Qualtek 857-03/047 AC Power Connector - Equivalent & Substitute Parts

Part Overview

The Qualtek 857-03/047 is an IEC 320-C14 power entry connector receptacle designed for panel-mount applications. This filtered power inlet accommodates male blade connectors with integrated EMI/RFI filtering for commercial applications. The component is actively manufactured and widely used in equipment requiring standards-compliant AC power distribution with electromagnetic interference suppression. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and regulatory certifications align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity Corcom Filters 6609015-4 qualifies as a substitute based on the following alignment of critical parameters:

Electrical Compatibility:

• Identical connector style (IEC 320-C14) and type (Receptacle, Male Blades)
• Matching current rating at appliance inlet (3A)
• Compatible voltage rating (120/250VAC vs. 115/250VAC)
• Identical filter type and current rating (Filtered EMI/RFI, 3A)
• Same number of positions (3)

Mechanical Compatibility:

• Panel mount configuration with flange and right-angle orientation
• Panel cutout dimensions within tolerance (30.48mm x 22.86mm vs. 30.50mm x 22.86mm)

Regulatory Compliance:

• Identical approval agencies (CSA, UL, VDE)
• ROHS3 compliant
• REACH unaffected status

Termination Difference: The substitute uses Quick Connect 0.250" (6.3mm) termination instead of solder eyelet. This represents a functional difference requiring board-level design consideration.

Parameter Comparison

Engineering Selection Recommendations

Both the Qualtek 857-03/047 and TE Connectivity 6609015-4 maintain active product status with identical regulatory certifications (CSA, UL, VDE) and ROHS3 compliance. Selection between these components depends on termination method compatibility:

Qualtek 857-03/047 is appropriate for designs requiring solder eyelet termination for direct PCB integration through through-hole soldering.

TE Connectivity 6609015-4 is appropriate for designs utilizing quick-connect 0.250" (6.3mm) termination, which accommodates spade lug connections and reduces soldering requirements.

Both components satisfy identical electrical specifications (3A at 115/250VAC) and filtering requirements (EMI/RFI commercial grade). Panel cutout dimensions are functionally equivalent within standard manufacturing tolerances.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6609015-4 directly replace the Qualtek 857-03/047 without design modification?

A: Direct replacement requires termination compatibility. The Qualtek uses solder eyelet termination while the TE Connectivity uses quick-connect 0.250" spade lug termination. If your design accommodates quick-connect termination, substitution is feasible. If your design requires solder eyelet termination, board-level modification is necessary.

Q: Are the panel cutout dimensions identical?

A: Panel cutout dimensions are functionally equivalent. Qualtek specifies 30.50mm x 22.86mm while TE Connectivity specifies 30.48mm x 22.86mm. The 0.02mm difference in one dimension falls within standard manufacturing tolerances for rectangular panel cutouts and does not affect mechanical fit.

Q: Do both components provide equivalent EMI/RFI filtering?

A: Both components are specified as Filtered (EMI, RFI) - Commercial grade with identical 3A current ratings. Filtering performance is equivalent for commercial applications.

Q: Are regulatory certifications identical?

A: Both components carry CSA, UL, and VDE approvals with ROHS3 compliance and REACH unaffected status. Regulatory compliance is equivalent.

Q: What is the voltage rating difference between 115/250VAC and 120/250VAC?

A: Both ratings accommodate standard North American and international AC power distribution. The 5V difference in the lower voltage specification reflects regional supply variations and does not affect component functionality in either region.
