Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-6F375 is based on the following critical parameters:

• Current Rating: 375A nominal capacity
• Voltage Rating: 700V operation
• Fuse Type & Mounting: Blade configuration with holder requirement
• Manufacturer Continuity: Eaton - Bussmann Electrical Division maintains product line compatibility
• Regulatory Compliance: REACH and ECCN classification alignment

The substitute part 170M5708 is identified as an equivalent option based on manufacturer designation and electrical parameter compatibility within the Eaton - Bussmann product portfolio.

Parameter Comparison

Engineering Selection Recommendations

The SPP-6F375 is obsolete; therefore, substitute part identification is necessary for continued system support. The 170M5708 is designated as an equivalent substitute by the manufacturer Eaton - Bussmann Electrical Division and shares the same ECCN (EAR99) and HTSUS classification (8536.10.0040).

Key considerations for selection:

• Active Product Status: The 170M5708 maintains active product status, ensuring ongoing availability and manufacturer support.
• Regulatory Compliance: Both parts comply with REACH requirements and share identical export classification codes.
• Electrical Parameters: Current and voltage ratings differ between the two parts; application-specific circuit requirements must be evaluated against the substitute specifications.
• Mounting Configuration: The SPP-6F375 requires a holder, while the 170M5708 uses bolt mount configuration; mechanical integration must be assessed for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 170M5708 directly replace the SPP-6F375 in all applications?

A: Direct replacement depends on circuit design parameters. The 170M5708 has a higher current rating (400A vs. 375A) and significantly lower voltage rating (70 VAC vs. 700V). Electrical circuit compatibility must be confirmed before substitution.

Q: What is the primary reason for seeking a substitute for the SPP-6F375?

A: The SPP-6F375 is classified as obsolete. Substitute identification is necessary for maintenance, repair, and system continuity when original inventory is exhausted.

Q: Are there mechanical compatibility concerns between these parts?

A: Yes. The SPP-6F375 requires a holder for installation, while the 170M5708 uses bolt mount configuration. Mechanical integration into the target system must be evaluated independently.

Q: Do both parts meet the same regulatory standards?

A: Both parts share identical ECCN (EAR99) and HTSUS codes (8536.10.0040), indicating equivalent export and tariff classification. The 170M5708 is RoHS Compliant; RoHS status for the SPP-6F375 is not specified in available data.

Q: What is the inventory status of these parts?

A: SPP-6F375 inventory is listed as 703 pieces (new original, in stock). The 170M5708 has 946 pieces available (new original, bulk packaging, in stock).
