PAT0816-C-2DB-T5 Equivalent & Substitute Parts

Part Overview

The PAT0816-C-2DB-T5 is an RF attenuator manufactured by Susumu, designed for signal attenuation applications across microwave frequencies. This active product operates across the 0 Hz to 10 GHz frequency range with a fixed attenuation value of 2dB and 50 Ohm impedance matching. The component is packaged in the 0603 (1608 Metric) form factor and is rated for 64mW power dissipation.

Equivalent substitute parts are identified when alternative manufacturers offer RF attenuators with matching electrical specifications and mechanical compatibility. Substitute identification ensures design flexibility, supply chain continuity, and access to alternative inventory sources without requiring circuit redesign.

Substitute Part Grouping Explanation

Substitution of the PAT0816-C-2DB-T5 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Attenuation Value: 2dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 64mW (minimum threshold)
• Frequency Range: Must encompass or exceed 0 Hz ~ 10 GHz operating band

Mechanical Equivalence Criteria:

• Package / Case: 0603 (1608 Metric) form factor (exact match required)
• Packaging Type: Tape & Reel (TR) format

Compliance Equivalence Criteria:

• RoHS3 Compliance (mandatory for environmental standards)
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

The TFA16C02DBER from Ohmite meets all substitution criteria with identical electrical specifications and mechanical compatibility. The substitute part extends the frequency range to 20 GHz, providing additional operational margin beyond the minimum 10 GHz requirement.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (PAT0816-C-2DB-T5): The Susumu PAT0816-C-2DB-T5 is suitable for applications requiring RF attenuation within the 0 Hz to 10 GHz band. This part maintains active product status with full RoHS3 compliance and REACH unaffected classification. Current inventory availability is 877 pieces in new original condition.

Substitute Part Selection (TFA16C02DBER): The Ohmite TFA16C02DBER provides direct electrical and mechanical substitution with extended frequency coverage to 20 GHz. This part is also active, RoHS3 compliant, and REACH unaffected. Inventory availability is 4930 pieces in new original condition, providing enhanced supply chain access.

Selection Basis: Both parts satisfy identical compliance requirements (RoHS3, REACH unaffected, EAR99 classification) and are classified as active products. The choice between primary and substitute parts is determined by supply availability, lead time requirements, and frequency margin requirements. The Ohmite substitute provides additional frequency headroom without electrical or mechanical compromise.

Frequently Asked Questions (FAQ)

Q: Can the TFA16C02DBER replace the PAT0816-C-2DB-T5 in existing designs?

A: Yes. The TFA16C02DBER is a direct substitute with identical attenuation (2dB), impedance (50 Ohms), power rating (64mW), and package form factor (0603 / 1608 Metric). No circuit modifications are required for PCB layout or electrical design.

Q: What is the significance of the extended frequency range in the Ohmite part?

A: The TFA16C02DBER operates to 20 GHz, compared to the Susumu part's 10 GHz maximum. This extended range provides additional operational margin for applications approaching the upper frequency limit. Both parts are fully functional within the 0 Hz to 10 GHz band.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the PAT0816-C-2DB-T5 and TFA16C02DBER are supplied in Tape & Reel (TR) format, suitable for automated assembly processes and production environments.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: What is the primary reason to consider the substitute part?

A: Supply chain continuity and inventory availability. The Ohmite TFA16C02DBER maintains 4930 pieces in stock compared to 877 pieces for the Susumu part, providing enhanced access to inventory and reduced lead time risk.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts deliver identical attenuation (2dB), impedance matching (50 Ohms), and power dissipation capability (64mW) within the 0 Hz to 10 GHz operating band. The Ohmite part's extended frequency specification does not affect performance in the specified operating range.
