FN281-4-06 Equivalent & Substitute Parts

Part Overview

The FN281-4-06 is an AC power entry connector module manufactured by Schaffner EMC Inc., designed as a receptacle with male blades conforming to the IEC 320-C14 standard. This filtered power entry module integrates EMI/RFI filtering for commercial applications and includes an on-off switch with integrated fuse holder. The component is actively produced and stocked at 1085 units, serving as a critical interface for AC power distribution in equipment requiring filtered power inlet protection.

Substitute parts are identified when equivalent functional performance can be achieved through components sharing the same connector style, filtering characteristics, and core electrical specifications while accommodating minor variations in termination, panel cutout geometry, or packaging format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN281-4-06 is determined by the following mandatory parameters:

• Connector Style: Must be IEC 320-C14 to ensure mechanical and electrical compatibility with mating plugs
• Connector Type: Must be Receptacle, Male Blades - Module configuration
• Filter Type: Must include EMI/RFI filtering for commercial applications
• Number of Positions: Must maintain 3-position configuration
• Switch Features: Must include on-off switching capability
• Fuse Accommodation: Must support fuse holder integration
• Mounting Type: Must be Panel Mount, Flange for identical installation geometry
• Product Status: Must be Active to ensure ongoing availability and support

The substitute part 5EFM1S meets these core functional requirements. Variations in termination connector size (0.110" vs. 0.250"), panel cutout dimensions, and current rating specifications (5A vs. 4A) represent acceptable engineering tolerances when the application circuit design accommodates the higher current rating.

Parameter Comparison

Engineering Selection Recommendations

Both FN281-4-06 and 5EFM1S are active products with current manufacturing support and full RoHS3 compliance. Selection between these components depends on specific application constraints:

FN281-4-06 is the primary choice when:

• Panel cutout dimensions of 29.00mm x 60.00mm are already established in equipment design
• Termination connections use 0.250" (6.3mm) quick-connect receptacles
• Compliance with CQC, ENEC certifications is required
• Current requirements do not exceed 4A

5EFM1S is suitable when:

• Panel cutout dimensions of 83.06mm x 29.21mm are compatible with equipment design
• Termination connections use 0.110" (2.8mm) quick-connect receptacles
• VDE certification is required in addition to CSA and UL
• Circuit design accommodates the 5A current rating
• Higher inventory availability (2300 units) supports supply chain requirements

Both components share identical IEC 320-C14 connector compatibility, EMI/RFI filtering architecture, on-off switching, and fuse holder integration. The substitution is valid when panel geometry and termination specifications can be accommodated in the target application.

Frequently Asked Questions (FAQ)

Q: Can 5EFM1S directly replace FN281-4-06 in existing equipment?

A: Direct mechanical replacement requires verification of panel cutout dimensions and termination connector compatibility. The FN281-4-06 uses a 29.00mm x 60.00mm rectangular cutout with 0.250" terminations, while 5EFM1S requires an 83.06mm x 29.21mm cutout with 0.110" terminations. Electrical substitution is valid when these physical parameters can be accommodated.

Q: Are there voltage or current limitations when using 5EFM1S as a substitute?

A: The 5EFM1S has a higher current rating (5A) compared to FN281-4-06 (4A). This represents a capability increase and does not restrict substitution. The 5EFM1S voltage rating of 120/250VAC is compatible with standard AC power distribution. Verify that the application circuit design operates within these electrical parameters.

Q: What are the packaging differences between these parts?

A: FN281-4-06 is supplied in Tray packaging, while 5EFM1S is supplied in Bulk packaging. This affects receiving, storage, and handling procedures but does not impact functional performance or electrical characteristics.

Q: Do both parts support the same fuse specifications?

A: Both components include fuse holder integration and accommodate fuses, though fuses are not included with either part. Fuse selection must be based on circuit protection requirements and the current rating of the specific application.

Q: Which certifications are critical for my application?

A: FN281-4-06 carries CQC, CSA, ENEC, and UL approvals. 5EFM1S carries CSA, UL, and VDE approvals. Verify that your application requirements align with the certification set of the selected component. Both are ROHS3 compliant and suitable for commercial filtered power entry applications.
