RF Attenuator 9dB 50 Ohm SMA In-Line Module ATS-1M1F-09DB2W

Part Overview

The ATS-1M1F-09DB2W is an RF attenuator manufactured by Amphenol RF, designed for signal attenuation applications across the 0 Hz to 6 GHz frequency range. This active product operates at 50 Ohms impedance with a 2W power handling capacity and provides 9dB attenuation in an SMA in-line module configuration. The component is ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and is classified as REACH affected. Identifying equivalent substitute parts is necessary to ensure supply chain continuity, manage inventory alternatives, and support procurement flexibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ATS-1M1F-09DB2W are identified based on strict parametric equivalence across the following critical specifications:

• Attenuation Value: 9dB (exact match required)
• Frequency Range: 0 Hz ~ 6 GHz (full coverage required)
• Impedance: 50 Ohms (standard RF impedance match)
• Power Rating: 2W (thermal and power handling equivalence)
• Package Configuration: SMA In-Line Module (mechanical and electrical interface compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement match)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The substitute part P1AT-SAMF-6G2W-9 from P1dB Inc meets all these parametric requirements and is therefore classified as a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ATS-1M1F-09DB2W and P1AT-SAMF-6G2W-9 are active products with identical parametric specifications across all critical electrical and mechanical dimensions. Selection between these parts should be based on:

Regulatory Compliance: The ATS-1M1F-09DB2W is REACH affected, while the P1AT-SAMF-6G2W-9 is REACH unaffected. Applications subject to REACH regulations may require the P1dB Inc part to simplify compliance documentation.

Availability and Inventory: Current stock levels differ between manufacturers. The ATS-1M1F-09DB2W has 953 pieces in inventory, while the P1AT-SAMF-6G2W-9 has 812 pieces available. Procurement decisions should account for lead times and supply chain requirements.

Manufacturer Certification: Both parts meet ROHS3 compliance and MSL 1 requirements. No additional testing or qualification is required for direct substitution in applications where the primary part is unavailable.

Frequently Asked Questions (FAQ)

Q: Can the P1AT-SAMF-6G2W-9 be used as a direct replacement for the ATS-1M1F-09DB2W?

A: Yes. Both parts are parametrically equivalent across all critical specifications: 9dB attenuation, 0 Hz to 6 GHz frequency range, 50 Ohm impedance, 2W power rating, and SMA in-line module package. Direct substitution is supported without circuit modification.

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

A: The ATS-1M1F-09DB2W is REACH affected, while the P1AT-SAMF-6G2W-9 is REACH unaffected. Both are ROHS3 compliant. Applications in REACH-regulated regions may benefit from using the P1dB Inc part to reduce compliance complexity.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both parts have MSL 1 (Unlimited) rating, indicating identical handling, storage, and environmental requirements. No difference in moisture sensitivity management is required between the two parts.

Q: What is the mechanical interface compatibility between these parts?

A: Both parts use SMA in-line module configuration, ensuring identical mechanical fit and electrical interface compatibility in existing circuit designs and PCB layouts.

Q: Are there any frequency or power handling limitations when substituting between these parts?

A: No. Both parts operate identically across the full 0 Hz to 6 GHz frequency range with 2W power handling capacity. No derating or frequency-dependent performance differences exist between the two parts.
