• Filter Type: Filtered (EMI, RFI) - Commercial
• Current Rating - Filter: 4A
• Mounting Type: Panel Mount, Flange
• Termination: Quick Connect
• Fuse Accommodation: Yes
• Panel Thickness Range: 0.031" ~ 0.126" (0.79mm ~ 3.20mm)
• Material Flammability Rating: UL94 V-2
• Ingress Protection: IP40
• Approval Agencies: CSA, UL, VDE

The substitute part FN378-4-22 meets all these criteria and belongs to the same FN 370 series, confirming functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The FN378-4-22 is the direct equivalent substitute for the obsolete FN376-4-22. Both components share identical electrical and mechanical specifications across all critical parameters. The FN378-4-22 offers the advantage of active product status, ensuring ongoing availability and supply chain support. The upgrade from RoHS Compliant to ROHS3 Compliant status on the substitute part reflects current regulatory alignment. Packaging is provided in tray format for the substitute part, supporting standard procurement and assembly workflows. No functional or compatibility compromises result from this substitution.

Frequently Asked Questions (FAQ)

Q: Can FN378-4-22 be used as a direct replacement for FN376-4-22?

A: Yes. Both parts are mechanically and electrically identical across all specified parameters, including connector style, current rating, mounting configuration, and approval certifications. The substitute part is the active equivalent.

Q: What is the difference between the two parts?

A: The primary differences are product status (FN376-4-22 is obsolete; FN378-4-22 is active) and RoHS compliance level (RoHS Compliant versus ROHS3 Compliant). Packaging differs (unspecified versus tray). All functional and mechanical parameters are equivalent.

Q: Are the panel mounting dimensions identical?

A: Yes. Both parts accommodate the same panel thickness range of 0.031" to 0.126" (0.79mm to 3.20mm) and use identical panel mount flange configurations.

Q: Do both parts support the same fuse accommodation?

A: Yes. Both parts accommodate fuses with a fuse holder drawer. The FN378-4-22 specifies twin fused capability, which does not affect compatibility with single-fuse applications.

Q: Are the termination methods compatible?

A: Yes. Both parts use quick connect termination, ensuring compatibility with existing wiring harnesses and assembly processes.

Q: What certifications apply to both parts?

A: Both parts carry CSA, UL, and VDE approvals with UL94 V-2 material flammability rating and IP40 ingress protection classification.
