R413830150 Precision RF Attenuator SMA 30dB Module

Part Overview

The R413830150 is a precision RF attenuator manufactured by Radiall USA, Inc., designed for in-line attenuation applications across broadband frequency ranges. This active product operates at 30dB attenuation with 2W power handling capability across 0 Hz to 23 GHz, utilizing 50-ohm impedance in an SMA connector configuration. The component is housed in an SMA in-line module package and maintains ROHS3 compliance. Equivalent and substitute parts are identified when inventory constraints, lead time requirements, or application-specific frequency limitations necessitate alternative sourcing while maintaining core electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the R413830150 are classified based on strict adherence to the following core parameters: attenuation value (30dB), power rating (2W), impedance (50 ohms), and package configuration (SMA in-line module). All substitute parts maintain these critical electrical specifications and ROHS3 compliance status.

Frequency range variations exist among substitute options. The primary distinction between substitute parts is the maximum operating frequency:

Full-range substitutes (0 Hz ~ 18 GHz): Parts P1AT-SAMF-18G2W-30 and SA18E-30 operate across 18 GHz maximum frequency, providing coverage for applications not requiring the extended 23 GHz capability of the main part.
Limited-range substitutes (0 Hz ~ 6 GHz): Part SA6HA-30 operates across 6 GHz maximum frequency, suitable for applications with frequency requirements below 6 GHz.

All substitute parts are manufactured by established suppliers (P1dB Inc and Fairview Microwave) with active product status and current inventory availability.

Engineering Selection Recommendations

Selection of substitute parts must be based on application frequency requirements and compliance certifications. All listed substitute parts maintain ROHS3 compliance and active product status equivalent to the R413830150.

For applications requiring full 23 GHz coverage: The R413830150 remains the specified component, as no substitute part extends to 23 GHz maximum frequency.

For applications with frequency requirements up to 18 GHz: Parts P1AT-SAMF-18G2W-30 (P1dB Inc) and SA18E-30 (Fairview Microwave) are direct substitutes. Both maintain identical attenuation (30dB), power rating (2W), impedance (50 ohms), and package configuration. Selection between these two parts may be based on inventory availability, lead time, or supplier preference, as electrical specifications are equivalent.

For applications with frequency requirements up to 6 GHz: Part SA6HA-30 (Fairview Microwave) is a valid substitute. This part operates within a narrower frequency band but maintains all other critical electrical and mechanical parameters.

All substitute parts are manufactured by active suppliers with current inventory stock and maintain regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can P1AT-SAMF-18G2W-30 be used as a direct replacement for R413830150?

A: P1AT-SAMF-18G2W-30 is a parametric equivalent for applications operating at frequencies up to 18 GHz. Both parts share identical attenuation (30dB), power rating (2W), impedance (50 ohms), and SMA in-line module package configuration. Applications requiring operation above 18 GHz require the R413830150 or equivalent parts with extended frequency range.

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

A: Both parts are manufactured by Fairview Microwave and maintain identical attenuation (30dB), power rating (2W), impedance (50 ohms), and package type. The primary difference is frequency range: SA18E-30 operates to 18 GHz, while SA6HA-30 operates to 6 GHz. Selection depends on the maximum frequency requirement of the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (P1AT-SAMF-18G2W-30, SA18E-30, and SA6HA-30) maintain ROHS3 compliance equivalent to the R413830150.

Q: Can SA6HA-30 be used in an application designed for R413830150?

A: SA6HA-30 is suitable only for applications with maximum frequency requirements at or below 6 GHz. Applications requiring operation above 6 GHz require parts with extended frequency range such as P1AT-SAMF-18G2W-30, SA18E-30, or R413830150.

Q: What packaging is used for all listed parts?

A: All parts utilize SMA in-line module packaging, providing identical mechanical compatibility and connector configuration.

Q: Are there inventory differences between substitute parts?

A: Current inventory levels vary: R413830150 (1076 pcs), P1AT-SAMF-18G2W-30 (860 pcs), SA18E-30 (1053 pcs), and SA6HA-30 (1056 pcs). Inventory availability may influence sourcing decisions when lead time or stock requirements are critical factors.
