Substitute Part Grouping Explanation

Substitute parts for the R411802000 are qualified based on the following critical parameters:

Matching Criteria:

Attenuation Value: 2dB (exact match required)
Power Rating: 2W (exact match required)
Impedance: 50 Ohms (exact match required)
Package / Case: SMA In-Line Module (exact match required)

Frequency Range Consideration: The R411802000 operates across 0 Hz ~ 15 GHz. Substitute parts are grouped by their frequency range capability. Parts with frequency ranges equal to or exceeding 15 GHz provide full operational compatibility. Parts with lower frequency ranges (6 GHz or 12.4 GHz) operate within a subset of the original specification and are identified as frequency-limited substitutes.

Compliance Status: RoHS compliance status is documented for each part. ROHS3-compliant substitutes are preferred for regulatory alignment with the main part.

Engineering Selection Recommendations

Tier 1 Substitutes (Full Specification Alignment):

Parts P1AT-SAMF-18G2W-2 and SF0929-6200-02 provide complete electrical and compliance equivalence to the R411802000. Both parts operate across 0 Hz ~ 18 GHz, exceeding the original 15 GHz specification, and maintain ROHS3 compliance. These parts are suitable for direct substitution without operational limitations.

Tier 2 Substitutes (Frequency-Limited):

Part M3933/25-62S operates across 0 Hz ~ 18 GHz with matching electrical parameters but carries RoHS non-compliant status. This part is suitable for applications where RoHS compliance is not a regulatory requirement.

Part M3933/25-28N operates across 0 Hz ~ 12.4 GHz, providing reduced frequency coverage compared to the R411802000. This part is suitable only for applications operating within the 0 Hz ~ 12.4 GHz band. RoHS non-compliant status applies.

Tier 3 Substitute (Frequency-Constrained):

Part ATS-1M1F-02DB2W operates across 0 Hz ~ 6 GHz, providing the most limited frequency coverage. This part is suitable only for applications operating within the 0 Hz ~ 6 GHz band. ROHS3 compliance is maintained.

Frequently Asked Questions (FAQ)

Q: Can ATS-1M1F-02DB2W be used as a direct replacement for R411802000?

A: ATS-1M1F-02DB2W matches the attenuation, power, impedance, and package specifications of the R411802000. However, its frequency range is limited to 0 Hz ~ 6 GHz, compared to the R411802000's 0 Hz ~ 15 GHz range. Use this part only if your application operates entirely within the 0 Hz ~ 6 GHz band.

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

A: Both parts are manufactured by Cinch Connectivity Solutions Midwest Microwave and share identical attenuation, power, impedance, and package specifications. The primary difference is frequency range: M3933/25-62S operates to 18 GHz, while M3933/25-28N operates to 12.4 GHz. Both parts are RoHS non-compliant.

Q: Are there RoHS3-compliant alternatives to the R411802000?

A: Yes. P1AT-SAMF-18G2W-2 (P1dB Inc) and SF0929-6200-02 (Amphenol SV Microwave) are both ROHS3 compliant and provide full frequency coverage to 18 GHz with matching electrical specifications.

Q: Does frequency range affect substitution suitability?

A: Frequency range is a critical parameter. A substitute part with a lower frequency range than the R411802000 (15 GHz) can only be used in applications operating within that lower range. Substitute parts with frequency ranges equal to or exceeding 15 GHz provide full operational compatibility.

Q: What packaging formats are available for these substitutes?

A: All substitute parts use the SMA In-Line Module package format, matching the R411802000. Packaging material (Bulk or Bag) does not affect electrical or mechanical compatibility.

Q: Which substitute part has the highest inventory availability?

A: P1AT-SAMF-18G2W-2 has the highest inventory with 1053 pieces in stock, followed by M3933/25-28N with 1019 pieces.
