Parameter Comparison

Engineering Selection Recommendations

Substitution Basis: The Cinch Connectivity Solutions VB1094-75 is electrically and mechanically compatible with the Winchester Interconnect 326A515 for standard RF coaxial connector applications. Both components maintain identical voltage ratings, mating cycle specifications, insertion loss characteristics, and RoHS compliance status.

Material Considerations: The substitute part uses zinc body material with brass center contact, compared to the main part's brass body with phosphor bronze center contact. Both configurations are finished with nickel and gold plating respectively, providing equivalent corrosion resistance and electrical performance in standard operating environments.

Temperature Range: The substitute part operates across a wider temperature range (-55°C to 85°C) compared to the main part (-40°C to 85°C), providing additional thermal margin for extended environmental applications.

Impedance Specification: The substitute part is specified at 75 Ohms impedance with a maximum frequency rating of 1 GHz. The main part does not provide impedance or frequency specifications. For applications requiring specific impedance matching or frequency performance, impedance specification should be confirmed against application requirements.

Regulatory Compliance: Both components are RoHS Compliant and carry identical Moisture Sensitivity Level ratings, meeting standard regulatory requirements for electronic component procurement.
