Substitute Part Grouping Explanation

Substitute parts for the R413804115 are classified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Attenuation Value: 4dB (exact match required)
Impedance: 50 Ohms (exact match required)
Package / Case: SMA In-Line Module (exact match required)
Power Rating: 2W (exact match or higher acceptable)

Secondary Compatibility Factors:

Frequency Range: Parts with equal or extended frequency coverage are acceptable
RoHS Compliance: ROHS3 compliance preferred for regulatory alignment
ECCN Classification: EAR99 classification maintained across all substitutes

All identified substitute parts meet the primary matching criteria. Variations in frequency range extension and compliance certifications are noted to support application-specific selection requirements.

Engineering Selection Recommendations

ROHS3 Compliant Substitutes (Preferred for Commercial Applications):

The ATS-1M1F-04DB2W (Amphenol RF), CGA-1040-04-SMA-02 (Cinch Connectivity Solutions), and P1AT-SAMF-6G2W-4 (P1dB Inc) maintain ROHS3 compliance matching the original R413804115 specification. These three parts are suitable for applications requiring regulatory compliance with commercial electronics standards. The ATS-1M1F-04DB2W and P1AT-SAMF-6G2W-4 provide extended frequency coverage to 6 GHz, offering operational margin beyond the 4 GHz specification. The CGA-1040-04-SMA-02 maintains identical frequency range specification to the original part.

Military-Grade Alternative:

The M3933/25-66N (Cinch Connectivity Solutions Midwest Microwave) is qualified to MIL-DTL-M3933 military specification and provides extended frequency coverage to 18 GHz. This part is RoHS non-compliant and does not specify power rating or impedance in the provided data. Selection of this part is appropriate for military or aerospace applications where MIL-DTL qualification is required and RoHS compliance is not mandated.

Inventory Availability:

All substitute parts maintain active product status with current inventory levels: ATS-1M1F-04DB2W (861 units), CGA-1040-04-SMA-02 (1127 units), M3933/25-66N (1055 units), and P1AT-SAMF-6G2W-4 (921 units).

Frequently Asked Questions (FAQ)

Q: Can the ATS-1M1F-04DB2W be used as a direct replacement for the R413804115?

A: Yes. The ATS-1M1F-04DB2W meets all primary matching criteria: 4dB attenuation, 50-ohm impedance, 2-watt power rating, and SMA in-line module package. The extended frequency range to 6 GHz provides additional operational capability beyond the 4 GHz specification of the original part.

Q: What is the difference between the CGA-1040-04-SMA-02 and the P1AT-SAMF-6G2W-4?

A: Both parts provide 4dB attenuation, 2-watt power rating, and 50-ohm impedance in SMA in-line module packages with ROHS3 compliance. The CGA-1040-04-SMA-02 operates to 4 GHz, matching the original specification. The P1AT-SAMF-6G2W-4 extends to 6 GHz frequency range. Selection depends on application frequency requirements.

Q: Is the M3933/25-66N suitable for commercial applications?

A: The M3933/25-66N is not ROHS3 compliant and is qualified to military specification MIL-DTL-M3933. This part is appropriate for military and aerospace applications where RoHS compliance is not required. Commercial applications requiring regulatory compliance should select from the ROHS3-compliant alternatives.

Q: Do all substitute parts use the same SMA connector configuration?

A: All identified substitute parts use SMA in-line module packages. The CGA-1040-04-SMA-02 description specifies SMA male to SMA female connector configuration. Connector gender specifications for other parts should be verified against application requirements.

Q: What is the significance of the frequency range differences among substitute parts?

A: The R413804115 operates from 0 Hz to 4 GHz. Substitute parts with extended frequency ranges (ATS-1M1F-04DB2W and P1AT-SAMF-6G2W-4 to 6 GHz; M3933/25-66N to 18 GHz) provide operational capability beyond the original specification. These parts are backward compatible with 4 GHz applications. Selection of extended-range parts does not affect performance within the 0 to 4 GHz band.

Q: Are there packaging differences between substitute parts?

A: The R413804115, ATS-1M1F-04DB2W, CGA-1040-04-SMA-02, and P1AT-SAMF-6G2W-4 are supplied in bulk packaging. The M3933/25-66N is supplied in bag packaging. Packaging format may affect procurement and handling procedures but does not impact electrical or mechanical performance.
