SPP-5E250 Equivalent & Substitute Parts

Part Overview

The SPP-5E250 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 250A at 700V operation. This component is classified as obsolete and requires a holder for installation. The part is designed for electrical and industrial applications where high-current protection is necessary. Due to its obsolete status, identification of functionally equivalent substitute components is essential for system maintenance, repair, and continued operational support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-5E250 is based on electrical and mechanical compatibility parameters. The primary criteria for substitution are:

Electrical Parameters:

• Current Rating: 250A
• Voltage Rating: 700V AC

Mechanical Parameters:

• Mounting compatibility with existing holder infrastructure
• Physical form factor suitable for installation

Compliance Parameters:

• REACH compliance status
• ECCN classification
• HTSUS code alignment

The substitute part 170M4659 shares the same current rating (250A), voltage rating (700VAC), manufacturer (Eaton - Bussmann Electrical Division), and regulatory classification (ECCN EAR99, HTSUS 8536.10.0040). The primary difference is the mounting type transition from holder-based to bolt mount configuration, which represents a mechanical interface change rather than an electrical incompatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Substitution:

The 170M4659 is electrically equivalent to the SPP-5E250 based on matching current rating (250A) and voltage rating (700V). Both components are manufactured by Eaton - Bussmann Electrical Division and share identical ECCN and HTSUS classifications, confirming regulatory alignment.

Status Consideration:

The SPP-5E250 is obsolete, while the 170M4659 is active. Selection of the active substitute part ensures continued availability and supply chain reliability for future maintenance cycles.

Compliance and Certification:

The 170M4659 carries CE, CSA, and UR approvals and is RoHS compliant, providing enhanced regulatory coverage compared to the obsolete SPP-5E250. Both parts maintain EAR99 export classification.

Mechanical Interface:

The transition from holder-based mounting (SPP-5E250) to bolt mount configuration (170M4659) requires verification of installation infrastructure compatibility. The physical dimensions of the 170M4659 (5.354" L x 2.087" W x 2.717" H) must be confirmed against available mounting space and bolt hole patterns in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 170M4659 directly replace the SPP-5E250 without modification?

A: Electrical substitution is valid based on matching current and voltage ratings. However, the mounting type differs: SPP-5E250 requires a holder, while 170M4659 uses bolt mount. Installation infrastructure must accommodate the bolt mount configuration.

Q: Are there any electrical performance differences between these parts?

A: Both parts are rated for 250A at 700V. The 170M4659 provides additional specifications: 200kA breaking capacity and 3100 melting I²t. These parameters were not specified for the SPP-5E250.

Q: What is the significance of the obsolete status of SPP-5E250?

A: Obsolete status indicates the part is no longer manufactured. The active status of 170M4659 ensures ongoing availability and supply chain support for future procurement and replacement needs.

Q: Are both parts compliant with current regulatory standards?

A: Both parts share EAR99 ECCN classification and 8536.10.0040 HTSUS code. The 170M4659 additionally carries CE, CSA, and UR certifications and is RoHS compliant, providing broader regulatory coverage.

Q: What are the physical dimension differences?

A: The 170M4659 dimensions are 5.354" L x 2.087" W x 2.717" H (136.00mm x 53.00mm x 69.00mm). SPP-5E250 dimensions were not provided. Verification against available installation space is required.

Q: Is moisture sensitivity a concern for either part?

A: SPP-5E250 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. 170M4659 lists MSL as Not Applicable. Both parts are suitable for standard industrial storage and handling conditions.
