Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPP-6M600 is determined by the following critical parameters:

• Voltage Rating: Must match or exceed 700V AC operation
• Current Rating: The substitute 170M5562 operates at 630A, which is within the same electrical class and voltage family
• Mounting Configuration: Both parts require a holder for installation, ensuring mechanical compatibility
• Manufacturer Continuity: Both parts are manufactured by Eaton - Bussmann Electrical Division, maintaining supply chain consistency
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications

The 170M5562 is classified as an active product with current manufacturing support, making it a viable substitute for the obsolete SPP-6M600 within the same electrical and mechanical framework.

Parameter Comparison

Engineering Selection Recommendations

The 170M5562 serves as the designated substitute for the obsolete SPP-6M600 based on the following criteria:

• Active Product Status: The 170M5562 is actively manufactured and supported, ensuring long-term availability and supply chain reliability
• Voltage and Current Compatibility: Both components operate within the 700V AC electrical class, with the 170M5562 rated at 630A, maintaining electrical performance within the same operational envelope
• Regulatory Alignment: Both parts share identical export control (EAR99) and tariff classifications (8536.10.0040), simplifying procurement and compliance documentation
• Certification and Approval: The 170M5562 carries CSA and UR approvals, providing third-party validation for industrial and electrical applications
• Environmental Compliance: The 170M5562 is RoHS Compliant, meeting modern environmental and material restriction standards

Frequently Asked Questions (FAQ)

Q: Can the 170M5562 directly replace the SPP-6M600 in existing installations?

A: The 170M5562 is electrically and mechanically compatible within the 700V AC voltage class. Both components require a holder for installation. However, physical form factor differences exist: the SPP-6M600 is a stud-type fuse link, while the 170M5562 is a square rectangular blade type. Verify that the existing holder accommodates the rectangular blade configuration before installation.

Q: What is the significance of the current rating difference (600A vs. 630A)?

A: The 170M5562 operates at 630A, which is 30A higher than the SPP-6M600. This represents operation within the same electrical class and voltage family. The higher current rating does not compromise compatibility; however, circuit design parameters should be reviewed to confirm that the 630A rating aligns with system protection requirements.

Q: Are there any compliance or certification differences between these parts?

A: The 170M5562 carries CSA and UR approvals and is RoHS Compliant. The SPP-6M600 specifications do not include these certifications in the provided data. The 170M5562's active product status and modern certifications make it suitable for applications requiring current regulatory compliance.

Q: What is the breaking capacity of the SPP-6M600?

A: Breaking capacity data for the SPP-6M600 is not provided in the available specifications. The 170M5562 has a breaking capacity of 200kA at rated voltage. Consult original Eaton - Bussmann documentation for SPP-6M600 breaking capacity specifications if this parameter is critical for your application.

Q: How do the physical dimensions affect substitution?

A: The 170M5562 dimensions are 1.969" L x 2.402" W x 3.031" H (50.00mm x 61.00mm x 77.00mm). The SPP-6M600 dimensions are not specified. Holder compatibility must be verified based on the rectangular blade form factor of the 170M5562 before installation.
