R413330150 Precision Attenuator SMA2.9 30D Equivalent & Substitute Parts

Part Overview

The R413330150 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 and 50-ohm impedance in an SMA connector configuration. The need for equivalent and substitute parts arises from inventory availability, lead time considerations, and application-specific frequency range requirements where the full 40 GHz capability of the primary part may exceed operational specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R413330150 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Attenuation Value: 30dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 2W (minimum requirement)
• Connector Type: SMA In-Line Module (exact match required)
• Product Status: Active (ensures availability and support)

Frequency Range Consideration: Substitute parts are grouped into two categories based on frequency range capability. Parts with frequency ranges equal to or exceeding the primary part's 0 Hz ~ 40 GHz specification provide full compatibility. Parts with reduced frequency ranges (0 Hz ~ 18 GHz or 0 Hz ~ 6 GHz) are suitable only for applications operating within their specified frequency limits.

All substitute parts listed maintain identical attenuation, power, impedance, and connector specifications as the primary part, ensuring electrical and mechanical interchangeability within their respective frequency operating windows.

Engineering Selection Recommendations

Full Frequency Range Compatibility: The R413330150 operates across 0 Hz ~ 40 GHz. No substitute parts in the provided list maintain this full frequency specification. Selection of any substitute part requires confirmation that the application operates within the substitute's frequency range limits.

Substitute Parts with 0 Hz ~ 18 GHz Range: The P1AT-SAMF-18G2W-30 (P1dB Inc) and SA18E-30 (Fairview Microwave) both provide 30dB attenuation, 2W power handling, and 50-ohm impedance across 0 Hz ~ 18 GHz. Both parts maintain Active product status. The P1AT-SAMF-18G2W-30 carries ROHS3 compliance and REACH Unaffected certification. The SA18E-30 carries ROHS3 compliance. These parts are suitable for applications not exceeding 18 GHz operational frequency.

Substitute Part with 0 Hz ~ 6 GHz Range: The SA6HA-30 (Fairview Microwave) provides identical attenuation, power, and impedance specifications within a 0 Hz ~ 6 GHz frequency window. This part carries ROHS3 compliance and maintains Active product status. Selection is appropriate only for applications operating within 6 GHz maximum frequency.

Compliance Considerations: All substitute parts maintain Active product status, ensuring continued manufacturer support and availability. Compliance certifications (ROHS3, REACH) are provided for parts where applicable and should be verified against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the P1AT-SAMF-18G2W-30 replace the R413330150 in all applications?

A: The P1AT-SAMF-18G2W-30 provides identical attenuation (30dB), power rating (2W), impedance (50 Ohms), and connector type (SMA In-Line Module). However, its frequency range is limited to 0 Hz ~ 18 GHz compared to the R413330150's 0 Hz ~ 40 GHz specification. Substitution is valid only for applications operating at or below 18 GHz.

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

A: Both parts are manufactured by Fairview Microwave and share identical attenuation (30dB), power (2W), impedance (50 Ohms), and connector specifications. 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 physically compatible with the R413330150?

A: Yes. All substitute parts use SMA In-Line Module connectors and maintain 50-ohm impedance, ensuring mechanical and electrical interface compatibility. Physical form factor compatibility should be confirmed against specific mounting or integration requirements.

Q: Do the substitute parts have the same power handling capability?

A: Yes. All substitute parts are rated for 2W power handling, matching the R413330150 specification. This ensures equivalent thermal and electrical performance within their respective frequency ranges.

Q: Which substitute part has the broadest frequency coverage?

A: The P1AT-SAMF-18G2W-30 and SA18E-30 both extend to 18 GHz, providing the broadest frequency coverage among the substitute options. The SA6HA-30 is limited to 6 GHz. Neither substitute matches the R413330150's full 40 GHz range.

Q: Are compliance certifications important for my application?

A: Compliance requirements depend on end-use application and regulatory jurisdiction. The P1AT-SAMF-18G2W-30 carries ROHS3 compliance and REACH Unaffected certification. The SA18E-30 and SA6HA-30 carry ROHS3 compliance. Verify compliance requirements against your specific application standards.

Q: Can I use the SA6HA-30 if my application operates at 12 GHz?

A: No. The SA6HA-30 is specified for 0 Hz ~ 6 GHz operation. Using it at 12 GHz exceeds its frequency specification and will not provide the specified 30dB attenuation performance. The P1AT-SAMF-18G2W-30 or SA18E-30 are appropriate for 12 GHz operation.
