TFA32C01DBER RF Attenuator Equivalent & Substitute Parts

Part Overview

The TFA32C01DBER is a 1206 form factor RF attenuator manufactured by Ohmite, designed for applications requiring 1dB attenuation across a broad frequency range of 0 Hz to 20 GHz. This component operates at 50 Ohms impedance with a power rating of 125mW and is packaged in Tape & Reel format. The part maintains Active product status and carries ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements necessitate alternative sourcing options.

Substitute Part Grouping Explanation

Substitute parts for the TFA32C01DBER are identified based on strict parameter matching across the following critical specifications:

Matching Parameters:

• Attenuation Value: 1dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 125mW (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Packaging Type: Tape & Reel (TR) (exact match required)
• RoHS Status: ROHS3 Compliant (compliance level match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Variable Parameters:

• Frequency Range: The TFA32C01DBER operates across 0 Hz ~ 20 GHz. Substitute parts may operate within a subset of this frequency range while maintaining all other electrical and mechanical specifications. A substitute with a narrower frequency range remains functionally equivalent for applications operating within that narrower band.

The PAT1632-C-1DB-T1 from Susumu meets all matching parameters with a frequency range of 0 Hz ~ 3 GHz, making it suitable for applications requiring attenuation within this frequency band.

Parameter Comparison

Engineering Selection Recommendations

Both the TFA32C01DBER and PAT1632-C-1DB-T1 maintain Active product status and carry identical compliance certifications including ROHS3, REACH Unaffected, and EAR99 export classification. Both components are available in new original condition with established inventory levels.

Selection between these parts depends on application frequency requirements. The TFA32C01DBER supports the full 0 Hz ~ 20 GHz frequency range and is appropriate for broadband RF applications spanning microwave frequencies. The PAT1632-C-1DB-T1 operates within 0 Hz ~ 3 GHz and is suitable for applications limited to this frequency band.

All other electrical characteristics, mechanical specifications, and regulatory compliance parameters are identical between the two parts, ensuring direct substitution capability within the appropriate frequency operating range.

Frequently Asked Questions (FAQ)

Q: Can the PAT1632-C-1DB-T1 be used as a direct replacement for the TFA32C01DBER in all applications?

A: The PAT1632-C-1DB-T1 is a direct mechanical and electrical substitute for applications operating within the 0 Hz ~ 3 GHz frequency range. For applications requiring operation above 3 GHz, the TFA32C01DBER is the appropriate selection due to its extended 20 GHz upper frequency limit.

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

A: Both parts use the 1206 (3216 Metric) package form factor and are supplied in Tape & Reel packaging. They are mechanically interchangeable in PCB layouts designed for this package size.

Q: Do both parts meet the same regulatory requirements?

A: Both the TFA32C01DBER and PAT1632-C-1DB-T1 are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control. They meet identical regulatory and compliance standards.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating, eliminating moisture-related storage constraints.

Q: Are there inventory considerations when selecting between these parts?

A: The TFA32C01DBER has 5572 pieces in stock, while the PAT1632-C-1DB-T1 has 2819 pieces available. Inventory levels may influence procurement decisions based on project timelines and volume requirements.
