RF Attenuator 30dB 50 Ohm SMA In-Line Module 320160017

Part Overview

The Seeed Technology Co., Ltd model 320160017 is an RF attenuator module designed for signal attenuation applications across the 0 Hz to 6 GHz frequency range. This component provides 30dB attenuation with 50 Ohm impedance matching and 1W power handling capability in an SMA in-line module package format. The product is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain functional and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of RF attenuator modules is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Attenuation Value: 30dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Package / Case: SMA In-Line Module (mechanical compatibility)
• Power Rating: 1W (minimum requirement)
• RoHS Compliance: Required for regulatory alignment

Allowable Parameter Variance:

• Frequency Range: Substitute frequency range must encompass or exceed the original specification (0 Hz ~ 6 GHz minimum). Extended frequency capability does not disqualify a substitute.

The substitute part AT-130(40) from Hirose Electric Co Ltd meets all mandatory matching criteria and provides extended frequency coverage (0 Hz ~ 18 GHz), making it functionally compatible for applications within the original 6 GHz operating window.

Parameter Comparison

Engineering Selection Recommendations

The AT-130(40) from Hirose Electric Co Ltd is a direct functional substitute for the discontinued 320160017. Selection is based on the following engineering criteria:

Electrical Equivalence: Both components provide identical attenuation (30dB), impedance (50 Ohms), and power handling (1W). The extended frequency range of AT-130(40) (18 GHz vs. 6 GHz) does not introduce incompatibility; it provides additional operational margin for future applications.

Mechanical Compatibility: Both components utilize SMA in-line module packaging, ensuring direct mechanical and connector compatibility in existing designs.

Regulatory Compliance: Both components maintain RoHS compliance and identical moisture sensitivity ratings, satisfying environmental and handling requirements.

Availability Consideration: AT-130(40) is currently in Last Time Buy status with 2,060 units in stock, compared to the discontinued status of 320160017. This availability window should inform procurement planning for long-term supply requirements.

Frequently Asked Questions (FAQ)

Q: Can AT-130(40) be used as a direct replacement for 320160017 in existing designs?

A: Yes. Both components share identical attenuation (30dB), impedance (50 Ohms), power rating (1W), and SMA in-line module packaging. No circuit modifications are required for mechanical or electrical substitution.

Q: Why does AT-130(40) have a higher frequency range (18 GHz vs. 6 GHz)?

A: Extended frequency capability is a design characteristic of the Hirose component. For applications operating within the original 0 Hz to 6 GHz window, the extended range does not affect performance and provides additional operational margin.

Q: Are there any compliance differences between the two components?

A: No. Both components are RoHS compliant with identical moisture sensitivity levels (MSL 1, Unlimited). ECCN and HTSUS classifications are identical.

Q: What is the significance of AT-130(40) being in Last Time Buy status?

A: Last Time Buy status indicates limited remaining production availability. Procurement should prioritize ordering within this window if long-term supply of this substitute is required.

Q: Are the SMA connectors on both components identical?

A: Yes. Both components use SMA in-line module packaging, ensuring mechanical and connector compatibility without adapter requirements.

Q: Can frequency range differences affect circuit performance?

A: No, within the original operating specification. The 320160017 operates to 6 GHz; AT-130(40) operates to 18 GHz. Applications using frequencies up to 6 GHz will experience identical attenuation and impedance characteristics.
