Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 857-06/024 is determined by the following critical parameters:

• Connector Style & Type: Must be IEC 320-C14 receptacle with male blades
• Electrical Ratings: Current rating of 6A and voltage rating compatible with 115/250VAC operation
• Filter Specification: EMI/RFI filtered, commercial grade
• Termination Method: Quick connect termination
• Mounting Configuration: Panel mount with flange
• Regulatory Compliance: CSA, UL, and VDE approvals required

The Qualtek 858-06/011 meets all substitution criteria as an active product with identical electrical specifications, filter characteristics, and regulatory certifications. The primary difference is the panel cutout dimension (28.45mm x 21.60mm versus 30.48mm x 22.86mm) and mounting orientation (flange only versus flange with right angle).

Parameter Comparison

Engineering Selection Recommendations

The Qualtek 858-06/011 is the designated substitute for the obsolete 857-06/024. Both components maintain identical electrical performance specifications, filter ratings, and regulatory certifications (CSA, UL, VDE). The 858-06/011 holds active product status, ensuring continued availability and supply chain reliability.

Selection of the 858-06/011 requires verification of panel cutout compatibility. The substitute features a smaller rectangular cutout (28.45mm x 21.60mm) compared to the original part (30.48mm x 22.86mm). Additionally, the mounting orientation differs: the original includes right angle configuration while the substitute provides flange-only mounting. These mechanical differences necessitate panel modification or redesign consideration during implementation.

The voltage rating specification differs slightly: the original supports 115/250VAC while the substitute is rated for 250VAC. For applications requiring 115VAC operation, this distinction should be evaluated against actual system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 858-06/011 directly replace the 857-06/024 without modification?

A: Direct replacement requires panel cutout compatibility verification. The substitute has smaller cutout dimensions (28.45mm x 21.60mm versus 30.48mm x 22.86mm) and different mounting orientation (flange only versus flange with right angle). Panel modification may be necessary.

Q: Are the electrical specifications identical between these parts?

A: Both components are rated for 6A current and feature identical EMI/RFI filtered, commercial-grade protection. The voltage rating differs: the original supports 115/250VAC while the substitute is rated for 250VAC. Confirm your application voltage requirement before selection.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the 857-06/024 and 858-06/011 hold CSA, UL, and VDE approvals and are ROHS3 compliant.

Q: What is the primary advantage of selecting the 858-06/011?

A: The 858-06/011 maintains active product status, ensuring reliable supply chain availability and continued manufacturer support, unlike the obsolete 857-06/024.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified. The substitute is supplied in tray packaging.
