Both maintain compatibility with 700V voltage systems.

Q: Why is the SPP-4H175 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured. The 170M3765 active status provides a path for continued procurement and system support.

Q: What are the package differences between these parts?

A: The SPP-4H175 uses a fuse link package requiring a holder assembly. The 170M3765 employs a rectangular blade package with bolt-mount configuration, resulting in different mechanical footprints and installation requirements.
