RF Attenuator 10dB 50 Ohm SMA In-Line Module 113990031

Part Overview

The Seeed Technology Co., Ltd model 113990031 is an RF attenuator designed for RF signal conditioning applications across the 0 Hz to 3 GHz frequency range. This component provides 10dB attenuation with 50 Ohm impedance matching and 1W power handling capability in an SMA in-line module package format. The part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing system support and new designs. Equivalent alternatives are available from active manufacturers including Crystek Corporation, Huber+Suhner, Hirose Electric, and Radiall USA.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 113990031 is determined by the following critical parameters: attenuation value (10dB), impedance (50 Ohms), power rating (1W), and package format (SMA in-line module). The frequency range defines the operational bandwidth but does not restrict substitution when the alternative part covers the required 0 Hz to 3 GHz specification or exceeds it.

Substitute parts are grouped into two categories:

Direct Functional Equivalents: Parts meeting all core parameters including 10dB attenuation, 50 Ohm impedance, 1W power handling, and SMA in-line module packaging with frequency coverage at or above 0 Hz to 3 GHz.

Parametric Equivalents with Extended Specifications: Parts meeting core electrical parameters but offering extended frequency range (6 GHz to 67 GHz) or minor attenuation variance (11dB). These components are electrically compatible within the 0 Hz to 3 GHz operating window of the original part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Equivalent): CATTEN-0100 from Crystek Corporation provides identical electrical and mechanical specifications to the 113990031, including matching 10dB attenuation, 0 Hz to 3 GHz frequency range, 1W power rating, and SMA in-line module packaging. This part is in active production status with ROHS3 compliance certification and 824 units in current inventory.

Secondary Substitutes (Extended Frequency Coverage): The 6810.19.A (Huber+Suhner), AT-110-WP1(40) (Hirose Electric), and R413V10000 (Radiall) are electrically compatible within the 0 Hz to 3 GHz operating band while offering extended frequency range capabilities (18 GHz and 67 GHz respectively). These components maintain 10dB attenuation, 50 Ohm impedance, 1W power handling, and SMA in-line module format. All three are in active production status.

Parametric Equivalent with Attenuation Variance: R411810124 (Radiall USA) matches all core parameters with 10dB attenuation and 0 Hz to 6 GHz frequency coverage. R411811124 (Radiall USA) provides 11dB attenuation (1dB variance) across 0 Hz to 6 GHz and is suitable only when the 1dB attenuation difference is acceptable to system design specifications.

Compliance Considerations: All substitute parts maintain EAR99 ECCN classification and 8533.21.0090 HTSUS coding consistent with the original component. RoHS and REACH compliance status varies by manufacturer; verify compliance requirements for specific applications before selection.

Frequently Asked Questions (FAQ)

Q: Can CATTEN-0100 directly replace 113990031 in existing designs?

A: Yes. CATTEN-0100 provides identical attenuation (10dB), frequency range (0 Hz to 3 GHz), impedance (50 Ohms), power rating (1W), and SMA in-line module packaging. The component is in active production with ROHS3 compliance.

Q: What is the difference between the 113990031 and R413V10000?

A: Both components provide 10dB attenuation, 50 Ohm impedance, 1W power handling, and SMA in-line module packaging. R413V10000 extends the frequency range to 67 GHz compared to the 3 GHz specification of 113990031. Within the 0 Hz to 3 GHz operating window, both components are functionally equivalent.

Q: Is R411811124 a suitable substitute if only 11dB attenuation is available?

A: R411811124 provides 11dB attenuation instead of the specified 10dB. This 1dB variance must be evaluated against system design tolerances. The component matches all other parameters: 50 Ohm impedance, 1W power rating, SMA in-line module format, and 0 Hz to 6 GHz frequency coverage.

Q: What packaging options are available for these substitutes?

A: All substitute parts are supplied in SMA in-line module format, matching the original 113990031 package type. CATTEN-0100 and Radiall components are supplied in bulk packaging. Hirose AT-110-WP1(40) packaging specification is not detailed in available data.

Q: Are there frequency range limitations when substituting with extended-range parts?

A: No. Parts with extended frequency ranges (6810.19.A at 18 GHz, AT-110-WP1(40) at 18 GHz, R413V10000 at 67 GHz) fully cover the 0 Hz to 3 GHz requirement of the original component. Extended range does not restrict substitution.

Q: What is the inventory status of substitute parts?

A: CATTEN-0100: 824 units; 6810.19.A: 847 units; AT-110-WP1(40): 813 units; R411810124: 1043 units; R411811124: 875 units; R413V10000: 850 units. All substitutes are available in current inventory.
