RF Attenuator 6806.01.A Equivalent & Substitute Parts

Part Overview

The 6806.01.A is an RF attenuator manufactured by Huber+Suhner, Inc., designed for inline attenuation applications in RF and microwave systems. This component provides 6dB attenuation across a frequency range of 0 Hz to 4 GHz with 50 Ohm impedance and 2W power handling capability. The part is housed in a BNC in-line module package and maintains Active product status. Alternative equivalent parts are necessary to support supply chain flexibility, inventory management, and procurement options from multiple qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by strict equivalence across five critical parameters: attenuation value, frequency range, impedance, power rating, and package configuration. All substitute parts must match these specifications exactly to ensure functional and mechanical compatibility within the target application.

Critical Parameters for Substitution:

• Attenuation Value: 6dB (exact match required)
• Frequency Range: 0 Hz ~ 4 GHz (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 2W (exact match required)
• Package: BNC In-Line Module (exact match required)

The substitute parts listed below meet all five criteria and are therefore direct functional equivalents to the 6806.01.A.

Parameter Comparison

Engineering Selection Recommendations

Full Equivalents (Recommended for Direct Substitution):

CT3369A-06 and PE7437-6 are complete parametric equivalents to the 6806.01.A. Both parts match all five critical parameters: 6dB attenuation, 0 Hz to 4 GHz frequency range, 50 Ohm impedance, 2W power rating, and BNC in-line module package. Both maintain Active product status. CT3369A-06 carries ROHS3 compliance certification. PE7437-6 carries RoHS compliance certification. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Non-Equivalent Part (Not Recommended for Direct Substitution):

PE7438-6 differs from the 6806.01.A in impedance specification: PE7438-6 is rated at 75 Ohms while the 6806.01.A requires 50 Ohms. This impedance mismatch prevents direct substitution and will result in signal reflection and impedance discontinuity in 50 Ohm systems. PE7438-6 is suitable only for applications specifically designed for 75 Ohm impedance networks.

Frequently Asked Questions (FAQ)

Q: Can PE7438-6 be used as a substitute for 6806.01.A?

A: No. PE7438-6 has 75 Ohm impedance while 6806.01.A requires 50 Ohm impedance. The impedance mismatch makes this part incompatible for direct substitution in 50 Ohm systems.

Q: What are the approved direct substitutes for 6806.01.A?

A: CT3369A-06 (Cal Test Electronics) and PE7437-6 (Pasternack) are approved direct substitutes. Both match all critical parameters: 6dB attenuation, 0 Hz to 4 GHz frequency range, 50 Ohm impedance, 2W power rating, and BNC in-line module package.

Q: Are there compliance or certification differences between the approved substitutes?

A: CT3369A-06 carries ROHS3 compliance. PE7437-6 carries RoHS compliance. Both are REACH Unaffected and EAR99 classified. Selection between these two should be based on specific compliance requirements of the end application.

Q: What determines whether a part can substitute for 6806.01.A?

A: Five parameters must match exactly: attenuation value (6dB), frequency range (0 Hz to 4 GHz), impedance (50 Ohms), power rating (2W), and package type (BNC in-line module). Any deviation in these parameters disqualifies the part as a direct substitute.

Q: Is the BNC connector type the same across all approved substitutes?

A: Yes. All approved substitutes (CT3369A-06 and PE7437-6) use the same BNC in-line module package configuration as the 6806.01.A, ensuring mechanical and electrical compatibility.
