R413809121 RF Attenuator SMA 9dB 26.5GHz 2W Equivalent & Substitute Parts

Part Overview

The R413809121 is an RF attenuator manufactured by Radiall USA, Inc., designed for high-frequency signal attenuation applications. This SMA in-line module provides 9dB attenuation across a frequency range of 0 Hz to 26.5 GHz with 50-ohm impedance and 2-watt power handling capability. The component is classified as Active product status and maintains ROHS3 compliance. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining electrical and mechanical compatibility within specified operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by matching the following critical parameters: attenuation value (9dB), impedance (50 ohms), power handling (2W), package configuration (SMA in-line module), and connector type. The frequency range represents an operational boundary; substitute parts with lower maximum frequency ratings (0 Hz ~ 6 GHz) are suitable for applications operating within that reduced bandwidth. All identified substitutes maintain identical attenuation, impedance, power, and package specifications. RoHS3 compliance is maintained across all substitute options. Substitution is valid when the application frequency requirements do not exceed the substitute part's maximum frequency specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment and supply chain continuity. The R413809121 provides extended frequency coverage to 26.5 GHz, suitable for millimeter-wave and high-frequency applications. The ATS-1M1F-09DB2W and P1AT-SAMF-6G2W-9 are frequency-limited to 6 GHz but remain valid substitutes for applications operating within this bandwidth. Selection between substitute parts should be based on application frequency requirements: use the R413809121 or equivalent 26.5 GHz-rated attenuator for broadband or high-frequency systems; use ATS-1M1F-09DB2W or P1AT-SAMF-6G2W-9 for applications with maximum operating frequencies at or below 6 GHz. All parts share identical electrical characteristics (9dB attenuation, 50-ohm impedance, 2W power handling) and mechanical form factor (SMA in-line module), ensuring direct mechanical and electrical interchangeability within their respective frequency domains.

Frequently Asked Questions (FAQ)

Q: Can the ATS-1M1F-09DB2W or P1AT-SAMF-6G2W-9 be used as direct replacements for the R413809121 in all applications?

A: Direct substitution is valid only for applications with maximum operating frequencies at or below 6 GHz. The R413809121 supports frequencies to 26.5 GHz; the substitute parts do not. Applications requiring operation above 6 GHz must use the R413809121 or an equivalent part rated for the required frequency range.

Q: Are the mechanical interfaces identical between all three parts?

A: Yes. All three parts use SMA in-line module packaging, ensuring identical mechanical fit and connector compatibility.

Q: Do all parts meet the same compliance standards?

A: All three parts are ROHS3 compliant and maintain Active product status. The ATS-1M1F-09DB2W carries additional REACH Affected designation; the P1AT-SAMF-6G2W-9 is REACH Unaffected.

Q: What is the primary difference between these parts?

A: The primary difference is frequency range. The R413809121 operates to 26.5 GHz, while ATS-1M1F-09DB2W and P1AT-SAMF-6G2W-9 operate to 6 GHz. Attenuation value, impedance, power handling, and package type are identical across all three parts.

Q: Can these parts be used interchangeably in RF test equipment?

A: Interchangeability depends on the equipment's operating frequency. Equipment operating at or below 6 GHz can use any of the three parts. Equipment requiring operation above 6 GHz must use the R413809121 or an equivalent part with matching frequency specifications.

Q: What moisture sensitivity levels apply to these parts?

A: The R413809121 has moisture sensitivity not applicable. The ATS-1M1F-09DB2W and P1AT-SAMF-6G2W-9 are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
