R414703000 RF Attenuator Equivalent & Substitute Parts

Part Overview

The R414703000 is an RF attenuator manufactured by Radiall USA, Inc., designed for broadband attenuation applications across microwave frequencies. This N-Type in-line module provides 3dB attenuation with 2W power handling capability and 50-ohm impedance matching. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R414703000 are qualified based on the following critical parameters:

Mandatory Matching Parameters:

• Attenuation Value: 3dB (exact match required)
• Power Rating: 2W (minimum requirement)
• Impedance: 50 Ohms (system standard)
• Package Type: N-Type In-Line Module (mechanical compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Allowable Variation:

• Frequency Range: Substitute parts with extended frequency coverage (0 Hz ~ 18 GHz or higher) are acceptable, as they encompass the original 0 Hz ~ 12.4 GHz specification and provide backward compatibility.

The ATT-0219-03-NNN-02 meets all mandatory parameters and extends the frequency range capability, making it a valid parametric equivalent for applications requiring the R414703000 specifications.

Parameter Comparison

Engineering Selection Recommendations

R414703000 (Radiall USA, Inc.):

• Primary selection for applications requiring exact frequency range specification of 0 Hz ~ 12.4 GHz
• Active product status with established supply chain
• RoHS3 compliant for regulated environments
• EAR99 classification for export compliance

ATT-0219-03-NNN-02 (Cinch Connectivity Solutions Midwest Microwave):

• Suitable substitute when extended frequency coverage (0 Hz ~ 18 GHz) provides system margin
• Active product status with independent inventory availability
• RoHS3 compliant with REACH unaffected designation
• EAR99 classification for export compliance
• Identical electrical performance within the R414703000 operating band

Both parts satisfy identical attenuation, power, impedance, and mechanical interface requirements. Selection between them depends on frequency range requirements and supply availability.

Frequently Asked Questions (FAQ)

Q: Can ATT-0219-03-NNN-02 replace R414703000 in existing designs?

A: Yes. The ATT-0219-03-NNN-02 provides identical attenuation (3dB), power handling (2W), impedance (50 Ohms), and mechanical interface (N-Type in-line module). The extended frequency range (0 Hz ~ 18 GHz) encompasses the original specification (0 Hz ~ 12.4 GHz) and does not introduce incompatibility.

Q: Are there mechanical differences between these parts?

A: Both parts use N-Type in-line module packaging. No mechanical interface differences exist that would prevent direct substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are RoHS3 compliant and classified as EAR99 for export purposes. The ATT-0219-03-NNN-02 carries additional REACH unaffected designation.

Q: What is the significance of the extended frequency range in ATT-0219-03-NNN-02?

A: The extended range (18 GHz versus 12.4 GHz) provides additional operational margin and system flexibility. For applications limited to 12.4 GHz or below, this extension does not create performance issues and may benefit future system upgrades.

Q: Are there moisture sensitivity differences?

A: The R414703000 lists MSL as Not Applicable. The ATT-0219-03-NNN-02 specifies MSL 1 (Unlimited). Both designations indicate minimal moisture sensitivity concerns for standard handling and storage.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the application does not require frequency operation above 12.4 GHz exclusively. Both parts meet identical core specifications for attenuation, power, impedance, and mechanical interface.
