Engineering Selection Recommendations
The 858-06/014 from Qualtek is a direct functional equivalent for the obsolete FN321-6-05. Both components share identical electrical specifications (6A current rating, IEC 320-C14 configuration, commercial-grade EMI/RFI filtering) and mechanical mounting requirements (panel mount flange, quick connect termination).
The 858-06/014 maintains active product status with current manufacturing availability (747 pcs in stock), whereas the FN321-6-05 is obsolete. Both parts carry CSA, UL, and VDE regulatory approvals, with the substitute meeting ROHS3 compliance standards. Panel cutout dimensions differ by 0.05mm and 0.10mm respectively, within standard manufacturing tolerances for this connector category and compatible with existing panel designs.
Frequently Asked Questions (FAQ)
Q: Can the 858-06/014 be used as a direct replacement for the FN321-6-05 in existing designs?
A: Yes. Both connectors share identical IEC 320-C14 specifications, 6A current ratings, and panel mount flange configurations. Panel cutout dimensions are within standard manufacturing tolerances (28.45mm x 21.60mm versus 28.50mm x 21.50mm).
Q: What are the key electrical parameters that define substitution compatibility?
A: Connector style (IEC 320-C14), connector type (receptacle with male blades), current rating (6A), and filter type (commercial-grade EMI/RFI) are the primary electrical criteria. Both parts meet these specifications identically.
Q: Are regulatory certifications equivalent between the two parts?
A: Both the FN321-6-05 and 858-06/014 carry CSA, UL, and VDE approvals. The 858-06/014 additionally meets ROHS3 compliance, exceeding the RoHS compliance level of the original part.
Q: What is the significance of the panel cutout dimension differences?
A: The 0.05mm to 0.10mm variation in panel cutout dimensions falls within standard manufacturing tolerances for IEC 320-C14 connectors and does not affect mechanical fit or functional compatibility in panel mount applications.
Q: Why is product status relevant to substitution selection?
A: The FN321-6-05 is classified as obsolete with no ongoing manufacturing, while the 858-06/014 maintains active status with current inventory availability, ensuring long-term supply chain reliability for new designs and system support.
