Key Parameters

Substitute Part Grouping Explanation

Substitution of RF attenuators is determined by electrical and mechanical parameter alignment. The R413809115 and its identified substitutes share the following critical parameters:

Mandatory Matching Parameters:

• Attenuation Value: 9dB
• Power Rating: 2W
• Impedance: 50 Ohms
• Package / Case: SMA In-Line Module
• ECCN Classification: EAR99
• HTSUS Code: 8533.21.0090

Frequency Range Consideration: The R413809115 operates across 0 Hz to 4 GHz. Substitute parts identified operate across 0 Hz to 6 GHz, which encompasses the primary part's frequency range and provides extended operational capability. Parts operating at extended frequency ranges are electrically compatible with applications requiring the narrower 4 GHz specification.

All identified substitutes maintain active product status and are available in bulk packaging, ensuring supply chain compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The R413809115 remains the specified component when procurement requirements are limited to the 0 Hz to 4 GHz frequency range and when Radiall USA, Inc. sourcing is mandated by design or supply chain specifications.

Substitute Selection Criteria:

ATS-1M1F-09DB2W (Amphenol RF): This substitute is suitable for applications where extended frequency operation to 6 GHz is acceptable or beneficial. The part carries RoHS3 compliance and REACH Affected status, meeting modern environmental and regulatory requirements. Inventory availability is 953 units, providing supply security. ECCN and HTSUS classifications match the primary part.

P1AT-SAMF-6G2W-9 (P1dB Inc): This substitute is suitable for applications where extended frequency operation to 6 GHz is acceptable or beneficial. The part carries RoHS3 compliance and REACH Unaffected status. Inventory availability is 812 units. ECCN and HTSUS classifications are not specified for this part.

Both substitutes maintain identical attenuation, power rating, impedance, and package specifications, ensuring mechanical and electrical compatibility within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the ATS-1M1F-09DB2W be used as a direct replacement for the R413809115?

A: Yes. Both parts share identical attenuation (9dB), power rating (2W), impedance (50 Ohms), and SMA in-line module packaging. The ATS-1M1F-09DB2W operates across 0 Hz to 6 GHz, which encompasses the R413809115's 0 Hz to 4 GHz range. Direct mechanical and electrical substitution is supported.

Q: Can the P1AT-SAMF-6G2W-9 be used as a direct replacement for the R413809115?

A: Yes. Both parts share identical attenuation (9dB), power rating (2W), impedance (50 Ohms), and SMA in-line module packaging. The P1AT-SAMF-6G2W-9 operates across 0 Hz to 6 GHz, which encompasses the R413809115's 0 Hz to 4 GHz range. Direct mechanical and electrical substitution is supported.

Q: What is the significance of the extended frequency range in the substitute parts?

A: The substitute parts operate to 6 GHz, exceeding the primary part's 4 GHz specification. This extended range does not compromise compatibility with 4 GHz applications; it provides additional operational capability for systems requiring higher frequency performance without requiring component redesign.

Q: Are there compliance or regulatory differences between the primary part and substitutes?

A: The ATS-1M1F-09DB2W carries RoHS3 compliance and REACH Affected designation. The P1AT-SAMF-6G2W-9 carries RoHS3 compliance and REACH Unaffected designation. The primary part's compliance status is not specified in the provided data. Compliance requirements should be verified against system-level specifications before final part selection.

Q: What packaging formats are available for these parts?

A: All three parts are supplied in bulk packaging, consistent with production and assembly workflows. No alternative packaging formats are specified in the provided data.

Q: How do inventory levels compare across the three parts?

A: The R413809115 has 776 units in stock, the ATS-1M1F-09DB2W has 953 units, and the P1AT-SAMF-6G2W-9 has 812 units. All three parts maintain adequate inventory for procurement planning.

Q: Are there any frequency-dependent performance differences between these parts?

A: All three parts maintain 9dB attenuation across their respective frequency ranges. Within the 0 Hz to 4 GHz band common to all three parts, attenuation performance is equivalent. Performance differences, if any, occur only above 4 GHz in the substitute parts.
