R414420150 Precision RF Attenuator 20dB BNC In-Line Module

Part Overview

The R414420150 is a precision RF attenuator manufactured by Radiall USA, Inc., designed for RF signal attenuation applications across the 0 Hz to 4 GHz frequency range. This active product operates at 50 Ohms impedance with a 2W power handling capacity in a BNC in-line module configuration. Alternative equivalent parts are necessary to support supply chain flexibility, inventory management, and procurement options from multiple qualified manufacturers while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R414420150 is determined by strict equivalence across five critical parameters: attenuation value (20dB), frequency range (0 Hz ~ 4 GHz), impedance (50 Ohms), power rating (2W), and package configuration (BNC in-line module). Only parts meeting all five criteria are classified as direct parametric equivalents. Parts that deviate from any of these specifications are not suitable substitutes and are excluded from the equivalent parts list.

The substitute parts CT3369A-20 and PE7437-20 meet all five critical parameters and are classified as full parametric equivalents. The part PE7438-20 shares four parameters but operates at 75 Ohms impedance instead of 50 Ohms, making it incompatible with the R414420150 specification and unsuitable for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

CT3369A-20 and PE7437-20 are direct parametric equivalents to the R414420150 and are suitable for interchangeable use in applications requiring 20dB attenuation at 50 Ohms impedance across the 0 Hz to 4 GHz frequency band. Both substitute parts are active products with confirmed inventory availability. CT3369A-20 carries ROHS3 compliance certification. PE7437-20 carries RoHS compliance certification. Both parts are REACH unaffected and classified under ECCN EAR99.

PE7438-20 operates at 75 Ohms impedance and is not suitable as a substitute for the R414420150, which requires 50 Ohms impedance operation. Use of PE7438-20 in a 50 Ohms system will result in impedance mismatch and signal degradation.

Frequently Asked Questions (FAQ)

Q: Can PE7438-20 be used as a substitute for R414420150?

A: No. PE7438-20 operates at 75 Ohms impedance while R414420150 requires 50 Ohms impedance. Impedance mismatch will cause signal reflections and system performance degradation. PE7438-20 is not a suitable substitute.

Q: What are the critical parameters that determine substitution eligibility?

A: Five parameters must match exactly: attenuation value (20dB), frequency range (0 Hz ~ 4 GHz), impedance (50 Ohms), power rating (2W), and package configuration (BNC in-line module). All five must be identical for direct substitution.

Q: Are CT3369A-20 and PE7437-20 electrically and mechanically interchangeable with R414420150?

A: Yes. Both parts meet all five critical parameters and are classified as direct parametric equivalents. Both are active products with confirmed inventory availability.

Q: What compliance certifications apply to the substitute parts?

A: CT3369A-20 is ROHS3 compliant and REACH unaffected. PE7437-20 is RoHS compliant and REACH unaffected. Both are classified under ECCN EAR99.

Q: Does the BNC in-line module package type affect substitution?

A: No. All equivalent parts use the same BNC in-line module configuration, ensuring mechanical compatibility and identical form factor.
