Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN326-6-06 is determined by the following critical parameters:

• Connector Standard: IEC 320-C14 interface is mandatory for mechanical and electrical compatibility
• Current Rating: Minimum 6 A capacity required to match original specification
• Voltage Rating: 250VAC or higher to maintain safety margins in 250V applications
• Mounting Configuration: Panel mount with quick connect termination
• Filter Classification: EMI/RFI filtering capability at the component level
• Regulatory Compliance: Certifications from CSA, UL, or VDE to ensure safety and performance standards

The substitute part 858-06/018 from Qualtek meets these criteria through equivalent electrical ratings, identical connector interface, matching current capacity, and overlapping regulatory approvals.

Frequently Asked Questions (FAQ)

Q: Can the 858-06/018 directly replace the FN326-6-06 in existing installations?

A: Yes. Both components share identical IEC 320-C14 connector interfaces, 6 A current ratings, and 250VAC voltage specifications. The quick connect termination style is identical, enabling direct mechanical and electrical substitution without circuit modification.

Q: What is the significance of the FN326-6-06 being obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 858-06/018 provides an active-production alternative with equivalent electrical and mechanical specifications, ensuring continued availability for maintenance and replacement scenarios.

Q: Are the regulatory certifications equivalent between the two parts?

A: Both parts hold CSA and VDE certifications. The FN326-6-06 includes SEMKO and UR approvals, while the 858-06/018 includes UL approval. These certifications overlap in critical safety standards, ensuring compliance in applications requiring CSA or VDE validation.

Q: Does the 858-06/018 support the same frequency range as the FN326-6-06?

A: The 858-06/018 is specified as a filtered connector with EMI/RFI commercial-grade filtering. While the specific frequency range DC ~ 400MHz is not explicitly stated for the substitute, its EMI/RFI filtering classification indicates suitability for general-purpose power line applications equivalent to the original component.

Q: What is the panel cutout dimension requirement for the 858-06/018?

A: The 858-06/018 requires a rectangular panel cutout of 30.48mm x 22.86mm. Verify existing panel cutout dimensions before installation to confirm compatibility with the original FN326-6-06 mounting location.
