TFA20C01DBER RF Attenuator Equivalent & Substitute Parts

Part Overview

The TFA20C01DBER is an active 0805 RF attenuator manufactured by Ohmite, designed for high-frequency signal attenuation applications. This component provides 1dB attenuation across a frequency range of 0 Hz to 20 GHz with 50-ohm impedance and 100mW power handling capability in a compact 0805 (2012 Metric) surface-mount package. The part maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent substitute parts are identified for applications requiring alternative sourcing, inventory management, or extended frequency range capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFA20C01DBER are qualified based on matching the following critical electrical and mechanical parameters:

• Attenuation Value: 1dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 100mW (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling requirement)
• Product Status: Active (availability requirement)

Frequency range variations are permitted within the substitute group when all other parameters remain constant. Substitute parts meeting these criteria are electrically and mechanically interchangeable for the specified application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts in this equivalency group maintain active product status with full ROHS3 compliance and identical moisture sensitivity ratings. Selection between TFA20C01DBER, ATS2012-1DB-T05, and PAT1220-C-1DB-T5 is determined by application frequency requirements and inventory availability.

TFA20C01DBER (Ohmite): Primary selection for applications operating within 0 Hz to 20 GHz frequency range. Current inventory: 5035 pieces.

ATS2012-1DB-T05 (Susumu): Extended frequency capability to 30 GHz supports applications requiring higher frequency operation. Electrical and mechanical parameters remain identical to primary part. Current inventory: 1153 pieces.

PAT1220-C-1DB-T5 (Susumu): Frequency range limited to 0 Hz to 10 GHz. Suitable for applications operating exclusively within this bandwidth. Current inventory: 3000 pieces.

All parts share identical attenuation value, impedance, power rating, package configuration, and compliance certifications. Substitution is valid across all three parts when application frequency requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can ATS2012-1DB-T05 replace TFA20C01DBER in all applications?

A: Yes, when the application operates within the 0 Hz to 20 GHz frequency range. The ATS2012-1DB-T05 extends to 30 GHz, making it suitable for any frequency requirement covered by the TFA20C01DBER. All electrical and mechanical parameters are identical.

Q: What are the limitations of PAT1220-C-1DB-T5 as a substitute?

A: The PAT1220-C-1DB-T5 frequency range is limited to 0 Hz to 10 GHz. This part is suitable only for applications operating exclusively within this bandwidth. Applications requiring operation above 10 GHz must use TFA20C01DBER or ATS2012-1DB-T05.

Q: Are all three parts mechanically identical?

A: Yes. All three parts use the 0805 (2012 Metric) package in Tape & Reel (TR) configuration. PCB footprint and assembly requirements are identical across all parts.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. TFA20C01DBER, ATS2012-1DB-T05, and PAT1220-C-1DB-T5 all maintain ROHS3 compliance, MSL 1 (Unlimited) rating, and active product status.

Q: What is the primary difference between these three attenuators?

A: The primary difference is frequency range capability. TFA20C01DBER operates to 20 GHz, ATS2012-1DB-T05 extends to 30 GHz, and PAT1220-C-1DB-T5 is limited to 10 GHz. Attenuation value, impedance, power rating, and package are identical.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, when frequency requirements are satisfied. All three parts share identical 0805 (2012 Metric) package dimensions and Tape & Reel (TR) packaging format, enabling direct substitution without PCB redesign.
