ATS-2M2F-20DB2W RF Attenuator Equivalent & Substitute Parts

Part Overview

The ATS-2M2F-20DB2W is an RF attenuator manufactured by Amphenol RF, designed for fixed attenuation applications in RF and microwave systems. This component provides 20dB attenuation across a frequency range of 0 Hz to 6 GHz with 50-ohm impedance and 2-watt power handling capability in an N-Type in-line module configuration. The product is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Parameter	Value
Attenuation Value	20dB
Frequency Range	0 Hz ~ 6 GHz
Power Rating	2W
Impedance	50 Ohms
Package / Case	N-Type In-Line Module
Product Status	Obsolete

Substitute Part Grouping Explanation

Substitution eligibility for the ATS-2M2F-20DB2W is determined by strict adherence to the following electrical and mechanical parameters:

Core Substitution Criteria:

Attenuation Value: 20dB (exact match required)
Impedance: 50 Ohms (exact match required)
Power Rating: 2W (exact match required)
Package / Case: N-Type In-Line Module (exact match required)
Frequency Range: Must encompass or equal the original 0 Hz ~ 6 GHz specification

All identified substitute parts meet these core criteria. Substitute parts with extended frequency ranges (beyond 6 GHz) remain functionally compatible within the original operating bandwidth. Active product status and RoHS compliance are secondary considerations for component selection in applications requiring regulatory adherence.

Engineering Selection Recommendations

For applications operating within 0 Hz to 3 GHz: The LCAT1003-20 (L-com) provides exact frequency coverage matching the lower end of the original specification. This component is active, ROHS3 compliant, and suitable for systems with regulatory compliance requirements.

For applications operating within 0 Hz to 6 GHz: The 05AS102-K20S3 (Rosenberger) and LCAT1007-20 (L-com) both provide frequency coverage exceeding the original 6 GHz specification. Both components are active and RoHS compliant. The 05AS102-K20S3 operates to 18 GHz with RoHS compliance certification. The LCAT1007-20 operates to 18 GHz and is ROHS3 compliant.

For applications operating within 0 Hz to 12.4 GHz: The 53AS102-K20N3 (Rosenberger) provides intermediate frequency coverage and is active with RoHS compliance.

All substitute parts maintain identical electrical specifications (20dB attenuation, 2W power rating, 50-ohm impedance) and mechanical compatibility (N-Type in-line module configuration) with the original ATS-2M2F-20DB2W component.

Frequently Asked Questions (FAQ)

Q: Can the LCAT1003-20 be used as a direct replacement for the ATS-2M2F-20DB2W?

A: The LCAT1003-20 is electrically compatible for applications operating within its 0 Hz to 3 GHz frequency range. However, it does not provide coverage for the full original 6 GHz specification. Selection depends on the actual operating frequency of the application.

Q: What is the difference between the Rosenberger 05AS102-K20S3 and 53AS102-K20N3?

A: Both components provide identical attenuation (20dB), power rating (2W), and impedance (50 ohms). The primary difference is frequency range: the 05AS102-K20S3 operates to 18 GHz, while the 53AS102-K20N3 operates to 12.4 GHz. Both are active and RoHS compliant.

Q: Are all substitute parts mechanically compatible with the original N-Type connector interface?

A: Yes. All substitute parts are specified as N-Type in-line modules, ensuring mechanical compatibility with existing N-Type connector systems.

Q: Which substitute part has the broadest frequency coverage?

A: Both the 05AS102-K20S3 (Rosenberger) and LCAT1007-20 (L-com) provide frequency coverage to 18 GHz, exceeding the original 6 GHz specification.

Q: Are there RoHS compliance differences among the substitute parts?

A: The 05AS102-K20S3 and 53AS102-K20N3 (Rosenberger) are RoHS compliant. The LCAT1003-20 is ROHS3 compliant. The LCAT1007-20 does not specify RoHS status in the provided data. Verify RoHS requirements for your specific application.

Q: Can substitute parts with higher frequency ratings be used in lower-frequency applications?

A: Yes. Substitute parts with extended frequency ranges (such as 18 GHz models) function correctly in applications operating at lower frequencies within their specification range. The attenuation value, power rating, and impedance remain constant across the frequency range.
