TFA16C02DBER RF Attenuator Equivalent & Substitute Parts

Part Overview

The TFA16C02DBER is an active RF attenuator manufactured by Ohmite, designed for high-frequency signal attenuation applications. This 0603 (1608 Metric) surface-mount component provides 2dB attenuation across a frequency range of 0 Hz to 20 GHz with 50-ohm impedance and 64mW power handling capability. The part is currently in active production status and carries ROHS3 compliance certification. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by strict equivalence across critical electrical and mechanical parameters. The TFA16C02DBER and its identified substitute must satisfy the following criteria:

Critical Matching Parameters:

• Attenuation Value: 2dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 64mW (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Packaging Type: Tape & Reel (TR) (exact match required)

Acceptable Parameter Variations:

• Frequency Range: The substitute part may operate within a subset of the main part's frequency range, provided the substitute's upper frequency limit meets or exceeds the application requirement
• Manufacturer: Different manufacturers are acceptable provided all electrical and mechanical parameters align

The PAT0816-C-2DB-T5 (Susumu) qualifies as a parametric equivalent based on matching attenuation, impedance, power rating, and package specifications. The substitute operates across 0 Hz to 10 GHz, which represents a narrower frequency range than the main part's 0 Hz to 20 GHz specification.

Engineering Selection Recommendations

Primary Part: TFA16C02DBER (Ohmite)

The TFA16C02DBER is the primary selection for applications requiring RF attenuation across the full 0 Hz to 20 GHz frequency spectrum. This part maintains active production status and carries full ROHS3 and REACH compliance certifications. Current inventory availability is 4,930 units.

Substitute Part: PAT0816-C-2DB-T5 (Susumu)

The PAT0816-C-2DB-T5 serves as a parametric equivalent for applications operating within the 0 Hz to 10 GHz frequency range. This substitute maintains identical attenuation, impedance, power rating, and package specifications. Both parts carry equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected). The substitute is suitable for component selection when the application frequency requirement does not exceed 10 GHz and when supply or cost considerations favor the Susumu alternative. Current inventory availability is 877 units.

Selection Criteria:

• Select TFA16C02DBER when application frequency requirements extend beyond 10 GHz
• Select PAT0816-C-2DB-T5 when application frequency requirements are limited to 10 GHz or below
• Both parts are suitable for applications operating within the 0 Hz to 10 GHz range
• Both parts satisfy identical compliance and moisture sensitivity requirements

Frequently Asked Questions (FAQ)

Q: Can PAT0816-C-2DB-T5 be used as a direct replacement for TFA16C02DBER in all applications?

A: The PAT0816-C-2DB-T5 is a direct replacement only for applications operating within the 0 Hz to 10 GHz frequency range. Applications requiring attenuation above 10 GHz must use the TFA16C02DBER, which operates to 20 GHz.

Q: Are the physical package dimensions identical between these parts?

A: Yes. Both parts use the 0603 (1608 Metric) package specification and are supplied in Tape & Reel (TR) packaging. PCB footprints and assembly processes are identical.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both TFA16C02DBER and PAT0816-C-2DB-T5 are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What is the impedance specification for both parts?

A: Both parts are specified at 50 ohms impedance, which is the standard for RF and microwave applications.

Q: Are the attenuation and power handling specifications identical?

A: Yes. Both parts provide 2dB attenuation and are rated for 64mW power handling.

Q: What should determine my choice between these two parts?

A: The primary selection criterion is application frequency requirement. If your circuit operates at frequencies above 10 GHz, use TFA16C02DBER. If your circuit operates at 10 GHz or below, either part is suitable based on availability and procurement considerations.
