RF Attenuator 6802.19.A Equivalent & Substitute Parts

Part Overview

The Huber+Suhner 6802.19.A is an RF attenuator module designed for inline signal attenuation in RF and microwave systems. This active product operates across the 0 Hz to 18 GHz frequency range with 2 dB attenuation, 50 ohm impedance, and 2 watt power handling capability in an SMA connector configuration. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical form factors to enable component interchangeability in system designs.

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuator modules is determined by five critical parameters: attenuation value, frequency range coverage, power handling capacity, impedance rating, and physical package type. All substitute parts listed maintain the core 2 dB attenuation specification and 50 ohm impedance required for direct replacement. The frequency range and power rating must meet or exceed the application requirements. All candidates are packaged as SMA in-line modules, ensuring mechanical and electrical compatibility with the original part's connector interface.

Substitute parts are grouped into two categories based on frequency range coverage:

Full-Range Coverage (0 Hz ~ 18 GHz): Parts that match the complete frequency specification of the main part.

Reduced-Range Coverage (0 Hz ~ 6 GHz or 0 Hz ~ 12.4 GHz): Parts with narrower frequency ranges suitable for applications not requiring full 18 GHz bandwidth.

Frequently Asked Questions (FAQ)

Q: Can the ATS-1M1F-02DB2W substitute for the 6802.19.A in all applications?

A: The ATS-1M1F-02DB2W is electrically equivalent for attenuation, power, and impedance specifications. However, its frequency range extends only to 6 GHz, compared to the 6802.19.A's 18 GHz range. Substitution is valid only for applications operating below 6 GHz.

Q: What is the difference between M3933/25-62S and M3933/25-28N?

A: Both parts are manufactured by Cinch Connectivity Solutions Midwest Microwave with identical attenuation, power, and impedance ratings. The M3933/25-62S operates to 18 GHz, while the M3933/25-28N operates to 12.4 GHz. Selection depends on the maximum frequency requirement of the application.

Q: Are all substitute parts available in the same packaging as the 6802.19.A?

A: All substitute parts use SMA in-line module packaging, ensuring mechanical compatibility. The 6802.19.A is supplied in bulk packaging, while M3933/25-62S and M3933/25-28N are supplied in bag packaging. This does not affect electrical or mechanical performance.

Q: Which substitute parts have ROHS3 compliance?

A: P1AT-SAMF-18G2W-2, SF0929-6200-02, and ATS-1M1F-02DB2W are ROHS3 compliant. M3933/25-62S and M3933/25-28N are RoHS non-compliant.

Q: Which substitute parts are REACH unaffected?

A: P1AT-SAMF-18G2W-2, SF0929-6200-02, and the main part 6802.19.A are REACH unaffected. M3933/25-62S, M3933/25-28N, and ATS-1M1F-02DB2W have REACH affected or unspecified status.

Q: Can I use the P1AT-SAMF-18G2W-2 as a direct replacement for the 6802.19.A?

A: Yes. The P1AT-SAMF-18G2W-2 matches all critical electrical parameters: 2 dB attenuation, 0 Hz to 18 GHz frequency range, 2 watt power rating, 50 ohm impedance, and SMA in-line module package. Both parts are active products.

Q: What inventory levels are available for each substitute part?

A: Inventory levels vary: M3933/25-28N (1019 pcs), P1AT-SAMF-18G2W-2 (1053 pcs), SF0929-6200-02 (846 pcs), M3933/25-62S (739 pcs), 6802.19.A (749 pcs), and ATS-1M1F-02DB2W (660 pcs).
