RF Attenuator 6803.17.A Equivalent & Substitute Parts

Part Overview

The Huber+Suhner 6803.17.A is an RF attenuator module designed for inline applications requiring fixed 3dB attenuation across broadband frequencies. This component operates from DC to 12.4 GHz with 50-ohm impedance and 2-watt power handling capability in an N-type connector configuration. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuator modules is determined by matching the following critical parameters:

Attenuation Value: The substitute part must provide identical attenuation (3dB) to maintain signal level control in the circuit.

Impedance: The substitute part must operate at 50 ohms to ensure proper impedance matching and prevent signal reflections.

Power Rating: The substitute part must support minimum 2-watt power handling to accommodate thermal and electrical stress requirements.

Connector Type: The substitute part must use N-type connectors to ensure mechanical and electrical compatibility with existing interface hardware.

Frequency Coverage: The substitute part must cover the minimum required frequency range. Extended frequency coverage beyond the original specification does not disqualify a substitute part.

Compliance Standards: The substitute part must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements.

The ATT-0219-03-NNN-02 manufactured by Cinch Connectivity Solutions Midwest Microwave satisfies all substitution criteria through matching attenuation, impedance, power rating, connector type, and compliance certifications. The extended frequency range (0 Hz ~ 18 GHz) provides additional operational margin beyond the original 12.4 GHz specification.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part (6803.17.A) and the substitute part (ATT-0219-03-NNN-02) maintain Active product status, ensuring continued availability and manufacturer support. Both components satisfy ROHS3 compliance and REACH unaffected requirements, meeting current environmental and regulatory standards.

The ATT-0219-03-NNN-02 provides functional equivalence with extended frequency coverage to 18 GHz, which encompasses the original 12.4 GHz specification. This extended range does not introduce incompatibility and provides additional operational margin for future applications.

Selection between these parts should be based on supply chain availability, lead time requirements, and cost considerations. Both components deliver identical electrical performance within the specified 0 Hz to 12.4 GHz operating window.

Frequently Asked Questions (FAQ)

Q: Can the ATT-0219-03-NNN-02 be used as a direct replacement for the 6803.17.A?

A: Yes. Both parts provide 3dB attenuation, 50-ohm impedance, 2-watt power handling, and N-type connectors. The substitute part's extended frequency range (18 GHz versus 12.4 GHz) does not prevent direct substitution and provides additional operational capability.

Q: Does the extended frequency range of the ATT-0219-03-NNN-02 affect compatibility?

A: No. Extended frequency coverage is a superset of the original specification. The substitute part operates correctly across the entire 0 Hz to 12.4 GHz range required by the original application.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 6803.17.A and ATT-0219-03-NNN-02 are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements.

Q: What is the mechanical interface compatibility between these parts?

A: Both parts use N-type in-line module connectors, ensuring identical mechanical fit and electrical interface compatibility with existing RF systems.

Q: Are there any performance differences between these attenuators?

A: Both parts provide identical 3dB attenuation, 50-ohm impedance, and 2-watt power rating across the specified frequency range. Performance is equivalent within the 0 Hz to 12.4 GHz operating window.
