03ME3DA Power Entry Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The 03ME3DA is an AC power entry connector receptacle manufactured by Delta Electronics, designed for IEC 320-C14 panel mount applications. This filtered power entry connector accommodates male pins with a 3A current rating at 115/250VAC, featuring EMI/RFI commercial-grade filtering. The component is actively produced and maintains full compliance with RoHS3 and international approval standards including CSA, UL, and VDE certification. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 03ME3DA is determined by the following critical parameters:

• Connector Style: Must be IEC 320-C14 to ensure mechanical and electrical compatibility with mating connectors
• Number of Positions: Must be 3 positions to match pin configuration
• Mounting Type: Must support Panel Mount with Flange and Through Hole, Right Angle orientation
• Termination Method: Must use Solder termination for PCB integration
• Filter Type: Must include EMI/RFI commercial-grade filtering at 3A rating
• Approval Certifications: Must maintain compliance with CSA, UL, or equivalent international standards
• RoHS Compliance: Must meet ROHS3 requirements

The FN9226-3-02 manufactured by Schaffner EMC Inc. qualifies as a substitute part based on alignment with these core parameters. Both components share identical connector style, position count, mounting configuration, termination method, and filtering specifications. Variations in panel cutout dimensions and material flammability rating reflect design differences between manufacturers but do not preclude functional substitution in applications where the mechanical envelope permits.

Parameter Comparison

Engineering Selection Recommendations

Both the 03ME3DA and FN9226-3-02 are active production components with full RoHS3 compliance and international regulatory approval. Selection between these parts should be based on the following engineering considerations:

03ME3DA (Delta Electronics): Suitable for applications requiring Delta Electronics supply chain integration or where the specified panel cutout dimensions (40.01mm x 22.86mm) align with existing mechanical designs. Maintains CSA, UL, and VDE certifications.

FN9226-3-02 (Schaffner EMC Inc.): Suitable for applications where the smaller panel cutout dimensions (34.40mm x 22.60mm) are compatible with mechanical constraints, or where Schaffner EMC supply chain relationships are established. Provides additional ingress protection specification (IP40) and material flammability rating (UL94 V-2). Maintains CSA, ENEC, SEMKO, and UL certifications.

Both parts satisfy the core electrical and filtering requirements for IEC 320-C14 power entry applications at 3A with commercial-grade EMI/RFI filtering. Panel cutout dimension compatibility must be verified during mechanical design phase to ensure proper fit and flange alignment.

Frequently Asked Questions (FAQ)

Q: Can the FN9226-3-02 directly replace the 03ME3DA in existing designs?

A: Functional electrical substitution is supported based on matching connector style, current rating, voltage rating, and filter specifications. However, mechanical compatibility must be verified. The FN9226-3-02 has different panel cutout dimensions (34.40mm x 22.60mm versus 40.01mm x 22.86mm), which may require panel modification or redesign depending on the application's mechanical envelope.

Q: What are the key differences between these two parts?

A: The primary differences are panel cutout dimensions, ingress protection rating (IP40 for FN9226-3-02), material flammability rating (UL94 V-2 for FN9226-3-02), and connector pin/blade configuration. Electrical performance, filtering capability, and current ratings are equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes, both the 03ME3DA and FN9226-3-02 are ROHS3 compliant and meet REACH requirements.

Q: Which certifications apply to each part?

A: The 03ME3DA holds CSA, UL, and VDE approvals. The FN9226-3-02 holds CSA, ENEC, SEMKO, and UL approvals. Both meet the primary international safety standards for power entry connectors.

Q: What is the difference between "Male Pins" and "Male Blades"?

A: Both designations refer to the contact configuration within the IEC 320-C14 receptacle. The functional compatibility with standard IEC 320-C14 plugs is maintained in both cases.

Q: Can I use these parts interchangeably in high-vibration or harsh environments?

A: The FN9226-3-02 specifies IP40 ingress protection, which may provide additional environmental protection compared to the 03ME3DA. Application-specific environmental requirements should be evaluated during component selection.
