Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN376-6-22 is based on strict electrical and mechanical parameter alignment within the FN 370 series. The primary substitute, FN378-6-22, maintains compatibility through the following critical parameters:

• Identical connector style (IEC 320-C14) and type (Receptacle, Male Blades - Module)
• Matching number of positions (3)
• Identical filter type and current rating (Filtered, 6A)
• Identical mounting configuration (Panel Mount, Flange)
• Matching termination method (Quick Connect)
• Compatible panel thickness range (0.031" ~ 0.126")
• Equivalent material flammability rating (UL94 V-2)
• Identical ingress protection rating (IP40)
• Equivalent regulatory approvals (CSA, UL, VDE)

The FN378-6-22 differs only in product status (active versus obsolete) and packaging format (tray versus unspecified), with no functional or electrical parameter deviations.

Parameter Comparison

Engineering Selection Recommendations

The FN378-6-22 is the direct functional equivalent for the obsolete FN376-6-22. Selection of the FN378-6-22 is supported by:

• Active product status ensuring continued availability and manufacturing support
• Identical electrical and mechanical specifications across all critical parameters
• Equivalent regulatory compliance (CSA, UL, VDE certifications maintained)
• Matching RoHS compliance status (both compliant)
• Identical REACH and ECCN classifications
• Tray packaging format suitable for standard procurement and inventory management

No functional redesign or circuit modification is required when transitioning from FN376-6-22 to FN378-6-22.

Frequently Asked Questions (FAQ)

Q: Can FN378-6-22 be used as a direct replacement for FN376-6-22?

A: Yes. The FN378-6-22 maintains identical electrical and mechanical specifications, including connector style, current rating, mounting configuration, and regulatory approvals. No design changes are necessary.

Q: What is the primary difference between these parts?

A: The FN376-6-22 is obsolete, while the FN378-6-22 is active. The FN378-6-22 is supplied in tray packaging. All functional parameters are equivalent.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts accommodate variable size panel cutouts and support the same panel thickness range of 0.031" to 0.126" (0.79mm to 3.20mm).

Q: Do both parts support the same fuse configuration?

A: Both parts accommodate a fuse (fuse not included). The FN378-6-22 specifies twin fused capability, providing enhanced flexibility in fuse holder configuration.

Q: Are regulatory certifications equivalent?

A: Yes. Both parts carry identical approvals from CSA, UL, and VDE, with matching UL94 V-2 material flammability ratings and IP40 ingress protection.

Q: What is the current rating for the filter stage?

A: Both parts are rated for 6A at the filter stage, suitable for commercial EMI/RFI filtered power entry applications.
