Substitute Part Grouping Explanation

Substitution of RF attenuators is determined by matching the following critical parameters: attenuation value (5dB), impedance (50 Ohms), power handling (2W), package type (SMA In-Line Module), and frequency range coverage. Substitute parts are grouped into two categories based on frequency range capability:

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

Limited-Range Substitutes (0 Hz ~ 4 GHz or 0 Hz ~ 6 GHz): Parts that provide reduced frequency coverage but maintain all other electrical and mechanical parameters.

All substitute parts maintain 50 Ohm impedance, 2W power rating, 5dB attenuation (or 5.5dB for M3933/16-22N), and SMA In-Line Module packaging. Frequency range limitations determine application suitability within specific system designs.

Engineering Selection Recommendations

Full-Range Substitutes (18 GHz Coverage):

SF0929-6200-05 (Amphenol SV Microwave) provides direct substitution with identical attenuation (5dB), frequency range (0 Hz ~ 18 GHz), power rating (2W), and ROHS3 compliance. This part is recommended for applications requiring complete frequency coverage matching the R413805000 specification.

M3933/16-22N (Cinch Connectivity Solutions Midwest Microwave) covers the full 18 GHz frequency range with 5.5dB attenuation and 2W power handling. This part is RoHS non-compliant and introduces 0.5dB additional attenuation, limiting its use to applications where RoHS compliance is not required and attenuation tolerance permits the deviation.

Limited-Range Substitutes (6 GHz Coverage):

ATS-1M1F-05DB2W (Amphenol RF) and P1AT-SAMF-6G2W-5 (P1dB Inc) both provide 5dB attenuation at 2W with 50 Ohm impedance but operate only to 6 GHz. These parts are suitable for applications operating within the 0 Hz to 6 GHz band and are ROHS3 compliant. P1AT-SAMF-6G2W-5 offers higher inventory availability (1054 units).

Limited-Range Substitute (4 GHz Coverage):

CGA-1040-05-SMA-02 (Cinch Connectivity Solutions) operates to 4 GHz maximum frequency with 5dB attenuation and 2W power rating. This part is ROHS3 compliant and suitable only for applications with frequency requirements not exceeding 4 GHz.

Frequently Asked Questions (FAQ)

Q: Can the SF0929-6200-05 directly replace the R413805000?

A: Yes. The SF0929-6200-05 matches all critical parameters: 5dB attenuation, 0 Hz to 18 GHz frequency range, 2W power handling, 50 Ohm impedance, SMA In-Line Module package, and ROHS3 compliance. Both parts are active in production.

Q: What is the difference between the R413805000 and M3933/16-22N?

A: Both parts cover 0 Hz to 18 GHz with 2W power at 50 Ohms in SMA In-Line Module packaging. The M3933/16-22N provides 5.5dB attenuation (0.5dB higher) and is RoHS non-compliant, whereas the R413805000 is ROHS3 compliant with 5dB attenuation.

Q: Can I use ATS-1M1F-05DB2W in place of R413805000?

A: The ATS-1M1F-05DB2W is suitable only for applications operating within 0 Hz to 6 GHz. It matches the 5dB attenuation, 2W power, 50 Ohm impedance, and SMA In-Line Module package, but does not cover the full 18 GHz frequency range of the R413805000.

Q: What packaging differences exist among these substitute parts?

A: The R413805000 is supplied in Bulk packaging. M3933/16-22N is supplied in Bag packaging. All other substitute parts (SF0929-6200-05, ATS-1M1F-05DB2W, P1AT-SAMF-6G2W-5, CGA-1040-05-SMA-02) are supplied in Bulk packaging.

Q: Are all substitute parts ROHS3 compliant?

A: No. M3933/16-22N is RoHS non-compliant. All other substitute parts (SF0929-6200-05, ATS-1M1F-05DB2W, P1AT-SAMF-6G2W-5, CGA-1040-05-SMA-02) are ROHS3 compliant, matching the R413805000 compliance status.

Q: Which substitute part has the highest inventory availability?

A: P1AT-SAMF-6G2W-5 (P1dB Inc) has 1054 units in stock, the highest among all listed parts. However, this part is limited to 6 GHz frequency coverage.

Q: What attenuation tolerance should I consider when selecting M3933/16-22N?

A: M3933/16-22N provides 5.5dB attenuation compared to the 5dB specification of R413805000. This 0.5dB difference must be evaluated against system attenuation requirements and acceptable tolerance ranges.
