R413809000 RF Attenuator SMA 9dB 18GHz 2W Equivalent & Substitute Parts

Part Overview

The R413809000 is an RF attenuator manufactured by Radiall USA, Inc., designed for in-line SMA applications requiring 9dB attenuation across a frequency range of 0 Hz to 18 GHz. This component operates at 50 Ohms impedance with a 2W power rating and is housed in an SMA In-Line Module package. The product is currently Active and ROHS3 Compliant.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory requirements necessitate alternative sourcing from qualified manufacturers. Substitute parts must maintain identical electrical specifications including attenuation value, impedance, power rating, and package type to ensure functional compatibility in the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R413809000 are qualified based on the following critical parameters:

Mandatory Matching Parameters:

• Attenuation Value: 9dB
• Power Rating: 2W
• Impedance: 50 Ohms
• Package Type: SMA In-Line Module
• RoHS Compliance: ROHS3 Compliant

Frequency Range Consideration: The R413809000 operates across 0 Hz to 18 GHz. Substitute parts identified operate across 0 Hz to 6 GHz. Substitutes with reduced frequency range are applicable only when the target application operates within the 0 Hz to 6 GHz band. Applications requiring full 18 GHz coverage cannot use these substitutes.

The identified substitutes ATS-1M1F-09DB2W (Amphenol RF) and P1AT-SAMF-6G2W-9 (P1dB Inc) meet all mandatory electrical and mechanical parameters but operate within a narrower frequency specification.

Parameter Comparison

Engineering Selection Recommendations

R413809000 (Radiall USA, Inc.): Select this part when the application requires attenuation across the full 0 Hz to 18 GHz frequency range. The component is Active, ROHS3 Compliant, and classified under ECCN EAR99. Current inventory is 809 pieces.

ATS-1M1F-09DB2W (Amphenol RF): This substitute is applicable for applications operating within 0 Hz to 6 GHz. The part is Active, ROHS3 Compliant, REACH Affected, and classified under ECCN EAR99. Current inventory is 953 pieces. Moisture Sensitivity Level is rated at 1 (Unlimited).

P1AT-SAMF-6G2W-9 (P1dB Inc): This substitute is applicable for applications operating within 0 Hz to 6 GHz. The part is Active, ROHS3 Compliant, and REACH Unaffected. Current inventory is 812 pieces. Moisture Sensitivity Level is rated at 1 (Unlimited).

All three parts maintain identical electrical specifications for attenuation, power handling, impedance, and package configuration. Selection between substitutes depends on application frequency requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can ATS-1M1F-09DB2W or P1AT-SAMF-6G2W-9 be used as direct replacements for R413809000 in all applications?

A: No. The substitute parts operate across 0 Hz to 6 GHz, while the R413809000 operates across 0 Hz to 18 GHz. Substitutes are compatible only when the application operates within the 0 Hz to 6 GHz frequency band. Applications requiring operation above 6 GHz must use the R413809000.

Q: Are the electrical specifications identical between the main part and substitutes?

A: The attenuation value (9dB), power rating (2W), impedance (50 Ohms), and package type (SMA In-Line Module) are identical across all three parts. The primary difference is the maximum operating frequency.

Q: What is the significance of the SMA In-Line Module package?

A: The SMA In-Line Module package specifies the physical connector type and form factor. All three parts use identical SMA connectors, ensuring mechanical compatibility in the same circuit board layout and connector interface.

Q: Are all parts RoHS3 Compliant?

A: Yes. The R413809000, ATS-1M1F-09DB2W, and P1AT-SAMF-6G2W-9 are all ROHS3 Compliant, meeting environmental and hazardous substance restrictions.

Q: What is the difference between REACH Affected and REACH Unaffected status?

A: REACH Affected indicates the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Unaffected indicates the part does not contain such substances. Both statuses are compliant; the distinction reflects regulatory classification of component materials.

Q: Can frequency range be extended through circuit design modifications?

A: No. The frequency range specification is an inherent characteristic of the attenuator design and cannot be modified through external circuit modifications.
