Delta Electronics 03EB3 AC Power Connector - Equivalent & Substitute Parts

Part Overview

The Delta Electronics 03EB3 is an IEC 320-C14 power entry connector receptacle module designed for panel-mount applications. This filtered, dual-fused power inlet operates at 250VAC with a 3A current rating and includes integrated EMI/RFI filtering and on-off switching functionality. The connector features a voltage selector and accommodates a fuse (not included). With active product status and full compliance certifications (CSA, UL, VDE), this component is suitable for commercial equipment requiring filtered AC power distribution. Equivalent substitute parts may be required due to inventory availability, regional sourcing preferences, or packaging format requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Delta Electronics 03EB3 is determined by strict equivalence across the following critical parameters:

• Connector Style & Type: Must be IEC 320-C14 receptacle with male blades in module configuration
• Electrical Ratings: Current rating of 3A and voltage rating compatible with 250VAC operation
• Position Count: 3-position configuration required
• Filtering & Protection: EMI/RFI filtered, commercial-grade filtering required
• Switching & Fusing: On-off switch and twin-fused holder functionality mandatory
• Mounting Configuration: Panel mount with flange mounting required
• Termination Method: Quick connect termination required
• Regulatory Compliance: CSA, UL, and VDE certifications required

The Qualtek Electronics Corp. 864-03/001 meets all substitution criteria. Minor variations in panel cutout dimensions (28.96mm x 60.20mm versus 29.00mm x 60.20mm) fall within acceptable mechanical tolerance for panel-mount applications. The substitute part supports both 115VAC and 250VAC operation, providing broader voltage compatibility while maintaining full functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the Delta Electronics 03EB3 and Qualtek Electronics 864-03/001 maintain active product status with full regulatory compliance across CSA, UL, and VDE certifications. Selection between these parts should be based on:

• Inventory Availability: Delta 03EB3 has 1061 units in stock (bulk packaging); Qualtek 864-03/001 has 1207 units in stock (tray packaging)
• Packaging Format: Choose bulk packaging for high-volume applications; select tray packaging for controlled component distribution
• Voltage Flexibility: The Qualtek substitute supports dual-voltage operation (115/250VAC), providing operational flexibility in applications requiring voltage selection
• Panel Integration: The 0.04mm difference in horizontal cutout dimension (29.00mm versus 28.96mm) is negligible for standard panel-mount applications and does not affect functional compatibility

Both parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Qualtek 864-03/001 directly replace the Delta 03EB3 in existing designs?

A: Yes. Both connectors share identical IEC 320-C14 specifications, 3A/250VAC ratings, 3-position configuration, EMI/RFI filtering, on-off switching, twin-fused holder design, and panel-mount flange mounting. The 0.04mm panel cutout dimension variance is within standard mechanical tolerance for panel-mount applications.

Q: What is the significance of the voltage rating difference (250VAC versus 115/250VAC)?

A: The Delta 03EB3 is rated for 250VAC operation. The Qualtek 864-03/001 supports both 115VAC and 250VAC through its integrated voltage selector feature. In applications operating at 250VAC, both parts are functionally equivalent. The Qualtek part provides additional flexibility for dual-voltage equipment designs.

Q: Are there packaging considerations when selecting between these parts?

A: Yes. The Delta 03EB3 is supplied in bulk packaging, suitable for high-volume manufacturing runs. The Qualtek 864-03/001 is supplied in tray packaging, which provides better component organization and reduced handling damage during assembly operations. Select based on your production workflow and component handling requirements.

Q: Do both parts require fuses?

A: Both connectors accommodate fuses (not included) in their twin-fused holder design. Fuses must be sourced separately and installed according to the equipment's electrical protection requirements.

Q: Are both parts suitable for commercial equipment applications?

A: Yes. Both parts feature commercial-grade EMI/RFI filtering and hold active product status with full CSA, UL, and VDE certifications, making them suitable for commercial equipment requiring filtered AC power distribution.
