EAC333 Power Entry Connector - Equivalent & Substitute Parts

Part Overview

The EAC333 is an AC power entry connector receptacle manufactured by Switchcraft Inc., designed for IEC 320-C14 panel mount applications. This connector features male blades, solder termination, and a right-angle through-hole configuration. The product is currently active in production with 982 units in stock. Alternative equivalent parts may be required due to supply constraints, design revisions, or specific application requirements where panel cutout dimensions or mounting specifications differ.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EAC333 is determined by strict equivalence across the following critical parameters:

• Connector Style: IEC 320-C14 (mandatory match)
• Connector Type: Receptacle, Male Blades (mandatory match)
• Current Rating: 10A (mandatory match)
• Voltage Rating: 250VAC (mandatory match)
• Number of Positions: 3 (mandatory match)
• Mounting Type: Panel Mount, Flange; Through Hole, Right Angle (mandatory match)
• Termination: Solder (mandatory match)
• Filter Type: Unfiltered - Commercial (mandatory match)
• RoHS Compliance: ROHS3 Compliant (mandatory match)

The substitute part 703W-00/52 meets all mandatory electrical and mechanical parameters. Variations in panel cutout dimensions and panel thickness tolerance are acceptable within standard engineering practice for this connector category, provided the connector maintains functional compatibility with standard IEC 320-C14 plug interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both the EAC333 and 703W-00/52 are active production parts with ROHS3 compliance and valid regulatory certifications. The EAC333 carries approvals from DEMKO, NEMKO, SEMKO, SETI, and SEV. The 703W-00/52 carries approvals from CSA, UL, and VDE. Selection between these parts should be based on:

1. Regional regulatory requirements and applicable certification standards for the end application
2. Panel cutout dimensions and available panel thickness tolerance in the target assembly
3. Inventory availability and lead time requirements
4. Design documentation and approval history within the organization

Both connectors satisfy identical electrical specifications and mechanical mounting requirements for IEC 320-C14 applications.

Frequently Asked Questions (FAQ)

Q: Can the 703W-00/52 be used as a direct replacement for the EAC333 in existing designs?

A: The 703W-00/52 is electrically and mechanically equivalent to the EAC333 across all critical parameters. However, panel cutout dimensions differ slightly (EAC333: 30.56mm x 22.22mm versus 703W-00/52: 31.30mm x 23.30mm). Existing panel cutouts designed for the EAC333 will accommodate the 703W-00/52 without modification. Panel thickness tolerance also differs (EAC333: 0.130" versus 703W-00/52: 0.118"), which may affect flange seating depending on panel material and thickness specifications.

Q: Are there differences in regulatory approvals between these parts?

A: Yes. The EAC333 holds approvals from DEMKO, NEMKO, SEMKO, SETI, and SEV. The 703W-00/52 holds approvals from CSA, UL, and VDE. Both are valid certifications for commercial AC power connector applications. Selection should align with regional regulatory requirements for the target market.

Q: What is the significance of the terminating cover feature on the 703W-00/52?

A: The 703W-00/52 includes a terminating cover as a standard feature. The EAC333 does not list this feature. This is a design variation that does not affect electrical or mechanical compatibility but may influence assembly procedures and component appearance.

Q: Are both parts RoHS compliant?

A: Yes. Both the EAC333 and 703W-00/52 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.
