SPP-6B500 Equivalent & Substitute Parts

Part Overview

The SPP-6B500 is a fuse link rated for 500A at 700V, manufactured by Eaton - Bussmann Electrical Division as part of the Semitron™ SPP series. This component is classified as obsolete and requires a holder for installation. Due to its obsolete status, identifying equivalent substitute parts is essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

The 170M5610 qualifies as a substitute based on the following matching electrical and mechanical parameters:

• Current Rating: 500A (identical)
• Voltage Rating: 700VAC (equivalent to 700V)
• Manufacturer: Eaton - Bussmann Electrical Division (same manufacturer)
• HTSUS Code: 8536.10.0040 (identical classification)
• ECCN: EAR99 (identical export classification)

The primary difference is the mounting configuration: the SPP-6B500 uses a blade-type fuse link requiring a holder, while the 170M5610 employs a square bolt mount configuration. This distinction requires verification of holder compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

The 170M5610 is an active product from the same manufacturer with identical electrical ratings (500A, 700VAC). It carries current regulatory compliance certifications (CE, CSA, UR) and RoHS compliance status, making it suitable for new installations and replacements where regulatory requirements apply.

The SPP-6B500, being obsolete, should be replaced with the 170M5610 in applications where the mounting configuration can be accommodated. The transition from blade-type holder mounting to bolt mount configuration requires physical integration assessment within the target equipment.

Frequently Asked Questions (FAQ)

Q: Can the 170M5610 directly replace the SPP-6B500 in existing equipment?

A: Both components share identical electrical ratings (500A, 700VAC) and are manufactured by the same company. However, the mounting interface differs: SPP-6B500 uses blade-type fuse link mounting, while 170M5610 uses bolt mount configuration. Direct replacement requires compatibility with the existing holder or mounting structure.

Q: What are the key electrical parameters for substitution?

A: Current rating (500A) and voltage rating (700VAC) are the primary electrical parameters determining substitution eligibility. Both parts meet these specifications identically.

Q: Why is the SPP-6B500 listed as obsolete?

A: The SPP-6B500 is classified as obsolete by the manufacturer. The 170M5610 represents the active equivalent product line from Eaton - Bussmann Electrical Division.

Q: Are there compliance differences between these parts?

A: The 170M5610 carries CE, CSA, and UR certifications and is RoHS compliant. The SPP-6B500 specifications do not include these certifications. For applications requiring specific regulatory compliance, the 170M5610 is the appropriate selection.

Q: What is the significance of the different fuse types (Blade vs. Square)?

A: Fuse type designation reflects the physical form factor and mounting method. The blade type requires a compatible holder, while the square type uses bolt mount configuration. Selection depends on the mechanical interface available in the target application.
