ATS-2M2F-30DB2W RF Attenuator Equivalent & Substitute Parts

Part Overview

The ATS-2M2F-30DB2W is an RF attenuator manufactured by Amphenol RF, designed for fixed attenuation applications across RF and microwave systems. This component provides 30dB attenuation across a frequency range of 0 Hz to 6 GHz with 50 Ohm impedance and 2W power handling capability in an N-Type in-line module configuration.

The ATS-2M2F-30DB2W is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system compatibility, ensure continued availability for production and repair applications, and evaluate alternative active products that meet or exceed the original specifications.

Substitute Part Grouping Explanation

Substitute parts for the ATS-2M2F-30DB2W are selected based on strict equivalence of core electrical and mechanical parameters. The substitution logic is based on the following criteria:

Primary Matching Parameters:

• Attenuation Value: 30dB (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)

Secondary Consideration:

• Frequency Range: The original part operates 0 Hz ~ 6 GHz. Substitute parts with equal or extended frequency ranges maintain full compatibility within the original operating band.

Two substitute parts meet these criteria:

1. ATT-0218-30-NNN-02 (Cinch Connectivity Solutions Midwest Microwave) – Direct manufacturer equivalent with extended frequency range to 12.4 GHz and active product status.

2. LCAT1003-30 (L-com) – Parametric equivalent with reduced frequency range to 3 GHz and active product status.

Engineering Selection Recommendations

ATT-0218-30-NNN-02 (Cinch Connectivity Solutions Midwest Microwave):

This part is the primary substitute for the ATS-2M2F-30DB2W. It maintains all core electrical parameters (30dB attenuation, 2W power, 50 Ohm impedance) and mechanical form factor (N-Type in-line module). The extended frequency range to 12.4 GHz provides operational coverage beyond the original 6 GHz specification. The part carries active product status, ensuring long-term availability. RoHS compliance and MSL 1 rating indicate modern manufacturing standards and handling requirements.

LCAT1003-30 (L-com):

This part is a parametric equivalent suitable for applications operating within the 0 Hz to 3 GHz frequency band. It maintains all core electrical parameters and mechanical form factor. The reduced frequency range to 3 GHz represents a limitation compared to the original ATS-2M2F-30DB2W specification. This part is appropriate for systems with frequency requirements not exceeding 3 GHz. Active product status and ROHS3 compliance indicate current manufacturing and environmental standards.

Selection Guidance:

For applications requiring the full 0 Hz to 6 GHz operating range of the original part, ATT-0218-30-NNN-02 is the appropriate selection. For applications with frequency requirements limited to 3 GHz or below, LCAT1003-30 provides a valid alternative. Both substitute parts are active products with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can ATT-0218-30-NNN-02 be used as a direct replacement for ATS-2M2F-30DB2W?

A: Yes. Both parts share identical attenuation (30dB), power rating (2W), impedance (50 Ohms), and package type (N-Type in-line module). The extended frequency range of ATT-0218-30-NNN-02 (0 Hz ~ 12.4 GHz) encompasses the original operating band (0 Hz ~ 6 GHz), ensuring full compatibility.

Q: What is the key limitation of LCAT1003-30 compared to the original ATS-2M2F-30DB2W?

A: LCAT1003-30 has a reduced frequency range of 0 Hz ~ 3 GHz, compared to the original 0 Hz ~ 6 GHz. This part is suitable only for applications operating within the 3 GHz limit. All other electrical and mechanical parameters are equivalent.

Q: Are there any handling or storage differences between the original part and the substitutes?

A: The original ATS-2M2F-30DB2W lists Moisture Sensitivity Level as Not Applicable. Both substitute parts carry MSL 1 (Unlimited), indicating standard handling and storage conditions with no moisture sensitivity restrictions.

Q: Do the substitute parts meet current environmental compliance standards?

A: Yes. ATT-0218-30-NNN-02 is RoHS Compliant. LCAT1003-30 is ROHS3 Compliant. Both parts meet current environmental and regulatory requirements.

Q: What is the primary reason to select one substitute over the other?

A: Selection depends on the frequency requirements of the application. For systems requiring operation up to 6 GHz, select ATT-0218-30-NNN-02. For systems with maximum frequency requirements of 3 GHz or below, LCAT1003-30 is acceptable and may offer alternative sourcing options.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts use the N-Type in-line module package configuration, ensuring mechanical compatibility in standard RF system installations.
