TE Connectivity Corcom Filters 6HJ4-4 AC Power Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity Corcom Filters 6HJ4-4 is a Power Entry Connector Receptacle module featuring IEC 320-C14 panel mount configuration with integrated EMI/RFI filtering for commercial and medical applications. This component combines a male blades receptacle, on-off switch, fuse holder, and voltage selector in a single snap-in panel mount assembly rated for 6A at 120/250VAC.

The 6HJ4-4 carries a Last Time Buy product status, indicating discontinued manufacturing. Identification of equivalent substitute parts is necessary to maintain design continuity and ensure procurement availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for AC power entry connector modules is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Electrical Compatibility:

• Connector style (IEC 320-C14)
• Connector type (Receptacle, Male Blades - Module)
• Current rating at appliance inlet (6A minimum)
• Filter type and current rating (Filtered EMI/RFI, 6A)
• Approval agencies (CSA, UL minimum)

Mechanical Compatibility:

• Mounting type (Panel Mount, Snap-In)
• Number of positions (3)
• Fuse holder accommodation

Functional Features:

• Voltage selector presence
• On-off switch capability
• Fuse holder drawer

The substitute part 6-6609947-2 meets these core criteria with the following considerations: voltage rating is reduced to 120VAC (single voltage versus dual voltage), termination connector size differs (0.187" versus 0.110"), and panel thickness accommodation range is expanded. These differences represent functional trade-offs rather than incompatibilities, as the substitute maintains the same connector style, current ratings, filtering specifications, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 6-6609947-2

The TE Connectivity Corcom Filters 6-6609947-2 is the manufacturer-recommended substitute for the discontinued 6HJ4-4. Both components are manufactured by TE Connectivity Corcom Filters and maintain identical IEC 320-C14 connector specifications, 6A current ratings, and EMI/RFI filtering for commercial and medical applications.

Compliance and Certification: The substitute part 6-6609947-2 carries Active product status with expanded regulatory approvals (CSA, UL, VDE) compared to the main part (CSA, UL). Both components are ROHS3 compliant and carry identical ECCN and HTSUS classifications.

Functional Differences: The substitute part operates at 120VAC single voltage rating versus the main part's 120/250VAC dual voltage capability. Applications requiring 250VAC operation cannot use this substitute. The substitute features a conversion clip in addition to the voltage selector, and accommodates a wider panel thickness range (0.031" ~ 0.114" versus 0.060" ~ 0.090").

Termination Consideration: The substitute employs 0.187" (4.7mm) quick connect termination versus the main part's 0.110" (2.8mm). This difference requires verification of mating connector compatibility in the target application.

Inventory Status: The substitute part 6-6609947-2 is available in higher inventory volume (1064 Pcs) compared to the main part's remaining stock (694 Pcs), supporting long-term procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can the 6-6609947-2 substitute directly replace the 6HJ4-4 in all applications?

A: Direct substitution is possible only in applications operating at 120VAC. The 6HJ4-4 supports both 120VAC and 250VAC operation through its voltage selector, while the 6-6609947-2 is rated for 120VAC only. Applications requiring 250VAC operation must retain the original 6HJ4-4 or identify alternative solutions.

Q: What is the significance of the different termination sizes (0.110" versus 0.187")?

A: The termination size determines compatibility with the mating quick connect receptacles on the internal wiring harness or PCB. The 0.110" termination on the 6HJ4-4 requires 0.110" quick connect sockets, while the 6-6609947-2 requires 0.187" quick connect sockets. Substitution requires verification that the target application's internal connectors match the substitute part's termination specification.

Q: Are both parts suitable for medical applications?

A: Yes. Both the 6HJ4-4 and 6-6609947-2 are specified as Filtered (EMI, RFI) - Commercial, Medical, indicating suitability for medical device applications. Both carry CSA and UL approvals required for medical equipment.

Q: What is the conversion clip feature on the 6-6609947-2?

A: The conversion clip is an additional mechanical feature on the substitute part. Its specific function is not detailed in the provided specifications. Verification of its relevance to the target application is necessary.

Q: Does the expanded panel thickness range of the 6-6609947-2 affect installation?

A: The 6-6609947-2 accommodates panel thicknesses from 0.031" to 0.114" (0.79mm to 2.90mm), compared to the 6HJ4-4's range of 0.060" to 0.090" (1.52mm to 2.29mm). The substitute provides greater flexibility for thinner and thicker panel installations. Verify that the target panel thickness falls within the substitute's range.

Q: Why does the 6HJ4-4 have Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued this product line. The 6-6609947-2, with Active status, represents the current production equivalent. New designs should transition to the substitute part to ensure long-term availability.

Q: Are there any differences in EMI/RFI filtering performance between the two parts?

A: Both parts are specified identically as Filtered (EMI, RFI) - Commercial, Medical with 6A current rating. No performance differences are indicated in the provided specifications.

Q: What regulatory approvals does each part carry?

A: The 6HJ4-4 carries CSA and UL approvals. The 6-6609947-2 carries CSA, UL, and VDE approvals, providing broader international regulatory coverage. Both are ROHS3 compliant.
