RF Attenuator 6820.17.A Equivalent & Substitute Parts

Part Overview

The Huber+Suhner 6820.17.A is an RF attenuator module designed for broadband signal attenuation applications. This in-line module provides fixed 20dB attenuation across a frequency range of 0 Hz to 12.4 GHz with 50 Ohm impedance and 1W power handling capability. The component is housed in an N-Type connector configuration for direct integration into RF transmission systems.

The part is currently in Active product status with 660 units available in inventory. Equivalent substitute parts may be required due to supply constraints, procurement lead times, or system integration preferences while maintaining identical electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6820.17.A is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Attenuation Value: 20dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 1W (exact match required)
• Package / Case: N-Type In-Line Module (exact match required)

Secondary Consideration:

• Frequency Range: The main part operates from 0 Hz to 12.4 GHz. Substitute parts with reduced frequency range (such as 0 Hz to 6 GHz) remain functionally equivalent for applications operating within the substitute's specified bandwidth but are not suitable for full-spectrum applications requiring the extended 12.4 GHz upper limit.

The Radiall USA R412720124 meets all primary substitution criteria with identical attenuation, impedance, power rating, and connector type. The frequency range difference represents a functional limitation for high-frequency applications above 6 GHz.

Engineering Selection Recommendations

Primary Selection: 6820.17.A (Huber+Suhner)

The 6820.17.A is the specified component and provides the full operational frequency range of 0 Hz to 12.4 GHz. This part is Active in product status with adequate inventory availability. REACH Unaffected status indicates no regulatory material restrictions.

Substitute Selection: R412720124 (Radiall USA)

The R412720124 is a parametric equivalent for applications operating within the 0 Hz to 6 GHz frequency band. This part is Active in product status with higher inventory availability (840 units). The substitute carries RoHS3 compliance certification and REACH Affected status, indicating full regulatory compliance for restricted substance management. Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) indicates no moisture-related handling restrictions.

Selection Constraint:

The R412720124 substitute is not suitable for applications requiring attenuation performance above 6 GHz. Applications utilizing frequencies between 6 GHz and 12.4 GHz require the primary 6820.17.A component to maintain specified attenuation characteristics across the full operational bandwidth.

Frequently Asked Questions (FAQ)

Q: Can the R412720124 be used as a direct replacement for the 6820.17.A in all applications?

A: The R412720124 is a direct replacement only for applications operating within the 0 Hz to 6 GHz frequency range. Applications requiring attenuation above 6 GHz must use the 6820.17.A to maintain performance specifications.

Q: Are the electrical specifications identical between these two parts?

A: The attenuation value (20dB), impedance (50 Ohms), power rating (1W), and connector type (N-Type In-Line Module) are identical. The frequency range differs, with the 6820.17.A supporting 12.4 GHz and the R412720124 supporting 6 GHz as upper limits.

Q: What is the physical difference between these components?

A: Both components use identical N-Type In-Line Module packaging. No physical modification or adapter is required for mechanical integration.

Q: Are there compliance or regulatory differences between these parts?

A: The R412720124 carries RoHS3 compliance and REACH Affected status, indicating full compliance with restricted substance directives. The 6820.17.A is REACH Unaffected. Both parts are Active in product status. System compliance requirements should determine part selection when regulatory status is a consideration.

Q: Which part should be selected for new designs?

A: For new designs, the primary 6820.17.A should be specified to ensure full frequency range capability. The R412720124 may be specified only when application requirements confirm operation within the 0 Hz to 6 GHz bandwidth and when RoHS3 compliance is a system requirement.
