SPP-6K500 Equivalent & Substitute Parts

Part Overview

The SPP-6K500 is a fuse link manufactured by Eaton - Bussmann Electrical Division, rated for 500A at 700V operation. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement applications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 170M5510 is qualified as an equivalent based on the following critical parameters:

• Current Rating: 500A (identical)
• Voltage Rating: 700VAC (identical)
• Mounting Type: Requires Holder (identical)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer)
• ECCN Classification: EAR99 (identical)
• HTSUS Code: 8536.10.0040 (identical)

The primary difference is the fuse form factor: the SPP-6K500 is a stud-type fuse link, while the 170M5510 is a square/rectangular blade fuse. Both require external holders and operate within the same electrical parameters, making them functionally interchangeable within systems designed to accommodate the rectangular blade form factor.

Parameter Comparison

Engineering Selection Recommendations

The 170M5510 is an active product from the same manufacturer with identical electrical ratings (500A, 700VAC). Selection of this substitute is supported by:

• Matching current and voltage specifications
• Same manufacturer ensuring design consistency
• Active product status providing ongoing availability
• RoHS compliance status
• Identical export classification and tariff codes

The primary consideration for substitution is mechanical compatibility: the rectangular blade form factor of the 170M5510 requires a holder designed for this geometry, whereas the SPP-6K500 uses a stud configuration. System integration must account for this form factor difference.

Frequently Asked Questions (FAQ)

Q: Can the 170M5510 directly replace the SPP-6K500?

A: Electrical substitution is valid based on identical current (500A) and voltage (700VAC) ratings. Mechanical compatibility depends on the holder design. The SPP-6K500 stud configuration differs from the 170M5510 rectangular blade form factor.

Q: What are the critical parameters for fuse substitution in this category?

A: Current rating, voltage rating, and mounting type are the primary parameters. Both parts maintain 500A at 700V operation and require external holders. The form factor difference (stud vs. rectangular blade) is a secondary consideration affecting physical installation.

Q: Why is the SPP-6K500 obsolete?

A: Product status is listed as obsolete. The 170M5510 represents an active alternative from the same manufacturer with equivalent electrical specifications.

Q: Are there compliance differences between these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications. The 170M5510 carries RoHS compliance certification, whereas the SPP-6K500 status is not specified.

Q: What is the melting I²t specification used for?

A: The melting I²t value (21500 for the 170M5510) characterizes the thermal energy required to melt the fuse element. This parameter is provided for the substitute part but not specified for the obsolete SPP-6K500.
