Key Parameters

Substitute Part Grouping Explanation

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

Primary Electrical Specifications:

• Attenuation Value: 20dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 1W (exact match required)

Mechanical Compatibility:

• Package Type: BNC In-Line Module (exact match required)

Operational Range:

• Frequency Range: The substitute part must support the frequency range of the primary application. The 6820.01.A operates 0 Hz ~ 4 GHz; substitute parts operating within this range or at higher maximum frequencies are functionally compatible.

The identified substitute R412420124 matches all primary electrical specifications and mechanical form factor. The substitute operates at 0 Hz ~ 3 GHz, which represents a narrower frequency range than the primary part. Selection between these parts depends on the specific frequency requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (6820.01.A): Select the Huber+Suhner 6820.01.A when applications require operation across the full 0 Hz to 4 GHz frequency range. This part carries REACH Unaffected status, simplifying regulatory compliance in certain jurisdictions.

Substitute Part Selection (R412420124): The Radiall USA R412420124 is electrically and mechanically compatible for applications operating within the 0 Hz to 3 GHz frequency range. This substitute provides higher inventory availability (1160 units) and carries ROHS3 Compliance certification. The R412420124 is subject to REACH regulations, which may require additional compliance documentation depending on end-use geography and application classification.

Frequency Range Consideration: Applications requiring attenuation above 3 GHz must use the primary part 6820.01.A. Applications limited to 3 GHz and below may use either part based on inventory, compliance, and supply requirements.

Frequently Asked Questions (FAQ)

Q: Can R412420124 be used in place of 6820.01.A in all applications?

A: The R412420124 is compatible only for applications operating at frequencies up to 3 GHz. The primary part 6820.01.A supports frequencies to 4 GHz. Verify your application's maximum operating frequency before substitution.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts provide 20dB attenuation, 1W power handling, and 50 Ohm impedance. The mechanical form factor (BNC In-Line Module) is identical.

Q: What is the difference in REACH and RoHS status?

A: The 6820.01.A carries REACH Unaffected status, while the R412420124 is REACH Affected and ROHS3 Compliant. These designations affect regulatory compliance requirements based on end-use location and application type. Consult regional compliance requirements for your specific use case.

Q: Which part should I select for new designs?

A: For new designs, select based on the maximum frequency requirement. If 4 GHz operation is needed, use 6820.01.A. If 3 GHz is sufficient, either part is acceptable; consider inventory availability and compliance requirements in your region.

Q: Are there any performance differences between these attenuators?

A: Both parts meet the specified 20dB attenuation, 1W power, and 50 Ohm impedance parameters. Performance differences, if any, would be within manufacturer tolerances not specified in the provided data.
