Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R413800121 are qualified based on the following critical parameters:

Mandatory Matching Parameters:

• Attenuation Value: 0 dB
• Power Rating: 2W
• Impedance: 50 Ohms
• Package Type: SMA In-Line Module
• RoHS Compliance: ROHS3 Compliant
• Product Status: Active

Frequency Range Consideration: The R413800121 operates to 26.5 GHz. Substitute parts R411800121 and SF0929-6200-00 operate to 18 GHz maximum frequency. These substitutes are applicable in applications where the operating frequency does not exceed 18 GHz, representing a frequency-limited substitution scenario.

Parameter Comparison

Engineering Selection Recommendations

R411800121 (Radiall USA, Inc.): This substitute maintains identical electrical specifications to the main part with the exception of maximum frequency rating (18 GHz versus 26.5 GHz). Both components are manufactured by Radiall USA, Inc., ensuring design consistency and supply chain continuity. ROHS3 compliance and Active product status are maintained. Selection of this substitute is appropriate for applications operating at or below 18 GHz.

SF0929-6200-00 (Amphenol SV Microwave): This substitute provides equivalent electrical performance within the 0 Hz to 18 GHz frequency band. Manufactured by Amphenol SV Microwave, this component maintains ROHS3 compliance and Active product status. The part operates at identical power and impedance specifications. Selection of this substitute is appropriate for applications operating at or below 18 GHz and where multi-source component qualification is required.

Frequently Asked Questions (FAQ)

Q: Can R411800121 or SF0929-6200-00 be used in place of R413800121 in all applications?

A: These substitutes are applicable only in applications where the maximum operating frequency does not exceed 18 GHz. The R413800121 is rated to 26.5 GHz. Applications requiring operation above 18 GHz must use the R413800121 or equivalent parts rated to 26.5 GHz or higher.

Q: Are all three parts electrically equivalent within their respective frequency ranges?

A: Within their specified frequency ranges, all three parts share identical attenuation value (0 dB), power rating (2W), and impedance (50 Ohms). Electrical equivalence is confirmed for these parameters across all three components.

Q: What is the difference between R411800121 and SF0929-6200-00?

A: Both parts operate identically across 0 Hz to 18 GHz with 0 dB attenuation, 2W power, and 50 Ohm impedance in SMA in-line module packaging. The primary difference is manufacturer: R411800121 is manufactured by Radiall USA, Inc., while SF0929-6200-00 is manufactured by Amphenol SV Microwave. Both maintain ROHS3 compliance and Active product status.

Q: Are there any compliance or regulatory differences between these parts?

A: All three parts are ROHS3 compliant and carry EAR99 ECCN classification. Both R413800121 and R411800121 are subject to REACH regulations. SF0929-6200-00 is REACH unaffected. All parts share identical HTSUS classification (8533.21.0090).

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability is limited by frequency range. R411800121 and SF0929-6200-00 are interchangeable with each other for applications operating at or below 18 GHz. Neither can substitute for R413800121 in applications requiring operation above 18 GHz. Physical package compatibility (SMA in-line module) is identical across all three parts.
