Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R414719161 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Impedance: 50 Ohms (mandatory match)
• Package/Case: N-Type In-Line Module (mandatory match)
• Power Rating: 2W (mandatory match)
• Frequency Range: Must encompass or equal 0 Hz ~ 18 GHz operational band
• Product Status: Active (current production availability)

Attenuation Value Consideration: The R414719161 specifies 19dB attenuation. Substitute parts with different attenuation values (such as 20dB) are listed as parametric equivalents when all other electrical and mechanical parameters align. Selection between 19dB and 20dB variants depends on circuit-specific attenuation requirements.

Parameter Comparison

Engineering Selection Recommendations

R414720000 (Radiall USA, Inc.): This substitute maintains identical power rating, impedance, and package configuration. The attenuation value differs at 20dB versus 19dB. The frequency range limitation to 12.4 GHz restricts operation below the full 18 GHz capability of the main part. Selection of this substitute is appropriate only when circuit requirements accommodate the reduced frequency range and 20dB attenuation specification. RoHS3 compliance is documented.

ATT-0219-20-NNN-02 (Cinch Connectivity Solutions Midwest Microwave): This substitute provides full frequency range equivalence (0 Hz ~ 18 GHz) with matching power rating, impedance, and N-Type in-line package. The attenuation value is 20dB. Both RoHS3 compliance and REACH unaffected status are documented. This part maintains complete electrical and mechanical compatibility across the specified operational bandwidth.

Compliance and Availability: All three parts maintain Active product status with current production availability. All parts carry EAR99 export classification. The substitute parts provide documented RoHS3 compliance, supporting environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can R414720000 replace R414719161 in all applications? A: R414720000 maintains identical power rating, impedance, and package type. However, the frequency range is limited to 12.4 GHz compared to the 18 GHz specification of R414719161. Additionally, attenuation differs at 20dB versus 19dB. Substitution is valid only when circuit design accommodates both the reduced frequency range and the 1dB attenuation difference.

Q: What is the primary difference between the two substitute parts? A: Both ATT-0219-20-NNN-02 and R414720000 provide 20dB attenuation with 2W power handling and 50 Ohm impedance in N-Type in-line packages. The critical distinction is frequency range: ATT-0219-20-NNN-02 operates across the full 0 Hz ~ 18 GHz band, while R414720000 is limited to 0 Hz ~ 12.4 GHz. Manufacturer sourcing also differs.

Q: Does the 1dB attenuation difference between 19dB and 20dB affect substitution? A: Attenuation value is a primary electrical parameter. The 1dB difference between 19dB and 20dB variants must be evaluated against specific circuit requirements. Both values are listed as parametric equivalents based on matching impedance, power rating, package type, and product status. Circuit-level validation is required to confirm acceptable performance.

Q: Are all substitute parts RoHS compliant? A: R414720000 and ATT-0219-20-NNN-02 are both documented as ROHS3 compliant. RoHS status for the main part R414719161 is not specified in the provided data.

Q: Can these parts be used interchangeably in the same connector interface? A: All three parts utilize N-Type in-line module packaging, ensuring mechanical compatibility at the connector interface. Electrical substitution depends on matching the attenuation value and frequency range requirements of the specific application circuit.

Q: What is the inventory status for these parts? A: R414719161 has 1107 pieces in stock. R414720000 has 956 pieces in stock. ATT-0219-20-NNN-02 has 839 pieces in stock. All parts are listed as new original stock.
