Substitute Part Grouping Explanation

Substitution eligibility for the R413802000 is determined by the following core parameters:

Primary Matching Criteria:

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

Secondary Consideration:

Frequency Range: Parts with frequency ranges equal to or exceeding 0 Hz ~ 18 GHz are functionally equivalent for applications operating within the 18 GHz upper limit

All identified substitute parts meet the primary matching criteria. Frequency range variations are noted in the parameter comparison table to support application-specific selection.

Engineering Selection Recommendations

Full-Range Equivalents (0 Hz ~ 18 GHz):

The following parts provide complete parametric equivalence to the R413802000 across the full 18 GHz frequency specification:

P1AT-SAMF-18G2W-2 (P1dB Inc): ROHS3 compliant, Active status, 1053 units in stock
SF0929-6200-02 (Amphenol SV Microwave): ROHS3 compliant, Active status, 846 units in stock
M3933/25-62S (Cinch Connectivity Solutions Midwest Microwave): Active status, 739 units in stock (RoHS non-compliant)

Frequency-Limited Equivalents:

M3933/25-28N (Cinch Connectivity Solutions Midwest Microwave): Frequency range limited to 12.4 GHz; suitable for applications not requiring full 18 GHz coverage. RoHS non-compliant, 1019 units in stock.
ATS-1M1F-02DB2W (Amphenol RF): Frequency range limited to 6 GHz; suitable for applications operating below 6 GHz. ROHS3 compliant, 660 units in stock.

Selection should prioritize parts matching both the required frequency range and compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can M3933/25-28N substitute for R413802000 in all applications?

A: M3933/25-28N is a parametric equivalent for applications operating at frequencies up to 12.4 GHz. Applications requiring operation across the full 0 Hz ~ 18 GHz range require a full-range equivalent such as P1AT-SAMF-18G2W-2, SF0929-6200-02, or M3933/25-62S.

Q: What is the difference between ROHS3 compliant and RoHS non-compliant parts?

A: ROHS3 compliant parts meet Restriction of Hazardous Substances Directive requirements. RoHS non-compliant parts do not meet these requirements. Selection depends on application regulatory requirements and end-use market restrictions.

Q: Are all substitute parts available in the same packaging as R413802000?

A: R413802000 is supplied in Bulk packaging. M3933/25-62S and M3933/25-28N are supplied in Bag packaging. P1AT-SAMF-18G2W-2 and SF0929-6200-02 are supplied in Bulk packaging. Packaging differences do not affect electrical or mechanical compatibility.

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

A: ATS-1M1F-02DB2W meets all core electrical and mechanical parameters (2dB, 50 Ohm, 2W, SMA In-Line Module) but operates only to 6 GHz. It is suitable only for applications with frequency requirements at or below 6 GHz.

Q: Which substitute offers the best compliance profile?

A: P1AT-SAMF-18G2W-2 and SF0929-6200-02 both provide ROHS3 compliance with full 18 GHz frequency coverage, matching the R413802000 compliance status while maintaining complete parametric equivalence.
