R413802115 RF Attenuator SMA 2dB 4GHz 2W Equivalent & Substitute Parts

Part Overview

The R413802115 is an RF attenuator manufactured by Radiall USA, Inc., designed for in-line attenuation applications in RF and microwave systems. This SMA-connectorized module provides 2dB attenuation across a 0 Hz to 4 GHz frequency range with 50-ohm impedance and 2-watt power handling capability. The part is currently active in production and ROHS3 compliant. Equivalent and substitute parts are identified for applications requiring extended frequency coverage, alternative packaging formats, or inventory availability optimization.

Substitute Part Grouping Explanation

Substitute parts for the R413802115 are qualified based on matching the following critical electrical and mechanical parameters:

Core Matching Criteria:

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

Allowable Variations:

Frequency Range: Substitutes with extended frequency coverage (6 GHz, 12.4 GHz, or 18 GHz) are functionally compatible with the 4 GHz specification, as they operate within and exceed the original frequency band
Packaging Format: Bulk and Bag packaging formats are interchangeable for component-level applications
RoHS Compliance Status: Both ROHS3-compliant and RoHS non-compliant parts are listed; selection depends on end-application regulatory requirements

All substitute parts maintain identical electrical performance within the R413802115 operating frequency range of 0 Hz to 4 GHz.

Engineering Selection Recommendations

For ROHS3-Compliant Applications: Select from ATS-1M1F-02DB2W, P1AT-SAMF-18G2W-2, or SF0929-6200-02. All three parts maintain ROHS3 compliance matching the original R413802115 specification. ATS-1M1F-02DB2W provides 6 GHz frequency coverage in Bulk packaging. P1AT-SAMF-18G2W-2 and SF0929-6200-02 both extend to 18 GHz in Bulk packaging, with SF0929-6200-02 offering the highest inventory availability at 846 units.

For Extended Frequency Coverage: M3933/25-62S and M3933/25-28N from Cinch Connectivity Solutions extend frequency coverage to 18 GHz and 12.4 GHz respectively. These parts are supplied in Bag packaging and are RoHS non-compliant; selection is appropriate for applications without RoHS regulatory requirements.

For Inventory Optimization: M3933/25-28N offers the highest inventory level at 1019 units. P1AT-SAMF-18G2W-2 provides 1053 units with ROHS3 compliance and extended frequency coverage.

For Direct Form-Fit-Function Replacement: ATS-1M1F-02DB2W is the closest substitute, matching Bulk packaging and ROHS3 compliance while providing extended 6 GHz frequency coverage within the same connector and power specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the R413802115 with a part rated for higher frequency coverage?

A: Yes. Parts rated for 6 GHz, 12.4 GHz, or 18 GHz frequency coverage are functionally compatible with the R413802115 4 GHz specification. The attenuator will operate correctly at all frequencies up to 4 GHz. Higher frequency-rated parts do not introduce performance degradation within the original operating band.

Q: What is the difference between Bulk and Bag packaging?

A: Bulk and Bag packaging formats are interchangeable for component-level applications. Packaging selection depends on inventory management and handling procedures. Both formats contain the same electrical component.

Q: Are RoHS non-compliant parts acceptable substitutes?

A: RoHS non-compliant parts (M3933/25-28N and M3933/25-62S) are electrically equivalent substitutes. Selection depends on end-application regulatory requirements. Applications subject to RoHS directives must use ROHS3-compliant alternatives.

Q: Which substitute part provides the best inventory availability?

A: M3933/25-28N offers 1019 units in stock. For ROHS3-compliant alternatives, P1AT-SAMF-18G2W-2 provides 1053 units.

Q: Do all substitute parts maintain 50-ohm impedance and 2-watt power handling?

A: Yes. All listed substitute parts maintain 50-ohm impedance and 2-watt power rating, matching the R413802115 electrical specifications.

Q: Can I use these substitutes in existing designs without modification?

A: Yes. All substitute parts use identical SMA In-Line Module connectors and maintain the same electrical parameters (2dB attenuation, 50-ohm impedance, 2-watt power rating) within the 0 Hz to 4 GHz operating range. No design modifications are required for direct substitution.
