Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN376-2-21 is determined by the following critical parameters:

• Connector Style & Type: Must be IEC 320-C14 Receptacle, Male Blades - Module configuration
• Mounting Configuration: Panel Mount, Flange mounting required
• Number of Positions: 3-position requirement
• Termination Method: Quick Connect termination compatibility
• Fuse Accommodation: Must support fuse holder installation
• Panel Compatibility: Panel thickness range 0.031" ~ 0.126" (0.79mm ~ 3.20mm)
• Regulatory Compliance: CSA, UL, VDE approvals required
• Filtering Capability: EMI/RFI filtering at commercial grade

The identified substitute parts FN378-2-21 and 864-10/011 satisfy these core substitution criteria, though with variations in current rating and additional features.

Parameter Comparison

Engineering Selection Recommendations

FN378-2-21 (Schaffner EMC Inc.)

This substitute is the primary equivalent for FN376-2-21 replacement. Both parts share identical connector style, mounting configuration, and regulatory approvals. FN378-2-21 is Active status with ROHS3 compliance, providing long-term availability. The primary difference is the reduced current rating of 2A versus the original 10A. This part is suitable for applications where the lower current specification meets system requirements. The twin fused fuse holder configuration provides enhanced circuit protection capability.

864-10/011 (Qualtek)

This substitute provides functional equivalence with IEC 320-C14 configuration and panel mount flange design. It maintains CSA, UL, VDE regulatory compliance and Active product status. The 864-10/011 includes an integrated On-Off switch feature not present in the original part, and specifies 4/6A appliance inlet current rating with 250VAC voltage rating. This part is suitable for applications requiring switch functionality and lower current specifications. Panel cutout dimensions are specified as Rectangular - 28.96mm x 60.20mm.

Selection between FN378-2-21 and 864-10/011 depends on current rating requirements and whether integrated switch functionality is needed in the application.

Frequently Asked Questions (FAQ)

Q: Can FN378-2-21 directly replace FN376-2-21 in all applications?

A: FN378-2-21 maintains identical connector style, mounting type, and regulatory approvals. However, the current rating is reduced from 10A to 2A. Direct replacement is valid only for applications where 2A current capacity is sufficient.

Q: What is the primary difference between FN376-2-21 and FN378-2-21?

A: Both parts are Schaffner EMC Inc. FN 370 series IEC 320-C14 panel mount receptacles with identical mechanical and electrical interfaces. The main difference is current rating (10A vs. 2A) and fuse holder configuration (single vs. twin fused). FN378-2-21 is Active status while FN376-2-21 is Obsolete.

Q: Is 864-10/011 compatible with existing FN376-2-21 panel cutouts?

A: 864-10/011 specifies a rectangular panel cutout of 28.96mm x 60.20mm. Compatibility depends on the original panel cutout dimensions. Both parts use Panel Mount, Flange configuration with IEC 320-C14 connectors, but physical cutout verification is required before installation.

Q: Do all substitute parts support fuse installation?

A: Yes. FN376-2-21, FN378-2-21, and 864-10/011 all accommodate fuse holders. Fuses are not included with any part and must be sourced separately according to application requirements.

Q: What regulatory certifications apply to these parts?

A: All three parts (FN376-2-21, FN378-2-21, and 864-10/011) hold CSA, UL, and VDE approvals. FN378-2-21 and 864-10/011 are ROHS3 compliant, while FN376-2-21 is RoHS compliant.

Q: Can 864-10/011 be used in applications requiring 10A current capacity?

A: No. The 864-10/011 does not specify a 10A filter current rating. This part is suitable for applications with lower current requirements (4/6A appliance inlet rating). For 10A applications, FN376-2-21 is the original specification.
