Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN9263S-3-06 is determined by strict alignment of the following parameters:

• Connector style and type (IEC 320-C14, Receptacle, Male Blades - Module)
• Number of positions (3)
• Filter type and EMI/RFI protection classification (Filtered - Commercial)
• Mounting configuration (Panel Mount, Snap-In)
• Termination method (Quick Connect - 0.250")
• Regulatory compliance (UL94 V-2, IP40, CQC, CSA, ENEC, UL)
• RoHS compliance status (ROHS3 Compliant)

The FN9264S-4-06 qualifies as a substitute part because it maintains identical specifications across all critical parameters listed above. The primary difference is the current rating of the filter (4A versus 3A), which represents a higher capacity rating suitable for applications requiring increased current handling.

Parameter Comparison

Engineering Selection Recommendations

The FN9264S-4-06 is the qualified substitute for the FN9263S-3-06. Both parts maintain identical connector architecture, filtering specifications, and regulatory certifications (CQC, CSA, ENEC, UL). The FN9264S-4-06 carries an "Active" product status, ensuring ongoing manufacturer support and availability, whereas the FN9263S-3-06 is designated "Not For New Designs."

Selection between these parts depends on application current requirements. The FN9263S-3-06 is rated for 3A filter current, while the FN9264S-4-06 is rated for 4A. Panel cutout dimensions and panel thickness tolerances differ slightly between the two models; verify mechanical compatibility with existing panel installations before substitution.

Frequently Asked Questions (FAQ)

Q: Can the FN9264S-4-06 directly replace the FN9263S-3-06 in existing installations?

A: Functional compatibility is confirmed across all electrical and filtering specifications. Mechanical compatibility requires verification of panel cutout dimensions (29.00mm x 32.60mm for FN9263S-3-06 versus 29.50mm x 33.00mm for FN9264S-4-06) and panel thickness tolerance ranges (0.60mm–1.50mm versus 1.00mm–2.50mm).

Q: What is the significance of the current rating difference (3A versus 4A)?

A: The current rating indicates the maximum current the integrated filter can safely handle. The FN9264S-4-06 provides higher current capacity. Selection should align with the actual circuit current requirements of the application.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the FN9263S-3-06 and FN9264S-4-06 carry identical approval certifications (CQC, CSA, ENEC, UL) and material flammability ratings (UL94 V-2), with IP40 ingress protection and ROHS3 compliance.

Q: Why is the FN9263S-3-06 marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's active product portfolio. The FN9264S-4-06 represents the current generation equivalent and is recommended for new applications.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in tray packaging. Inventory availability should be confirmed with the supplier, as stock levels may vary.
