Substitute Part Grouping Explanation

The Amphenol RF 082-4450 coaxial connector plug is substitutable with the 082-4474 based on electrical and mechanical parameter equivalence. Both parts maintain identical specifications across all critical substitution criteria:

Electrical Parameters: Both connectors operate at 50-ohm impedance with maximum frequency rating of 11 GHz, 1000 V voltage rating, and 0.15 dB insertion loss. Mating cycle rating of 500 cycles is consistent between both parts.

Mechanical Parameters: Both employ SC connector style with male pin configuration, crimp termination for contact and shield, threaded fastening, and free hanging (in-line) mounting type. Cable group compatibility is identical across both parts, supporting RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393 cable types.

Material Specifications: Both parts feature brass center contact and body materials with gold plating on the center contact and silver body finish. Dielectric material is polytetrafluoroethylene (PTFE) for both connectors.

Environmental and Compliance: Both parts maintain operating temperature range of -65°C to 165°C, ROHS3 compliance, REACH affected status, and moisture sensitivity level 1 (unlimited). ECCN and HTSUS classifications are identical.

The primary distinction between these parts is packaging configuration and inventory availability, with the 082-4474 offering 1148 pieces in stock compared to 689 pieces for the 082-4450.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 082-4450 and 082-4474 are active production parts with full ROHS3 compliance and REACH affected status. Selection between these equivalent parts should be based on inventory availability and procurement lead time requirements. The 082-4474 offers higher inventory availability with 1148 pieces in stock compared to 689 pieces for the 082-4450, providing improved supply chain flexibility for high-volume applications or extended production runs.

Both parts satisfy identical electrical performance requirements for 50-ohm RF coaxial applications operating up to 11 GHz with 1000 V voltage rating and 0.15 dB insertion loss. Mechanical compatibility is complete across all cable groups (RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, 393) and environmental operating conditions (-65°C to 165°C). Material composition, plating specifications, and termination methods are equivalent between both parts.

For applications requiring immediate availability or large quantity procurement, the 082-4474 is the preferred selection. For existing designs or applications with established part number specifications, the 082-4450 maintains full functional equivalence and interchangeability.
