Substitute Part Grouping Explanation

Substitute part identification for the 6820.17.B is based on strict equivalence of the following critical parameters:

Mandatory Matching Parameters:

• Attenuation Value: 20 dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 1 W (exact match required)
• Package Type: N-Type In-Line Module (exact match required)
• Product Status: Active (current production)

Frequency Range Consideration: The substitute part R412720124 operates across 0 Hz ~ 6 GHz, which represents a narrower frequency range than the main part specification of 0 Hz ~ 18 GHz. This substitute is applicable only for applications operating within the 0 Hz ~ 6 GHz band. For applications requiring full 0 Hz ~ 18 GHz coverage, the main part 6820.17.B must be specified.

The Radiall USA R412720124 meets all mandatory electrical and mechanical parameters within its specified frequency range and maintains active production status.

Engineering Selection Recommendations

Primary Part Selection (6820.17.B): Select the Huber+Suhner 6820.17.B for applications requiring full broadband coverage from 0 Hz to 18 GHz. This part is REACH Unaffected and maintains active production status. Use this specification when system bandwidth extends beyond 6 GHz.

Substitute Part Selection (R412720124): The Radiall USA R412720124 is applicable only for applications with maximum operating frequency of 6 GHz or lower. This substitute provides equivalent attenuation, power handling, impedance, and connector interface within its specified frequency range. The R412720124 is ROHS3 Compliant, REACH Affected, and classified as EAR99 for export control purposes. Moisture Sensitivity Level is rated 1 (Unlimited).

Compliance Considerations: Both parts maintain active production status. The main part carries REACH Unaffected status, while the substitute is REACH Affected. Selection should account for regulatory requirements specific to the end application and geographic market.

Frequently Asked Questions (FAQ)

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

A: No. The R412720124 substitute is limited to 0 Hz ~ 6 GHz operation, while the 6820.17.B operates to 18 GHz. Use R412720124 only when your application maximum frequency does not exceed 6 GHz. For broadband systems requiring frequencies above 6 GHz, the 6820.17.B is required.

Q: Are the electrical specifications identical between these parts?

A: Within the frequency range of 0 Hz ~ 6 GHz, both parts provide equivalent attenuation (20 dB), power handling (1 W), and impedance (50 Ohms). The R412720124 does not specify performance above 6 GHz.

Q: What is the difference in connector interface?

A: Both parts use N-Type in-line module connectors. The mechanical and electrical interface is identical.

Q: Are there compliance differences between the two parts?

A: Yes. The 6820.17.B is REACH Unaffected, while R412720124 is REACH Affected. The R412720124 is ROHS3 Compliant with EAR99 export classification. Verify compliance requirements for your specific application and market.

Q: Which part should I specify for a new design?

A: Specify 6820.17.B for designs requiring 0 Hz ~ 18 GHz coverage. Specify R412720124 only if your application is confirmed to operate within 0 Hz ~ 6 GHz and substitute sourcing is necessary.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: The 6820.17.B does not specify MSL in the provided data. The R412720124 is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
