Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2805070 is determined by strict equivalence across the following critical parameters:

• Adapter Configuration: Jack-to-jack topology with BNC-to-BNC series conversion
• Electrical Impedance: 75-ohm characteristic impedance for RF signal integrity
• Gender Configuration: Female-to-female center contact arrangement
• Frequency Performance: Maximum operating frequency of 4 GHz
• Mechanical Interface: Bayonet lock fastening and DIN rail mounting compatibility
• Ingress Protection: IP20 rating for environmental sealing

The substitute part 2805083 maintains full equivalence across all specified parameters while offering the advantage of active product status and current manufacturing availability.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the 2805083 directly replace the 2805070 in existing installations?

A: Yes. Both adapters are electrically and mechanically equivalent across all specified parameters, including impedance, frequency response, connector gender configuration, and mounting interface.

Q: What is the primary difference between these two parts?

A: The 2805070 is obsolete, while the 2805083 is an active product with current manufacturing support. The 2805083 is supplied in bulk packaging, whereas the 2805070 packaging specification is not documented.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status, meeting the same regulatory standards.

Q: What connector types are compatible with these adapters?

A: Both adapters accept BNC jack female sockets on both ends, enabling connection between two BNC-terminated coaxial cables or components.

Q: Is the 75-ohm impedance critical for my application?

A: Yes. The 75-ohm impedance is specified for RF video and analog signal applications. Impedance mismatch will result in signal reflections and degraded performance. Verify your system design requires 75-ohm impedance before selection.

Q: What is the maximum frequency these adapters support?

A: Both adapters are rated for operation up to 4 GHz, suitable for standard RF and video signal transmission applications within this frequency range.
