Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Critical Parameters for Substitution:

• Attenuation Value: 1dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 64mW (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Frequency Range: Minimum coverage of application requirements

The PAT0816-C-1DB-T5 manufactured by Susumu meets all critical electrical parameters. The frequency range specification differs (0 Hz ~ 10 GHz versus 0 Hz ~ 20 GHz), representing a narrower operational bandwidth. Both parts maintain identical moisture sensitivity classification, RoHS compliance status, and REACH compliance status, ensuring regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TFA16C01DBER and PAT0816-C-1DB-T5 are active production components with identical RoHS3 and REACH compliance certifications. Selection between these parts is determined by application frequency requirements:

TFA16C01DBER (Ohmite): Suitable for applications requiring attenuation across the full 0 Hz to 20 GHz frequency spectrum. This part provides extended high-frequency coverage and is appropriate for broadband RF systems operating at frequencies up to 20 GHz.

PAT0816-C-1DB-T5 (Susumu): Suitable for applications with frequency requirements limited to 0 Hz to 10 GHz. This part is appropriate for RF systems operating within the 10 GHz frequency ceiling and offers equivalent electrical performance within this bandwidth.

Both parts share identical attenuation value, impedance, power rating, package configuration, and regulatory compliance status. The selection decision is based solely on whether the application frequency range requirement exceeds 10 GHz.

Frequently Asked Questions (FAQ)

Q: Can the PAT0816-C-1DB-T5 be used as a direct replacement for the TFA16C01DBER in all applications?

A: The PAT0816-C-1DB-T5 is a direct replacement only for applications with frequency requirements not exceeding 10 GHz. Applications requiring attenuation at frequencies between 10 GHz and 20 GHz require the TFA16C01DBER.

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

A: Yes. Both parts use the 0603 (1608 Metric) package configuration and are mechanically interchangeable at the PCB level.

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

A: Yes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both the TFA16C01DBER and PAT0816-C-1DB-T5 are ROHS3 compliant and REACH unaffected.

Q: What is the primary difference between these two attenuator parts?

A: The primary difference is the maximum frequency specification. The TFA16C01DBER operates to 20 GHz, while the PAT0816-C-1DB-T5 operates to 10 GHz. All other electrical parameters, including attenuation value, impedance, and power rating, are identical.

Q: Can I use the TFA16C01DBER in place of the PAT0816-C-1DB-T5?

A: Yes. The TFA16C01DBER can be used as a substitute for the PAT0816-C-1DB-T5 in any application, as it provides equivalent or superior performance across all specified parameters.
