FN9263-3-06 Equivalent & Substitute Parts

Part Overview

The FN9263-3-06 is a power entry connector receptacle module manufactured by Schaffner EMC Inc., designed for IEC 320-C14 panel mount applications. This component functions as a filtered AC power inlet with integrated EMI/RFI filtering and on-off switch capability. The part carries a "Not For New Designs" status, making identification of active equivalent alternatives essential for ongoing production and new design implementations. The FN9264-4-06 serves as the primary substitute, offering improved current rating and active product status while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The FN9264-4-06 qualifies as a direct substitute for the FN9263-3-06 based on the following alignment of critical parameters:

• Identical connector style (IEC 320-C14) and type (Receptacle, Male Blades - Module)
• Matching number of positions (3)
• Identical filter type (Filtered EMI/RFI - Commercial) and switch configuration (On-Off)
• Identical mounting type (Panel Mount, Flange) and termination method (Quick Connect - 0.250")
• Matching material flammability rating (UL94 V-2) and ingress protection (IP40)
• Identical regulatory approvals (CQC, CSA, ENEC, UL) and RoHS compliance (ROHS3)

The primary difference is the increased current rating (4A versus 3A), which represents an enhancement rather than a limitation for substitution purposes. Panel cutout dimensions show minor variation (29.00mm x 33.00mm versus 29.20mm x 33.20mm), which falls within standard manufacturing tolerances for panel mount connectors.

Parameter Comparison

Engineering Selection Recommendations

The FN9264-4-06 is the appropriate substitute for the FN9263-3-06 in all applications where the original part was specified. The substitute maintains full electrical and mechanical compatibility while offering the advantage of active product status and increased current capacity. Both parts carry identical regulatory certifications (CQC, CSA, ENEC, UL) and RoHS3 compliance, ensuring no degradation in compliance posture. The higher current rating of the FN9264-4-06 (4A versus 3A) provides additional design margin without introducing any functional incompatibility. Panel cutout dimension variations are within acceptable manufacturing tolerances for panel mount connector applications.

Frequently Asked Questions (FAQ)

Q: Can the FN9264-4-06 be used as a direct replacement for the FN9263-3-06 in existing designs?

A: Yes. The FN9264-4-06 maintains identical connector style, type, position count, filtering characteristics, mounting configuration, and termination method. The increased current rating represents an enhancement that does not compromise compatibility.

Q: What is the significance of the current rating difference between these parts?

A: The FN9263-3-06 is rated for 3A while the FN9264-4-06 is rated for 4A. This difference reflects the filter component specifications. The higher rating of the substitute provides additional operational margin and is suitable for applications originally designed for the 3A part.

Q: Are there packaging differences between these parts?

A: Yes. The FN9263-3-06 is supplied in Tray packaging, while the FN9264-4-06 is supplied in Bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Do the panel cutout dimension differences affect installation?

A: The panel cutout dimensions differ slightly (29.20mm x 33.20mm versus 29.00mm x 33.00mm). These variations fall within standard manufacturing tolerances for panel mount connectors and do not prevent installation in existing panel cutouts designed for the original part.

Q: What is the significance of the "Not For New Designs" status on the FN9263-3-06?

A: This status indicates the part is obsolete for new design implementations. The FN9264-4-06, which carries "Active" status, should be specified for all new applications and ongoing production where the FN9263-3-06 was previously used.

Q: Are regulatory certifications maintained with the substitute part?

A: Yes. Both parts carry identical approvals from CQC, CSA, ENEC, and UL, and both are ROHS3 compliant. No compliance degradation occurs with substitution.
