PE782003 AC Power Connector - Equivalent & Substitute Parts

Part Overview

The PE782003 is an IEC 320-C14 power entry connector receptacle manufactured by Curtis Industries, designed for AC power applications requiring filtered EMI/RFI suppression. This panel-mount module features male blades, a twin-fused fuse holder, and voltage selector functionality. The component is actively produced and maintains full compliance with international standards including CE, CSA, TUV, and UL certifications. Substitute parts are identified when equivalent electrical and mechanical specifications align with the primary connector style, filtering characteristics, and mounting requirements.

Key Parameters

Substitute Part Grouping Explanation

The FN378-4-21 manufactured by Schaffner EMC Inc. qualifies as a substitute based on the following alignment of critical parameters:

Both components share the IEC 320-C14 connector style with receptacle, male blades configuration and 3-position design. Both feature commercial-grade EMI/RFI filtering, twin-fused fuse holder drawers, and panel-mount flange installation. Both accommodate fuses and include voltage selector functionality. Both maintain ROHS3 compliance and REACH unaffected status with identical HTSUS classification (8536.30.8000).

The FN378-4-21 supports a higher filter current rating of 4A compared to the PE782003's 3A rating, making it suitable for applications within the PE782003's 3A specification. The FN378-4-21 offers variable panel thickness accommodation (0.79mm to 3.20mm) and front or rear side mount flexibility, providing broader installation compatibility. Both components hold active product status and maintain international certifications (CSA, UL, VDE for FN378-4-21; CE, CSA, TUV, UL for PE782003).

Parameter Comparison

Engineering Selection Recommendations

Both PE782003 and FN378-4-21 maintain active product status with full regulatory compliance. The PE782003 holds certifications from CE, CSA, TUV, and UL. The FN378-4-21 holds certifications from CSA, UL, and VDE. Selection between these components depends on specific application requirements and regional compliance mandates. The FN378-4-21's higher filter current rating (4A) and variable panel thickness accommodation provide expanded operational flexibility for installations with dimensional constraints or higher current margin requirements. Both components satisfy ROHS3 and REACH compliance requirements for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can FN378-4-21 directly replace PE782003 in existing designs?

A: Both components share identical IEC 320-C14 connector style, receptacle configuration, 3-position design, and twin-fused fuse holder functionality. The FN378-4-21's 4A filter rating exceeds the PE782003's 3A specification, maintaining compatibility for applications rated at 3A. Panel cutout dimensions differ (PE782003: 28.50mm x 55.90mm fixed; FN378-4-21: variable size), requiring verification of mechanical fit in existing panel installations.

Q: What are the key electrical compatibility factors?

A: Both components feature commercial-grade EMI/RFI filtering and identical connector style. The FN378-4-21's higher filter current rating (4A versus 3A) does not create incompatibility for 3A-rated applications. Voltage ratings and position counts are equivalent across both designs.

Q: Are there packaging differences between these components?

A: PE782003 is supplied in bulk packaging with 856 pieces in stock. FN378-4-21 is supplied in tray packaging with 980 pieces in stock. Packaging format does not affect electrical or mechanical performance.

Q: Which certifications apply to each component?

A: PE782003 holds CE, CSA, TUV, and UL approvals. FN378-4-21 holds CSA, UL, and VDE approvals. Both maintain ROHS3 compliance and REACH unaffected status. Regional application requirements determine which certification set is necessary.

Q: What mounting flexibility does FN378-4-21 offer?

A: FN378-4-21 supports front or rear side mount configuration with variable panel thickness accommodation (0.79mm to 3.20mm). PE782003 specifies panel mount flange only. This additional flexibility in FN378-4-21 may accommodate a broader range of panel installations.
