R413830121 RF Attenuator SMA 30dB 26.5GHz Equivalent & Substitute Parts

Part Overview

The R413830121 is an RF attenuator manufactured by Radiall USA, Inc., designed for inline attenuation applications across a broad frequency range. This SMA-connectorized module provides 30dB attenuation with 2W power handling capability and 50-ohm impedance. The part is currently active in production with 752 units in stock. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific frequency limitations necessitate alternative component selection while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R413830121 are classified based on alignment with the following critical parameters: attenuation value (30dB), impedance (50 ohms), power handling (2W), and connector type (SMA in-line module). Substitution eligibility is determined by exact matching of these core electrical specifications. Frequency range variations are noted as a limiting factor for application compatibility. Parts with identical attenuation, impedance, power rating, and package configuration are considered parametric equivalents, with frequency range serving as a constraint on their deployment scope rather than a disqualifier for substitution status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and are available in production quantities. The P1AT-SAMF-18G2W-30 and SA18E-30 are functionally equivalent to the R413830121 across all core electrical parameters (30dB attenuation, 2W power, 50-ohm impedance, SMA in-line configuration) with the constraint that their frequency range extends to 18 GHz rather than 26.5 GHz. These parts are suitable for applications operating within the 0 Hz to 18 GHz band. The SA6HA-30 maintains identical electrical specifications but operates within a reduced frequency range of 0 Hz to 6 GHz, limiting its application scope to lower-frequency systems. Selection should be based on the required operating frequency of the target application. The P1AT-SAMF-18G2W-30 carries ROHS3 compliance and REACH unaffected status. The SA18E-30 and SA6HA-30 carry ROHS3 compliance. All substitute parts are packaged in bulk format consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can the P1AT-SAMF-18G2W-30 be used as a direct replacement for the R413830121?

A: The P1AT-SAMF-18G2W-30 is a parametric equivalent with identical attenuation (30dB), power rating (2W), impedance (50 ohms), and SMA in-line package configuration. It is suitable for applications operating within its 0 Hz to 18 GHz frequency range. Applications requiring operation above 18 GHz require the R413830121 or equivalent parts with extended frequency capability.

Q: What is the primary difference between the SA18E-30 and SA6HA-30?

A: Both parts are manufactured by Fairview Microwave and share identical electrical specifications (30dB attenuation, 2W power, 50-ohm impedance, SMA in-line module). The SA18E-30 operates across 0 Hz to 18 GHz, while the SA6HA-30 operates across 0 Hz to 6 GHz. Selection depends on the maximum frequency requirement of the application.

Q: Are all substitute parts available in the same packaging format as the R413830121?

A: Yes. The R413830121 and all listed substitute parts (P1AT-SAMF-18G2W-30, SA18E-30, SA6HA-30) are packaged as SMA in-line modules in bulk format, ensuring mechanical and connector compatibility.

Q: What compliance certifications apply to the substitute parts?

A: The P1AT-SAMF-18G2W-30 is ROHS3 compliant and REACH unaffected. The SA18E-30 and SA6HA-30 are ROHS3 compliant. Compliance requirements for specific applications should be verified against these certifications.

Q: How does frequency range affect substitution eligibility?

A: Frequency range is a limiting parameter for application compatibility but does not disqualify a part from substitution status if all other core electrical parameters match. A substitute part with a lower maximum frequency rating can be used only in applications operating within its specified frequency band. Applications requiring the full 26.5 GHz capability of the R413830121 cannot use the 18 GHz or 6 GHz variants.
