Key Parameters

Substitute Part Grouping Explanation

The 170M4614 serves as an electrical equivalent to the SPP-5B500 based on the following critical parameters:

• Current Rating: Both components are rated for 500A
• Voltage Rating: Both components are rated for 700V AC
• Manufacturer: Both are manufactured by Eaton - Bussmann Electrical Division
• Regulatory Compliance: Both share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications
• Moisture Sensitivity: Both maintain MSL 1 or equivalent non-applicable status

The primary difference lies in mounting configuration: the SPP-5B500 requires a separate holder, while the 170M4614 features bolt mount construction. This mechanical difference does not affect electrical substitution where mounting infrastructure can be adapted.

Parameter Comparison

Engineering Selection Recommendations

The 170M4614 is the designated substitute for the obsolete SPP-5B500 based on electrical parameter equivalence. Both components share identical current and voltage ratings (500A, 700V) and are manufactured by the same supplier, ensuring functional compatibility in electrical circuits.

The 170M4614 holds active product status with current manufacturing support, whereas the SPP-5B500 is obsolete. The substitute component carries CE, CSA, and UR approvals and is RoHS compliant, meeting modern regulatory requirements.

Mechanical integration requires evaluation of the mounting infrastructure. The SPP-5B500 operates within a holder-based system, while the 170M4614 uses bolt mount construction. System redesign or adapter implementation may be necessary depending on existing installation geometry.

Frequently Asked Questions (FAQ)

Q: Can the 170M4614 directly replace the SPP-5B500 in existing installations?

A: Electrical substitution is valid based on identical current (500A) and voltage (700V) ratings. Mechanical compatibility depends on the mounting infrastructure. Holder-based systems require adaptation to accommodate the bolt mount design of the 170M4614.

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

A: Current rating, voltage rating, and breaking capacity at rated voltage are the primary electrical parameters. Mounting type and physical dimensions determine mechanical compatibility. Both the SPP-5B500 and 170M4614 maintain identical electrical specifications.

Q: Why is the SPP-5B500 listed as obsolete?

A: The SPP-5B500 is no longer in active production. The 170M4614 represents the current equivalent offering from Eaton - Bussmann Electrical Division for this electrical specification.

Q: Are there compliance differences between these components?

A: The 170M4614 carries CE, CSA, and UR certifications and is RoHS compliant. Both components share identical ECCN and HTSUS classifications. The substitute component meets current regulatory standards for electrical distribution systems.

Q: What is the melting I²t specification, and why does it matter?

A: The melting I²t value (25000.0 for the 170M4614) indicates the thermal energy required to melt the fuse element. This parameter affects response time and thermal coordination in circuit protection schemes. Specification availability for the substitute component provides additional design verification data.
